Help with general tso’s

[blainehawes]

New-ish builder here. So I’m building general tso’s compressor and the led would stay on when the switch was on and off. Fixed that somehow, but no sound comes through and the leds for the ldrs don’t seem lit. I sprayed some iso-alcohol to take the residue off the board and now the led doesn’t light and nothing seems to work like it did before. Any suggestions?

Sounds like you probably have some cold solder joints/solder bridges going on. I’d first look at cleaning up the solder joints. Any loose wire hanging out etc.

The leds arent supposed to stay on, they turn on when enough voltage (signal) hits them to turn them on.

In addition to the cold joints, there seem to be a number of potential shorts on the solder side.

Update- reheated all the solder joints, but still no sound or power led lighting up. Is it possible that I fried the circuit? I ordered another pcb just in case.

Naaa, youv’e barely touched the troubleshooting spectrum. Take voltage readings and build an audio probe.
