Auto convergence not working

The screen is all messed up. it seems as if the auto convergence on my Sony kp57hw40 is not working and there is no manual way to adjust this. Do you know what board is bad and needs to be changed? Any help would be appreciated. Thanks Jim

Re: Auto convergence not working

If its the color won't align its the convergence board. First you could look for bad resistors and or capacitors

I have a kp57hw40 sony tv and the scren it flashs

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Cannot converge colors on screen

This happens when convergence out ICs become defective.
Replace convergence ICs on D board to get correct picture. This qualified TV tech job.

My screen has gotten much darker

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Convergence problem

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow
