I have been trouble shooting a Toshiba 42hp83 Plasma TV for some weeks now. In searching the internet, I have only found two situations like mine, however no solutions and was hoping that maybe somebody has seen this type of issue or has some insight.

The plasma display, Y sustain, X sustain, and Y buffers are all Samsung brand.

My TV starts up fine with a good picture and after some 10 or 20 seconds, the picture will start to degrade (what I call pixelate) to a picture with a line going through the middle of the screen, from left to right with the rest of the screen...

Hi, I am Matt. I am an electronics hobbyist for quite some time. I have worked on many an old TV (tubes and transistorized), radios, amplifiers, etc…. Have been out of it for awhile, busy with work and family. Acquired a broken Toshiba Plasma display, learning a lot, I am hoping to share my experiences as well as get some further insight on these displays. Thanks for reading.
