Re: No Pic or Sound

It sounds like a defect in the horizontal drive or HI voltage circuit. Could be the Horizontal output transistor , and /or the flyback transformer, a short in the scan derived power supply on the output of the flyback transformer. If your not aware of the HI VOLTAGE issues and have soldering experience you should seek a pro to assist ya in this repair. If you do have the experience, get a schematic and start with the hi voltage circuit. Good Luck

Been gone 3 months, came home turned on tv and had a pic for 5 min,it went out, sound stays on and can change channels but no pic. Turned on again after leaving set off for an hour, again, sound but no...

Had the same issue sound but no picture, try wiggling the connections to the back of the tv, if that does not work try using a different hook-up, I ended going from the component jacks to the DVI hook-up and this took care of the problem, hope this helps!!

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

No pic No sound

I would call PTS at 18008447871 and find out how much a new deflection board cost, because by the time you find out what is wrong and start replacing things you will be out more money. Not including the smell that means probably the flyback was burning or arching.

No Picture

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
