High deflection zenith

[josephdaniel]

well after getting it set up properly after having hundreds of people turning the knobs on it every witch way I finally got it working picture is not very sharp and when showing a program that fills the screen the picture at the top bends to the left. I have already cleaned all of the pots so I don't really know what to do from here...
p.s. anyone know the model? apparently it got rained on and all of the labels fell off...
