While watching, my TV started crackleing, the screen went black, smoke and sparks shot out the back last night. We imeadiatly unplugged from surge protector. (The TV turned off automaticlly) When plugged back in, and turned on again, the same thing happened. About a month before the fireworks, the screen would go black a few times and then shut itself off. After a minute I could turn it back on. I called GE and they asked how old the surge protector was I and I said probably 2 years (as old as th TV) So I purchased a new one and TV worked fine for 2 weeks, then shot sparks. Please help! I have a feeling this could be an expensive fix and need to know if I should just buy a better TV.

Re: 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

Pop and flash meaning that the picture turns on and off? Many people's tv eventually just turns off all together. Furthermore, if you notice a crackling sound, it isn't just the sound of the tv turning off, it is the sound of sparks and flames emitting from the back of the television. Take notice of this as it is a fire hazzard. If you do notice this, please report the problem to the consumer product safety commision. I beleieve this common problem with large sparks and flames warrants a recall.
Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.
This part is called the Focus Block and has 6 controls, 3 for focus and 3 for screen. The screen is the overall brightness of the CRT and the focus is the sharpness. The part can be ordered by description from any RCA parts distributor but the controls should be set by someone with experience.
