The color on my TV is messed up. It appears green and blue. I can see the picture fine, it is just it appears to be lacking red and possibly some other colors. I have gone through everything in the menu trying to make adjustments but I can't find anything to adjust the individual colors. I read that someone mentioned going into "service mode" to make adjustments, but I don't know how to find the service mode either. It has the same color problems on the HDTV channels. The TV is about 2 years old. Thanks.
After spending a day trying to fix the TV, I found out the problem was actually with my cable box. I have an HD DVR recorder. We unplugged the cable box and plugged the TV directly into the cable in the wall and it worked. So we took the cable box back to our cable company and got a new cable box. (Can't live without the DVR!!)

the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.
You can try adjusting the color output. There are two ways to do this: 1) In the service menu (I don't know the codes or parameters...) I will not cover this for lack of info.
2) Via the focus block (Very touchy and difficult to get the mix right again if you get too far off)
If you take off the front cover there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)
It sounds more like you may need more red in the mix or just less blue and green. There is a screw for each color. Do not mess with the focus screws, just the ones labeled 'SCREEN.'
Barely turn the red up. Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it. Very HIGH VOLTAGE. I found that out the hard way.
Do not turn andy of these up too high or damage may occur and the TV may detect a short and shut off.
I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.
IF IT IS HOOKED UP WITH COMPONENT CABLES (GREEN, RED, AND BLUE) FOR PICTURE AND RED AND WHITE FOR AUDIO, MOST LIKELY THE RED ONE IS NOT SEATED PROPERLY, CHECK BOTH ENDS THE ONE CONNECTED TO THE TV AND THE ONE CONNECTED TO WHATEVER THE SOURCE IS ( SATELLITE BOX, CABLE BOX ETC.
Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference. If your TV has a Color Temp setting, you will normally have the following options to select from:
Cool: Gives the picture a cooler, slightly bluish appearance.
Neutral: Gives the picture a neutral, more natural look and appearance.
Warm: Gives the picture a warmer, slightly reddish appearance.
If your TV has a Hue setting, follow the appropriate step below to make adjustments:
Move the setting to the right to reduce the reddish appearance.
Move the setting to the left to reduce the greenish appearance.
I had the same problem with my TV, but the hue was blue. I was told that not only did I have to replace the picture tube that wasn't staying on, but I would have to replace them all because they would not mix properly. After much investigation, I found that there is an adjustment for a variable power supply to each tube that can brighten and lighten each tube. I adjusted the RED pot and my picture color issue was resolved! To access this adjustment you must remove the front panel on the TV. At the bottom corners there are two small screw covers that you must remove. Then un-screw the screws under the covers. Then pull the front panel off of the TV, (it hooks under the top near the screen so it will swing out from the bottom). Now remove the wooden panel in the center, (four screws). The pot adjustments are at the bottom of the TV. They are marked for Red, Blue, and Green. They are extremely sensitive, don't turn them much! If you over adjust you will get red, green, or blue lines on your screen. Adjust back down to remove these, (this is also the remedy for removing these lines that can appear over time). Good Luck and God Bless!
