I’ve got an SER4 which has decided to stop powering up, for the most part. Once in a while, after a LONG time, if I plug it back in, it will power up. However, for the most part, it doesn’t power up. I’ve tried replacing all cables and peripherals, as well as different power supplies with the same specs as the original one.
I’ve tried resetting and re-seating the hardware inside, but no dice. Anything else I should do or try to get it working again?
