Re: Strange Delta DPS-222BP power supply behavior

I have the same issue with my PN-E702.
The backlight turns on when cold for a few minutes then shuts off. Once it has done this the backlight will only flash momentarily and stay off.
No signs of overheating on the transformers.
Seems like a common issue. Any other insight would be much appreciated.
BTW i did check the schottky diode and it tested ok.
Power light does not flash any errors.
Thanks,
Serge
