Hello

I have a beomaster 6000 on the workbench, it wasn’t working at all when it first came in but after replacing the motor belt, all the caps, a few resistors, the bulbs, and reflowing all the solder joints on the connectors it turns on and plays fine. I set up the reset after replacing the trimmer resistor as stated in the manual (the voltage was not very stable but stayed around the recommended 2.3v (swings from 3.1 to 1.5v). I also replaced the trimmers on the power amplifier and adjusted bias and offset and the trimmer on the power supply for the 6.5v supply. Now it turns on normally, everything works but after a certain lapse of time it switches to standby (somewhere between 5 and 20 minutes). I tried disconnecting the fault switch trigger coming from the power amp (without speakers in case there is indeed a fault there) but it still turns off after a while. I tried moving the connectors and gently pushing on the circuits around the processor to see if I could recreate the fault but nothing triggered it, it just happens after a while.

Any help would be very welcome at this point.
