Hello, Adrian, good to know your channel. I've worked in Samsung's Customer Service for years, here in Brazil, and I've seen thousands of defective TV sets like these, from series E, EH, F and FH. Just to your knowledge, series EH and FH (and all series with xH mark) are refurbished and "testing" models. You can notice that just by looking into EH and FH, some models (at least in Brazil) are exactly the same, with few modifications on PSU and main board. This problem with LED bars happens because the PSU always have a bigger voltage than expected, when the client changes the parameter "Backlight" in the menu to the maximum, the voltage in this particular model goes up to 140VDC at some point, with peaks between 100~125VDC. What I usually did is changing some resistors in the PSU to put down the voltage to maximum 100VDC on the inverter, because this LED bars gets REALLY hot when in use, and often the client comes back with the same problem. It happened four times with a client, who used to connect to an Xbox 360 and gaming for hours, and I have to modify the PSU to not destroy more LED bars. And, please, be careful with the live cell (the LCD display, it's the name that they give to it, don't ask me why :P ). The good way to mount it back is the opposite way that you dismounted in the video, putting the live cell for last, allign it, because or break it when you are moving, or break it when try to close the outer frame. My personal experience when I started to work on this repairs. Congratulations, and thanks. P.S.: I've forgot to mention: the SamyGo projetc have lots of documentation about hacking Samsung TV's, BD players and home-theaters, how to access the TV through serial port and more. Good Luck!

[@ro90401]

Invaluable tech info you give here. Thank you, thank you, thank you!

[@ronb6182]

Lower voltage is the key. Things lasted longer when we had 110 or 115 volts ac. Now days line voltages are 125 and even higher, I had issues with my led Christmas light strings, I would lose at least 4 in one months time. I bought a voltage reducer by apc the ones that make ups for compters. Now nothing burns out I haven't changed a bulb in at least 3 years. When I go solar I will keep in mind to get a Prue sine wave inverter that only puts out 110 volts I think there is an inverter that has a 105 volt setting I won't use that for motors or or motor driven appliances. Well enough on this.

[@thebraziliannutshell6650]

@aleon1018 I have to tell you that was the best chice, new LED sets are more reliable than replacing each single one.

[@thebraziliannutshell6650]

@@ronb6182 Great advice. I'm used to put no-breaks and modify those units to a maximum 105/110VAC on the output too. Thank you!

[@ronb6182]

@kcotte59 I use a Line-R 1200 by APC the same company that make Computer UPS s. I can use 1200 watts of LED lighting. The reason a mentioned a power inverter if I decide to go solar. There is one inverter that has multiple output voltages 105 to 125 vac pure sine wave.

[@roseparini4202]

I found it interesting and educational despite whether or not it was fixed. I agree with your decision to save reusable parts and trash the rest. I'm the curious type that loves this type of challenge. I've saved a ton of money over the years just by investigating. An example: A very expensive Wagner Paint Sprayer. Bought at a home resources center that sells used building supplies. Paid $8.00 Appeared to have been used once and not cleaned properly. I soaked a rag in laquer thinner, wrapped around parts to soften enough to remove. Then soaked and wire and toothbrush cleaned. Sprayed cleaned parts with silicone. Put back together and used it for approximately 5 years. Painted house, fence, bi fold doors, garage overhead door, decks etc. Wagner is known to readily give out if not given pristine cleaning and re silicone moving parts. Idk. Some might have the money to buy for 1x use and toss but not me. I was widowed at a young age and proud, as a female, to have learned so many money saving skills. My uncle taught me many and after he passed I turned to you tube. So, thank you so so much for taking your time to video this great presentation. I will be subscribing and tuning in again. I'm 70 y.o. now so not as actively repairing things anymore but at times still tackle projects that appeal to my love of a challenge. Thank you again!!

[@catgirl_eva]

I think it's worth trying to fix. If the new LED strips bring the TV back to life, you have yourself a $20 TV. Worst case is that you're out $20. The fact that it's a 1080p TV makes it more worth it, since most 32" sets seem to be 720p these days.

