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.

SOURCE: 50 inch plasma zenith tv power and picture comes

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.

SOURCE: zenith 42" plasma p42w46x

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.

Zenith plasma tv wont stay on model:z50pj240


This could be caused by multiple things. The first problem that comes to mind is a bad power supply in my experience. The second problem that comes to mind is possibly a bad t-con or backlight inverter board. Could you tell me, when the TV powers back off can you see a picture in on the screen if you shine a flashlight up to the display?

After warm-up screen flashes and loses color but comes back on and off intermittidly. This is a 50" Zenith Plasma tv. thanks.


Sounds as if a cable connection is bad. Check the cables first. If cable are good, change inputs, if cables are bad replace cables. If it's component, make sure that red, blue or green didn't come loose on both sides...the tv and the source. If you still have problems, check for red video noise on the screen itself, preferably when it's on but with on input (black) If you notice this, your plasma is failing.

A buzzing noise coming from inside the tv but still buzzes when on mute but doesnt buzz when tv guide is up on the screen or when a channel is showing what time it starts


plasma tvs buzz a lot, depending on screen brightness. its probably normal but if you can hear loudly over your volume, may be a bad board or plasma panel. from behind tv, left side = y board, right side = z board, middle = power board ---- bad panel can buzz from anywhere... if you hear all parts buzzing, its probably normal plasma noise

Loud buzzing


check your connections again, if you have the audio and video reversed you will get this exact problem no video/ fuzzy video, and squealy noise out of only one speaker (other will likely sound correct) You're watching the sound channel, and listening to the video channel basically... hehe
