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?