[@piecingtogethergamingpcs]

I 100% agree, that TV is worth $20 to fix it. it a good brand too samsung, I have a 1080p 144 hrz monitor on my gaming PC and the thing been a great monitor, the wife bought a MSI brand 4 years ago same time same specs and that one is in the trash heap already.

[@dennishassler605]

I have an Insignia TV from Best Buy for an Airbnb House and it's lasted for several years, but the on-off switch went out. It's hard to fix, BUT I saw a video on replacing that switch as long as I can find the part. I did replace the TV with a higher quality one, BUT I'll replace the switch and fix it when I am able to find the time - shouldn't take long.

[@warrencampbell6652]

Hi Adrian I believe you said that your power supply was set to 9 volts, If so you should not test individual bulbs with it set to 9 volts. This would explain why led's were blowing up as you went along during your testing. You can supply 3 volts max per bulb times the number of bulbs in series and find quite quickly which row is the problem, then when you find the faulty row reset your power supply to 3 volts max and go looking for the problem , one led at a time. I don't think I heard you explain to viewers for them to dial back their power supplies. I am a technician of 45 years. Hope this helps people out. W

[@TotalWipeOut]

I say fix it! Watching your method to determine the issue is really interesting. I really enjoyed the video.

[@LeBoxMan]

I had the exact same problem on my TV that is the exact same model, one day from nowhere the Screen turned black and that was it 💔 only 3 years of use, I had an idea what could it be so I took it apart, after checking the 2 boards (Main and AC Board) didn’t see any issues. At that moment I was 100% sure was back Light LEDs issue, ordered the LEDs stripes replaced them and problem solved 💜 Also I used 3 9V Batteries to test the complete stripes from the (+ -) test area at the beginning of the stripes and showed me some LEDs were dead, it was a quicker and easier way to do it without his tools (Tester).

[@resrussia]

I encourage you complete the repair. I enjoy watching your adventures in repair electronics and your solutions to issues that arise during the process. I learn a lot about electronics and how electronic gadgets work from watching your videos.

[@vincentferrari]

Go for it! I thought this was really interesting and would love to see it turn on. It’s not what you normally do as far as videos but I really dug it.

[@hitone4319]

Great educational video! And Thank You for NOT using background sound/ racket so common these days!

[@winsomehax]

I had an LG 32inch LCD suddenly went dark but the sound was on. After a quick checklist... I figured the LED backlights had gone. $17 on AliExpress and a couple of weeks... they arrived. I'm not particularly good with electronics... but after watching some KZbin videos on similar TVs... and two hours of fiddling later... I had the new LEDs fitted and nervously switched it on. Nothing. Quick check. I'd forgotten to plug one of the two ribbon connectors from the TCON module to the panel. So that's good news... tried again... and BINGO! It worked. Great sense of achievement. Even if it is a simple fix to experienced types.

[@PoxyBear]

You have to start somewhere plus you now have more confidence to fix other things.

[@peterduxbury927]

Its the greatest feeling in the world to revive something that is 'dead'. We all began fixing the simpler things.... So well done! Greetings from Australia.

[@russellwalker9177]

Well Done!! You are right, fixing stuff that others have given up on is a personal triumph.

[@t0nito]

You can replace the individual LEDs instead of the whole strip and it would be cheaper, also if you get to fix it, set the backlight to 80/85% to preserve them. People tend to have the backlight at 100% but 100% drives them hard and will kill them in a short time.

[@servidor712]

thanks for sharing your knowledge; what kind of welder do you recommend to only change a led without damaging it. thanks

[@marcviej.5635]

I'd recommend a TIG welder if you're experienced, if not just go with a stick welder

[@vincemajestyk9497]

I have 2 TV's over 10 years old I set at 60-80% still going and never had a problem. I just trash picked a 4 year old Samsung 50" from an old lady neighbor of mine that had a bad backlight diode. Just fixed it real cheap. Reak nice clean TV. One thing I noticed is the 2 Samsung's that I have, both 2018 TVs, one is a 50" UHD 4K and the other a 50" 5 series, both default the backlight brightness to 100%. So if you don't know to check it you'll be getting a new TV or a repair in a few years. (2-4).

