Tampatec hey Tampa I have tv when I turn on tv there's sound but no picture when I put a flashlight on screen you can see it

[@miseryinc.7523]

Tampatec hey, I have a LG led 48" smart TV. Approximately a little over two years old. Tv works but I get "snow" on every input. Even screen cast. What happened to it.? Thanks for the great videos. Tv is otherwise snow. Not the cable box, or HDMI cable. Have picture on menus just not in any inputs. Thanks

[@leokersting7999]

Tampatec I have a Vizio 55" 4k tv model number M55-C2 the serial number starts with LWZQSBBS The mean board is bad and looked for a replacement one but no luck only found other one's that aren't compatible. I was wondering if I replaced all the guts would that work? Or does it all come down to the panel that would not be compatible?

[@SwapPartLLC]

Those boards are identical except for firmware. So the replacement was programmed for a TV with a different LCD panel. You could have swapped the eeprom from your original board to the replacement and it would have worked, I do it all the time.

[@TampaTec]

SwapPart TV Repair yes, that saves some money, if u want to link your video here, I'll give you a shout-out. 👍

[@scottreilly4397]

Great videos! I just returned my Vizio 43" into service after a lightning strike. Thought it was the power board because I had nothing. I replaced the board before watching your video on checking voltage on board, that would have saved time and money. Bought a mother board on E-Bay, the correct number but wrong series, more time and money wasted. Well, after watching another one of your videos I got the right one. Last, everything worked but the remote control. Ordered an IR board, no go. With time and a lot of patience I checked the little 5 wire ribbon cable to the IR board. That was it! All fixed. I'm no electronics tech, just a retired guy with a Fluke meter. The parts total was about $70.00, It would have been less than half that had I watched your repair videos first. Thank you, I still saved $300.00 on a new TV and had a lot of fun fixing the damaged one.

[@maehay4065]

You are so honest to share your mistakes with us as well as your successes too! This was a very informative video. Thank you for sharing this as I certainly try to learn more about electronics! 👍👍👍👍👍

[@just.observer4648]

An excellent simple tutorial. You seems like a decent man! Definitely not an arrogant. Keep up good work.

[@Fardeenfarwest]

Hi tamptec. Awesome 😀. What I appreciate with you is that you really explain steps by steps and how to figure out the problem. Even if you make a mistake you don't hide anything. You truely shows us what the main problem and how it cause. I really appreciate your videos. 👍👍👍👍👍.

[@TampaTec]

Thanks Fardeen farwest I appreciate that.

[@rva]

You have a smart mind! Insightful video.😊

[@manuelrodassotelo791]

One more video wich shows you are honest enought to acept mistakes made and share with the rest of people. Learning from mistakes is not the best way to learn but defintinely once you make one will not forget Thanks

[@brettito]

Learning from mistakes is the only way to learn.

[@honyr.8788]

You are correct bro, for us technicians we can learn from our mistake, important is we learn a lesson from it then avoid not to repeat it again, never considered our self as an expert, don't be over confident to avoid unexpected mistake.

[@JimN5QL]

Fantastic informative video! I'm from the old school of tubes and point-to-point wiring. Before I found your Channel I thought LED TVs were throwaways if they went sour. Please keep making videos like this!

[@TampaTec]

thanks

[@ricksaniti7588]

Man Tampatec guy! After watching a lot of your repair videos, I feel like roaming the streets to find junked TV's to attempt to repair. Great stuff! Really great stuff!

[@secondwindmusicproductions]

The number stamped on the board is for the raw, unpopulated board. The same board is often used in many applications and may have both different devices mounted on it and different firmware. That is why you need to use the sticker number.

[@vernroach3413]

This is the second video I have watched from this gent and I learned from both of them...A talented instructor.

[@chaplainbrucecardwell7507]

Thank you so much for sharing your knowledge. Thanks to you I was able to fix my 48 “ Phillips for $4.50. The cost of 2 capacitors from a local electronics shop

[@MausMasher54]

Good info, I was given a dead Sceptre 32", it works thru the PS to screen with a bit of the old snow storm effect, only button that functions is the on/off and standby LLED, so now I will try your solution and see if it works once more..TYVM...

[@100bl]

Great informative videos... got some great information when my 46’ lcd Toshiba had no picture , found out was bad inverter ( blown capacitors) ... that was last year & still working 👍

We learn more from our mistakes than we do from when we get things right first time. Great training video and an invaluable lesson for all electronics aficionados. Thank you!

