View Full Version : MS8 with dark diagonal lines, slowly scrolling?

Hey all... picture on this MS8 looks excellent (itís in my Pony Mark III with 25Ē crt)

However... one last issue is some slowly moving/scrolling diagonal lines. Any thoughts? Itís hard to get a pic, but hereís a closeup. The photo makes it look darker than it is in person, but gets the point across.

The chassis ground has continuity to the main ground, but the wire is SOOO thin. I added another, thicker wire to a chassis screw and hooked it into the main ground on the PSU. It helped a little?

Got it!! Wired from chassis metal screw to PSU ground and from cabinet body to PSU ground. Lines gone!
