We have a PT-47WX51CE panasonic cinemavision hdtv 1080i and the colour is off. We see separated mainly green and magenta and the picture is warped with some lines.


Hi,
All that mess in picture is due to failure of convergence output chips in this tv.
Replace convergence output ICs (two ICs) to solve picture problem. Required ICs are available in Part Store, click the link to have price info.
Thanks.

Panasonic pt-47wx53g red is out of convergence range


Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

Red and blue ghosting,


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
