First thing I see is diagonal lines in the pix. Also a grainy / snowy
background. Cure that first. Check the RF switch, cables & matching
transformer.
Also if you can take some pix of the set with real live people programing.
Its much easier to judge the TV that way.
Oh BTW with the Cromatic switch on ( red) you can not adjust the
color, tint, brite & contrast from the normal controls.
