Wow this is the most extensive video that covers tv failures - amazing

Thank you for this guide! By far the most thorough and thought out. I'll be doing some testing on mine this weekend.

So yup, backlight failure got me too. Dnag. Well, ti lasted me abut 8 years so I really can't complain. On to a new one. Thanks for the great troubleshoot and explanation video.

Thank you so much! Lifesaver took the back off, cleaned all the connections re-hooked them all TVs running great

I followed your instructions using a flash light test. You are correct. I was able to see the images faintly.

Thank you so much, i have a roku tcl 55", and there was no picture but the backlight was still on, the warranty was expired so i cracked the back panel open and messed with the t-con cables prior to the video and got the same result you talked about, on this tv the main board and t-con are combined so ill look into buying a new one. 👍

I bought i new main board and installed it and after couple of days it started with the same issues again. Has this happened to you to?

Thank you so much for this video!!! I was able to diagnose and order a power board for my 2-year old TCL, which was showing a black screen, but I could hear sound and see a faint picture when putting a light to the screen. After a very easy installation of the power board, my TV now works, and I'm so glad to be able to fix it myself and not have to get a new TV / contribute to e-waste.

@@katherinestevenson8848 I took the back panel off of the TV, unclipped the ribbon cables (mine had two attached from the main board/t-con to the power board), unscrewed the power board, put the new one in and screwed it in and then reattached the two cables. It was extremely easy - I don't have any prior experience installing any electronic components.

I've had my TCL for 6 years. I don't expect more. Just died tonight.

Do you have any ide how to turn off screen,but sound on(youtube off screen mode),and back to screen on again wtihout restart the smart tv safely.... Like putting any switch in certain position...

I have a 2021 TCL and backlight just stopped working. Following these steps I can’t figure it out as mine does not have a Tcon board and when I unplug the connector from power board to main board it won’t allow me to turn the tv on to check if the back lights will come on 😢. When it’s all plugged in and I first turn it on the backlights instantly flash on for a split second but nothing more after than. Really hate to replace with it not even being 3 years old yet. HELP ME!

Thank you for this video. After I tried your suggestion of reconnecting all the wires inside the problem an old Samsung had only gotten worse. I don't blame you, but reconnecting all the wires inside does not always help fixing the issue, it can also make it worse. I did see a connector where some arching must have occurred on high voltage pins, I think for the backlight. I might try to solder the wires to the pins directly if I feel like it and if that is doable. Wish me luck.

@@techtests I have fixed the television! At least, for a while. I took five wires, two of which had signs of arching, out of the nylon casing and connected them almost one by one, and then hot glued them onto the board. I tried to make sure that the wire was connected as good as possible and then solidified the connection with the glue. After five wires I just dabbed the whole blob in more blob and hoped that the connections were solid enough. And behold, after 3 minutes of warm up time where the issues were still the same, the image came back! I do not dare to turn the TV off now, as long as it works. Just to keep the circuits alive and make them feel good again.

@@sldkjh idk how to fix mine :(

So if the flashlight test reveals faint images, and none of the component tests totally fixes it, you need to move on to a backlight test?

I literally had a TCL Roku TV for 7 months and it failed. First time I've had a tv fail.

My menus work and I just watched a video but when I play a video from its apps (Disney, hbo, prime) the video is black with no sound. Menus and overlays all work as expected. WTH

I reset my tv by pressing the home button 5 times and then the up button then rewind twice and fast forward twice and it made my tv turn on but then after a few seconds it started to fade to black starting with the right side and slowly moved to the left. Is that still a backlight failure?

What if I have a backlight and the remote light is on and I can hear sound but I can’t see anything. Model 65s446

When i plug in my TCL the screen barely flashes up for a split second them goes back out, few seconds later flashes on & off again then nothing but sound.

Thanks for this great video. After pressing the reset button I now get a message that says press the home button to turn on the screen. Pressing the home button does nothing. Does that indicate anything? I did the flash light test and can't see any images. I haven't taken the back cover off but after reading you website sounds like the main board.

mine too as its attached to a notebook, but the pic returns should as i change the channel, refresh the browser, or power on/off. this never happens with utube, peacock or any other channel, it only happens on utube tv. so the issue is,if any of the options recommended applied to ALL displays where im watching including the cable, motherboard or power, then that would be easy to troubleshot. the board, cables or power would present this issue regardless of whether im watching peacock, roku, utube, motherboard or regular tv and it does not...so im a bit stumped.

I think they program them to just stop working after a certain time. Mine is a 55 inch five years old, but barely used I get sound but no picture. Programmed Obsolete, so I hope it was worth the scam, cause they won't ever get my money again.

Hi sir,I have Xiaomi A2. My child spray water. So suddenly now no display. But have sound and back light. Can water damage can be repair?

If I have both cables connected to tcon I see the backlight flicker at TV boot but never ultimately lights up. I did flashlight test and there is picture with no backlight. If I remove 1 of the 2 lvds cables from the panel it flickers 2x at boot on 1 half of the screen (opposite of the side of the plugged in lvds cable) and if I swap which lvds cable is plugged in the 2x flicker happens in the other half of the screen... I have sound and I'm guessing the tcon is the issue?? Great video btw!

It's difficult to say for sure, but if you do have a picture with the flashlight test, then I would say the T-Con is ok, and it's most likely a failing connection/bulb in the backlights. I would test the backlight strips before replacing anything. You can use a couple of batteries and a pieces of wire to make a circuit if you don't have a multimeter and check each LED individually, and check the connections between them.

Yep. 6 months here. Lol going LG next time.

Hello ! I replayed a few times this video might as well ask. I have sound on my tv. I tried the flaslight test but I cannot see any image. When TV is on I can see a "glow" and if I press left or right in the controller I can see the apps moving very very faintly but no image whatsoever its just the glow from the background lights that do the motion and I can see it. Following from your video this means I got a T-Con board damaged? cause if I had backlight failure screen would be plain black or if main board is damage I shouldn't get audio correct? My though is that I have a bad t-board but just wanted to confirm here first before getting one from ebay. Much appreciated !

@techtests

I would think that it's most likely the T-Con, but it could still be the main board or the connection between the two. I would open the TV up and try cleaning and reseating all the cables first, before ordering anything.

5 years is pretty good for modern TVs to be honest. They're built with cheap components to lower the price, rather than being built to last.

I'll never buy Another TCL TV IDC if it's 90 inch for 500 with Roku . I'm done with them ....

Who the fuck is unscrewing their tv, might as well buy a new one
