Not sure but I would check the Commodore section on the VCF.
There are many diagnostic episodes there.

Hi,
I recently picked up a PET 2001-8. It has a video issue...see
http://imgur.com/PKc97 (disregard the black diagonal scan lines...digital
camera artifact).
I seem to remember reading something about a similar issue, but Google is
not returning anything. Does anyone have any leads or ideas?
Thanks,
Win
