Re: Dot Matrix "Ghosting" Effect?

http://www.marvin3m.com/fix.htm Go to Clay's great site, get your This Old
Pinball stuff there ( best bang for your buck in the hobby ) check out the
wpc repair guide, dot matrix stuff, study up on heat issues - you may have a
simple fix like heat sink compound. Or you may not, but it will guide you
through testing and repairs. LTG :)

On my TZ I recently got in, I noticed after the game has been on for a
few minutes, the display starts "ghosting" images, as if a fluttering
cloud is around everything. It's especially prevalent in the display
test when you scan the vertical line across the display. It almost
looks like flames surrounding things on the screen. What causes this? I
don't believe it's a ribbon cable problem, seeing as it doesn't do it
at first but does once it heats up a little, and it gets worse the
longer it's on for. The display also displays visible vertical
"scanning lines" like you might see on a computer monitor or tv... what
would cause this? It's got me confused. Might my display be going out?
The display looks great with very minimal burn-in. Any thoughts or
experiences with this phenomenon?
