Woot my vanguard is fix now pictures on last post

I pick this up last night for free and the cabinet is not that bad of shape. They said they moved it from one side of the garage to the other and that is when the problems started. The graphic problems are when you shot the ships they leave behind blocks on screen, colors are wrong such as the background is white and not black. So where should I start on this.

I'd start by re-seating any socketed chips like ROMs and such. Sometimes all it takes is a gentle pressing in of the chips if they have just worked loose a bit.

Woot my vanguard is fix thanks to a board I got off ebay. Board may have been untested and it was dead but the chips was good after a few chip swaps it was running in right colors :)
