Green rainbow streak on bottom of TV PT-47Wx49E

Seing a green rainbow streak on bottom of TV PT-47Wx49E . showing duplicate text as if the color has folded. Convergence on setup dosen't work.

Where do i start ? dosent seem as a convergence issue. Could it be the open resistors talked about in this thread. Don't have a service manual or location ifo to examine the resistors.

TIA, Sunny

    i do not understand your ways of fixing this problem?

  • Anonymous Dec 10, 2008

    Hi I had the same problem. If its the green thats off, you're going to need an expert if you don't feel comfortable digging into the back of the unit. In my case two soddering point gave up, causing tow resistors to go bad. the upshot is $350 In repairs to have the unit fixed, and re-tuned to set the green convergence correctly. If you want the manual you can get a free manual from the panasonic service site. just do a search on your model number. good luck

If Convergence on setup dosen't work, And you think its not STK Convergence chips!, Then "Yes" It more then likely will have a few open Resistors!... (Near STK chips)

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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Red horizontal convergence PT-47WX49E


converge outputs getting tired or limiting resistors opening up. adjusting this incorrectly will make the situation worse keep in mind that overdriving these chips will cause a fold over of your image when you see this carefully adjust in the opisite direction as you may be overheating the outputs

Blue line trouble


Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps
