Thanks Kevin. I think I have a bad focus block or bad distribution block is
there any way to check them to see which is bad. I can turn the blue screen
control all the way down and tube goes out but the red and green stay lit .
Also when turning the controls all the controls adjust the brightness on all
the tubes. In other words when the green is turned the blue and red get
brighter. Don't think that's right but never had to fool with these before.
By the way turning the screens down stopped the flashing picture.

> Al, they are original diodes. I buy original diodes and transitors from
Zenith to make up my repair kits. Zenith sends transitors in egg crates and
diodes on long strings. Probably because of the quantity I buy at a time
they do not package them. If this helps here are common parts I use for this
board. Let me know if I can help
