I found a 4yo tv by the trash - I understand why. When i try to power on, it lights up for less than a second, then immediately goes black. I've tried a factory reset/power cycle; no dice. The logo appears very dimly and can be seen with a flashlight on boot. So my idiot question: does anything in the boards look suspicious, or is it the LED backlights? It's $40 for a new power supply board, $40 for new backlights, and totally free to just throw it back from whence it came, but I'd really rather not (e)waste it if I can give it new life. Obviously swapping the board is way easier than the leds, but the led work may be over my time/patience limit. Fwiw its a 2023/4 Insignia ns-55f301na22 - would appreciate insight/advice!

Given the current state of things, though I'm not at all mad about buying these things cheaply about 3 years back, I'm wondering if they're overkill for my setup? I used revad's script to create an nvme storage pool on a 1520+, and then dumped my Plex install on to it. Definitely don't use even half the capacity, just bought them on a whim with room to expand!
