Somehow I have gotten my Dell 1701FP Flat panel monitor into a state where it will not allow me to use any of the control buttons on the front of the monitor. Whenever I press any of the buttons (except power which works fine) the monitor brings up a padlock icon and nothing else happens.
This is not the "OSD Lock" function mentioned in the instructions because if it were I could get out of it by pressing the Menu button and then minus. That should bring up the OSD Lock menu page, but it doesn't on my system, either buttons just brings up the Lock icon.
The controls worked fine when I got the monitor and it seems to have gotten into this mode when I had it face down (on a soft cloth) while changing monitor cables. It accidentally powered on and must have had some combination of buttons that caused it to get into this mode.
Any ideas how to get out of this mode so I can adjust it? Anyone know a way to reset the monitor (besides through the menu that I can't access)?
Well, I have the same problem, EXCEPT that... after I hold the "Menu" button down for 15 seconds and the unlocked padlock appears on the screen, I still cannot do nothing else. The symbol on screen changes back by itself to a "locked" padlock.
