Monitor in question is Acer V223HQ, here are the specs:

It used to happen before, I would connect the power supply cable to the monitor and it would make that static hissing noise for just a second until the proper connection is made.

Yesterday I guess when I was moving stuff around, the cable got wedged and it lost perfect contact and made that noise again. I was somewhat used to this, but this time I couldn't find that sweet spot to connect it. It also appears to have burned something, as the smell was obvious.

I tried another cable, but to same result. Is it toasted or can I do something about it?
