Question about Zenith Z50P3 50 in. Plasma TV
There is a buzzing noise coming from the tv. The audio works but not the picture.
Plasmas are like tube TV's(CRT). Once the plasma tube breaks, air gets in, plasma gas gets out. And that's it. They are an enclosed vacuum picture tube. I don't know why people buy plasma. The newer LED have a much better picture. Rich people who swear by plasma, are ridiculous in my opinion. Again, if plasma tube breaks, thats it. Any wrong jarring can break a plasma tube.

Stretchlimo. Thank you for such a good response to this person's question. I am also having the same problem. However, I found that if you push in on the power button and hold it in, until the Green "Power on" Light stops blinking... the video will resume. I do want to go ahead and get said part, that you were speaking of. Is it a Power Converter/Transformer, or something along those lines? Can you point us in the right direction; as to where to get said part? Thanks again.

I have the three zenith plasmas, I've fixed the two that were flickering. The one with the verticle lines, I sawpped the Z-SUS and the Y-SUS from the good TV to the bad and still had the white lines. I looked at the two boards hooked together with 3 aluminum covered ribbon cables that are in the lower center of the TV with all the video inputs, on the far left there is a right angle connector that has about 20 pins, the white cable comes out and goes under to a circuit board this looks like this cable supplies the video signal to the screen. I disconnected the cable and the screen went black, all the voltages going into the video board are normal, so there must be something fried on one of the two boards, there are a LOT of electrolytic caps on those boards. I will post when I figure out whats cooked, you may have the same problem too.
