How to disassemble w2007 monitor - HP W2007 LCD Monitor

Some monitors change colour if there is damage, internally, within the signal cable. Try another cable if you have one.
Alternatively, it might be that the monitor is near an extremely strong magnetic source, such as big loudspeakers?

If both monitors give no signal, the computer has a video graphics card issue or a motherboard problem, now when you checked the video cord, do you change it? if you have a extra cord, sub it to be sure.

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.

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?

Yes, the likely cause is the power supply/inverter board, in most cases it is bad capacitors and solder connections. If any capacitors are puffed or show a slight dome shape at the top, chances are it is open.

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.

Those speakers require a certain cable connected to the computer aside from the monitor's own cable.

What operating system are you using?
