Just remove the battery for 5 minutes. Disconnect any device (mouse, keyboard, modem, etc) except the monitor of course.
Also, disconnect the power cable from electricity (even if your computer is off, there could be some electricity going through so disconnect everything)
After 5 minutes. Put battery back on and power cable and turn on. After it turns on connect your mouse, keyboard, etc.
I've had this problem a couple of times before
and got it solved everytime by doing this.
Tell me if it worked.
