my marquee 9500lc no HV, no picture, the rear LEDS always showed H-fail with hot startup ( cold startup didn't) . the HVPS is healthy,( which had been swapped by another healthy HVPS to comfirm) ,yesterday I swapped the Q501 on the daughter board on the HDM with the one on the CCM, when powered , no H-fail showed at any case any more, but still no HV, no picture!  any idea? thanks in advance

From what you are describing, it most likely is a problem with the CLM or HDM. Do you have spare boards to swap for those?

The machine worked properly until couples of weeks ago, when i powered it on, hearing a bam, since then no HV, no pic.

OK, best thing to do is to send me the boards for testing and repair. Those are the most likely problems. I'd also then change all three HV leads going to the tubes, since that's most likely where the arcing took place that caused the BANG!
