I can't find much info on the 960 series, but if it's anything like the 800 series you'll have to completely remove the tube from the support frame. There's the deguase coil, etc. that you will have to pull away and so on. Although don't let this discourage you. Fixing one of these sets is probably the most rewarding experiences you'll have in your life. Take it slowly and note your steps and you'll be fine. I made a mess of my 800 series D board repair and haven't looked back.
