Zenith 20Y1C50 broken again
Yesterday, I decided to put the original picture tube back in my 1968 Zenith 20Y1C50 set, and everything went perfectly. Not a single headache, and I had the thing back up and running in an hour, and only half an hour to do purity and convergence. So I get up this morning, and it still works, but when I go to adjust the brightness, the act of simply touching the brightness control kills the luminance. There is very little luminance/brightness. Almost like the potentiometer is stuck at 1/4 of the way up. Again, it was working perfectly when I put it back together yesterday.
