Question about Panasonic PT-47WX42 47" Rear Projection Television

Projection Tv Problem

I have a 3 year old projection tv. I just started having problems with it last night when it started showing a double image. The red is also way off center. What can I do to fix it?? Please help!! The picture on my Panasonic PT-47WX42 Rear Projection HDTV has a horizontal wave of distortion which seems to be the most pronounced at the top and bottom extremities of the screen, but is visable throughout. The colors are improperly alligned, and the convergence adjustments described in the manual do not seem to have any effect on the problem. This problem did not develop gradually. I turned the tv off with everything working as usual, and turned it back on to find this. I removed the screws that hold the screen to the main body of the unit, but the bottom edge seems to be secured beneath the plastic valance where the front AV connections are located, which in turn seems to be secured beneath the speaker dust jacket. I find no visable fasteners keeping the valance or the dust jacket in place, and I dont want to break anything by guessing incorrectly which way to yank or twist or pry, so thats as far as my repair attempt has gotten.

    Sounds like the same problem i am having. i only have the wave at the bottom with color distortion. i talked to the store from where i purchased the tv and they told me it sounded like a crt gun. they recommended replacing all three guns. the tv is 4 yrs old. is this a common problem with these tvs and is it worth fixing.

The problem you are seeing is a convergence problem. This is a common problem and is fixed either by resoldering bad connections on the convergence ICs or replacing the ICs. These are large black ICs attached to a heatsink and are marked STKxxx. Try resoldering the pins on these ICs first.

The old projector TV's are using 3 lamps for Red Green Blue....in your case the Green lamp stopped working....either the Green lamp burned or the lamp board is defective.

Tv shows double images


This is a problem within the convergence circuit. If you can solder you should be able to repair this yourself. Let me know if you wish to attempt the repair and I'll provide additional details and instructions.

I have a Panasonic HDTV Projection PT-47WX42 with double imaging.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

Double image on letters for progran guide, 12" green line during perfect focus and on start up componet one need to be re-booted a few times to acquire video


Best advice run as fast as you can to the nearest Repair Shop that does samsung warranty- /// quit calling circuit city it seems like they could care less if your set is fixed or not bad business,first of all those double images you are seeing means you have convergence going out repair cost with out warranty is 350.00 and up to as much as 560.00

Im seeing double on my 36inch Mitsubishi projection!


Do the colors seem "separated" somehow?  Sounds like the projectors might have become misaligned. Has the TV been knocked by pets/children/spouse?

Projection Tv Problem


some of these tvs have internal adjustments for everything including alignment which fixes the double image problem. if you remove the cover you will find a lot of little adjustment dials. you may find that they have symbols that show what the adjustment is for. if you want more info. email me at sb1216us@yahoo.com
