Zenith plasma I have a zenith plasma (Z50PX2D) it turned off itself and now when trying to turn back on will blink a green light three or four times then go back to the standby red light. I tried unplugging the tv for 10 -20 seconds but still no help.

My 42" zenith would try to turn on then go back off. LED would go red back to blue. I replaced the YSUS board and it works again.

I had AWFUL customer service. (Sherry is DREADFUL her # is 1-877-543-8325 she is in"executive services". Ask to speak to her directly...if you would like ZERO help.)

They WILL NOT extend the warranty, even though they know there is a defect with this AND other models. Zenith name on the front...LG guts in the inside.
Ours turns on, screen black and then clicks three times and then turns back off.

Something blew.... like overheated and just basically blew up..... Was it on for a long time? You may to check your warranty to get it fixed or a new one.... or you may have to just buy a new one....

There's an over current fault in the power supply or the Y-sustain convergence board. The loud pop was either a capacitor or pico-fuse breaking from excessive current overload. Sounds like 2 or 3 mosfets have shorted at the gate ends. Plasma TV's always have this problem because they generate too much heat and the components cant take the load conditions. Make your next TV an LCD...

To fix this problem have your local repair shop do it for you.....

any questions please ask.....

You probably have a bad x or y drive board. Sometimes both. The set is trying to come on but detects an issue and quits.

Got the same problem and got a $ 700 quote for a board with a suggestion to replace a related board for a, w/ labor total of $900.
Considering spending the money for the satisfaction, and sending it to the president of Zenith and telling him "where he can do with it" . Never impressed with their products before;this cans it.

Sounds like what happens after the POP. Mine POPPED then went very faded for 5 seconds then nothing. Upon turning back on it blinks green 4 times then back to red off.

Technician just replaced the upper right (from the back) circuit board that conects to the panel. TV now works fine. I bought the display model 8 months ago with extended Circuit City Warranty for $1000 so I can't complain. This was covered entirly by LG/Zenith (nicest Cust. Svc. ever) so we'll wait and see what happens.

yes;and my controls rarely work unless it is kissing the unit.I also find it difficult to change the channels manually.[BOBBY](512)[email protected].

This just happened to my Z50 yesterday...10 days after it came back from the repair shop! The first repair was for the "popping" problem where the tv makes a loud pop and the screen goes black. This took 6 weeks to get fixed. For this new problem the repair center is getting hold of LG to find out what to do. I am also calling them because I see this is a major problem that people have been experiencing out of warranty. The first customer service rep told me I was out of luck but I am not accepting that answer. Good luck, we'll both need it.
