Model hp1702 power supply ok
monitor old very very old. 13 years old in fact.
this is a CCFL back lamp old monitor
so is the back lamp dead, that it.

front panel menu button OSD data now? this is first to do.
OSD is always first then check the backlamps for DEAD.

that is not some simple monitor no,
it has its own processor inside, and that needs power too.
it must convert VGA video RGB top LCD data., all non trivial.

Power Indicator: Green - Power On mode.
Amber - Power Saving mode.
Blank - Power Off Mode
so if it turns its self off
that means the Brain inside sees gross errors.
or the brain side lost power.
there are many tests.
in a pro show we check all power busses, if the black lamps work
the connect up i2c to the I2c port and scan it for errors
this is what we must do to see if the BRAIN inside sees gross errors.
there is no other ways. to do that.
or if connected the CCFL tubes the monitor turns off
well the CCFL tubes are shorted. and if are, then the brain
was correct to shut it off or risk a fire.
see? it really is very smart.
My colors its no good
If your computer's graphics card is working ok and the monitor does the same thing connected to another computer and the lead from the computer to the monitor is tight, there are no damaged pins in the connector, the most likely problem is that your monitor is failing and it may be cheaper to consider getting a new one.
Absence of red and blue colours, which, with the green give you your picture, indicate a failing component in the monitor.
My monitor hp 1702 is
It sounds like you have the problem with the PC itself, you can try this monitor with another PC just to narrow down the problem.
The PC mayhave hardware problem usch as bad power supply that may explain why you cannot even open the CD tray.
I have three of these HP 1702's that all flicker
You should replace them as a set as I show in the pictures (all the one by the heat sink and the one by small blue caps, 6 total), those that did have domed top were checked bad because they have high ESR (Equivalent Series Resistance). If you use standard caps from Radio Shack they may not last since they are not low ESR type. I use PANASONIC FM or FC series from Digikey. You also need to check those 4 transistors by the small blue caps since when the DC filter caps went bad it can take out the transistors also.

I hope he monitor does have bad lamp assemblies also.
Dim display
The
dark screen with faint, hard to see display is due to the failure of
CCFL
(Cold Cathode Florecent Lamp), which is the back light or the Inverter
board, which provides high voltage to the CCFL. So, it is recommended
that you get it properly checked by any professional for replacement of
CCFL.
Also, refer here to my earlier solution to a similar problem, which was rated as very helpful
GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!
CreativeTECHplacement of
CCFL.
