Tv going bad?

[liquid_flame]

Hello, I have a Samsung plasma pn50a650t1f. It has great picture for about a half hour and then the pixels start messing up, it gradually gets worse. The best I can describe it, there are red pixel clouds and it gets bad enough that there are spots that go completely black, like clouds. If turned off for 30 seconds and back on, it makes the TV work right again, like nothings wrong. What's wrong with the tv?

If you search for this problem you will find two possible options. One is to have a tech adjust some operating voltages in the set, Second is to replace the sustain boards which also seems to require a tech, You can check with the good folks at

They sell replacement boards and are very helpful.
