I have an HP w1907 LCD Monitor. Yesterday the monitor just went blank. When I turn off the monitor, and turn it back on, the desk top shows up for a few seconds and then blanks out again. When I test the "sleep" button, the "monitor is going to sleep" window appears and then disappers. Therefore, commands like this are visible, but the desk top is not. When I reboot my computer (HP), the monitor will come back up for a few seconds, but it then blanks out. The sleep function is off, all connections have been checked and double checked, I've removed the monitor from power and then re-connectetd, no chages were made to the monitor settings, but the monitor still only shows up briefly and then blanks out. As stared earlier, this just started out of the blue.
Any ideas? I have the same problem, goes blank after a couple seconds, says its going to sleep, then sometimes I can get it to come back for a second by switching it off then on but it blanks right out again, and it does it on more than one computer so I know its the monitor..any suggestions for fixing it?
Same exact situation here. Monitor is HP2159m about 18 months old. Unfortunatly I'm afraid Rommel Dadula is probably right in suspecting hardware issues.Same exact situation here. Monitor is HP2159m about 18 months old.

There are controls that turn off the monitor, both in Windows control panel and the monitor itself. The system should know if activity is happening, and should not blank if active.
Look at screen savers, too.
rwhite97, If your pc is working fine with substitute monitor, and w1907 lcd unit does same (black screen, or blanknblack screen) when connected to a "known good" pc, then you should visit and read some stuff at this 2005 blog. http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ Then learn the flashlight test and what it means. Then go to YOUTUBE for video clips on lcd monitor disassembly and lcd monitor repair if you are into do-it-yourself repair. Remember this!!! Your w1907 unit uses the same basic design and operation principles that ALL brands of ccfl back-lit lcd monitors use. Good luck with the repair.

Oct 26, 2009 - so this monitor was not in warranty so i took it apart i found a wire broken off one of the backlight bulbs, ( be very carefull the bulbs all four of them and the lcd screen are very very fragile ) so i soldered the wire back on and put it back together and rechecked it it has been working like new
I also have a hp w1907 monitor which also powered on for a second and then go blank with the power light still on.. it was out of warranty so I had no loss so I took it apart..I found one of the wires broken at one of the backlight bulbs { becarefull they are fragile and there is four of them, two on the top and two on the bottom... and the lcd screen is very fragile } I soldered the wire back on and it all work fine... just remember where all the screen parts go.
If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.
sounds like you have a backlight problem, the wires are known to burn off the ends of the bulbs of the back light..if you try to repair it yourself be careful the lcd screen and bulbs are frigile.. there is 4 bulbs two on the top and two on the bottom of the screen ,, keep every thing in order when taking apart
it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.
