For a couple weeks now, I've been having issues with my old Dell monitor (purchased back in 2004). For reasons unknown, the settings menu keeps on popping up on its own. I am able to exit out of it after one or more presses of the "Exit" button on the front of the monitor, but the monitor keeps on reappearing.

I suspect this is a purely mechanical issue, but what are my options, beyond buying a new monitor?

This symptom is usually due to leakage in the control button PCB. Are the buttons located low on the front bezel under the screen? In this location sometimes liquid from screen cleaning can have oozed down onto the board or into the little button switches and left a conductive corrosion. Sometimes one of the buttons develops internal leakage that makes it look like it's being pressed, and one Philips monitor I repaired had some clear liquid that didn't evaporate located beneath only one button - no indication where it came from...

Would you consider opening the case an option? Cleaning off the control board with alcohol is something that can be tried without need for any real technical expertise, but if one of the buttons has gone leaky, it would need to be replaced.