[@meganwatchorn6468]

Thanks, man. What's the best way to determine if my TV's LED backlights are burnt out? My screen is completely black - no flicker, no gray bars, and failed the flashlight test (I think I did this right). There is no sound and I cannot pull up the main menu. LG LED TV Model# 50LB6300-US 1. Red stand-by light (solid and flashing, but not sure which is which) 2. No Sound 3. Tried all the troubleshooting methods (including reset, unplug for 60 seconds, changed outlets, changed remote batteries, attempted to change sources, etc) Is the next step to order a new motherboard? Thanks for your videos. I learn so much from you!

[@emkameindert]

Hi Tampatec, Are you open for questions? Your vids encouraged me to get a broken tv and try to fix that. Initially repair of lensbulbs fallen of and also a bad Tcon (probably) My first goal was to fix the lensbulb, so I glued every single bulb. After I re assembled the the the screen had 1 vertical stripe right at the center of the screen. It wasn’t there before. The screen is not cracked! I have a photo taken as an example might you want to see it. I looks like a whole vertical straight stripe of dead pixels. Do you know what the problem could be. I also ordered a “new” Tcon board with the same numbers on the board but a different sticker, right before watching this video. You allready guessed it, it doesn’t work. ;-)

[@clivegreenwood4003]

Thank you for putting this info out there, I'm in the UK and have had a few TVs from the refuge centre with a view to getting experience in fixing them and thanks to you I have repaired 4 out of 5 and given them to family and friends... you rock man.

[@orlandojohnson5742]

Thx 4 D video! I'm used to giving numbers to supply house & them sending parts(HVAC!)! Sometimes I give all the numbers I see on the board!! Or they ask for more numbers!? Online can be different than direct consultation before getting part confirmed correctly! That's not really your fault , it's a live & learn moment of online expectancy!? Usually the model & serial number of the product & determining the part would be enough!!!? Version of the board... the company should know what parts are in the unit from those numbers!! But no... they want the tv service man to have it easier than the actual owner!? Thank goodness some of these electronic companies are really trying to help & get the right part to customers!!

[@nancyaltimus6794]

Love watching your videos. Your teaching skills rock! Maybe one day I'll open my tv w no pictures to troubleshoot it! Thank you.

[@kirkdalton3195]

Just had to say Thank you! I followed your guidance, ordered the right part, and fixed what was thought to be a dead tv.

[@waynemightymetalworksndoth4788]

Very nice I've a JVC smart TV no standby light but the fuse is alright

[@rlwings]

Good video! - What about HDR LCDs? - Can the back light be set higher than 50% to achieve the intended brightness levels of HDR? - Are the LED strips designed to handle more brightness on a HDR set?

[@CarlosOrtiz-ht6rn]

Very informative video! I think I need to replace an older lcd tv that will not power on. Thank you for showing how to order the correct board.

I love it you put the mistake you did in this video. It makes me feel better when I make mistakes like this. LOL This video helped me a lot in fixing a Sanyo model DP42D23. Thanks

[@nimalp100]

Excellent teacher. So helpful for beginners like me. My LCD TV has unclear sounds. Sounds rattling and not clear. The pictures are good. Is it a problem with the sound amplifier? When the sound is coupled to an external amp, then the sounds are clear. But internal amp must be defective. Can you pls advise me how to resolve this problem? Thanks.

[@olivercrosby1535]

This stands true for laptop motherboards as well. The main printed number will get you a board that looks the same but there’s normally other revisions and some revisions cause issues.

[@raymondferguson1935]

Great video I wonder could you give me some advice I have a e-motion TV the red light is on but with the remote it will not switch on it will intermittently turn on with the button on the side of the TV any help would be very much appreciated thanks

Hi. I have to say these videos are very helpful soo Thanks. I have however a question. I accidently cracked the light diffuser panel while removing it. Its a crack of about 4-5 cm (im not sure how many inches is that). But the question is are you going to see the crack in the the end or is there a way to fix it or should i just start looking for a new one

Bro your an honest guy. You get 5 stars from me.

