Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television
I have a sony (KP57WS500)57" big screen TV. I have a pincushion pictures on my green beams and on the red and blue beams the pictures looks perfectly find. When the problem first started was a double line or double images on my screen, so I reset the Tv colors and flash focus(converge) that didn't help, so I took the tv back cover off and check the CRT beams and all of them are function than I cover the red and blue beams with a card board and I notice the green beams pictures are not straight at all. It looks like a bow(pincushion) on the top and bottom of the screen. When I checked on the blue and red beams the pictures are perfectly straight. Does any body know where to adjust this pincushion pictures or have any clue whats wrong with it? Any advice will help-Thanks....
Your convergence stick is going out, see ther is a set of two one that converges blue with green and the other with red to green cheak out you tube search how to fix your tv and look for convergence.

The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.
