Presumably the power supplies have been confirmed good prior to anything else being done.

Hello Dan,
My recently bought 8560E has the same issue. Intensity is at maximum (255). Graticule is a bit dim too. At first I thought it might be the many Elapsed Hours (8869), but I cannot see burning-in effects. I did shift the image up and down, but no effect. So that looks good. I will try to get inside and find the monitor brightnes/bias pot. Must be there I think. I do have the service manual with CLIP from Artek but I still have to have a look at it.
Did you already investigate further?
