Re: my tv has a lot of red color in the picture
Tt might be the problem with he color circuit board, bring it to the
repair shop for repair, or if you can do it do re-soldering to any
visual crack at the soldered lead terminal of the components on the
circuit board and then try put on to check if the problem goes away?

The red CRT tube is failing. They are rated at 3000 hrs of operation. Check the red CRT face to see if there is a lot of dirt on it or has a discoloration on the inside of the coolant chamber. These tubes are scarce and expensive. You may want to consider a new TV.
U tries go into the tv colors setup and turn down the color RED,might help?Tv could have a problems known a convergence problems,it dead very common problems for old DLP tvs.The tv have R,G,B colors lines mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv have a dead convergence board.The tv convergence board require changes 2 STK convergence ICS and some or all of it resitors too.For fixing the convergence board to solved convergence picture problems.The shop,will cost u like $300-350 for parts and labors.
Go to tv menu go to screen setting turn screen contrast to the max and screen brightness half midway point like 55.Tv real old like around ten years?Watches alots daily like 6 or 7 hrs a day?The tv CRT-(tv tube) might be to old,the radiation colors guns R,G,B insisde might not work as well as before.Have a reset setting in the colors setting?Go down to that press that,to restting for the factory colors setting.Or tries add more blue,a bit less green and red,see how that turn out?
The tv 100% have convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv have a dead convergence board,the 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be change to fix the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
First check whether all the cables from your dishnetwork are fine and connected firmly.If yes then you'll need to pull off the front of the tv, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. so we are doing real small adjustments. Turn the color off on the tv and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.
And, if it doesn't resolve your issue then it is an intermittant red picture tube, a bad red driver transistor on the CRT board, a bad connection on the blue crt board, or a problem in the RGB coming from the video jungle IC. This TV set most likely will run you about 200 to 400 bucks to have this problem fixed, unless it is the picture tube.
Please do accept this solution and revert for further assistance.
I think your cable box is old version together with weak signal caused this problem. I guess you are using coaxial cable hooked up to the TV at TV cable input jack.
At the TV there are some better quality inputs which are real digital transmission (audio and video) HDMI and components (digital video and analog audio).
The most simple and best quality is HDMI provided the box has HDMI output.
Secondly is component inputs. There are 5 cable trends in which 3 of them (red, blue, green) for video and the rest 2 are for audio (red , white). The cable box should have same color accordingly as ouput. Please note that the color must be matched otherwise you will see the screen has one color only.
Playing a DVD player to see picture good or not. If picture is good, TV has no problem at all.
Well after reading a lot more on the internet I figured out that there is a jumper that has to be removed when you update to the new style color wheel. Also when you get the new wheel there is a new set of color setting that needs to be programed into the tv itself. NOW the picture is AWESOME! better than when it was new.
