Hello friends. I have a 35th Anniversary Data East pinball machine. I just installed a new CPU board from Rotten Dog and had the PPB and power boards rebuilt by Coin Op Cauldron. The game seems to work fine however there are 3 issues that I need to tend to. First off the Player 4 display is completely dead. All the others work fine. Is there something on the board that can cause this other than the display itself?
Second problem is on the PPB board. Resistors R12 and R13 are extremely hot to the touch. They are new replacements and I was told these are part of the flash lamp circuits for the Right ramp and the Mansion lighting. Would defective or improper bulbs cause this problem?
Lastly when you first turn on the game it is saying bad switch and bad coil. The testing procedure on this game is a little strange so I'm trying to figure out which switch and coil is bad. All of the coils move freely when I manually move them so I know none are stuck..
Any help with any of thee problems would be greatly appreciated. I just purchased it and am trying to get it to 100% again. Physically it's in fantastic shape. Many thanks for any help.
