Is the power button light on?

Customer: replied 1 year ago.

Yes. Nothing seems amiss!! Except the monitor is black.

Expert:  Dan replied 1 year ago.

Okay, power down the computer then unplug the power cord from the monitor and leave it for about a minute or better. Plug the monitor back in then power up the computer and let me know what happens.

Did as you instructed. No luck :(

How old is the monitor?

Customer: replied 1 year ago.
Two years !
Expert:  Dan replied 1 year ago.

Okay. I need you to try something but will need a flashlight to do it?

Customer: replied 1 year ago.

I think it must be difficult addressing all problems. I was trying to avoid going to the geek squad!

Expert:  Dan replied 1 year ago.

They most likely won't be able to do anything for you except charge you a diagnostic fee. If you have a flash light I may be able to tell you what the problem is.

I have a torch on my cell !! What are your thoughts?
Expert:  Dan replied 1 year ago.

If it is bright enough, hold it flush to the monitor screen and see if you can faintly see any of your desktop icons. You can even try moving the mouse to see if you can see the pointer move.

Black as a starless night :(
Expert:  Dan replied 1 year ago.

Okay. There should be a menu button on the monitor. Try pressing that to see if you can bring up the on screen menu.

Customer: replied 1 year ago.
No menu button. There is a wheel on bottom right that can dim or increase the lighting behind the monitor.
Expert:  Dan replied 1 year ago.

Can you give me the model number of the monitor please?

Customer: replied 1 year ago.
S271HL
Expert:  Dan replied 1 year ago.

It looks like the menu button is located on the base of the monitor. Can you check please.

Customer: replied 1 year ago.

Sorry. No button on base of monitor.....

Expert:  Dan replied 1 year ago.

Feel along the under side of the monitor on the right side.

Customer: replied 1 year ago.

There is a wheel. It dims and increases brightness of monitor. It hasn't worked for a while. I appreciate your efforts I need to call it a night !;
