Question about LG DU-42PX12XC 42 in. Plasma HDTV

2 Answers

LG Plasma picture probles

I received this tv from my mother in law, who in turn inherited it from her brother who passed away. We are not sure if this worked prior to us getting it, or if we messed something up during transport. We have none of the cords, so i found a computer AC adapter, and plugged in that, and the cable. When I turned on the tv, the whole left side of the screen is rainbow vertical lines. The right side is fine, with picture and sound. However, when i do the menu, or anything, it's behind the vertical lines, so i can't see that either.
Is it fixable? Worth it? It's a 2005. Model number DU-42PX12X
Thank You

Sounds like dry or broken solder somewhere or maybe a poor connection..could be a very cheap fox if you have the time to investigate!

Hi there. I have this same TV, and the exact same problem. Last night, i was playing around with it, took off the entire back of it to see if I could fix it. After a few minutes of tinkering, I found that if I apply pressure to the TV in a specific way, the left side of the picture comes back. Here's what I did: standing in front of the TV, I hold the top of it, in the middle with my right hand, and the upper left corner with my left hand. Then, I gently apply pressure, forward (away from me) with my right hand, and backwards (toward me) with my left hand. Sort of like trying to "bend" the screen. At some point, the picture comes back .. . the problem is, if I let go, then the colored lines come back . . . maybe one can mount it on a wall in such a way that the pressure is still there . .. i haven't tried. That's all I got.

I inherited the tv from my Mother when she passed away. The remote had been lost. My problem is, how can I turn off or reset the parental security code, setting?


hi welcome to fixya
you will need to provide the original remote sir in order to unlock the parental code. it needs a remote to set up the unlock code try to have one with your tv supplier. you can ask also to the supplier they might know how to bypass the code. hope this will help thanks.

Need owners manuel


Try this link to zenith it should take you directly to the Product support page. Click on Product Support in the menu bar then click on the owner's manuals link on the left side of the page. You'll want to select TV as the product group, then PDP TV as the product, ENGLISH for the language, and finally type in the model number.

Mute and C on the screen


The TV is in factory or demo mode - turn tv off and unplug it from wall outlet for 30 seconds - turn tv back on after 30 seconds and see if problem goes away. If not, press the (volume -) and (channel -) buttons repeatedly for about 10 seconds to see if "C" will go away. If this fails call 1-888-PHILIPS for further assistance (they do Magnavox also).
