Have you tried swapping the X and Y parts to see if the signal problem moves to the other side?

I haven't had a chance to do any work on this yet.

Okay, I pulled the board out to take a look at
When you say swap the X and Y parts, are you referring to the DAC chips?
Some people have said check the DAC chips, others have said swapping out the AVG chip fixed the issue with their setup.
I'm not great a soldering, so I'm not sure I want to swap those chips unless I have to. Should I replace the AVG chip first with a new one as a starting point?
Damn, fixing the cabinets is easy. This stuff is driving me nuts and takes the fun out of it!
Kevin Mullins:
The quickest and easiest thing to do would be to just swap the AVG chips and see if the problem moves. (since it appears they are socketed)

The AVG chip is socketed, but there is only 1
Level42:
There's only 1 AVG chip, 2 DACs.
Clearly directly soldered. Not recommended to try to get them out if you're not good at soldering. You can do a compare measurement. Run the board and measure each pin on both DACs. See if there are some really off values between the same pins.
