I have recently set up a Sony VPH-1271. I'm confused as to why my green tube shows lines brighter horizontally than vertically. (See attached photo)
Because of this, when I display a properly converged cross-hatch pattern, vertical lines have a red tint, while the horizontal lines of the cross hatch pattern are proper, balanced white.
I have adjusted the "screen controls " and the electronic focus controls. It seems the vertical line stays 1/2 the width of the horizontal line. This only happens on the green tube. Using the screen controls I try to get the vertical line to be brighter but the horizontal line blooms too much.
I have heard about adjusting magnets on the CRT neck - would this help my problem - perhaps something came loose while I was moving it?
The projector has 9K hours - if this makes any difference.
Any help would be greatly appreciated.
