I had the same kind of problem with my AOC monitor.
Since my warrenty is long over I was willing to try to disconnect the faul button, and it worked! Here's how:

First, try to understand which button is the defective one. It seems as if one of them is permanently pressed - in my case, the one that was used to bring on the OSD and scroll through it.

IMPORTANT: disconnect the monitor's power line.

Use a screwdriver to open the monitor's back pannel. I can't guide you here, it really depands on the type of model you have. Make your way to a small PCB located just behind the buttons, and gentlly take it out. it should be still connected to the main board with a bundle of small wiers.

On that PCB, locate the microswitch related to the defective button. If you have what it takes, replace that microswitch. If you don't, like me, follow the next steps:

On the green side of the PCB, opposite to the microswitch side, you'll have to follow the lines leading from the microswitch to that bundels of wiers. There are 2 lines going that way, one of them is "common" - that means it converges with all other lines comming from the rest of the microswitches. What you're after, is the other line. following it all the way, you'll see exactly which wire is connected to it. Dubble check that.
Take a deep breath, and gently pull that wire out of its connector.
Put the PCB back in place, close the back pannel and plug in the power line.

This solved the problem in my case. Yes, you will not be able to bring the OSD on without taking the minitor apart again and reattaching the wire, but how offten do you use the OSD anyway?

Locking OSD settings
When the OSD is locked, settings cannot be changed in the OSD menu. The OSD functionality is enabled or disabled by pressing the Menu button and holding it for 10 seconds. Upon disabling the OSD, an OSD Lock-out message is displayed for 10 seconds. When the OSD is locked and an OSD menu button is pressed, the OSD Lock-out message is displayed for an additional 10 seconds. When the OSD is locked, pressing the OSD menu button for 10 seconds unlocks the OSD and displays the main menu. Identifying monitor conditions
Special messages display on the monitor screen for the following monitor conditions:
  • Input Signal Out of Range : Indicates the monitor does not support the input signal because the resolution and/or refresh rate are set higher than the monitor supports. Recommended refresh rates are as follows:
    • For the w1858 monitor: 1366 x 768 @ 60 Hz.
    • For the w2338h monitor: 1920 x 1080 @ 60 Hz.
  • Monitor Going to Sleep : Indicates the screen display is entering a sleep mode.
  • Check Video Cable : Indicates a video input cable is not properly connected to the computer or monitor.
  • OSD Lock-out : When the OSD is locked, the warning message OSD Lock displays for 10 seconds.
  • No Input Signal : Indicates the monitor is not receiving a video signal from the computer on the monitor video input connector. Check whether the computer or input signal source is off or in the power-save mode.
  • Auto Adjustment in Progress : Indicates the auto-adjustment function is active and in process.

This is from the user manual for the monitor. You can download a copy from hp here:

Click on the "monitor user's guide" link to download.

There are four adjustable options on the OSD settings screen: Lock OSD settings, Timeout, H Position, and V Position.
To change OSD settings:
1 Open the OSD setting screen under the Advanced menu. See
“Using the On Screen Display” on page 25.
2 Press the Browse buttons to select the option you want to adjust.
3 Press the Select button to check the option.
To change OSD lock setting:
1 Press the Browse button to select yes (lock) or no (unlock). The
setting is automatically saved when you change the value.
2 Choose Exit sub-menu and press the Select button to return to
the OSD Main Menu or press the Menu button to exit OSD.
NOTE: Once OSD is locked, all OSD functions including the
shortcut buttons are disabled. If OSD is locked, pressing
any button on the monitor directly opens the Lock OSD
settings window so that you can unlock OSD.

Osd main controls locked/unlocked pops up every 5 seconds


Press the Menu button ( marked OK) for one minute, or more, and a blue/red menu list should appear on screen.

Using the adjust button (immediately to the left of the OK button) by pressing the arrows at each end up or down as required you can enter the menu and select an action by scrolling.

At the end of the list of possible adjustments on the left of the screen (brightness, contrast, etc) is the Reset section.

On the righthand side of the screen is a flashing Yes No choice which automatically alternates.

The trick is to select the Reset choice on the left and while selected press the OK button when the Yes alternative on the right of the screen is flashing.

You VDU should then Reset and all will be well.