[@williamlane7493]

Thanks for all of your great videos. I have fixed several TVs with your help. I have a Sceptre x505BV that had intermittent power issues. More often than not, it would not turn on. I replaced the power board, but it still won't turn on (no lights including the standby light). Is there another board that controls the on/off or should I be testing wires?

great video. i use your contentt as refrence material a lot this year . this is my first time seing this one though. i replaced my power board but the high pitch sound still happens. i see here that you swapped the main board to get that high pitch sound out. so can you explain more about what causes the high pitch noise>? is there any wauy to get rid of that without swapping the main board? i have image thats fine (though i need to get into the service menu anytime it reboots in order to set the boundaries correctly)

[@lostprophet6042]

Are the boards keyed to the screen or just configured a certain way I'm just curious how the exact same board and components didn't work

[@josephantony5589]

Truly very honest demo

[@Hortor]

Of course it's luck, but sometimes, logic boards can be changed... even with other models TV from the same brands !! What I did that works in Samsung (2008-2010) : - Logic board from LE32A466 to LE40A456 (same inputs, so same back cover) - Logic board and Power board from le32C450 to le32A466 screen, T-con and inverter board - Logic board from le32b450 to le40a456 (just one "SCART" "PERITEL" port missing, but works) ( Power board from le40a456 to le40a650 : PROBLEM with inverter not working, the power board differs from a letter and a connexion is missing) I'm sure there are a lot of posssibilities to swap boards with others models, at your own risk of course !

[@ChristopherNealBUSHIDO49ERS]

Paul, I have a Samsung UN55UH7250F 55” curved TV. It has developed a shadow in the top half of the screen. I can still view it but the top is noticeably darker than the bottom half.

Was told replacing the T con board might take care of the problem. No luck, still have the lines on the right side the screen, any help would be appreciated. Hate to replace the TV, it is only seven years old with minimum usage. Thanks.

[@SinnSabs]

Only today I saw your Video and I was amaze. Because I have a problem with my tv too and I want to fix it. My friend I need your help regarding Sony brand. I will just ask you which part of the board does this code blink 3 times that must be replaced?

[@nimalperera5454]

Its a 32" LCD TV. Not working. 5V shows on one of the sockets of the power board where 5V is printed. But on the other socket where 24 V printed, nothing is shown to the multi meter. Checked it by removing it from the main board. The middle legs of the bridge rectifier 230 V is shown, but + and - legs shows no power. Do you think the bridge rectifier is defective? Grateful for help.

Very useful video as well as some others you have. Been trying to diagnose the following problem with my Vizio M557-G0. Powers on fine, get video and sound fine...BUT left 1/3 of screen will fade to gray (still able to barely see video playing) then come to brightness and can see entire video on screen, then repeat about every 5-6 seconds. Right 2/3 of screen stay crisp and clear. Found some bad capacitors on the main board and replaced. Problem persists. Switched ribbon cables to backlights - left to right right to left, problem persists. Voltage on t-con board reads ok. Is it a power board issue or could a section of backlights be faulty? Thanks for any insights. Brian

Hello boss! Not sure if you still making videos, but I have a 55 inch LG TV and it stopped working after a power surge, I checked the power supply board and I get the 3.5v going to the logic board but no 12v, does it still a chance that the logic board is bad?

[@falcon2077]

Hi, I'm hoping to get an answer from you. My LG TV was making the same noise, blank screen and no volume. I changed the power board, the main board and the wires. It still didn't work. Could it be the the LED light are broken? would it still make that sound if it was the LED lights? Thanks

[@journeyon1983]

Did you ever check the old board to see what was causing that high pitch sound? Being a tech, it's always challenging to find the answer to everything. If you did that, then you'd have the option of ordering a replacement board or a replacement electronic part.

Hi, i have a question. If I have a Sony tv that has a cracked screen in the corner from being hit with a drum stick that went flying across a room by accident, but has no visible crack when tv is off, do you think i would be able to fix it my self by replacing one of the panels that you talk about?

It's crazy how many revisions they make of these tv boards that look identical. The timing of this is good since I was looking for a board replacement there that was not in stock and was considering a desperate attempt to order one of the other identical looking revisions to now realize that I am very likely SOL I wonder if and how much Samsung costs to replace these parts since 2.5 years lifespan for a $2800 TV is BS!

Thanks for your Video. My TV is TCL U49P6006X1 49 Inch. no picture, no sound, no faint picture (tried with flashlight in dark room), only the T-Con lights when I turn on the TV, and when I press any button on the remote control, the TV turns off again, with a quick flash on the screen that I have seen just in a dark room, that shows a text, I recorded that as a video, and was able to read the text, it is saying "3 seconds to power off volume" that text is not really helpful. So I'm still confused, whether it is one of the blacklight stripes need to be replaced (as other youtube videos have suggested), or the Main Board as you have described in your video. Any help will be appreciated.

[@berryelectronics]

I've had several of these. I trace the short on the main boards and find that there is usually a surface mounted capacitor that will short out. Replacing the shorted cap will repair this.
