Looking for help on my first antique game. Bought a US version Paragon a few days ago. All original except for a recent allteksystems MPU board upgrade. The only thing I can find that doesn’t look original is one of the molex connectors leading into the light driver has been individually wired without solder on the wires (electrical tape only) and plugged into the board individually. The upper right side. See picture. The game played great before and after transport to my mancave. I ran a diagnostic via the test button on the coin door last night and everything came out great. Played about 30 games that worked proper before the score displays simultaneously stopped showing anything other than ones and zeros. Then I couldn’t start a game. Flippers worked but all other solenoids were inoperative. Meanwhile the MPU originally would react to pushing the self test and reset buttons. However, after 4-5 on/off cycles only the D38 5V light comes on. Nothing happens when I push any of the other buttons on the MPU. I've never seen the red overload light come on. Will not self test on start up as it did before with the 8 light blinks. Now the playfield lights come on when powered up but nothing else. I unsuccessfully tried the MPU clear system process. It will not respond or blink as as it is supposed to at the end of the protocol. All the voltages are as they should be on the MPU test sites (TP2-6) and solenoid driver via TP1/GRND has 5V. I’ve checked all the fuses, connectors, pins and am wondering if the MPU might be bad?They are supposed to be bulletproof.
