I would like to add an update to this.

I purchased Sams schematics, and through the helpful hints they provided for
things to look for I found that a transistor on the PIP module was bad Q7001
(2SA933SRD).

Because of the symptoms, I was on the right track with the PIP module being
the culprit, but without prints and a scope I would not have been able to
fix this.

Thanks to all that helped.
