I don't know about any common issues with Whitestar per say but a trouble spot on that particular board is the magnet board that controls the satellite and ball save (between the flippers) magnet. Also optos can be flaky sometimes. My DMD would go out and after opening the speaker panel and wiggling wires would come back on. The problem was the connector on the top corner of the DMD controller board, that is mounted right behind the DMD, had fatigued pins and were not making good connection. After replacing the connector, it worked great. This is a 3 pin connector with a black and red wire and the middle pin is not used. Congrats on the great find! I really like my GE.

Check the fuse on the display power board (3/4ASB.)
Check and reseat the connectors on the display controller board behind the DMD.
When you first turn the game on the DMD should flash briefly with the version number of the display software (probably 4.00.) If it doesn't do this and the fuse is good, try a different DMD in the machine.

Common Whitestar problem is battery leakage taking out the RAM and/or ROM and possibly more depending upon how long it's been in there. If the display flashes briefly and goes out and the machine does not go into attract mode, the CPU is not booting. Bad RAM/ROM/traces by the battery/any and all of the above need to be investigated/remedied.

Good luck - hope you got it for a really good price. Replacement W/S boards are not cheap.

Definitely a great price. When dialed in, this is a surprisingly fun game. I am still really enjoying mine.

Damn super jealous been looking for one of these for a year now.
