You guys are amazing! I realize I didn't give you much to go on..
Grant in this case it isn't the physical alignment of the buttons. The problem persists with module fully free and out of the case.
I don't know if the previous owner preferred coke or pepsi but these "ivories" have been soaking in it!
Bo, I'm checking out the upgrade. Looks pretty sweet. the good news is that I actually have the PG 200 module. This is a great and useful link. thank you!
Dennis, my money is on the IC. that "feels" right. I had a sony r7 that had needed IC replacement, as well as a pioneer sx-580 stereo..My first DIY repair success story!
I'll keep you guys posted. thanks for the excellent help!
