I'have an Alpha 9 CDP that randomly reboots without any apparent reason... Try to check all the caps for high esr or wronc capacity and didn't find anything. Scope the differents power lines and the line seems solid and stable. Do not know what to check for. I allready tryed to mail the arcam support and get non answer at all. Anybody knows what could be the reason of this random reset and reboots? Sometimes reboots two times before start reading the disc again... Could be some voltage regualtors that randomly fails?
