I have a U5000 that just started losing sync. It began a couple of days ago. When I would first turn the game on it would look like this.....
After a couple of minutes it would straighten out and be clear. It would work fine until I turned it off and when I turned it on it would look like this again. Now it does not clear up and constantly produces this piciture. The screen is not rolling. It looks like a common sync problem created by the wrong input wiring, but that is not the case. I even redid the sync wires coming from the harness and nothing changed. The behavior of clearing up after it gets warm the first couple of times makes me think cold solder joint so I am fixing to take the chassis off and reflow it. Any suggestions on areas I should pay particularly close attention to? Thanks in advance.
