I've got a Dell E171FP, which has decided that none of the buttons want to work when pressed. In addition to this, I have a giant padlock in the middle of my screen (infact, how I am posting this from a PC connected to said monitor is nothing short of amazing)

Suspected cause is a power surge, as it killed a PSU in the attached rig.

Is there a way I can hard-reset the monitor to see if this fixes the issue?

This happens with the U2311H actually every now an then. Solution:
  1. Shut down your system completely
  2. Pull the monitor power and video cable
  3. Hold the power button on the monitor for 5 seconds [discharge the caps]
  4. Reconnect the power and video cables
  5. Power on your system entirely
Once you hit your desktop, hold in the button above the power button for 10-15 seconds and it'll unlock [the little padlock will change from closed to open].

This is how I was told by Dell's CS to do it and it's never failed. It just seems to be a power regulation bug I guess. It isn't a huge hassle really

There is no button above the power button, so I held each button on the unit for 10-15 seconds. I have got it unlocked but the menu is now stuck on screen. So I held the brightness/contrast button for 15 seconds and it worked

However, none of the buttons on the front of the unit function any more.
