Hello, i have a Dell E770s with an intermittent green gun. The problem
is in the monitor itself because the built-in testpattern shows no
green, just red, blue and black where green is suppsed to be. I have
resoldered almost everything leading to the green gun and has not
improved the condition. The problem is usually when its cold, but i
have seen it stay that way for hours before it returned to normal. Any
suggestions on what to replace or check? Could the driver be
intermittent or does it usually just "go"? Thanks in advance.
