If you are struggling with a Sony Vaio desktop computer monitor that displays a 1″ x 3″ gray box in the very center of your screen, it is from the malfuncioning Menu buttons. Figure out which button can turn off the message box, albeit for five seconds. Once you clear the message from the screen using the monitor menu button, place something under the button to keep it depressed while the monitor rests on it. This way, the message is prevented from popping up again. You can also try taping the button in the “pressed” position. Finally, relief.
