Bob;
For starters....this set uses the famous PIP module...99% of your
problems are coming from there...Remove the module and bypass the
input/output with the 2 caps..
If you don't have the repair procedure for the PIP, let me know and I'll
send it to you.

> When this set was left, customer said set picture would scramble and go
dead in an hour or 2 days.. We hooked up and set worked fine for like 2
hours.. Then, we lost sound and screen went dark... turning up screen we
found we had no vertical sweep.. We replaced scan diode {checked ok} 26v
supply thought it feeds vert/audio. We did have B+ on audio chip and vert
output chip when set was not working.. Today went to work on this set, has
sound, grey screen and scrambled out of sync pix.. removing bottom shield
found found glue had damaged trace near jungle chip, repaired and the same,
scrambled pix. Probably another supply voltage missing..But without a print
its very hard to trace and there is no sams listed..Hope someone has some
ideas..
