My game is driving me nuts. It seems to be from what I would call a half of a rolling screen. The game plays scores, sounds and attempts to display correctly but it's not right. I can read it enough because I know the game, I have rebuilt the power supply with Action pinball's KIT-DE-HV4. Still with the same result. My voltages at the P1 connector, I have my 5, 12 and 68 volts. The only thing that I have a question at what points do I test for the -110 and -98 voltages? I have tried several sources and if I use the ground on the connector I get -65 for the -110 and -3 for the -90. Where do I put my meter lead for a good reading or was I correct? I also have my 5 volts at CN2. I have unplugged and plugged back in all cables and ribbons and nothing improves or changes. I have switched the rom out, no change. No cold solder joints from what I can see and have tested all the power traces on the board. I would like to either comfirm or rule out a DMD before springing for that. The best way to describe it, it seems to be rolling, about the lower quarter of the dmd seems to be duplicating what would be the regular readout. It almost appears as a mirror looking image with it rolling rapidly. Any help would be appreciated, thanks to you all.
