My zenith plasma tv popped real loudlike a car backfiring and then the tv picture went black. power on green light wil turn on but it automatically cuts itself back off to the red light


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.....

I have 3 black stripes on my Zenith 42


Turn off the TV then unplug it. Disconnect the cable connection and clean the terminals. If the stripes still exist, you have a bad TCP (tape carrier package). It is responsible in transmitting color information to the display panel from the X-Drive (A-Bus) Board. This is not an easy repair. Service of an experienced or a qualified technician is recommended.

Zenith p42w34 will not turn on


Before Opening, double check something for me and post a follow up. I have this tv and I believe it has dual power buttons. One main and one secondary. A remote can't turn it on unless the main power button on the bottom left is on. 
Please post follow up.

TV's on. No Picture...No Sound


Have a problem with Zenith 37 HDTV. Medel number: Z37LZ5D As wathcing TV, along with 'pop' sound, TV went dead. LG service center gave an advice to unplug the power cord and press ON/OFF power switch about 1 min. Then plug power back and turn on the TV. Well, the green light blink for a while and solid green, but still no screen, no audio. Search the Web and someone suggested to replace Power Supply Board which will fix the problem. Again, search the Web and came out with Power Supply Board. LG Electronics/Zenith 'Power Supply Assembl' with $124.95 from PartStore.com. Is it the right solution? Do I have to replace entire Assembly Board? not just replacing some fuse? Any cheaper way to do? If I have to replce PSA board, any suggestion to how? Comment posted on Apr 22, 2009 I have a basic knowledge of electric and electronics, such as rewiring entire house for renovation and assemble entire computer from scratch.
Actually, the TV belongs to my father and the problem that I stated was based on what he told me.
So the question is based on the symptom that I posted, how sure are you that the problem is the Power Supply Board?
Is it good to order PSB? Comment posted on Apr 23, 2009 Purchased 2 and half years ago. Expired one year warranty. Comment posted on Apr 23, 2009 Zohail,
This is LCD TV.
There is no problem with the wall socket nor current.
I put other appliances on same wall socket and worked.
It has to be internal problem.
As I mentioned on the main post, there was a 'pop' sound while watching and TV went dead.
Turn on remote control, there is blink green light and then green stays on, but no sound, no screen.
Turn off remote control, light turns red. Comment posted on May 14, 2009 I fixed the TV.
Orderd power supply board which cost me $136.51 total.
Replacing was simple.
Just removed the rear panel cover then electronic board housing cover.
Took power supply board with all the connector cables and replaced with new one.
Problem was a transformer connector which got burned and blow up the plastic cover.
But no problem with fuse and capacitors.

Thanks all for advises.

Green light blinking- no picture


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.
