In the meantime .Yesterday I poked around in the Sony set.I'm questioning the CRT since its dim .low brightness .heater is lit .The other question is why there is only 3 wires going to the CRT socket PC board in which is very odd to see.Heater B+ which read 12V and probably the cathode. That was reading low volts. What happen to the grid wires? Didn't see any broken wires from it laying around on the PC board.I think somebody else was in this set and screwed around with it before I cracked it open.After seeing that going on .Maybe the CRT is OK....
