1977 Zenith 9" rolling problem

A warning about Sams. For the $22 you will get a crappy
PDF or Xerox. Sometimes unreadable & you have to reorder.
Try to find the original printing, its very high quality.
If you dont find a free bee here contact me. I probably have
it & can sell it.

It looks like the sync pulse comes out of pin number 15 of IC chip IC401. If the horizontal is working, I would go to cap C601. The other caps on that chip can also affect sync, if that is the hold problem you are having.

Thanks so much for all this information, I knew this was the place to go.

You have tried the rest & we are the BEST.

No it came from the old TV shop. We were a Zenith / Admiral dealer. One day an old Italian couple came in for a new set. They had real thick accents.
Asked the usual questions & when brand came up he said " nothing but a Zeno !!" IIRC they bought a console with a mediteranian
cabinet.

Thank you, that makes total sense.
