HELLO, I JUST READ YOUR POSTING AND I THINK I MIGHT HAVE SOME ANSWERS FOR YOU. I FRIEND OF MINE TOLD ME THAT THE EFFECT YOU DESCRIBED IS KNOWN AS "PIECRUSTING". THE SNAP YOU HEARD WAS PROBABLY THE NECK OF THE PICTURE TUBE BREAKING AS A POWER SURGE WENT THROUGH IT. THE POWER SURGE WAS MOST LIKELY CAUSED BY A BURNT OUT RESISTOR IN THE B+ (HIGH-VOLTAGE) SECTION OF YOUR MONITOR. ANOTHER THING HE SAID IT MIGHT BE IS AN IC CRACKING IN THE VERTICAL SECTION. AT ANY RATE, WARMBOOTING YOUR MACHINE PROBABLY HAD LITTLE, IF ANY, EFFECT ON WHAT HAPPENED. IT WAS JUST AN UNFORTUNATE COINCIDENCE. YOU MIGHT GET THE REPAIR SHOP TO LOOK AT THE NECK OF THE CRT FOR CRACKS. SORRY I COULDN'T BE OF MORE HELP.
