If I restart in Diagnostic Mode the error is ThermalProtB.
If I start in Protect Bypass mode the unit runs flawless until next power up then will go back into Thermal Protect since the anomaly has not been corrected.
If I measure the Thermal Detect B line coming from the Amp it measures identical to the Thermal Detect A line (about 1v). This makes me think the problem is not in the amp but in the way the B detect is handled.
I can't tell if the cpu is looking for active low or active high to shut the unit down. I'm attaching the SM, schematics and a screenie of the pin designations of the cpu.
Any pointers definitely appreciated here.
