Went ahead and dismantled it today, got down to the main board and couldn't see any visual issues. Caps all look perfect, as does each PCB. Cleaned everything off

Does anyone see anything I'm missing?...

Recently got this set for $15.

When plugged in, the power light turns red as normal,

and when powered on, the backlight immediately turns on, as does the blue power LED, but there's no other indication of startup; the input indicator sometimes shows up, but sometimes it doesn't.
