Monitor flickering on and off rapidly

Pavillion 27xw
My monitor (which is on auto-turn off mode) will flicker on and off rapidly the second its connected to power without responding to the power button. It doesnt matter if its connected to anything via HDMI or not. I can’t tell if this is a problem with the monitor itself or with a possibly corrupted power cord. Im unable to adjust any settings because I literally cannot turn the monitor on.

How new is the monitor -- is the original HP Warranty still active? If so, contact HP, to get repair/replacement.

 

Can you take a MultiMeter, and measure the voltage & wattage produced by the power adapter?

 

Maybe, replace the power-adapter, via eBay
