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

Your TVs CRT socket is faulty. CRT socket is one that connect the base of the picture tube, and can be located on the base card of the tv. It is soldered directly to base card and can be replaced. Unplug the base card from the picture tube neck [Caution: never damage the neck of the picture tube. Only slight pressure should be applied], desolder it out and replace it with a similar type.

It was working fine then no picture dark sceen sound work fine

More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?

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.
