I just want a sanity check here...
Got this TV that has funny noises from the Y sustain board, no picture and no sound. Other than a dimly lit black background, it's dead. I don't even get a standby light. The optical audio terminal doesn't have a red light either, which I find odd.
Vs and Va are happy and I have 5.2 and 17V to the mainboard as well.
If I short the test pattern pads on the panel LVDS interface board and plug the set in, I get some pretty test patterns. Funny noises from Y sustain cease when the patterns are playing, it gives only a very faint hum.
This does indeed confirm the main signal input/processor board is faulty correct?
