KG251Q Monitor buttons pressing themselves

Title basically.
randomly started last night, the menu opens and just keeps going down for about a couple of minutes or so. until it eventually stops and then disappears. Only to come back to rinse and repeat about 1-2 minutes later. I have tried checking the buttons to see if anything is stuck, resetting the monitor to factory settings, unplugging all the cables and holding the power button for a minute, which has made it a lot less common now (about 10-15 minutes instead). But yeah it's still doing it so any ideas on how to fix it would be great.

Thanks
