Hi


Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. Please check this picture:

There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

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

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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.

Convergence issue Blue not convering correctly, but the other colors do. The blue is warped at the top and bottom of the screen. Is this problem something that can be fixed?


Yes,the covergence ICs and precision resistors can be replaced to rebuild the area. A reputable shop may charge around $300 . If you are technical person,I can guide you further to do yourself!

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 have a convergence problem,all this sets show this problem sooner or later,you have 2 or 3 amps for the red,green blue colors and this amps go bad and need to be replaced then you have to do a convergence aligment from the service mode and not form the customer controls,a qualified tech should be able to correct the problem since is a common one.
