EASY LED LCD TV FIX - no picture black screen backlight repair kit

[@vivekanandamurthy7255]

Hi have a LG smart TV model number 50 LN5750 , i am having the back light issue , can you tell where can i find the compatible back light strip

[@jrose92081]

I did the same thing to an LG 42LN5300 last night. I ended up doing all the leds and lenses for fear of future failure for my customer. Just a few things to add to this great video: When reinstalling the diffuser lenses make sure you get all the old pieces out of there. If the diffuser lenses are too high off the LED it will create weird circular spots on the back light panel (layers under the lcd panel) that will be visible while watching TV.. i found that out the hard way and had to lower about half of the lenses. Also avoid prolonged heat or too much glue as it will discolor the led itself causing the panel to have inconsistent lighting...Great video!

[@TampaTec]

good tips

[@jrose92081]

Tampatec Thanks man, awhile back i was talking to you about a sony kdl-46hx800 with I think a five light blink that pointed me to the LED driver. I replaced it checked back lights, checked everything else. I found a service manual as well. Service manual said to replace the main board and if that didn't work the lcd panel was bad. I found a fuse the size of a grain of sand (1 of 20+ fuses) on the T con board that had a cold solder joint.. I just used my hot air station to heat the whole board up popped it back in and it worked! It was a 2010 TV that quit working in 2011 and sat till 2016. I actually obtained the TV for service in 2015 and after the T con board replacement failed to fix it the customer told me to go ahead and keep it because he did not want to spend anymore money on it ..It was an awesome feeling to bring back that TV..

[@TampaTec]

Jess Rose good job! you seem like you been doing TV repair for awhile. Yeah those Sony TVs can be bad tcon boards or bad LCD panels or buffer boards hard wired to the panels. So far techs in China factories are doing the LCD panel connection repairs. I posted it on g+ but no one use that anymore.

Thanks for the video I have a TV that have back like problem and I have be trying to fix it when I turn on the TV the light will on for about 2 seconds and goes off

[@awuntiemmanuel2124]

Good morning. Your program are so interesting,I love it. How can have ur repair kits

[@tommathews1200]

Just a simple question. Are Hisense TVs worth repairing? One I'm working on has screen rubber taped to frame.

[@TampaTec]

Yes, if tv is less than 5 years old it's worth fixing. How long tape fix last?

[@briancraven840]

2 thumbs up now just got attempt this. My Sharp Roku lc-50lb481c suddenly went dark. I did what you said with the LED light to see if anything is on in the background and sure enough it's working so hopefully this is the problem.

[@redpillcommando]

I saw a jar of Radio Shack Flux. This warms my heart and breaks it at the same time. I miss Radio Shack.

[@TheFusedplug]

My Toshiba is a heavy and thick width TV but it's going strong. I took your advice and set the backlight lower but I've taken a gamble and set it to "Auto" as that seems to keep the backlight around the medium mark anyway (maybe you can shed some info on "auto" setting? thanks)

[@pastoraseniam.escalera6725]

It was an interesting video thanks for sharing. I have a Phillips LCD TV that shows a little bit picture. When I turn on it takes time for the picture to come up and then it is dark in the left side. Please give some advice about what I should do. Thanks.

Hello! I have a Lg model # 37ld340h. It just all of a sudden went to a black screen, still heard the volume then just completely stop doing anything. Could you please tell me what younthink it could be?

[@robknapton156]

How do you determine what model of led you need for the strip? Is there anyway to tell prior to disassembly? Or do you need to see the led to tell? I have a Vizio M70-F3 if that helps

[@ANGELSURS]

Just search online your model and replace the led strips. They are cheap $

[@nimalp100]

The lesson is truly helpful to a beginner like me. Pls can you advise me what I should do to sort out the problem with sounds on a LCD TV. The picture is ok but the sound is not clear. It gives just some rattling sound. How can this be repaired? Do you recommend to replace the entire motherboard? The model is SLD3218CV Singer. Thanks, Tampatec!

[@bob55today]

The LED Back-light strips are LB50068, but what is the part number for the LED that is soldered on to the strip for the VIZIO E50x-E1 ?

[@sumraizbutt3243]

Hi m8 will you please confirm me every tv have different backlight led or we can use any led strip for any tv i mean to say if i m change only led point

[@TampaTec]

Yeah, unfortunately they are not universal.

