BA troubleshooting
Posted: Mon Jul 02, 2007 7:13 am
Hey all--I was going to post this at The Lab but can't seem to get into my account there.
I just built the BA4, and three channels work perfectly. Channel 3 is dead though. Here's the weird thing that happened...when I tested each, I got silence from 3...until I flipped the phase. Then I could hear a weak signal. I took out the board, checked all my solder points, resoldered everything, and rechecked the I/O and power connections. Put it back in, powered up--now it was totally dead, and even the phase trick didn't work.
Any idea what might be wrong, where to look, or how to test it?
