My computer monitor has been acting strange recently. The monitor menu is repeatedly coming up by its self and increasing the contrast. The brand is NEC AccuSyc LCD52V. Any ideas on what is going on?

 

Could the button be stuck or perhaps the contacts dirty?

 

No, I don't think that is the problem. Also, when menu comes up, all buttons on monitor (including the power button) are sometimes unresponsive. Can any body clue me in on what is going on?

It sounds like the monitor thinks buttons are being pressed. It could be corrosion on the PCB, especially if it uses conductive rubber switches.

I would inspect the PCB with the switches and the connections to it.

Maybe there is a reset function too -- I didn't check.
