OK hope this is the right forum. I bought a Baby Pac and find the mpu corroded thanks to the battery. I buy a Stern/Bally ultimate mpu. I installed it today. I checked my board voltage at test pt. 2 and got 5.31 v . Anyway with the board installed after checking v I turn it on. The vid. screen is messed up. See attached pic. the pinball part plays great other than some burned out bulbs. I tried all 7 different adjusting knobs and the best I could come up with is what you see in the pic. Does anyone have any idea what to try next or does anyone know someone that makes house calls for this machine?I live in the Portland, Oregon area. Any help would be great. Thanks.
