I bought a non-working Wizard of Wor a couple of weeks ago that was DOA. I rebuilt the 90411 power supply with a Bob Roberts kit and now the game will boot, however I've got some graphics glitches on the game. The game is fully playable, but I'm wondering if this is an indication of bad RAM, game ROMS, or power. After rebuilding the power supply I'm able to adjust the +12 & -5 voltages, but the +5 is stuck at 4.85V no matter how I adjust the pot. I attempted to use the test switch to get into the diagnostics menu to check the RAM / ROMS, but all it will do is display the rug pattern below. Any ideas?
