Really hope someone can help. I have a Pinbot that works completely fine other than all displays, including player and match displays, blink/flash/pulse very quickly. The diagnostics LED does the same and appears to be at the same rate. I replaced all of the electrolytic capacitors on the power supply. This made the displays brighter but the blinking/flashing continues. I really feel like this is a power supply problem but am not certain. R1 and R4 appear to be good although they also look like they were replaced prior to me purchasing the game nearly 20 years ago.
Any thoughts? Has anyone seen this problem? I can get a get a replacement power supply for $115 from www.pinballPCB.com but want to make sure this is the problem before I do.
