A very warm welcome to the HP community. A very good day to you.
I understand that you have an HP w2007 20 inch Diagonal LCD Monitor and the monitor does no thave any display. You tried to switch the cords and that did not help. Whenever you press a key on the monitor front panel, it goes to sleep. Not to worry, I'll do my best to help you.
To provide an accurate resolution, I need a few more details:
- This monitor supports VGA and DVI-D inputs. Which one are you presently using and have you tried both?
Also, I recommend you to perform the following steps to isolate the issue and arrive at a fix:
- Turn off the computer and the monitor.
- Disconnect the monitor completely from the computer.
- Power on the monitor only. If you get a display stating "no input signal" or "check video input", etc then it means that the monitor has passed the self test and is good.
- Please check if the monitor goes into sleep mode when you press any buttons on it. If yes then it is an issue with the monitor.
- Turn off the monitor and connect it to the computer.

I hope this information helps. Keep me posted Cheers! 🙂
