Hi there, I have a rather interesting looking set of boards in this Wasabi Mango U400UHD TV (korean OEM), not much information available online.
The components inside appear to be a mismatch of OEMs - the power board comes up as an RCA part? The TCON has Samsung logos on it, and there are no real identifiers on the mainboard, which I think is a generic part?
Either way, I'm not getting any indication of life now, aside from the power LED changing colors and the startup chime. The shutoff chime seems to be gone, although the LED does change from blue to red when shutting down. I was able to get it working for a period of time previously by jiggling some cables (not sure which it was, it just magically started afterwards), but have no such luck now.
I didn't find any obvious test points or things to check on these boards - any pointers for what I should try to diagnose?
