Question about Panasonic PT-53WX54 53" Rear Projection HDTV

1 Answer

Can I fix my own IC's?

Red shadow appears 1/12 in to the left of allignment. Convergence adjustment with remote does not help nearly enough. We have no servie repairmen within 2 hours from us. Is is possible to repair the STK IC's, or Convergence board ourself? I'm smart, but never worked on a Projection television before...any valuable resources out there?

Sir the problem of your tv is the convergence to narrow the problem try to adjust first the convergence settings using your original remote go to setting menu then to the convergence setting, you can adjust the red and blue convergence, you should be able to adjust the red and blue left, right and up, down you should align the red and blue to green but if you cannot move them far enough or if you cant move them in any direction the convergence IC is already defective replacing this IC will fix the problem, you will find this convergence IC attach to a large aluminum plate this aluminum plate is the heat sink. It is easy to locate if you remove the back cover of your unit be sure to unplug your TV

this is the convergence IC if you remove this try to observe also if there is a cold solder or dry joint because sometimes this cause your convergence to malfunction observe the solder part of the convergence.

This is a cold solder or dry joints you can fix this by resoldering using a soldering iron, soldering lead, and desoldering pump but be sure not to connect separated pins it may cause much damage to unit if accidentally solder together. To replace the IC convergence try to check this link http://www.tvrepairkits.com/xcart/product.php?productid=19971&cat=1538&page=1 hope this helps good day and best regards.

My screen looks like its 3D.


Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

My hitachi tv's picture is distorted red and green like a 3-d pic


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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

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.

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 solution

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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

I get a ded line or red underline, or shadow that does not follow


3 d effect is most likely bad convergence Ic---think this set has in the customer menu an option to adjust--if it does go there----if red or blue will not adjust in any direction(up and down or left and right) you need to have both convergence Ic's replaced and then the set adjusted.

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.

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.

Is it my Convergance??


Do not try to align the colors with the remote. One of your convergence IC's has gone bad and needs to be replaced, possible burning one of the 3 low value resistors next to it. If you change the convergence settings now then they will have to be reset when the new IC is installed.
