Blue Convergence For about six months now my tv will have a blue shadow on everything for long periods of time. Once in a while I can fix it when I use the blue convergence function in the menu. I haven't been able to fix it for quite some time now and I was wondering if there is something that I can do to fix this problem so I can finally get rid of this blue shadow. Thanks so for much for any helpful suggestions..

Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

Tv have a problems known as a convergence problems it dead.Tv have colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board it is dead.The tv convergence board must require replacing 2 STK convergence ICS and some or all of it resistors too.To fix the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

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 projeciton 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 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. 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

CONVERGENCE 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 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.

You probably need to get a Sony TV Convergence Kit. More information can be found using the link below.

Convergence Symptoms:

• Screen Looks Distorted/3D
• Colors wont align
• Screen may look distorted
• No Audio/Video - makes a chirping sound.

If the blue shadow is convergence you should have an option for convergence adjustment via the remote control to converge the blue onto the green. If it doesnt move then its probaly a IC problem. What make and model set do you have?
