I am facing the same problem too, did you find the solution
I am using Dell E171FPb Flat Panel Monitor
A flashing lock-unlock symbol appears on the screen all the times
Blue color reverse (white) padlock in the cente of the screen
I am facing the same problem
Blue color lock-unlock symbol in the center of the screen
I tried all the buttons, nothing happens
Dimension 2400 series
Dell E171FPb Flat Panel Monitor
Buttons on the monitor not responding
Did this ever get figured out? I have the same problem - flashing blue/white padlock (locked/unlocked) and none of the monitor buttons work in any combination for any amount of time held down.....
Did anyone sort this out
I also have a E171FPb monitor where the only button to work is the power button. It also has the padlock (white on blue background) which cycles between lock and unlock with the occasional period when it just plainly disappears. however just when I think it's sorted it reappears
This monitor does not have volume. Ive tried 30s plus of menu plus every other button including power
I did once get the OSD up by turning monitor off and then holding the menu button down when powering up. but then could not select anything from the OSD. I cannot repeat this however
HELP why throw away a otherwise working monitor?
Hi,I am facing same problem on U2410F monitor, a lock icon shown on the center of the screen, buttons can't work except power button.
Hope your help, thank you!

On the Dell P2312H you hold the button above the power button down for 15 seconds.
