    I've had the TV for a few years now and it suddenly powered off and wouldn't come back on. Found SMT resistors R812 and R811had no solder on one side. Added solder and the TV powers up now.

  • I just finished repairing the same model TV for a friend who had the same problem. My trouble shooting led me to cold solder connections on the flyback transformer. After repairing the connections the TV works just fine.
  • WARNING: IF YOU ARE NOT EXPERIENCED WORKING ON A TV, TAKE IT TO SOMEONE WHO IS. THERE ARE DANGEROUS HIGH VOLTAGES WHEN THE SET IS OPENED UP.

Older projection tv won't turn on.

id replace the tv its 15 years old and past the livlihood they usually have. it would cost more in parts to repair it than to go out and buy a new one. im sure you probably already know that though. have the tuner checked but i dont think it will save the tv but if it comes on when the cable box isnt hooked up then the problem could be in the tuner. its hard to tell. the tuner is about 100.00

HELP! Fire Hazzard!

It sounds like your focus/screen block, the flyback transformer, or maybe a CRT anode lead is leaking high voltage. This could be a serious problem, or could be a simple one. You should not attempt this repair unless you know all of the high voltage safety issues involved with this TV set. Good Luck