Aw common just fix it already. 😀 You couldn't replace it for 20 bucks but if you don't need another TV them just scrap it for parts. As far as content it's still digital and it did end up in the basement so all good stuff. Thanks for bringing us more diverse videos!

[@jimlayer2403]

I actually repaired this same set for my neighbor. One of the led strips was bad. Went to harbor freight and purchased a cheap pair of glass removal suction cups for about $6 to safely remove the led panel as not to bend it. It is very thin and will break easily. Ordered the pair of led strips for about $25 and replaced them. That was all that was wrong with the tv. Neighbor was happy. Only charged him for the parts.

[@suadcokljat1045]

I say fix it but on a component level (replace only dead LEDs). That could be fun and interesting. Give yourself a budget, say 4-5$ total. Waiting for part 2...

[@arongooch]

As he mentions, the aluminium backing is essentially a giant heatsink. Ive tried this before and even flooding with lots of heat it's very very difficult to remove the LED's from the strip. You would also want to source the correct matching LED's because different types will draw different currents and have different voltage drops across them. This could possibly confuse the controller or might end up with different brightness LED's etc. Having said that, I personally would fix the set. $20 isn't too bad.

[@changhsieh459]

Ye had a vidao brand tv that have shadows because they have leds with different brightness.

[@lionnelc13]

@@arongooch yes, soldering this leds strips can be a pain in the ass but it's possible. First i remove the glue from the strip (burned glue really stinks) and place the strip on a piece of steel that allows me to heat it from the back using a small blowtorch, without burning the led strip. I also keep every led strip i can find (from broken lcd) for spares

[@arongooch]

@@lionnelc13 That certainly sounds the way to do it.

[@joselu90]

EXCELLENT video.... you spoke clearly, you explained what you were doing, the camera work WAS PERFECT (focus, lighting, etc), you intelligently cut out the boring parts (removal of screws, etc) and what you did keep was helpful to someone still finding their way around inside one of these. Thanks!!!

[@flamespear86]

Interesting video that gives a lot of insight into how modern TVs and led panels work. You can see how these things are designed to be modular and repair usually just involves replacement of larger, but still relatively cheap components. Also, seeing how these are made compared to the price the markup on them seems like it's pretty huge.

[@Dutch3DMaster]

They are modular, yes, but that's due to the nature of how these panels work. They are not made to be repaired: manufacturers do not like to hand out information on what to look for when troubleshooting them down at part-level. For regular consumers, those relatively cheap components are usually hard to get, and some brands actively discourage consumers from being able to replace parts by not making them available to them, and sometimes have a price-point that is deliberately designed to put people off from buying the replacement part to sway them to buy a new set...

[@ModernDIYProjects]

Fixing it to keep it going is the best way since it saves garbage from landfills and helps others to learn from your content. That's the way I do it. Also, $20 is a cheap fix, but if you want to be even cheaper, look for another similar TV that gets thrown out and use that one for spare parts. I always keep my eyes open for good condition stuff that people throw out, to use as spare parts.

[@olafwagner]

I agree - fix it. It is worth way more as a functioning display than the sum of its parts.

[@soilmanted]

@Scott Lichtsinn You can get a new one for less than $100 with new features and comtemporary methods of connectivity - ability to play video files on flash drive, function as computer monitor, etcetera. I don't think it would be so easy to sell it for $50. I recently bought a 19 inch monitor for $5.00. It doesn't have a TV receiver built in, so a display with a tv receiver would be worth maybe a little more than $5, say $10. Only thing wrong with it: 2 or 3 pixels don't function. Is it LED backlit or CRC tubes, I don't know.

