This Bally guy has a question in Bally Arcade/Astrocade Posted December 25, 2021 11 hours ago, bah said: What are the tv's? CRT, LCD, etc. TV's are both LCD's. 11 hours ago, bah said: Is the problem always repeatable, the first board is always B/W on the upstairs TV yep 11 hours ago, bah said: I would replace the RF module and cable just for fun to be sure the problem isn't related to those. I tried that too. 2 hours ago, Gunstar said: a weak connection where the RF plugs into the board that the second board doesn't have. The 8 RF pins were all reflowed, as were all the pins on the data chip. I think if this were the issue, it wouldn't display correctly on the TV downstairs, but what do I know?!?!?!? Keep the suggestions coming! In the meantime, I am probably going to pack it up and ship it off for a 2nd opinion. I hope it "doesn't work" for the lucky recipient, or he may not be able to figure it out either.
