Seems to be no video at all. G-2 OK.
Cathodes are at VCC voltage so no raster. Now it depends on where the video comes in. Usually its to the RGB outputs emiters. Sometimes in the
jungle IC.
With AKB you can look at the CRT condition. Each output & K is fed by
about a 27K 2 W Ground the collector with a same value resistor. ,
one C at a time. Should get nice brite color for that gun.
Mucky dim color is usually the CRT.
& remember the lower the K voltage the briter the pix.
