error 001 - Mains undervoltage fault
Got 765DC X ray. When powered up in the morning - it used to start in seconds. After time it was 10 minutes. Now - over an hour. After it starts it works properly until it is switched off for hours. I have checked all LED for faults. Only one (D34) is showing up the mains undervoltage supply too low. The mains voltage at the board had been measured - it seems to be ok (230V). I was thinking about the RT1 or RT2 (thermistors) - measured all ok. Test points have been checked. All electrolityc capacitors on the converter PCB had been replaced. The error 001 still shows for over one hour. Anyone has had the problem? I found on eBay US someone is selling the repair service for error 001 ..... so the problem exists in more cases. Reply
