TM5 crashes when pressing UI

My TM5 shutdown during cooking, and after rebooting, when pressing Next at the initial warnings and disclaimers, it crashes again. I’ve disassembled and cleaned the main board with alcohol, and all the caps looked fine. After cleaning it looked ok for half an hour, but then it started doing this again. It seems that the reboot happens while it’s playing the clicking sound. Anyone has any clues of what the issue might be? It’s two and half years old…

I fixed it by reflowing the circuit that lies on the back of the display and that seems to have fixed it (been going for some months now). Seems it was a bad solder joint somewhere but I couldn’t pinpoint as I don’t have a microscope.
