The monitor on/ off button is stuck if it is not turning off. This will cause all kinds of issues including scrolling menus and the like. It is a physical problem. Depending on the model, you will literally have to place something underneath the power button ( central blue if lit on my model) to unstuck it thus releasing the screen message or scrolling issues. Believe it or not I used a butter knife at first until I found something I could use to hold the On/Off button tilted slightly back from underneath. Only thing I could find that worked. Find something thin to replace what I used that accomplishes the same thing. Button pushed back and slightly raised. Hope that helps. On actual depress buttons (towards the monitor) obviously this will not be the solution.
