LG 50PX4DR 50 in. Plasma TV Logo

Black screen/No TV Guide

My LG 50PX4DR was working fine for 18 months but now we get sound but no picture when we first turn on TV. Get normal picture once we hit Exit or TV Guide button on remote.  Pressing TV Guide again results in black picture (and no graphics or anything) so we cannot schedule TV recording on built-in DVR.  But can record manually and playback fine.  I have tried the normal setup functions to no avail.  It seems like we need the software reset to factory condition and/or reloaded.  Is there some magic remote key sequence I can use to do this and/or can I download software onto an SD card or something? Thanks

    I had the same problem, LG replaced the main board to repair, Set has a two year warranty

  • GaryCinci Oct 18, 2008

    I ran with it like this for months but then it started being unable to playback new recordings.  I ended up getting the board replaced.  The manufacturers warranty had expired but, unusually for me, I discovered I had purchased an extended warranty and that covered it.  The new firmware seems to be better at recording the titles of shows but it still has the design quirks like stopping the show you are replaying when it starts a new recording.

    To people who say "LG replaced the main board" -- could you please specify what the main board is? A a part number would be very useful.

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.

My on screen TV guide no longer works, and my TV keeps losing time (between 10 and 20 minutes). I'm not sure how to fix this. Is this a hardware issue or a settings issue? Has someone else had prior...

Do you have cable TV? Many Cable TV companies have recently (over the last year or two) quit sending TV Guide data. You can get it through an external antenna connected to the TV's antenna input if you are within range of an ABC or NBC and a PBS affiliate for the clock auto set.

But if you still have TV Guide service, some of these have failed circuit boards for the TV Guide, ( usually shows a complete black screen when you turn it on or hit guide button.

Tv made a loud pop sound then went black...sound and all functions are normal just no picture

This is a common failure in many PLASMAs. One of the boards in the TV blew. Most likely It is going to be the Y-sus but could have also taken out the Z-sus(sometimes called the X-sus) and the Y-drives. These boards put and maitian the picture on the screen. The best way to tell is to check the voltages on the boards to see how extensive the damage was but I would defintly start with the Y-sus.

Very faint picture but sound is fine on my 50" Zenith plasma

Sounds like the Z-sustain board went bad. You will need the board replaced so make sure you find an LG authorized servicer.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).
