You may have dying power supply due to bad caps as shown here:

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Driver will not cause the screen to go black, look for bad caps inside, it is very common problem.

I am facing problem with my Samsung LCD monitor, when I switched on my Computer it shows the bootup screen, after booting the LCD screen goes blank, when i turned off the monitor and again turned ON the...


Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

My princeton VL2018W will flash the screen when first powered on but goes blank after. With repeated unpluging, the display used to stay, but no luck


floresa57, After lcd panel "flashes" is the lcd panel "black" or is it both "black" and "blank" when you perform the flashlight test that every LCD owner should know how to do and interpret the results? Do you have warranty? If no, then read more responses in my FIXYA profile for clues on what YOU will or what YOU won't do to fix your BLACK SCREEN monitor!!! Floresa57, the basic principles of design and operation of your Princeton VL2018W are same as all other brands of Fluorescent backlit LCD monitors!!! It can be fixed. READ, READ, before you do anything. Understand the reason WHY your monitor is now black and lifeless. Follow all the LINKS to other web sites so you will be informed and less likely to be overcharged on a repair job that should have cost less than $50. Good luck Floresa57. Rate this on FIXYA if it was of some use to you. 12fixlouie

Hp flat panel monitor comes on shows logon and then blank screen


Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.
