The cause may be from strong magnetic pull from speakers or other electrical devices, or from age. there are fine adjustments on the inside of your projection television. there are three basic colors. red, yellow, and green (yellow and blue). unless your electrronic savvy you must be very careful adjusting your set. one wrong turn will cause the other colors to adjust out. and one wrong touch while on the inside can severly injure or kill you. but if you are going to try find the three small knobs located on inside unit by projection unit. in small increments adjust one knob at a time until you find the appropriate one. pull it back in line and reassemble unit.you dont feel comfortable dong this please take it to a tv repair shop.Hope this helps:)

You will need to replace your two convergence I.C.s.They are two large ICs mounted on a large aluminum heat sink. Replace both, and look for any burned resistors near them and replace those if needed,and then readjust your convergence.

Does it take some type of gel under the lights, the colors are a little blurry


i also have this tv. i removed backcleaned mirrior, back of screen and lenses VERY GOOD. Then turned on tv go to convergence, sepaerate cross hairs then adjust focus on lenses. Then lenses rotate maybe about a 1/3 turn total by hand. Grab ring that houses lenses and turn until cross hairs are as clear as possible. This can be done with out help by watching inside of screen. red and green are adjustable, the blue is adjustablealso but i couldnt find blue cross hairs, maybe by covering red and green lenses the blue will show on screen. anyway when done and cross hairs are clear,lenses, mirror and screen are clean, you can adjust covergence and get a very clear screencleaning will also brighten pic.

Blue color flowing from side and bottom into picture


Sony tech support (no charge) said it was definitely not the lamp.
Their suggestion- By unplugging the TV for a minute then turning back on, the blue color was substantially but not toally reduced.
Perhaps there is an electrical charge building up distoring the color by having the TV in the ready mode for too long and by unplugging, the charge dissipates?
No other phone solution recommended other than calling for repairs.

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .


Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!
