Question about Vizio P50HDTV10A 50 in. Plasma HDTV

1 Answer

Screen is black, audio is fine. TV is 2 yrs old.

This TV has done this before--no loud pop--but always came back on. Now I turn it on and nothing but audio. Channels, inputs, remote, are all OK.
Is it the y-sus and/or z-sus board(s)? How do I identify these? Are the part numbers on the boards? Is there anything else to check before I buy parts? Is this failure because of a cooling issue?

The Super Bowl is Sunday. I gotta fix this thing! Please help!

I have a 2 year old LG LCD TV (model 42LG60) and I am having problems with the screen. I turn it on and everything is fine for a few minutes and then the screen goes to red or green lines that are fuzzy....


Not really a solution, sorry, but I've got the very same problem. I haven't noticed the time before tv faults, but nontheless, it greenscreens or like in your case, redscreens as well. I've been told to open the back, which I did to check the status of the capicitors, which I've done. But, the capacitors "seem" fine. No bulging or popped tops. So, I'm at a stand still...not sure what to do at this point. If someone gives you solution, I sure would appreciate your forwarding it on to me. Thanks. Robert

Loud pop, black screen, Turned TV off unplugged, then restarted power light comes on for a couple seconds then turns red. TV is about 4 yrs. old.


That loud pop you heard was a capacitor on the power supply - if you have electronic experience - pull the rear panel and look for bulged/busted or leaking caps replace them if you have component level repair experience or replace the board if you do not - also dont kill yourself- tvs have enough voltage/amperage to kill humans.

Thanks,

No picutre just black-loud pop when I turned it on


You may have blown parts, look inside and inspect the power supply module and the back light inverter board, I will leave the TV unplugged.

Turns on and off by itself


If this happens on all inputs and you have disconnected the power and reconnected it and that didnt fix it.

Sounds like a logic board issue problem is LG only warrenties tvs for 1 - 2 yrs.

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.....

check your power board, most likely that's the part that is causing the problem.

Audio but no video


If the screen is not illuminated this can be from the screen power supply, the main screen driver board, or the screen itself has failed. The service rep will change boards to service this, and adjust as necessary.

The set will require factory level service.
