Do all of the controls work on the convergence board? If not, part of the convergence board isn't running. If I recall, and I don't have the schematic in front of me, there are two picofuses on that board that protect the power supply from shorted STK modules. If not familiar with those, they're the size of a 1/2 watt resistor, and are usually black plastic. Those often open when the modules fail. (I could be of on that; the 4110 may have regular glass fuses on the board).
I have to congratulate you for the patience to change that glycerine fluid! That's a son-of-a-gun job, and it's nearly impossible to clean out all the fungus that grows in there. I tried once on a set that belonged to me, to replace the glycerine with water, and it didn't do so well. For customers, I mandated replacing the tube(s) if they had leaked or started to blossom with the fungus. Those were the first generation Sony projection tubes from the early 80s to the late 80s.