[@soilmanted]

@Scott Lichtsinn I live in Asheville NC and I bought my $5.00 19 inch diagonal monitor here. 16 inches by 10 inches. It is 1440 x 900 pixels. I'm using it now so I can look up the model number easily. Branded "Envision." Model G918w1. I think it was manufactured around 2008 or so. I seem to recall being able to download the owners manual. I bought it at not-for-profit second-hand shop. Before buying it I was allowed to plug it in to a 120vac outlet to see if the "no signal" legend came on the screen, but not allowed to plug a signal into it to see if the signal got carried all the way through. I knew at least that the backlight was working and some of the pixels were functioning. So I was taking a small risk with my $5. The not for profit company claims that people donate their used stuff to them, they sell the stuff to other people and they use the revenue from those sales to operate a no-kill animal shelter. Yes I was surprised it was only $5. I think Goodwill and Salvation Army are selling similar ones for $20 or $25 leading me to believe I might find one at a yard sale for around $10. I have picked up 2 other flat-screen monitors for free. One from a friend who bought a newer, bigger one, and one from an estate sale.

[@therugburnz]

If I can't get it working I save a few choice parts like the leads on the ribbons The boards and Fresnel lenses diffuser etc.

[@DuhBiggestDog]

@@soilmanted All the new PCs, even the SBC type have HDMI out. And, seeing it is a 32" Samsung, it probably is at least 720P. I have one that is 1080P that I use as a monitor on my Win 10 desktop. Also the HDMI out means you get the benefit of stereo quality sound for normal PC functions. For $20 it's worth it.

Found the led strip on Ebay but shipped from China. Looked around and found a supplier in Austin Tx...of all places. For me it was worth the repair and the TV plays just fine, as good as new. After some thought, I think these LED's are sensitive to power surge. Interestingly, everything in my bedroom media cabinet was behind the UPS except the TV...go figure! Your situation...I wouldn't repair unless it was in pristine condition...You can pickup a 32" at Walmart under $100 bucks...its just whatever floats your boat.

I had this exact experience 2 months ago with a trashpicked Samsung TV that I think looked exactly like this one, even the additional screws for the stand.

[@thulinp]

A warning about power supply current limiting. There's a capacitor across the line after the limiter. This means the LED will get far more current for a split second. You need to be aware of this. The capacitor value can be pretty high in some supplies.

[@tiporari]

Ive fixed roadside trash TV's before. It's fun. Any TV with no local dimming will have 1 or two series arrays of LEDs. Driver circuit failures are common and easy to repair. The whole boards are also readily available.

There are a number of products on eBay but really no good way for consumers to know what they're getting (and they're not cheap) because amazingly there are no retro computing channels that will bother to take the time to survey these things and review their efficacy and value proposition. This channel, given the technical expertise, is probably the most qualified to actually do such a survey.

I have been doing this type of repairs for about 20 odd years now, those Samsung TVs are notorious for an smd resistor on the T-Con board shorting open and pulling high. Might want to check that.

I replaced the LEDs on a 32" tv, sold it on ebay and broke even (25UKP). I wouldn't bother doing it again but it's good to know that at least one device has been saved from the landfill.

[@greengrayradio1394]

Your power supply surely has a capacitor across its output (you see the LEDs flash very brightly at first) This might kill them with the high current

[@Mustakari]

A good quality lab power supply has very little capacitance at its output.

[@wemingle]

This is what I thought as well.

[@ferndog1461]

Thanks for video. I've repaired 3 flat monitors, so far. Donated a rescued Samsung 22" to a jr high school. I have fixed TVs by swapping old capacitors with new ones or swapping boards. The label outside the TV will not, necessarily, identity the particular boards inside. So before you order parts you need to take the LCD apart & record the part numbers on the boards, theirselves, power supply & the main board. Then Google the board part numbers for " kits " of the needed capacitors & resisters to renew your TV. There is a thriving DIY supplier community on the web that will sell you a kit for your particular board. If you have basic soldering tools, you can solder the new parts in. Samsungs commonly fail due to $ 3 worth of capacitors failing. Thank you for your work. Peace.

What I have done in the past with things like this is I search on ebay for the parts for the model of TV and see what items are commonly sold. You'd have seen the LED strips and that would have been a big clue what the problem was. On my Toshiba it is a chip that burns out on the mainboard and for $65.00 I bought one that was refurbished. Solved the issue.

