All of the pins of the CRT socket were not making contact when you first worked on the set. I've had a grid to fail to make contact on a 16 inch CRT and the only visible symptoms were a much longer spot and vertical retrace lines on the screen! These went away when the CRT socket was cleaned.
Some sets intentionally used a bleed resistor on one of the CRT grids to automatically bias the CRT to cut-off, immediately on shutoff, to prevent the spot showing, and the lower operating voltages may have been just enough to allow this feature to work again as it did when the set was new.

The coating on the Glass crt is still grounded to the chassis, and the high voltage cap is new to the set....so I will clean the crt connector.
The picture always shrunk down to a line first then the dot, now just the line and darkness..
just thinking that I did fiddle around with the crt socket while I was adding on the parts mentioned earlier......
