A3000 Pixel Jitter

Electrolitic caps have a limited lifespan. Any originals on your board are now ~20 years old and could be part of your problem. Same goes for the power supply. Weak caps or drifting power supply could be at the root of the problem.

Let us know how any repairs/cleaning go.. I've had a lot of a3000 in for repair or resale that have had this problem.

I've cured several over the years based on the info above, including 2 of my own. Pretty common video problem in many arcade cabinets I've done also.
