Power Problem

Qix has been making me crazy. The video has waves in it after a few minutes of powering up. Now I find it freezes or dies completely afte a few hours. I have tried everything in the Qix cabinet. Swapping parts with the Klax to eliminate failure points. I am stumped.

The last remaining failure point is the power supply itself. It is a newer switching power supply which should probably never fail, but I will swap it out with the power supply in the Pole Position to test it.

Qix is now working beautifully. It was the power supply all along. Great, Pole Position has only the origianl power supply. I assume it is not working and that's why the previous owner installed the newer switching power supply.
