I have just opened an HP W1907. It does not open from the back like Dell!!! The black plastic bezel with the HP logo on the front must be removed.I pried mine lose and broke most of the plastic nibs that hold it in place. From examining the bezel, it appears the a thin hook should be slipped in between it and the light gray plastic then pry up the back of the black bezel. The nibs on the black plastic bezel are facing downward and you must somehow lift them up and over the matching locks on gray piece. If you pry on the black back piece, as in Dell, you will break off four post the have screws put in from the front.

The issue if your light bulb behind the LCD matrix is burnt out you need to replace them. This is common for these monitors. The bulbs simply snap off an on by a connector to the high voltage power supply. When you open the monitor up, you will see he board with HV supply on it Trace the two (red an white) wires to the backlight (bulbs) and verify by looking at their ends looking for black discolor at he ends of the bulb (This means the interior of the bulb is carbonizing = shorting out). Most times the monitor will shut down into orange light, but sometimes it will not ignite the fluorescent bulb)(s).
hi the cause is screen back light not working properly. you need to remove the back cover of the monitor to access the internal part of the monitor. then look for the connector of the cold cathode fluorescent tube back light going to the power inverter board of the back light you will noticed a dry joints which cause a loose connection that is why you hear a sound that cause of spark. you need to re soldered the connector or replaced if totally burned.
happened once to me, (I have this exact monitor), heres what i did that fixed it:
Unplug all cables from monitor, leave it unplugged for a few mins.
Replug cables in starting with first the power then let it come up, then plug in the VGA cables, and see if that fixes it. If not use the buttons on the front to switch input channels and maybe you can get it that way.
perrycdoq, Did you do flashlight test? Is your monitor also "blank"? Did you visit this old net blog? http:///www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ Do some reading there then come back and tell me if you think same thing might be wrong with your unit. Will you do the troubleshooting or contract out the work to qualified electronics technician to fix units "switch-mode-power-supply / inverter ballast circuit? 12fixlouie
Check your monitor cable, try to reseat it (VGA / DVi port) at the back of the computer. If it still does turn off try to reseat the graphics card (if you have an expansion card) If reseating wont fix it, try this monitor to another computer and see if it still turns off. if not, then it is a problem on the video card of your computer, if yes it means your monitor is faulty.
your monitor could possibly have a backlight problem.. the wires to the lights are known to come off the lights in the screen.. if you try to check it your self be careful the lcd screen and lights are very frigile, nad can brake easly..
