If it looks a lot better its the CRT 99%.

All fixes are risky ( except a new CRT )
Rejuvenation, only use a MODERN CRT checker for this made
after the early 70's.
Brighteners only work on some sets.
Most sets have a low ohm resistor in series with the filament.
It can be jumped out to give a little more E but again risky.

As far as waking it up goes regular use will usually improve things
but its a process that goes on just like people getting old &
slowing down......

OK, I'll give the TV a try and see if it actually exibits any of the symptoms you mentioned or if perhaps its just needs time to wake up the CRT from not being used for a long time, seeing as this TV is from between 1967-1972 I would guess that this TV probably was supplanted by a modern Color TV and was just left in a guest bedroom for years unused, before the previous owners donated the TV to Goodwill.
