Panasonic PT-47wx49 color distortion

The colors have seemed to have separated (ie. blue, red, green. images are "ghosty". I bought it in 2002 and am wondering if the bulbs just need to be replaced, and if so, how easy(pricey) is this to do.

    same problem, but mine is a PT-47WX53G 42 in.



    Is it difficult to fix? E.g. part not available, difficult to reach inside TV, extensive test?

1) Replace both convergence IC's...located on large heatsinks
STK392-110 use Pana,Toshiba,Philips or upgrade to my
choice.....Hitachi ( Mfr'd by SANYO ) Part # CZ 01341....

2) Check 2.2 ohm 2W B+ feed resistors for over-heating....

Note: Requires chassis pull..technical & soldering ability a must.

The color goes out on my panasonic PT-47WX49E TV.


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

I have a panasonic pt-60dl54, the sound works but green picture


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.You will need to replace the DMD board. Have a blessed one!

Setting Color on TV


Hi Amber3,

I would recommend reading the information available on Panasonic's website. There are links for Frequently Asked Questions (FAQ) which may be helpful.

The manufacturer's website lists in their FAQ the Panasonic plasma TVs include an enhancement feature for blue and green colors, and instructs how to turn the feature off if needed. Visit http://www2.panasonic.com/webapp/wcs/stores/servlet/vSupportFAQDetails?idval=UCM_PRD_CNT_001993&pagetitle=FAQs+for+Plasma+TVs&contentType=FAQ#tv17 to see what Panasonic recommends.

Thank you,
Jason,

Panasonic Model No. PT-47WX42F


Replace the convergence amps. That unit takes two Sanyo STK392-110 and you could use 150's for greater reliability. Also replace one or more of the 1.2 ohm resistors in the yoke return circuit out front of the amps.
