Question about Sony KP-51HW40 51" Rear Projection Television

Sony kp-51w5510 rear projection tv convergence

My friend gave me a big beautiful tv really cheap but it has a slight problem:the pattern of crosses lines up according to manufactures specs: two rows of crosses tight towards the top of the screen, and four evenly spaced rows across the rest of the screen. from there I have two problems. first, the ends of both sides seems to bend down. the second problem is the red cross is too far right to bring the three colors together using the remote control for adjustment. I run a union woodworking crew and have for ten years so I am mechanically inclined. (I think). I took the back off the set just to see if I could wrap my brain around it. I found that adjusting the focus of the three colors was quite simple. Loosen the wing nut, make slight turns and whallah. nice focused color. My problem is that I expected there to be a left and right adjustment for the red bulb that would jump out at me just as easily, and of course did not. Let me know if you can help, any advice would be greatly appreciated.

Take off the front speaker cover (2 screws) then take off the cover in the middle which has 4 screws. now you can see the 6 adjustment screws. the far left is the blue and middle is the green and right is the red.

Lateral red or blue movement is accomplished electronically
via convergence alignment circuitry controlled by STK type IC's
Replace them both for reliability, then adjustments will work..
