Red and Blue slightly out of alignment


If constant all over the screen it is the static convergence that needs adjusting.
The green is not adjustable!
Move the red magnets with the blue covered with a piece of card to align with the green and then move the blue with the red covered to align with the green.

Ghosting in Red, Green and blue


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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. This is called convergence.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

You are on the right track. The problem is actually with the green convergence IC that controls the alignment. The convergence ic's take the information from the 3 pictures and align them into one picture on the back of your screen. Although this is an economical repair it is complicated and should be left to a quailfied service technician. If you are not sure of a local technician, panasonic's website has a servicer locator that can guide you to one. Hope this helps
