The anode lead on the FBT will push & turn to remove, but probably at the HVR block (not at the top of the FBT.) The focus wire should also unplug, but again, probably at the other end. Pull the rubber boot back, and carefully push and twist about 1/8 of a turn to the left. It should come out. If not, try the other end of the wire. When reinstalling, just push & click... no twist needed.
Also a note about soldering on those newer boards: Be careful when unsoldering not to burn the foil off. It's easy to do, even with a lot of experience! Use a vacuum to get as much as you can off, then use wick for the rest. It takes a lot of patience, which is one reason that the shops charge that much. I always charged a flat $150 + parts for any convergence chip job that I did under contract for TV repair shops that I worked for. And that was without having to pay rent and insurance on my own shop. If somebody will do it for $275, you might want to think about that... Remember that you may also need more troubleshooting, and then the ALIGNMENT
. However, you CAN do it yourself if you're somewhat experienced with PC soldering.
