I think I need to repair or replace my HVPS, here are the symptoms. Watching a film last night, the picture suddenly died. Checked the warning lights on the rear (celling mounted) but nothing showed except the normal green power LED. The Moome DVI input board is showing the normal link/input LEDs. Tried the menu's, test patterns - nothing. The tubes don't show any light output at all. There is a quiet clicking/arcing sound coming from the HVPS and I think the LED inside the power supply is lit. Tried the usual pulling all the boards and cleaning contacts, reseating IC's, no change. Opened up the HVPS and there is a white powder ash on the first inch of PCB coming out of the potting compound that has a trail going up to the HV wire coming out of the compound. The only thing that makes me doubt it might not be the HV supply is that the warning light on the control board isn't lit, but that might be wishful thinking. I replaced this supply a few years ago as they were un-repairable, is that still the case ? Who is still supplying these (used).
