Dell E177FPc flat screen monitor

If its the standard type of small clicky on/off button( (usually a black dot with silver casing - but you cannot see that unless your screen is dismantled), and its no longer doing the click bit, it's probably just broken inside unfortunatly.

They are very much prone to breaking up inside. If the screen can be taken apart, you may be able to buy a new button off the internet, but they are often 'surface-mounted' buttons now, which makes them very small and hard to resolder to the board again.

If the button can be felt still making a click, you may be able to spray some cleaning spray (such as SERVISOL or WD40) into the switch, as they sometimes just get dirty inside.
(make sure its turned off before spraying anything like that tho as its all highly flammable).

If you are trying to detach the screen edging, they are usually secured by 2 or 4 screws on the rear (sometimes they may be hidden behind the actual base/stand). After that, usea large flat bladed screwdriver (or something like that), to seperate the front & rear casings. The reason for starting at the bottom is that if you slip or the casing is very awkward and starts to crack as you work out how it comes apart, the marks will be hidden from view later :)

Some of the casings click apart easily like this, but others can take some force, and may even snap the small plastic tags inside as it cracks open - but that it up to the fixer if you wish to take that chance. The screws holding it together are usually more than enough anyway.