[@benedictrehiesi5166]

Fix it by replacing the dead LEDs, it's a common type failure that I've seen a lot and I really would like to find a trick to repair these cheaper.

[@KEVINSEPTEMBER]

My Samsung stopped working and I noticed the red power light (power button on the bottom of TV) is blinking a code. Just google the code.

[@TampaTec]

Great video 👍I fixed few LED TVs with same issue, even though LED should last a long time kinda doesn't because people like bright backlight causing early failure. If customers turn off the lights in the room and keep the backlight to 50% it'll help prolong the backlights. Just my logical guess why it fails.

[@joselu90]

Yeah thats what I say to people keep the brigness low and your leds will not burn.

I found a 23" LCD in my bins one night! It would show the standby light but do nothing more! I opened it up, took a look at the power board and found a swollen Electrolytic Capacitor! I replaced it and it worked perfectly! A friend of mine did lots of image work but only on a pathetic 10" monitor. So I gave it to her! I wasn't interested in money, her joy on receiving it was worth way more! I have to say though; LED.s in Series? a recipe for disaster.

A friend of mine gave me his broken 50 inch Toshiba. It was only 4 years old but off warranty already. After carefully opening it up, I replaced the LED strips (turns out I only needed one) with a kit I got online shipped to me for about $120. Best $120 50 inch TV I bought ;)

[@KaosZ007]

or just buy a brand new one for 199

[@the_kombinator]

@@KaosZ007 Yeah? What brand? Also, how will that help me to learn how to fix something I never got my hands into? Sometimes saving only a little (or outright purchasing spares for more than the book value of what's being fixed) is beneficial in other ways than just the perceived value. The difference here is consumerism vs. tinkering. I would not otherwise buy a 50 inch TV because I use it like, 2 hrs a week, mostly to play Wii with my family. The plasma 42 inch I as a result gave to my dad would have just kept being used by me. The end result is that the TV did not end up in the trash piles in Africa, getting open-fire burned for the traces of precious metals within. My whole channel is about repairing old stuff and selling it. Simply purchasing a new TV would not add value to what I do for fun :P

[@my2centz196]

Usually if it's the leds they will flash but I've never seen one that didn't have a bunch of strips and a few of the leds on some of the strips will go bad so this is a first to me but I've never bothered to repair a small TV. Only reason I know this is because at least the ones I've repaired has had that issue. I'm no professional by far so I am constantly learning new things and this has definitely taught me something. I have learned my lesson on repairing leds though lol. The first few times I replaced just the blown leds and not long after a few more blew. I also had an issue with the first 2 that the globes would fall off and caused spots in and had to take back apart again to fix. Regular superglue doesn't seem to hold them very well lol. I do find it fun to repair them and maybe I'll repair smaller ones now I've watched your video and I'm glad I did because I'd probably just replaced the boards thinking because it didn't flash that leds where fine. Good video thanks. Oh you can replace the leds with either a heat gun or a heating iron. They're actually really easy to replace but I suggest the heating iron which I can't remember name. The strips themselves actually take heat well and it doesn't seem to effect them. You can buy hundreds of leds really cheap but make sure they match. Also I'd use 2 part epoxy for globes and be very careful to place exactly in the correct position because they matter lol. Anyway good luck. I'd like to see you fix it myself.

[@adventureoflinkmk2]

I had the exact same problem with a 32” soniq TV, I had broken the lcd panel of another TV a week b4 so I recovered LEDs from it to replace the dead ones. I used a hot air rework station to swap out the LEDs. I then melted the defusers back on and followed up with a little super glue. I would say try fix it but, try do it for free. See if you can get an led TV for free with a smashed panel, you can swap the LEDs or retrofit the led strips from it. You can probably ask around on Facebook and get one :)

[@edwardlandrath7113]

I think you should fix it.

[@jbinary82]

I fixed my HP monitor also just by soldering an aerial connector. It's funny the mess when opening these slim panels. I also fixed a Logitech mouse by resoldering the cables. And my xbox L/R buttons replaced by new push buttons. Simple things that make us proud.

[@crx1stgen25]

This is like replacing old school Christmas light bulbs, trying to figure out which one is faulting the circuit; except way more complicated and involved.

