Most likely convergence amp problem?

I have a pt47wx49e panasonic 47" projection and the left side is beyond convergence adjustment. there is slight bowing color shadows. from what ive read, it sounds like the amps are out. also if i can replace them with a better alternative which part number should i order? on a seperate note, is there anything i can do while i have it open to get a richer contrast as i am experiencing a bit of washout but the screen has no burn in issues. thanks in advance.

THE PICTURE ON MY TV IS SHOWING A YELLOW SHADOW ON ON SIDE MORE & A BLUE SHADOW ON THE OTHER. IS THIS A BULB PROBLEM?


TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

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.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

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
