I tried it on the tester 7-8 v showing grid emission.

Won't be the same.
The TV has the cathode at 190v

Max is 200v
the tester won't go that high for sure.
and you can be sure that in the set that it DOES go over 200v before everything heats up anyway.
so IF the tube is shorting, there is a good chance that it is mixing AC heater voltage with the 190v bias.
and IF it's failing then AGC is not working the way it should be, making the tuner deaf.
