Hello and thank you for your question, I look forward to assisting you today. Is this a computer monitor you are referring to?

Is the power button light on?

Ask Your Own TV Question
Customer reply replied 1 year ago

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

TV Technician: Dan, Broadcast Engineer 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.

Two years !
TV Technician: Dan, Broadcast Engineer replied 1 year ago

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

Customer reply replied 1 year ago

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

TV Technician: Dan, Broadcast Engineer 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?
TV Technician: Dan, Broadcast Engineer 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 :(
TV Technician: Dan, Broadcast Engineer 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.

Ask Your Own TV Question
Customer reply replied 1 year ago
No menu button. There is a wheel on bottom right that can dim or increase the lighting behind the monitor.
TV Technician: Dan, Broadcast Engineer replied 1 year ago

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

Customer reply replied 1 year ago

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

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

Customer reply 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 !;