[@sumraizbutt3243]

Thanks m8 i m really enjoyed ur video keep it up

[@Triezowa]

will I be able to use these LED strips on my UE50F6400 series TV it also is 3D capable. I am stuck on what LED lights to use and ive tried searching for them but can't find them anywhere I don't know if I am searching for it wrong, please I need some help it would be much apreciated thank you

[@efrainrios238]

I have a 55" LED, but mine goes dark intermittently, works fine. Sometimes it goes out qite few times but trning it off and back on restores the picture. Sometime it does this anywhere from every few seconds to a few minutes to the ooint the=at after going trhu this cycle for a while it remains bright with a couple of dark spots in the back ground, one in lower left corner other on right aabout two thirds down from the top.. Could this be due to the led failure ot=r just the backlightinh module??

[@MusicMinisterJP7]

Interesting work procedure. I like that those LEDs can be replaced, however, in my opinion, depending on how old the LED strip is, I'm more prone towards replacing All the strips, to be on the safe side, of not having to go back in a month or two later, for the same reason, having had the opportunity. All the same, it is good inspiring technological work. I am currently about to replace the strips on my Samsung UN55J6200DAf..

[@asheryupano4895]

Hi good day my devant TV yesterday shut off the picture but have sound what can I do to fix it. Thank you I hope you can help me for my problem

[@twins56]

Great video Question for you,i have a Samsung UN46EH5000FXZA series udo3 and i has 44 led's and got 20 that are burnt out. I already bought the work station and led strip tester,Where do i get the led's to solder in that will fit the strips.

[@tammygosnell]

Quick question.If the first LED is bad on the strips,then the whole strip will be dead right?Your tester still lit up the good ones and showed you the bad ones in the circuit.I tried 9 volts in a series and it didn't light up anything.I thougth these were wired liked Christmas lights.?1 out none works?

[@lincolntewhaiti6404]

Hi I have a Veon 55 ' 4k Ultra HD LED LCD tv.Model V55UHDS. I have no picture and no sound. I plug it in and get a red standby light.I then power on the tv and get a blue power on light.But on the screen theres no picture and also no audio. The screen stays on for 1 minute and 19 seconds then back to the red standby light.Any help would be appreciated.I dont have/own a multimetre to test it. Thanks.

[@dalemart]

Hi Tampatec we have a LG tv model number 37lk450u-zh the problem we have had is we recently moved to France from the UK and the tv was in storage before our arrival, I believe that it may have been damp in storage as there was condensation on the screen when we unpacked it, So when we plugged it in and turned it on it went pop which feel may have been a fuse on the circuit board maybe you could advise, I have attempted to click on you link for parts but this does not work which may be to do with the district we are in.

[@hopefaith4313]

[@godfreyarcher5764]

Hi Tampatec Thanks for your help with your Videos .I have a Sharp LC-80LE632U that has worked for three and a half years and presently it's not working and I would like some assistance to fix it. I am getting a Blink 1S+1F code and the backlight is not coming on I have done some troubleshooting and the present state is :- [1] I am getting a Menu in the background with the Remote. [2] I have tested all the 15 LED strips with the Backlight tester ("They are thirty LED 'S in series") and the voltage of the tester moves from 315 to 175 volts and with a current meter in series I got 29.1 mA of current flowing through each strip. [3] I have tested two new Rows outside the TV and got the same 175 volts and 29.1 mA current. [4]Row one just like in the TV with three segments P/N:5073+5069+5071 all in series comprising of thirty LED's. [5] Row two ,, ,, ,, ,, ,, P/N:5072+5070+5024 all in series comprising of thirty LED's. For the fifteen Rows in the TV they have alternated Rows one and two. [6] I have just finished changing the Backlight driver IR2E67M after doing some Internet training and practicing on some Motherboard chips . After installing the chip I notice the whole Menu with the Backlight flickering a little and lasted for a around five seconds and if I disconnect the AC plug the TV would resort to 1-1 Blink code . [7] I rechecked the TV after cleaning and testing the Power Supply connectors with CRC and got a stable Menu. I was able to reset the TV using the Menu and started an auto tuning which got dim after finding about 14 channels. so.I am planning to re check the other Backlight components on the board and do a re-flow of all the soldering joints to see if I could improve on the present state of the board.I have also noticed that the Power Supply Diagram is not available in the Service Manuals for the 60 to 80 inch Sharp TV.

[@hkkim4365]

Will these kits work on Toshiba side lit TV's like the 46L5200U1? The LEDs are longer and only on the right side of the set in one long strip. Shop Jimmy has a replacement strip 2012SGS46 for $49.95 but no individual LEDs I could find.

