Most likely you need 2 convergence IC's. Usually of the STK 392-xxx variety.

If you cannot converge the red and blue back to the green through the convergence menu, Then you have worn out convergence ICs you will need 2 of them at about 10.00 each. Takes about an hour to remove the old and replace with new ones, but also check the resistors right next to the ICs usually 1 or 2 of these burn out with the ICs. Let me know if you need more information.

The problem with my Phillips 9p6034 9102 with chasis number ptv 835 is that when you look at the screen straight on you can see the red green and blue lamps. When you stand up and look down at the screen...


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

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.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Covergence problem


your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.
