Still dark
I'm thinking its a blanking issue. CRT checks VERY good. I have focus voltage, screens are up, but not much brightness. The bias sw has little to no affect even in the service mode.
My Sams shows there should be +90 v on the blanker grid, but there is not. The plate has 130 plus or minus. On the very left inch or less of the screen I can see noise, the rest is black. What develops this +90 volts? Last edited by 6GH8cowboy; 08-10-2012 at 03:46 PM. Reason: wrong plate volts
