Question about Dell E171FPb 17" Flat Panel LCD Monitor

3 Answers

Padlock appears on screen

I was out of town for 6 weeks and when I returned, my Dell e171fpb monitor now has a padlock that appears on the center of the screen. I tried to access the OSD menu, but none of the buttons on the front of the monitor work, other than the power button - any suggestions? I've unplugged it, held in the menu button for 15 seconds and I also tried changing the resolution setting from the control panel (these were suggestions that I found on the dell web site) but they did nothing. Thanks!

Hold the menu button until the padlock unlocks, it takes anywhere from 30 seconds or even a minute or so

I simply unplugged the screen from the PC (NOT the power cord), waited a minute, then reconnected it. Hey Presto the blue thingy was gone and I could fully use the adjustment buttons.

Padlock icon

Many monitors have an on-screen display lock (the padlock icon) that seems to get stuck.
Various suggestions in the links below - the one that seems to work most often is to hold the monitor's menu button down for 15-20 seconds to get the screen menu, then either try unlocking the OSD (On Screen Display) or do a factory reset on the monitor.
Different monitors have slightly different menus, but if it's a Dell monitor you can find the manual below (under Display):

After my computer has booted up, I sometimes get a graphic of a padlock in the locked position on the screen and can't get rid of it -- what do you suggest I do to fix this problem?

Try pressing and holding the menu button on your monitor for 15 seconds or until the padlock graphic changes to an unlock graphic. Hope this helps you.

I have a blinking padlock in the middle of my monitor screen. What's wrong?

I'm not sure of the exact cause of this issue but I've heard of similar problems being caused by your desktop resolution being out of sync with the resolution of your monitor.

I've read elsewhere that the problem has been fixed by Right clicking on your desktop, going to Properties & adjusting your screen resolution to something different, clicking apply...then adjusting it back to whatever you'd like.

Failing that, I'd suggest giving Dell customer support a call. They have access to a lot more diagnostic material including button combinations that may clear the error out.

You can log a ticket online with them, or call them directly. The number can be found on

Padlock appears on screen

I have this monitor,got it used at the goodwill, padlock problem and the control buttons (eccept for power) did not work. I tried every solution posted with no success. Then I got brave, I dove into the problem. 1) remove base, four phillips head screws. 2) remove the back, five phillips head screws. one in each corner and one behind the base mount, thus the need to remove the base. 3) carefully pry off the back, it snaps on, so take your time. I found a butter knife to be very helpfull. 4) The buttons are sodered to an electrical board whitch is snapped into place so carefully pry up from one side,again I used a butter knife. The wires are sodered to the board, they do not unplug. 5) Using a can of air, blow into each button and trying to clean out the inside them. I'm sure they should probably be replaced but we do what we can. 6) Put it all back together. 7) plug it in and connect it to computer. start working the buttons, at first I thought it was a lost cause but after about a minute I was able to get into the menue, scroll down using the arrow buttons and turn the lock off. A $300 monitor for 40 bucks. I hope this message gets to you before you give up. GOOD LUCK, GMAN8773

Flashing padlock icon in the middle of the screen

When the icon is in the unlock position, hold down the Menu key (the far left button in the lower righht hand corner) on your monitor. This should bring up the menu. From there, you can reset the factory settings.

Dell e171fpb lcd monitor

The driver tabs between the LCD panel and it's controller board have failed.
These are very fragile and not repairable for anything in the cost effective range.
Best option is to either find a new panel to replace it, or get a new monitor.
