Sounds like it could be a problem with high voltage stages. Definitely a job for a TV technician as it is dangerous try to repair it yourself.

I own a GE 31gt740 and I heard a squealing noise a few times, but TV still worked. Then, I turned it on one day, heard the squealing noise, then saw a little smoke, some crackling, and no sound or picture....


I think that the problem of your tv is the flyback transformer. The noise you are hearing is the high voltage, it is leaking from the flyback transformer. The smoke you see may came from the flyback or the capacitor. To be sure to the problem, try to remove the back cover of your tv but be sure to unplug it. Try to plug it, then turn on your tv but you should turn of the light so you could see the high voltage that is leaking but be very careful when doing it.

Model 35 gt695 no pic or sound .went to move tv to clean and seen a flash on top right of screen.worked fine after that .in the morning came on fine for 10 minutes then heard a pop and it went off.light...


Most likely the high voltage transformer took a dive. If the picture was still good before it went out it is probably worth a check out fee. Another possibility is that there was a loose solder joint developing and moving the set around helped the loose joint come completely undone. Thanks

My tv went dead during a lightning storm. I heard


The sound could have come from one of your power capacitors. You could tell if one of them is no longer operational by looking at them; they will be burned, or blistered, or will be bulging. If this is a CRT type of TV ensure that you only look inside if you are fully aware of how to deal with the lethal voltages that are stored on the inside of the unit.

Picture and sound gone


The Flyback Transformer is probably shorted to the core and shorted out the Horizontal Output Transistor. Changing both will probably fix your problem. Let me know if this helps.
