It's possible that there was a flaw in the original manufacture of the board and one of the balls didn't flow properly, but it passed QC.

- NoMoreNicksLeft 3y agoWouldn't that be DOA though? This has to be some sort of flaw that creeps in slowly.
- projektfu 3y agoThe flowed contacts could be holding the ball against the pad, making an electrical connection, but then the connection gets fritzy as everything warms up. Ideally it would show itself in the first run but I could also see it getting worse with time. I assume this occurred after the manufacturer's warranty expired.
