Unable to adjust the blue convergence to remove shadowing

The tv have a problem known as a convergence problems,it dead.Any colors lines R,G,B mis alignment,have 3D pictures or colors shadows.The tv convergence board it dead.Require changing 2 STK convergence ICS and some or all it resistors to solved convergence problems.The shop,will cost u $300-350 for parts and labors.

It means probably one of the two convergence ICs has blown

Ur tv have a convergence problems,it dead.The convergence board the 2 STK convergence ICS and some or all it resistors are dead.All these parts must be change to get ur convergence back to normal.The shop will u $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.

yes you need a new board

replace vertical IC and shadows/ghosting the problem is either electrolytic capcitor or video IC or convergence adjustment

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?

This would apear to be a convergence issue ..sometimes you can go into settings and converge it manualy.. if this is to far out of range. a service tech will have to adjust inservice mode. if the convergence cuircits are not failing. if so then there are cuircits that will have to be replaced. is this just a blue shadow?.. is there green or red shadows. if not it may not be a major repair.

my suggestion would be...to replace the focus block..john

You are going to need a full convergance alignment to rectify this issue.
