Hi

My picture has been a little blurry and I've cleaned the 3 lenses. In the instructions on changing the CRT fluid, he asks you look down each CRT while on with the color all the way down to determine whether the fluid needs changing.

Well the red and green look in focus when reading lettering in the video I was watching but blue is definitely out of focus. The fluid seems REALLY clear so I was wondering if there's a focus adjustment on or for the blue CRT itself?

THX!

Chris

That would be a really big direct-view set!
"KV" = direct view CRT - "KP" = Projection.
