    Having a distroted picture at the top, middle and sometimes bottem of the screen. When I run the "Magic Focus" feature the blue and red look fine the green is distorted and fuzzy. Running the magic focus also seems to help the distrotion problem slightly but the top of the screen always has a focus distortion to it. Can someone help. I do not know the model number of the TV but it was puchased in 2002 and looks just like the 53UWX10B.

After having our tv in storage for aver a year, now it has a green shadow to it. What could be wrong/

Not sure I understand what you mean by green shadow. I would check the fluid in the green and blue CRTS and verify they are clear. I would do this if the green color seemed fuzzy or blotchy looking on the screen.

When looking on a blank screen, do you see any arc lines of either green, blue or red? If so, you would need to lower the screen voltage for that particular CRT.

TV issue

There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.

Pt-47wx49e convergence problem

I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Problem continued

Good Day;

When you activate the Mj focus the TV is restoring the data from the TV's digital circuits. So, you have the ability to change the IC's you can do this.

You need to go into the con service mode. Take off the front grill, remove panel, 6 - 8 screws. From the front there is a switch on the left hand side, it is small, white button with TV on. now you are in the service mode, using TV's remote adjust. Make sure you save dat. Go hit on line site get more info.

Goo0d Luck!
