Bought this TV used on a hope it might be easy to fix (Limited Funds) The color works, but from the bottom of the center screen to the top and right, is an area that does not have color. When people are on in this area, they look light purple. If I switch to a Video output, it is a blue screen with this affected area being green. Definition is fine, and so is the screen, just weird color through this area. I have adjusted color controls, but am unable to correct it. Other than this problem, the set works fine. Please tell me that there is still hope. Thanks.

I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps
Sounds like you have a bad joint on the tv circuit board somewhere.There is another thing it could be if you have a scart lead connected. Pull it out and check to make sure none of the pins are dissapearing inside the plug. Sometimes they slip inside. Check both ends of the lead.
More typically, these color uniformity problems occur without respect
to which input or cable is used. The one exception is when a bad
component cable or component cable connection disturbs the color.
If you're only getting the problem when viewing through the set-top box
and HDMI cable, you may try changing the cable, having the box
inspected or replaced or tweaking the many XBR1 custom color settings for that specific input. If you are experiencing a genuine color uniformity issue such as the
green haze problem regardless of input after allowing the set a
reasonable amount of time for warmup, you may not be able to get it
fixed to your satisfaction. Sony's "cure" in most cases has been to
replace the optical block. Last I heard, this major component was on
back order.They're going to want to do a service call on your set first, of course. If they look at your set and tell you it needs a new OB, I wouldn't
waste time being put on a waiting list for the new part. That may never
happen, or at least not in a reasonable timeframe. OB replacements
don't always go smoothly either; it's a major repair requiring good
technician skills. Best bet: go for the XBR2 swap, as a few others have
Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv. If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.
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.
Also, on what source is the problem happening, through sat or through off air antenna?
If you're on HDMI I'd try component. Then, playback the affected video and see if it's reproduced w/ component.
If it's on ota only, you may have a loose tuner cable inside. It's easy to fix, you need a torx t-10 screwdriver. Unplug the unit, take the 5 torx screws off of the back cover, and on the right side you'll see 2 cables running from tuners in the front to a splitter that connects to the tuner for ota on the back right. Just make sure the connections are tight with your hands only, don't over tighten them. Also, make sure you don't touch the power supply when you have the unit open!
