My stargate is back to acting up. Upon startup is give all systems go and the has an adjustment failure. If you cycle through the menu the first game adjustment menu has one line at the top and is blank except for some flashing lines. It is stuck on this board until you reboot. If you start the machine with the door open and start the machine as normal then the game starts in free play with 76 lives and as many smart bombs. It will play fine but the high score screen is all dashes. I have recently replace the CMOS ram and the machine was perfect for about 6 hours, now this. The machine has a switcher and li battery installed along with new cmos ram. I switched the new cmos ram (5114) with a new 6114 and the problem continues. I have reset the cmos. The rom selftest says all good. I have pulled and cleaned the legs on every socketed chip. Could i have a corrupted eprom??? Anyone have any ideas???
