Hi, Brian-
Welcome to Videokarma! It does seem like a problem with the chip, but it would also be very surprising to me that the chip itself could develop just this one internal failure. More likely, I would suspect either a power supply problem (incorrect voltage or bad electrolytic capacitor(s)), or maybe poor contact on one or more of the pins on the chip. Game machines that use that chip are over 45 years old now, so bad electrolytics and/or contacts are quite possible. Please post a reply here when you learn more, or try these or other solutions, or if you fix it by some other method. Thank you and good luck!
