Maybe a bad amp? Or maybe a ground loop. Apparently a ground loop will do that kind of situation but everything I’ve read about it is discussed as AC purposes, not DC. I hope you can figure it out
Thanks for the input.i do notice what looks like a voltage regulator on the pcb (red), but i cant read what type it is..
it also appears to have a buck converter setup to the left of that? (yellow)
its pretty hard to tell from this image, but i would start probing around those areas.
I did get to this point before taking a break and I supplied 5v to the leg but didn't remove the IC, no wonder it didn't work.The 8 legged IC circled in yellow will have one leg that outputs ~5v. If you find which leg, you can remove the IC and supply 5v straight to that pad.
Cheers.Awesome casework! I do not have the patience to sand that much. GG
