Video is taking on a red tint which is getting worse over time


check the cable connections. look at different inputs. VGA and Component cables have the colors split, so if it's turning red, green, or blue; it's likely a cable or connector.

Mitsubishi tv model wd 73727 and how to take tv apart to clean marrow


my mitsubishi 73" set is 4+ years old. all of a sudden the color is all wrong. after a couple of minutes of clear picture the colors change--blue is green and red is yellow. a little while later everything has a red tint to it and there is a line going down the center of the screen. to the left the picture is still relatively sharp, but the right hand side is terrible. I'm hoping this is just the lamp.

After a few minutes the color goes to intense red and green


My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer
