2 THINGS THAT USUALLY CAUSE THIS PROBLEM IS
1) THERE IS AN ARC FROM ONE OF THE PICTURE TUBE ANODE LEADS--15.00-- THE TUBES ARE STILL GOOD , JUST THE LEAD IS BAD---NOT EASY TO REPLACE ,,YOU HAVE TO CUT THE OLD ONE OUT AND REPLACE USING SEALANT ....
2) A PART CALLLED A HIGH VOLTAGE BLOCK--75.00--THIS PART TAKES HV FROM A FLYBACK TRANSFORMER ,,,SPLITS THE VOLTAGE TO GO TO THE 3 PICTURE TUBES
KEEP IN MIND ,,IF YOU HEAR A POP--IT'S USUALLY A HIGH VOLTAGE ARCING TO SOME METAL--YOU ARE BETTER NOT PLAYING THE TV

THESE JOBS ARE BEST DONE BY TECH'S -TUNICA

Tv popped and picture went out


im srry to tell you that you picture tube blew in you tv this can happen from many things as simple as a defective one .. to a bad power surge in your house ... if it is under warranty they will fix free of charge .. if not you'll have to get a new tv .. a new tv in most cases is cheaper then tryin to just by the tube .. oh and if its not under warranty .. you could always just say it surged and claim it on you home owners insurance =]
