the monitor is bad
if it will not power on,
or show NOSIG< with XBOX on then turned off the monitor must show NOSIG>
why not test the monitor on any pc made even laptops VGA jacks works, so that works, its not the monitor.
and bad xbox video caused. but is not it. as you said.
the menu needs sync lines active. to pops the OSD button menu.
so the monitor is bad.

or the cable.

what is w2007, lets see.?

this old monitor runs CCFL lamps.]
im shocked it glows at all up to now.

HP W2007
users guide last page.
This HP product contains mercury in the fluorescent lamp
in the display LCD that might
require special handling at
end-of-life:

that means CCFL died, also all do, soon.
(as short as 2 years, full time , they die. 20k hours)
out of your service manual it shows.
what any running pc connected the OSD menu most work
not in sleep mode.
if there is sinc, H/V pins active
that OSD must work or the blacklamp is dead
use flashlight see, there is data there, see?

Check that the data cable of the monitor is properly connected to the back of the monitor and the desktop computer.
If it is properly connected, then most likely a component within your monitor has failed and will have to be replaced. If you have another monitor that you can connect to the computer to compare, you can confirm that the problem is indeed with the monitor and not with the computer itself.

From my experience, it probably means that there's a problem with the COMPUTER, rather than the monitor... Please follow my tips here.

I was given a faulty f1703 by someone as it was out of warranty, had no help from HP and bought another brand replacement.

Same problem everyone else seems to be having. Press the on button, came on for a second or so and then went blank. Press button again, turn on again and the same happened.

I managed through trying time and again after pressing on to quickly press menu, then go down to Factory settings, press select, go down to Yes and press select again. This reset to the Factory settings and it seems to be working okay. Been like this now for about a week. I don't know how long it will last - if it goes again will try re-soldering. Guess I won't be buying HP products as this was a part of a very expensive system.

Make sure that everything is connected to the monitor properly. Go to the back of it and make sure the VGA or DVI cables are secured and then check the back of the computer to do the same.

My bet is that your monitor is on it's way out. If this is true, it will get worse until it gets to a point where it no longer works at all. Connecting the monitor to another computer should confirm my suspicion. The monitor has probably developed a problem with some capacitors inside. The parts are not expensive, but finding a shop to do the work at all may be a challenge. If you're handy with a soldering iron you might want to have a try at it.

The only troubleshooting step I can offer here, is unplug it, and press the power button down for about 15-20 seconds, to flush any trickle power remaining in the unit. Then plug it back in, hook it up and try turning it on again. If this solves it, great! If it doesn't though, then I would check either with HP directly or with your place of purchase to see if your issue can be covered under limited/extended warranty. If you are out of warranty though, LCD repairs tend to jump pretty high, and usually end up being more than what the monitor is worth, so it may be more economical to replace it at that stage.

Bad capacitors are a plague now, most likely cause of the black screen

simply remove the doomed and caps that have color leaking from the top. and replace with duplicate good caps from your local electronics store

we have here , like 1000s of black screens posted here now.
all the same all with CCFL lamps. that die. same solution.
older monitors have a power saver mode inside it,
push the front button called menu, then see OSD menu
then find and turn off power saver.
if the OSD fails to show up; the CCFL are dead.
this monitor was made in 2007, and 2010 is the starting year
for ending the usage of CCFL (starting on large screens working to small)

im reading your manual for you now, free.
page 4 tells you it has CCFT (T mean Tube, L means lamp)
same same.

all old HP monitors are made for old PC 2000 year.