[@叮叮铛铛爸]

Dear Tampatec, I have a 50PA4500-UM from LG. It has sound but black screen. The remote works fine. So I can turn it on/standby and change the volume. I noticed when TV is on the power LED light at left-below of screen has no colour light. And when it is standby the light shows red. I used LED flashlight to check the screen when I press setting button. Nothing shows just black screen. BTW: when I press any button, the power light flash as red. So I removed the back cover of TV and check back light. It's all black and no more other light except two red lights on the EAX64696607 board. Could you please tell me what's the next step should I move? Thanks a lot and have a great weekend.

[@danielmichaud2909]

Hey Tampatec, I was wondering if you could help me figure out what's wrong with my led TV. I thought it didn't have a picture, but when I tried the flashlight test there actually was a picture, just very dim. So I figured that it was leds going out. I have 3 strips, the bottom one never comes on when testing it. The top one and more than half of the middle one lights when I test one led in the middle row. I'm using a digital multimeter that I bought from Walmart. I was just wondering what settings you put yours on. Thanks in advance.

[@OriginalMergatroid]

It looks like Shop Jimmy is not answering the comments (not that I can blame them). That's too bad because I have a question as well. I have found a TV that keeps blowing backlights. I have replaced three LEDs so far and I bet it will blow another one. It's a Haier HA2347 55" curved TV. I have the service manual and the voltage to the backlights is within specs. I can only assume there is an issue in the power supply that is intermittent, or something wrong with the power in the house. Does anyone have any other suggestions?

[@andreallridge1695]

Thanks for a great video. Can I use a hot air soldering station (no heat gun) instead of the backlight strip work station used in the video? If so, at what temperature? I didn't find the backlight work station for a reasonable price (I'm not in the US, so a) shipment costs exceed the price of the device itself and b) the power plug won't work for me).

[@DavidB-rx3km]

Yes! You can get the tester for £10/$15 dollars, don't pay $60 for one that is identical but has a ShopJimmy sticker on! Also the LED Rework Station is just a soldering station with a sticker added and price doubled.

[@richard3422]

@Tampatec, can the small fuse at the base of the strips be replaced as well? I replaced an LED but the fuse was grey instead of black

Hi Paul, thanks so much for all the help. I have the shopjimmy LED tester and the rework station here, but unfortunately shopjimmy won't have compatible LED's for my Vizio E65-E3, so I'm going to have to go with another online vendor. Problem is, I'll have to find LED's that will match up. Good news: I found compatible 6V LED's with the right dimensions and anode/cathode solder points for my strips, and I successfully soldered and tested a couple of them so far. Bad news: I can't get a matching color. I've sampled up to 6500K Color Temp but none of the new ones I've tried are as far on the blue side of white as the existing (or the ones we see in your video). I'm starting to give up on finding a good color temp match. Do you think I should just use the new 6500K LED's and replace ALL of them even though the native LED color won't be the same? Maybe the TV color settings will be able to compensate? Have you ever been faced with this?

It varies depending on the size of the TV. Larger TVs (55") can use 350V. I have no idea the wattage. It would depend on how many lights there are.

Can you use a hot air station and solder paste instead of the plate?

[@omgffsification]

Wouldnt a variable power supply do just as good a job as that led tester unit? And a simple hot air gun do for the soldering job?

omgffsification never tried maybe

even some batteries in series would do the job of a power supply to test the strips.

[@jeffescortlx]

Yes, a lab bench power supply would work, but you would have to be careful to not exceed the led rating. I normally keep it under 100 ma and it's generally safe. Any higher and you risk blowing good leds.

[@aloud9738]

Peter Enis am wondering if the battery from the hoverboard can they are 36v

[@gt50inc]

Are you from Tampa? Do u have local location?

[@scottmaurier5638]

Can I test the backlight WITHOUT taking everything apart?? I took the back off to the boards, do I have to keep going JUST TO TEST??

[@OriginalMergatroid]

You need a backlight tester. The lights are usually set up in series, like an old Christmas tree, if one LED goes out, they all go out. You need a 300V + backlight tester to connect to the backlight connector to see if they work. Or, you can measure the power on the plug for the backlights with a volt meter. If it is good power (at least 250V, but I've seen up to 350V) then there is likely at lease one bad backlight. Now, you have to decide of you want to remove and test the strips for individual LED replacement or if you just want to replace all the strips. If this is too confusing, or you can't accomplish it without someone's help, you should really take it into a TV shop if there is one near by that will do backlights.
