Troubleshooting my Star Wars. Currently no errors (that I can tell) in test mode. Game plays but in both test and game play the image is stacked on top of itself. Using the game and monitor pots I can barely get the image big enough. Spit killer on, but image still displays.

It seems like the up and down pot movement is limited, the left and right is better but I get more expansion to the right than I do the left. Makes me think I still have something going on in the XY section of the board along with an issue causing the image to stack.

Some background: working Amp monitor (tested with another game), board was working (had early VL ESB kit) and then played blind. Removed kit and restored PCB to original. Had issue in XY section that I fixed to get board to display again. Had, "Bad Mathbox Ready line." Swapped out the Proms with the VL prom board and I'm where I'm at now.

The test modes look the same with original PROMS vs the VL PROMS. I don't recall what the game play (if any) looks like with original PROMS…I'll have to look.
