My Tv turns on, but then shuts off in a few
It is most likely a problem with the sets power supply. If it is still under warranty, exchange it as soon as possible. If your warranty has expired, find a good TV repair shop locally and ask for an estimate.
One thing you can try is a "cold start" of the sets processor. Unplug the set from the wall for about 15 minutes, then plug it back in and try powering up. Sometimes this will fix the problem.
Comes on plays a few seconds and shuts right off

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
I have audio but no picture on my Zenith Z50PG10 50" plasma tv?
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.
