HP 22er Monitor Display not working

[rayancaleb]

Hi,

When the power cable is plugged in, the small light next to the cable turns on implying that the monitor is getting power. However when I press the on button, nothing happens. If i plug my HDMI cable into the monitor whilst connected to my laptop, my laptop recognises the display as being on yet nothing happens as the display remains completely black. (With still no light by on button)

I have tried holding the power button for 10 secs to 'unlock' it but that has not worked?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
