My tv was made in June 1992. It has worked great until yesterday. When my kids were watching it the picture and sound went out and the TV started to make a popping sound. It continued to make the popping sound until it was unplugged. When it was plugged back in it only made the popping sound when you hit the power button.
When I opened the back and took the basket out and took the front panel off, I could see a spark when I would hit the power button( it also makes the pop sound). The spark looked like it was coming from around the copper wires on the center picture tube.
