Dell Ultrasharp 2407WFP monitor button not responding
I have a Dell Ultrasharp 2407WFP monitor. The middle button that opens the Menu doesn't work. When I press it, nothing pops up - and in addition, I am not able to push the power off button after I press the menu button.
I have to pull the plug on the back to shut it off, and then I can put the power cord back in, and the power button works again. However, if I try to push the menu button again, nothing shows, and the power button is again nonoperational after this.
Any ideas why this may be happening? Thanks.
