Question about LG 42PX3DCV 42 in. Plasma EDTV

2 Answers

Plasma screen went blank.

After a short pop the screen went blank. There was the smell of electrical burning. I unplugged all the equipment. After a few minutes plugged the equipment, i.e. plasma, cable box, receiver, and dvd. All other equipment turned back on and appears operational except for the plasma. Light comes on showing power, but no picture. If it was just not receiving a signal, a screen saver would be on on the screeen showing no signal. Any suggestions?

Re: Plasma screen went blank.

It could be a few components like the tuner or the component that processes the still images to display on the plasma screen, I forget the technical name for it. Either way you look at it, a part has clearly blown and there's no quick fix. You'll need a professional to take a look inside it to determine what's wrong with it. However, if you're confident enough to open it up, you'll most likely see burn marks where a component has burnt out. Mind, if you open it up, not only are you putting yourself in high danger, but you'll void your warranty if you still have it left. If you do in fact still have warranty, my only recommendation to you would be to return it under warranty. Good luck!

Plasma made a loud pop then shut off and will not turn back on. There was also a burning smell. Any suggestions on a fix and price is appreciated.

Having similar problem and it sounds like an obvious short circuit if you heard it and can smell it, and it probably took out power supply fuse, so the first thing to do is pull off back of TV and look for obvious toasted components by eye or smell. Capacitors sometimes will pop when they go, and you can see the tops will be bulging out, or black marks, so look and smell all large capacitors first on power supply main board, then check to see if fuse blew. Sometimes the obvious is easy to fix.

Good luck,

Either the fuse inside the unit blew or the vents got clogged up and the unit overheated. Could you smell a burnng smell? Another possible problem is the power supply, if you live in an area with frequent voltage flucuations in sine wave or spikes the power supply is the likely culprit. If you have never worked on a plasma before I do not recommend you do it yourself though, the cost of a pro is much less than the cost of burning down your house by incorrectly fixing an electrical problem.

The screen on my lg 50" plasma went white and

The power supply has obviously failed. An Authorized LG agent will advise on repair cost. If it is just the Power Supply it may be not too bad but un authorized technicians do tend to hike the prices up to cover the lack of experience.
Write a nice letter to LG, they may well listen. It's worth a try depending on where your location is. Lean on the age of the set and that you are very dissapointed that such a good named product should have failed so soon.
Good luck.
