Question HP Envy 34c Media Display - OSD/buttons issue

[Greenston]

Hi there,

I have an ultra-wide monitor, the HP Envy 34c Media Display, which has worked fine for years but suddenly it started acting funny.
The reason I post my question here is because my Google searches have turned out empty and I'm reluctant to open it up and check the hardware inside.

The funny thing is I don't have an issue with the display itself, that still works. But the problem is I can't control the monitor anymore through the OSD.
To be precise, I can't get the monitor to show the OSD at all. Every external button I press (Volume up, volume down, power button, menu button, ...) all just mute or unmute the built-in speakers. I know this because the mute/unmute icon displays every time I press a button.
The remote that comes with it also has the same issue, every button does the same thing: mute/unmute.

I made the conclusion that this had to be a software issue so I installed/reinstalled the latest drivers for both the monitor and GPU.
I also did a clean windows install to be sure. But nothing worked.

Could this be a hardware issue?

Thanks in advance for any advice.

KR,

Nevermind, I found the problem. I'll explain my fix for anyone else who might be faced with the same problem (highly doubt it, but just in case... ).
The problem was the radial volume button on the bottom left of the monitor. Apparently some dust and goop got stuck in it and created a bad contact overriding every other action.
I cleaned it out, problem solved.

Thanks.
