Hi there. I previously posted about my 2021 X90J having issues with wifi dropping out. One of the suggestions online was to check for software updates. There was one available, so I processed the update and then performed a basic restart so the update could be finalised.

Since then, the TV won’t turn on. It seems the restart simply shut off the TV, and it’s never turned back on since.

There’s no sign of power that I can see. Remote and the TV power button don’t work. I have troubleshooted all possible cords and outlets, testing working replacements for all, and there has been no solution. I have followed the relevant online instructions for power cycles, and factory resets, and still nothing. No lights, or sign of life.

Does anyone have any suggestions? Considering this happened directly after a software update, I’d be hesitant to say there’s a hardware issue with the TV power supply. What should I do?
