It sounds like you have a monitor with a common problem. After a few years some LCD monitors
will blow a power supply. The problem is caused by parts called
capacitors overheating in the confined space of the monitor. If you are
good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work
fine. The capacitors do need to be installed with the correct + and -
connections, note the stripe on the old one and insert the new one the
same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
I hope this helps, if so please rate my solution.

There is a flourescent light that backlights the screen. If your screen brightness control will not make the screen any brighter, then the backlight has stopped working. You will either have to replace that light or replace the monitor.
Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
Sounds like a dry joint or a dirty control.
In either case, its probably a case off job.. You need to consider this carefully as you are dealing with potentially voltages up to 30,000V. In all honesty, you may be better off going to your local Thrift Storel where they often have screens for under $10.
Before you take the screen apart, look on the back for a couple of holes close together with one marked FOCUS. The other MAY be marked Brightness or SCREEN.
with a longish NON METALIC screwdriver, turn the recessed control gently in the SCREEN hole slightly one way, then the other and then back to its original position. This may remove any dirt/dust accumilation.
I CANNOT STRESS enough, the need for EXTREAM care here due to the VERY HIGH Voltages involved.
Usual disclaimers apply..
Best take it to a shop or replace it..
The monitor thinks the "AUTO" button is depressed continuously. If water or something got into the button membrane and shorted it out it could cause this to happen. You would have to open up the screen to try and clean the buttons but that's not a guaranty.
Odd. The manual doesn't mention anything about that.
It almost sounds like one or more control buttons is partially shorted or leaky.
That can happen if a foreign substance got in it or it was stored in an unheated garage or shed for a long time, etc.
My HP f1703 is almost 3 years old and started having this same problem. My fix got the display to stay on. Don't know how long this fix will work. I set the monitor brightness to 51 and contrast to 41. You may have to adjust to your levels to your appropriate enviroment. Levels may determine how long the monitor stay operational. Do NOT set your monitor brightness to factory levels it will just start to recreate the problem again.
The monitor should be on with the blue button lighted. If the screen is acting up (you turn it on and the display lights up and then it turns off within 2 to 5 seconds)
Try decreasing the brightness level down as much as possible. Wait 15 to 30 seconds and see if the display comes back to life. If not, turn the monitor off and on again and try the procedure again, if necessary.
I believe the monitor brightness level, set at 100 by the factory setting, is over driving the display and causing the protection circuit to cut off the flouresent lamps that light the display.
HP had an issue with this display, and had a notice to replace them if the problem occurred during the warranty period. They extended the warranty period from Jun 04 to Feb 06. Check with HP Technical Support to determine if your monitor is cover.
