Check all around IC201 or whatever loc. the signal processor is on that set.
Check for peanut butter(adhesive) and scrape clean. I had one of those for
vertical collapse and found a run had been cut clean from that stuff
hardening.

> 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..
