You cant realign them they are factory set so you would need to replace them if the colors are out of line or you cant reset it manually. the tube are preset and not meant to be redajusted

KB-51HW40 blur with different colors layers


Its called the Convergence. Its likely a device on one of the main control boards is failing. these are a common issue on the projector tv's usualy it will be a whole board replacment, OR componnt level trace and replace. This is something unless you are familiar doing can be quite hazardous. If your not sure get a local shop to give a free estimate, all my projection tv's have done this with time, you can even go into the menus and realign it through tv settings, but sometimes they will start to wander out again.

Below is exploded view of your Sony KP-51HW40 TV rear side which shows board names and location.
You need to check D Board for convergence ICs and these are marked as IC8001 & IC8002 on circuit board.

Sorry about that heres the link. No installing the board will not involve soldering if you decide to go that route.

Sony KP-51HW40 Convergence issue


Can you adjust the convergence by the convergence menu without going through the service menu? The settings through the convergence menu should save automatically. Have you replaced the convergence ICs? If so the settings should save, if not the D board will need to be replaced or at the very least rebuilt. Let me know if you need further assistance with this issue.

Sony tv KP-61HS10 lenses wont align


This is common in those sets. One of your convergence IC's has stopped working and needs to be replaced. The convergence IC should be replaced and the convergence circuits realigned by someone with experience in Sony projection sets.

KP-51HW40 - Picture not Clear


Your problem is a typical convergence problem that happens on almost every tube type projection TV set ever built. There are two Convergence amp IC's that need to be replaced. If you have no TV repair experience, play it safe and call in a pro to assist you in this. Good Luck

I read it online that this is a very simple problem. It needs highvoltage splitter. I tried to open the front panel to see where the splitter is. However, I need some hint as to how to open the front panel. Good luck. Kiran
