Is it the round button kind or the long thin kind? I broke the long thin power button on my viewsonic vx924 since I would push it down instead of push it in in. It is difficult to the break the power button though unless if it were pried out since that is one of the most durable parts on on the monitor. I use a power strip on it now since the power button is stuck on the 'on' position however it seems like that yours is stuck on the 'off' position but you do have access to the interface below. Best of luck.
