Try to reset the TV to factory defaults and see if that helps. Record your color settings and any other setting your have in your config before dong this because all will be lost.

Hello,

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

You can look at the sample of the power supply board, the picture with the soldering side has labeling of what you should have on the output of the power supply, yours may be labeled on the top side of the board, there are high voltage on the board so you must be real careful, if you are not sure, let the professional handle it if you do not have the basic electronics knowledge

Since you do have sound, that means you do have the 5v and the 12v but may or may not have the 24vdc for the backlight inverter.

Hope this helpout

Looks like you have a bad connection between your TV and your signal source....

Are you on cable? satellite?

all it takes is one bad connection to wipe out 90% of your signal...

Broken plasma screen


You need your Tv product code wich is located in the back of the TV next to the serial number.
you can get one directly from LG ($500-$800) or you can try EBAY, look for a TV non working with a good panel, it doesn´t matter why is not working as long as the panel is in good condition, the price range is wide but you can get one for $150-$250.

And no you can not use any 42" plasma.

I have sound but no picture on my LG 42PC5D-AB Plasma TV. I have checked the cables and they are all connected ok. turned on this morning and there was sound and no picture


If the display is totaly blank from turning the set on it sounds to me that the display is gone and all you can do is replace the display witch for a 42" set it woudl be cheaper to replace.

Zenith Z42P3 "Invalid Format" message from upconverter DVD


Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

Good luck

Plasma screen color problems


Hi
I just bought a 42pc5d plasma tv it's an LG I bought it in Sept. 07 it started doing the exact same thing your talking about here the red glow type thing. Luckily for me and I hope in your case that the tv is under warranty, although if you know someone or even a repair place I don't think it would cost much to fix (just a guess but the guy told me that it was an easy fix so don't let them try to screw you). It really is a simple fix according to the tech. You need to adjust the voltage. He took the tv and watched it until he saw the red and adjusted the voltage and I had my tv back the next day. This was about a week ago and I haven't seen it since. I hope this helps and I hope you have a warranty. By the way LG comes with a 2 year manufacturer's warranty standard so if you didn't get an extended warranty from where you bought it if it's less than 2 years old call LG and they will arrange to have it fixed that's what I did. Here's the number 1-888-542-2623. Good luck.
