LG 65' LED - 2160p - Smart - 4K Ultra HD TV
Model: 65UH6030
SKU: 5622526

Just turned our PS5 off where everything was fine. Approx 60 seconds later the TV screen lost its default home wallpaper, went to black, and started flashing this white light from the bottom (see video).

Controls are unresponsive.

Bottom power light flashes red too.

I reset the power, still having this issue. The TV's a decade old but has otherwise been great. Is this its death?

I used a water-soap-vinegar solution while trying to clean this grimy silicon grout I used a solution that had vinegar. I quickly wiped it off but this small area is rougher and has lost its shine.

I'm already kicking myself. Is there some way I can refinish or reseal this myself since it's all white? I really don't have the budget to hire a professional. We could only afford this in the first place because of insurance replacing a moldy sink.
