I recently bought a crazy Climber machine. When I went to pick it up, It was working but the screen was slightly glitchy like there was some interference or something. When I got the cabinet home. I used a test LCD screen I had and the game looked identical on the new screen. I spent some time cleaning the inside of the cabinet with a light bar inside and fixing some questionable wiring the PO had done when he installed a new switching power supply some time ago. Now when I turn on the cabinet I notice Im missing certain sprites and some of the colors get goofed up. I since have put it a new power supply with the same issue and verified power at the board to be correct. I'm thinking one of the rom chips or another chip may have been erased, corrupted, or damaged somehow. My best guess is that the light bar inside the cabinet could have done this, as it was glitchy when I bought it so I probably added to it. I know there are 13 chips on the board. 7 - 13 being on the top board (game side) facing the light. 1-6 are on the video board. The game works as far as the sounds, controls, and maybe half the images... Such as the building, Windows moving up and down, score, some text. I'm just missing some sprites like the player, birds, building name at the bottom. Does anyone know which chips I should be looking at to diagnose this? Which chips 1-13 are which exactly? Thank you!
