Sometimes during operation, sometimes when first powering on, the blue color seems to be out. I can detach the blue component video input feed, power off the set, reattach the blue component feed and power the set back on and then my colors are great. Sometimes it lasts for days, sometimes for a few hours. Any clues?
Yes, the cable has been replaced. I've narrowed the problem to the tv, as in my original post, if I detach and reattach the cable I can make it start working again. Almost like something needs resetting or something.

I know this may seem dumb but if you are using component video (the red green blue with the white and red audio cables) it could very well be that the green cable (carries the green signal) is the problem. try changing the configuration (ex: use blue to carry the green signal and vice versa) if the green starts to work and the blue stops then its just your cable.
This is an LCD rear screen projection TV. There is a Red, Green and Blue LCD pallet that is mounted on what they call an X-cube. If all you are getting is Red and green then something happened to the blue pallet. Either the Ribbon connector came off or is loose or something worse. How hard did you mover it? Another thought. How is it hooked up. If component then this may be the issue as component video connections are Red, Green and Blue. Just a thought. Let me know. Blessings always, A/V Media Tech Guy
If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.
Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.
There should be a jumper somewhere around the color wheel. I am having a problem with my color wheel, and after doing a lot of research I found that people that have the same problem as you changed the jumper setting. Try looking it up here on the net. Should solve your problem.
Make sure your audio is connected properly as well as your video. I
have found many people often mistake the white for yellow and vice versa.
White and red are audio. Yellow is for video.
However if you have a the Component Video Cables, which are Red, Green, Blue, Black and White. Make sure these are hooked up correctly people often mistake blue and black and sometimes green for the colors. Make sure when hooking up the cables you have plenty of light to avoid confusion.
Adjust the green & blue CRT screens to match the red. Go
into your picture menu adjust, turn color all the way down to a black &
white picture. Now adjust each CRT screen so that you end up with a true black
& white picture. Then adjust each focus control to get a sharp picture, and
adjust each CRT focus one at a time for clarity by covering the other two up. Then
go back into picture adjust and turn color half way up, you should see a
If you cannot get the blue & green to even out to a
black & white screen you have other problems such as faulty CRT card on
back of tube or it could even be that the video IC is faulty. If this is the
case, then you may have to get a competent local technician to check the TV and
get the necessary parts replaced. It could set you back between $200-$400, depending upon how many components need replacing.
You can also try a hard reset..Unplug all cables, including power from
the back of TV. Wait for 4 hrs and reconnect them. Try and see if it

You're using YPbPr (Red/Green/Blue Component) cables, right? Make sure you've got them in the right inputs and that the cables are FIRMLY attached. (Sometimes they seem attached even when there's a half-inch or so of space still)
