LG 50PX4DR 50 in. Plasma TV - Page 3 - Answered Questions & Fixed issues

Blown power supply, usually, unit going into PROTECT. Don't keep trying! you'll only damage more components. Change power module or Professional repair..

If you can see a faint picture with streaking you most likley have a defective Zsus module Part Number 6871QZH036B Description PWB(PCB) ASSEMBLY,DI List $226.14 Please rate my info

The power supply is going in to protect mode. Most often this is a power supply failure, or a failure on one of the circuit boards that is causing the power supply to go in to protect.

If the power supply fault is not too complicated an experienced tech may be able to service it without changing the compete circuit board.

The tech will service this by substituting boards to determine where the failure is occuring. Then he will change the board to fix the fault.

Did you try another HDMI cable?

Did you try another DVD player?

If the above try-outs does not work for you, then the fault is most likely with the HDMI input processor area. For this the set will require service.

I had the same problem -red, vertical bars along the right side of my Samsung 42" Plasma- and this is what fixed it: Removed unterminated cable.  
I had hooked up an HD video camera to the set about two weeks ago.  While I disconnected the camera I left the other end of the connector cable plugged into the T.V..  As I've since learned from friends who work in television, this is what's called an "unterminated cable" -meaning one end is unconnected.  It can lead to problems with electrical interference and appears to have been the problem in this case;  When I disconnected this cable from the T.V. the red bars went away.
So, check your cables.  Make sure everything is properly connected and get rid of anything that might be picking up interference.  
Hope this makes sense.

Have you tried with a new scart or htm lead?

hi there, i have the LG 50in Plasma and just updated the channel connection by doing the following:

1. Make sure your remote is in "TV" mode.
1. Press the Menu button.
2. Highlight "Auto-program" (Should be the first item on the Menu)
3. Scroll over to "To Start" and press OK.

The TV will automatically search for all available analogue, digital and HD signals and may take a few minutes.
Once complete, it will return to the last program you were on and you will find all channels available.

To check the guide or the time, you need to press the "guide" button. Make sure your remote is in "TV" mode. Alternatively, pressing OK at any time shows you the time and channel that you are on.

Hope that helps!

Check the menu for ,probly under settings called convergence,, if it has it ,,that will make it right,, it realines the colors,,soposed to do it periodically,, or when you move the .tv. well ,,good luck with that

It can be fixed but about $300 in parts.

Replace four boards. Y sustain and drive boards as well as the 2 xdrive boards. About $600 in parts.

anytime you connect componet signal (green red and blue)to regular video inputs (yellow) end will have same effect. make sure that if you are using component signal from source(cable box,dvd player etc) you have to connected to component input in the set.
component signal will use green red and blue for video and red and white for sound.

In that case two things might be happening. 1. HDMI/DVI cable you using might be faulty you want to change that or 2. The HDMI input of your TV set might be the problem. I will suggest you use component cable instead, I am talking about the 5-color-coded (green, blue, red and red/wihte) cable to connect the set top box to your TV.

When you hear the Pop, the Plasma display is Gone. There will be two large Capacitors on the power supply board that are swolen as well. Your only course of action is to call LG and beg for assistance, as the Panel itself is a 1600.00 dollar part.

Mine is doing the same thing. It's under warrenty and a guy is coming to look at it today. I will post more info once I find out more. I had called LG and they told me it's a problem with Gemstar and an upgrade that is going on with them. Not a TV problem. We will see.

It will have to go into the shop! Our LG Plasma did the same thing twice now.
