Thanks, I'll go ahead and try that and see what happens. Could it also be the capacitors on the main board? I'm only asking because it seems to be fairly consistent with the "works for a few minutes, stops working for a few hours" pattern. Which makes me wonder if a trace crack could cause something that consistently. It looks like the two ceramic capacitors are connected to the same trace as the one leading to the pin for the Up button. Edit: unfortunately shorting the traces did not seem to help the issue. Standard behavior of worked for 10 minutes and then stops working.

Yes every other button on the controller works without issue. Another observation I made after testing the controller again after letting it sit overnight, the up button worked for a few minutes before stopping again. It seems like something about hooking it up causes the issue, and once the controller has been unhooked for a while it works for a little bit. I've looked all over the traces connected from the button to the IC but I can't find anything that looks like a crack. How small can these trace cracks be?

Hey guys, I'm looking to see if maybe someone could give me some advice on repairing a pro controller I found recently for a great deal. The issue with the controller is that the up direction on the d-pad does not work. Here is what I've tried so far. 1. cleaned the contacts - no effect 2. reflowed all the solder connections - d-pad worked for about 10 minutes and then stopped working again 3. replaced the diode right after the contact for the up button - same as before and the button worked for about ten minutes and stopped working again. At this point I'm not quite sure what else to try troubleshooting for the controller as the button sort of works for a while and then doesn't. Any help would be greatly appreciated.
