Can't figure out whats causing the squiggly horizontal lines that come and go on my GP-5000 (GE-imager 610). They are on all three guns and will disappear after shutting the PJ off for awhile. Sometime they re-appear if I change the RGB input frequency from 1024x768 to 600x800 then vanish after powering down and up again. They're totally unpredictable. At first I thought I fried the tubes with a power surge. Anybody?
