Another Troublesome Machine.

This time it’s an A4000. This one was sold to the owner with full notice of bad sound and previous battery damage. I managed to replace both audio amps, and then only had sound on one side working. In the end it was a bad VIA. It just shows you that checking one pin to pin isn’t always going to work! When you send things in and it takes me longer than expected, this sort of thing is a big cause.
