My friend gave me his monitor, because he was having problems with it. He told me that it would work for a while and then just go blank. The green light stays on but the screen goes blank. If you turn it off and turn it back on it works, but only for a few seconds. If you wait 1 minuate and turn it back on it will stay on for around 10 mins and do the same. I was just wondering if anyone had a solution to this problem, because I have always wanted an LCD, but they cost to much and this one is free and I was hoping maybe I could fix it up and use it for myself because an LCD is much easier to carry around and the colors are so much better. Please help me out if you can.

Thsi model has known problem with bad solder joints due to contamination, you need to remove the old solder on the four inductor leads, clean the leads eal well and resolder, see my pictures here: http://s807.photobucket.com/albums/yy352/budm/HP%20F1703/
Al so look to see any one of the capacitors have bulging top, they should be completely flat top.
have you tried testing the screen on other pc if it wotks or the same effect? if you tried it on other pc and the result is the same, the screen or monitor is faulty,and needs repair or replacement, but if it works on other pc's, your pc have the problems. it could be the memory module, video card, or the motherboard or processor. also, try checking the settings, maybe you have set it to auto-off after 30 mins or so.
Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.
I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.
Well, my friend. The issue is, the dual monitor hast THREE modes: 1. Internal monitor only 2. External monitor only, and 3. Both monitor simultaneusly. You may need to keep pressing the FN combination until you reach the mode you want. (You need to wait about 3 seconds before the mode can be observed)
Have you checked your energy saving settings? Try to set the monitor to "always on" and verfy if the problem still persists.
Also check if your monitor drivers have their own energysaving options, although i doubt it.
The green power light indicates that the monitor is receiving from the
computer correctly. I suspect it is going into high voltage
shutdown. There is a safety circuit that monitors the high
voltage and shuts the monitor down if it sees anything amiss. So
the monitor comes on and then shuts off. High voltage problems
are generally not worth trying to repair. Another example of a
worthless safety feature. High voltage failures are not
dangerous, and adding the safety circuit just kills the unit when it
may have some life left or worse, sometimes it is the shutdown circuit
itself which fails!
Hope this helps.
usually this problem is caused by a faulty inverter circuit. transistors might been running too hot or a leaky capacitors also.not an easy task but try looking down for any defects on high voltage sections.
