I have a Gateway computer. What I’m experiencing now is that when the computer either goes on standby or it is turned off, when I turn it back on the monitor has the green light on but no picture. Then I unplug the power cord from the back of the monitor and plug it back on then the monitor starts blinking either with a dark grey color or sometimes is with by desktop images but it wont stay on. So I keep on doing that for a while until eventually it stays on. Could it be the power cord?
