The .1 in the grid circuit could cause a prob, but none of the ones I have ever worked on have been bad (leaky). I hesitated bring that one up for that reason AND the fact that its in a kinda busy area of the circuit board.
I am pretty sure he says he has checked those power resistors around the setup switch. one easy thing to check is to see if the plate voltage goes away from the 12By7 in the service mode. It should not, but if it does one of those resistors is bad.
Hopefully the problem will be resolved with as little need to remove parts as possible to test.
I am going to be making some videos later, and will be checking voltages both a the CRT pins and the video out.
