Factory reset. I'm sure you have tried. Did you see if the TV has the correct main board? Maybe someone tried to repair with wrong boards -
In the service you need to change the LVDS format from JEIDA to VESA or from VESA to JEIDA.
or change 8bit to 10bit or 10bit to 8bit.

Hello again. This time it's a TCL 50S425 Roku TV that is stuck in a boot loop.
The TV will power on, display the TCL logo for a few moments, and then the TV restarts in an endless loop. It sounds to me like corrupt firmware.
So far, I have:
1. Disconnected the power cable and pressed and held the power button down for 30 seconds and tried powering on again - No change.
2. Pressed and held the RESET button for up to 60 seconds. - No change.
3. Tried disconnecting power cable in the middle of one of it's loops,... -

I Have a 75" TCL 8K Roku TV (75R648) that I think has a bad T-CON or LED board.
The TV powers on and has audio, but the screen is grey and cloudy or has digital noise.
I can navigate the menu, but obviously, I can't see what I'm actually doing.
Tried power cycle w/ no results.
Without pulling out the multimeter and testing the individual boards, any ideas about what is going on here?

I have a TCL Roku 55S403TCAA. It quit working after a storm. Other electronics quit working as well so I am pretty sure the storm had something to do with it. Anyway, I took a look at it, no obvious damage, blown components, scorch marks, etc. I am looking at the power board first, 40-L141H4-PWG1CG. I've repaired bad caps and blown components but nothing more extensive beyond that. I am trying to troubleshoot it, but I can't even find the fuse on this board. There are markings on the PCB saying "replace fuse as marking" however. I attached a photo of the board. I am also testing the...
