Sony KP-51HW40 Convergence issue

I am trying to determine the best solution to my problem with a convergence issue. when powered on the convergence is way out of whack. I can go into service mode to fix it but if it ever gets turned off, I have to go back in and manually make the adjustments to the whole screen and all the colors. I have heard that replacing the D-Board can be a simple fix for for a non-certified tech type. Are there others for a non-professional?

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.

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.

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
