I had that too on one of those... I never was able to get it down quite at specs though. I changed everything, even the varistor. Before I worked on it, the HV was skyrocketing to who knows what, and I got it to regulate, but still about 26KV peak at 0 brightness. Should be 21.5, if I recall. It was about 22KV at normal brightness though.
