thanks for the help but the CRT board IS bad, the unit works fine with
a test one from a working set and the pix tube is fine.
I can't find what's bad on the crt board, except the 220 ohm risistor.

model number Q 2770 lack of red on the screen, replaced the crt board,

picture is still lacking red, & I ca't find any resistors open, or
leaky, or shorted diodes, or drive transistor. What could it be?
Thanks for your time, Robin.
