Solution, buy a new TV. My 55" TCL Roku has been doing this now everyday… it's worse in the morning, circuits are temperamental when it comes to the extremes. Unfortunately, unplugging it every 5 to 15 minutes gets monotonous after doing it 20 times in a row. My TV is only 5 years old. Perhaps it's time to get a different brand and pay the extra expenses upfront for something that will last.

I had exactly the same problem. I found a temp fix for it at the moment, but it is not an ideal solution.

Anyways, I believe the problem is caused by 1 or more faulty LEDs in the back. I believe this somehow alters the voltage and it somehow triggers a safety mechanism to turn the LEDS off(since they are working at start). I figured that lowering brightness might lower the voltage on the LEDs and that it would not trigger the safety mechanism. I put it on the darkest settings(I turned on the T.V in a pitch black room to be able to see the settings). I turned it back on and it was working. However, it sometimes still triggers what I assume to be a safety mechanism of some sort every once in a while. I just turn the T.V off and on and it should work. If it does not work, then just unplug and redo it.

I know this is not a good fix, but at least it allowed me to watch a Star trek episode on it.

This was the only thing that worked for me! The screen was VERY dark but not completely gone so I turned off all the lights and I was able to get to settings and put on the darker mode. Thanks so much for posting this!!,

This helped my TCL to work again but not always. For a more permanent fix would it be the LED light strips or the power board that I would need to replace??

@tapan when this “and then screen blacks out. “ happens, in a darkened room, shine a flashlight at an angle against the screen. Check to see if you can make out shapes, silhouettes etc. TCL has issues with backlight failing. If you can make out silhouettes it is most likely the backlight array that has failed. If not, you will have to remove the back cover and check the power board. Measure the outputs to the main board as well as to the backlight LED’s. Let us know what voltages you get. Post some good pictures with your question so the we can see what you see and follow your troubleshooting to help you out further.

I have the same problem. How do you jump out the safety circuit to get to test it. I use to be an electrical engineer

Can you send me a pic so I know?

Changing the brightness setting to darker helped fix my issue but not always. For a more permanent fix would it be the LED light strips or the power board that I would need to replace?? What usually makes the LED light strips trip out?

- de

@paolodeu application of to high a voltage/amperage when they are already weak or a weak spot on the solder connections etc.

SO if this happnes then you are basically screwed forever?

@Jair Reategui no, not really. All you would have to do is to replace the LED backlight strips.