[@RayMerrell68]

With LEDs in grow lights, they fail closed. They stop working then because they pull more current from the constant current power supply which then trips out. It means all the others will be suspect because of the extra heating they went through. Some may go pretty soon after you replace the dead ones, but they themselves can be replaced until it works. At the end of the day, they're just white LEDs, you can always bodge a solution with LED strips.

[@DonaldPerkins]

Use your own LED strips and wire them in directly to the power supply. Just bypass the built in controller. EDIT: If you still want brightness control you can always connect a potentiometer and mount it on the case somewhere. It would be fine as a spare TV for the lab at least.

[@charlesgallegos3575]

Those TVs are great for using as a monitor, those old LCD Samsungs haven't almost any lag on game mode.

[@SianaGearz]

How about a ghetto fix? 7 12V flexible LED tape sections in series. 450mA drive per LED strip, means it will support 20 or so parallel LEDs at full brightness, give or take. The screen is 70cm across, the rear of the lightbox smaller than that, so at 30LED/m it will take about 36 LEDs per width, 12 3-LED sections in parallel with LEDs spaced about every 3.3cm apart. For each series section, you stack two or more strips in parallel vertically. 2*7=14 for 40cm screen height, so about 1 LED every 2cm in height. 36*14/30=16.8m of LED tape. Or maybe just 6-series instead of 7 then it's just 14.4m. You can probably just remove that white reflector sheet that sits around the original LEDs near the rear of the lightbox. Don't know about painting the metal rear of the lightbox white, but that's an option anyway, probably not super necessary.

[@stuartofblyth]

I'd want to know whether the LED supply voltage is high because the LEDs are dead and therefore its not under load, or whether the LED supply voltage is high because of a fault and it KILLED the LEDs.

[@Windscar267]

Hi I’m actually a tv repair person and there is a few tips I can give you yes order the strips that’s a great deal. The defuser for the led light I suggest you wear gloves when handling that cause you can get fingerprints on that and can be seen on the screen. There are two points at the connecter of the led to test them all at once. The power board sometimes has a problem with the ic but when I saw it it looked good and no problems that I see from you video. I suggest you download the latest firmware from Samsung it will be the same firmware for your tv. One more thing you can light the backlight just by disconnecting the mainboard from the power board the backlight will turn on immediately. I hope this helps you I hope to see a update on this tv

Interesting, just did a repair video on a similar TV with similar issues. Looks like the LEDs in these TVs have a tendency to go bad, and when they do, if you're lucky they go in a closed state. Bought a little heater from ebay to make replacing the individual LEDs a bit easier. Hot air seemed to work also, but more of a pain. You've made it that far, I'd just fix it.

I've got a similar model that went dead on me a few years ago UN39FH5000FXZA. Same thing as yours with no picture but good audio. I figured it was the backlights, the 39" has 3 strips so runs in the $50 range for all 3. If I were to repair it I'd just replace them all especially with all the failures you saw. You replace the bad LEDs you could just stress out the old ones or if they were cheap LEDs they may just burn out on you at some point down the road. Mine is still in the basement and I'm not willing to fix it. I had to replace the T-Con board shortly after getting the TV since it was cheaper to buy the board than shipping back for a return. It was a manufacturer refurb unit so lesson learned on that

[@KB1UIF]

I have the 40" smart version of this TV and I did like you and got it from a recycle center with no back light. I had the same problem of various LEDs failed, after much research online I found a suitable LED to replace those with based on Voltage, Size, White light type and surface mounting polarity. These LEDs are available from various sellers on ebay and aliexpress for pennys, you can get 100 for about $5 or so including shipping from china. Beware tho that just because it says for Samsung they may not be suitable Voltage/polarity wise etc. The problem is replacing them as you noticed they are mounted on aluminum. What you have to do is heat each from behind with a hotplate. I got a special little tool from shop jimmy to do it that's basically a hotplate but small in size. Ive seen people use other methods like a small gas torch. If you watch my series of videos you can see I fixed the same problem kzbin.info/www/bejne/p56aiWt3f6aDoKc. A tip, replace the panels with the TV face up that's how it would have been assembled and goes back together easy. Good luck.

