Well, got another broken TV due to overconfidence I suspect, alas this one is another dud like the other TV I have that seems to have a bad tcon (not worth to buy another)...
Anyway as received the backlight is out. Okay, but the power supply looks good, got a solid 24V out to the backlight. So I tried feeding in voltage into the backlight enable...still no light. Boo. Probably bad inverter or bad tubes.
Okay...so that sucks, now the other half: the mainboard. Again PSU seems to get the right voltages out so rule that out. Can't see anything in screen with a bright light and the mainboard doesn't detect when the backlight inverter is disconnected (no error code)... so I think the mainboard is also dead. Also couldn't seem to get sound out of the TV as I randomly pressed buttons on the remote. The only button that seems to do something is the power button.
So...looks like I got a rock here, better luck next time, apparent double failure is just not a good omen, perhaps it was a parts unit peddled out as a leftover parts unit or something *sigh* if only I could tell if the panel is any good, probably can't until the backlight is up, chances are the panel is also bad.
Risky risky...disposal is the unfortunate cost.
