Westinghouse TV no picture : Strip or fix?

[JesusJones]

The screen is on

But still showing no picture. And its not really fuzz either. More grey than anything. Does it need to have an antenna connected. Or something in order to get picture. Or do I have more work to do?

ALso I am pretty lucky after warm up voltage at the horiz output tube is 150 -158 as stated by the schematic. So hopefully that works till I figure this whole. No picture thing out.


Could this possibly be a problem with worn or dead tubes??


Woooaaah. Just did another test watching from the back The tube in the bottom right v15 turned blue. But then went back to being fine. Should I worry about this? and would a gassy tube still check in fine on a tester?