Bit concerned about your power supply arrangement and whether you in fact destroyed all but one of the LEDs. Find it hard to believe that you connected your supply, saw them flicker then die and it didn't ring alarm bells.

[@toyz66]

You are right , these LEDs seem very sensitive and the output capacitor of a bench supply can hold enough charge to kill them before the Over-current kicks in. A series resistor is needed. Also these LEDs don't like reverse polarity (unlike normal LEDs) there is a bypass diode which will go short circuit if probing around if you are unsure of polarity, again series resistor is all that is needed to save it.

Fix it or keep for spare parts. Reduce or Delay, your E-waste. If you keep it, I would recommend keeping a log of parts replaced, record it and any Part numbers of modules that you can replace. Keep the log or copy inside the case or the back. you will not need to search for it later if something else happens. depending on price you maybe able to buy some spares in group packs , new replacement clips should be cheap. you have two units and after this work you may want to fix another one.

If you don't want to spend any money on it, or you need it running ASAP you can also remove broken LED, and solder it's + and - terminal. That will OFC be harmful for other LED's, and reduce their lifespan, but it was broken anyway's. Keep in mind that in the place of removed LED picture will be slightly darker, but in normal conditions this is barely noticable. Same "fix" is possible with LED lightbulbs. I had TV with missing 4 out of 20 LED's, and it was working great for next 4 years when i replaced it with newer model.

[@kthwkr]

Use a pancake griddle. Heated to about 350F. Put the PCB you want to solder on it and let it get heated. Using a hot air soldering tool, heat the LED you wish to remove. Since the temp is already elevated, just a little hot air will melt the solder on that LED. Use tweezers to pick up the LED. The white plastic case of the LED is not high temperature plastic and will likely melt into a blob unless you are able to move very fast. It is rare you can take this type of LED off and then put it back on functional. Instead of a hot air soldering tool you can use two soldering irons with wide tips going at it from both sides. LEDs should pop right off. The hardest thing about this technique is avoiding burning your wrists on the edge of the pancake griddle as you work.

Samsung support is funny, at least in my opinion. I bought a TV that developed a problem with the backlight flickering occasionally. First it took several calls to get them to admit that I had a problem. They demanded photographs of the test pictures which naturally didn't show anything of the actual problem at it was backlight flicker and even that was kind of random. After a few calls they sent a technician. He was very professional and easy to talk to and he managed to provoke the backlight to flicker by lowering the light. Apparently it was some problem with the light control when the intensity was to low. Screw it up and everything looked alright. Well now that he knew what the problem was he would have to order the spare parts and come back in a couple of days to repair the TV. Well a couple of days later he was back with a big honking carry box. So he strips down the TV to the bones, and replaces every single thing except the bezel and back where the sticker with the serial number is located. Then he updated the service records for the TV to show the serial numbers of new parts. So effectively as far as Samsung is concerned I still have the same TV with the same serial number, but every single component including the LCD panel, the back light, the power supply, the TV module and every thing else, except the front bezel, the back bezel and the speakers has been replaced. Now what I find weird is that they didn't just send out a complete TV as replacement. Now they had to pay a technician to do two trips to my home, spend a good amount of time to disassemble and reassemble the TV crawling around on his knees on the floor. Taking a TV apart and putting it back together means there is a risk that something will be damaged which would make it even more expensive, and finally this technician had to spend time entering the serial numbers of the components he swapped in. To me that seemed inefficient and expensive, but at least they did fix the TV.

Most of the issues with these are the firmware. mine definitely quit due to a firmware update - the firmware update samsung gave out broke soooo many TVs.

Always a gamble fixing LCD panels with backlight as I've done quite a few LG iMac LCD panels in the past, and you do have a small percentage/chance of cracking the LCD panel as they are so thin and fragile. Usually you can see this though after v. close inspection. So if you're confident it is fine then I would say go for it, for and replace the backlights (assuming they are correct voltage and light output)! Also like you say you have spares!
