Dark vertical stripes between color bars?

Ditto the PS in the Sencore, I had a similar issue with mine, except the fold would stabilize at the top of the raster and I would have a 60 cycle hum bar that seemed to be more pronounced like a 120hz cycle. I popped the unit open and repaired multiple cold solder connections. This suprised the heck outta me because these older Sencored are built like a tank!
