Taking the six underside screws out reveals this board. But switch board is still a bit underneath. Having problems posting more than one photo at a time.

Repair went nicely. I must have had same type of switches Phil did as I had to cut two of the ends off and mount it diagonal. Taking out four screws lets this piece remove so you have some additional room to work.

Now that that is repaired I wanted to test my B&K 1246 color generator I purchased on eBay more than a year ago. These Sony KV-4000 sets have solder pads that you either remove solder at one place or add it at another place on the B board to do vertical and horizontal Centering. My horizontal is slightly to the left of horizontal center. I'll try the adjustment called out in the manual.

Here is a close up of the B board with a toothpick end showing where the solder pad that you short to move the horizontal centering more to the right. The one directly underneath it you can see is already shorted. This would be the pad pairs that center it more to the left of horizontal center.

Set has slight overscan, which I believe was somewhat common. I wish the adjustment had moved it a little more to the right side. But overall I think I'm done. My avatar is this set on color bars after the centering. Here is crosshatch pattern after all my adjustments. Unfortunately there are no pin cushion or barrel adjustments on this set. This is already quite compact and Sony probably made some circuit cuts where they had to for space.

Did this all on the dining room table. Glad I bought the manual when I worked at the shop. I bought a lot of Sony gear and always made a point to also purchase a manual. Here's a shot of my limited workspace last night.
