Magic focus --blue and yellow sag in the upper left area of the screen


This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.

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.

Slight distortion of color on screen


I have this same problem. This is caused by a defective optical block. Sony currently has extended coverage on optical block replacements, but not for the symptoms our tv's display. After several phone calls, I was told they would cover replacement of my optical block (a $1000 part by the way), but I would have to drive it to another state to one of their certified service centers. Once it was there, they suddenly decided to NOT cover the block as promised to me on the phone, and conveniently told me although my block was defective, that it wasn't the right kind of defective. So I was left with wasted time, miles, gas, and a diagnostic charge for an unfixed TV. visit http://splinke.googlepages.com/sonyrearprojectionlcdtv-opticalblock for more help.
