Cap'd a K4600 and now video issues: Zaxxon.<Resolved>

Coming to the guru's. I'm at a loss on this one. Did a full cap kit on this 4600 monitor. Hooked it up this weekend, and now there's a weird video issue going on. The high score and text screens look perfect but any screen with gameplay looks very odd. Played with the black level pot and saw that it got a bit better at times (could see the full ship and walls), so ended up replacing that pot but still the same results. BTW Blk lvl POT is in the full on position. Is this an adjustment issue or something else? Any insight anyone can provide would be great.

You guys rock! Went through and reseated all socketed chips, and reflowed some of the main header pins. Back in business.
