I have replaced the output ic (U31) but I still have nothing. All else works fine. I have tried to trace down the audio path, but the print is really a joke. I have Vcc on the 2 inputs from an outline of the IC (TDA8946AJ). I have nothing on the scope at the L/R inputs, but I can touch the inputs using the old wet-finger method, and I get a hum, so it seems that the IC is working. .....one thought, though; there is a regulator Q27 that reads:
I=11.58V
o=12.2V
Adj.=12.2V
I need to work on my crossing/ subbing skills, but I can't find this part number anywhere on the net. The number on this reg. is C5886. If anyone could help, it would be appreciated. I just can't seem to get anywhere with this one. I know the voltages on this regulator are not right, but I don't know how to proceed with the toilet-paper schematics from Vizio.
Also, I know some of these used a separate power supply for the audio, but this one doesn't have a stand-alone smps unless someone b4 me has really got me and good!
