 Hey everyone again,   I have checked the LA4270 Amplifier IC on the Audio
Out PCB.  I have 30 volts comming into the La4270 on the VCC pin.  The
inputsare reading about 100 mV and the outputs are reading about 50 mV.  I
checked the speakers they are fine.  All the wiring and traces are fine.  I
am thinking about replacing the LA4270 Amp IC.  Any other ideas?  Thanks.  
Mike
