I don't think you'll be able to see the bowl properly. These problems are usually due to blown convergence ICs, which need replacement, along with perhaps some resistors and a check of the entire convergence board.

    Sometimes the TV will "click" back into convergence if you leave it on for a while (if it does this don't turn it off until after the Superbowl), however, it will go out again and will need repair and it's better to repair it sooner than later.

Blue line Ghost Image on Panasonic Projection TV

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

I have a Panasonic PT-53WX54J that will not Converge


you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

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

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

Convergence images?


The blue picture tube of a projection tv is usually the weakest in ability to focus and in most cases loses its focus ablility before the red and green. Connect a cross-hatch generator to the rf inputs of the unit and check to see which areas are most out of convergence. The corners are usually the worst. HD will always bring out the slightest imperfections. If the unit was totally out of convergence, I would have suggested replacing the convergence IC'S.In my experience with rear projection, your problem is normal wear . You could conceivably improve the picture by adjusting the blue focus on the screen focus block. Scrivitron
