Usually answered in minutes!
The other set of three dials on the focus block are only dummy dials or blanks.
The dials are located directly on the CRT, and all three CRT dials turn but there is no response or change.
Yes, this is true. But the three marked for the screen are blanks! The dials are directly on the CRT boards, and this dials do not respond.
Red is dim, and does not respond. Green and blue do not either, this is probably because they run in series with Red being the first in the series.
Is there a possibility that something on the Red CRT board went bad? And can this be fixed, cheap.
