Bmckell, Yes! You too will need to goto YOUTUBE and view (FYI) some video clips of LCD monitor disassembly and or LCD repair and learn why your "CCFL tubes" light up for only 1-2 seconds! You are dealing with a problem of NO WHITE LIGHT!!! Have you seen the NEW style Curlie-Q screw-in CFL Light bulbs? What if they made the Fluorescent tubes "straight, a little thinner, and a bit longer, and hung them on the reverse side of LCD panels with a mirrored surface of some sort to help reflect the WHITE LIGHT forward and thru the LCD panel!! Wouldn't that be quite novel. If only we could make the ELECTRONIC BALLAST CIRCUIT reliable enough to last 6-7years. EBC's in light bulbs are to be called Converters (ac to ac), and CCFL's EBC' are to be called Inverters (dc 12v to ac). I hope that this info will set you on your way to lighting up your monitor's CCFL's again. Remember this. The inverter gets dc from the main "switch-mode-power-supply" (SMPS) if the smps has not gone into SHUTDOWN mode because of a FAULT detection. Now that I have said enough to get both of us in trouble, please rate this response on fixya if this info was of any help. Bye for now. louie12fix on fixya or lmistyrel @

This problem can occur due to several reasons. And there are many steps that need to be taken care of. Try this step shut down the computer completely and then look for the F8 key on the keyboard once you locate the key hit the power button and then keep on tapping the F8 key until you see the start up options before booting into windows now try the options safe mode or safe mode with networking.


Now try these steps and see if this works out. and if this solutions help and let you log in computer then go ahead and restore your computer to an earlier time.

Hi, i have an HP Pavilion dv2000 & it had recent motherboard problems, so I had it repaired in the HP Service Center. They replaced the motherboard & so far, everything was okay until yesterday....

Yes, the GPU is faulty. either replace the systemboard or reflow the GPU. Second option is cheaper and you can do it yourself. There's a link for a diy guide to fix that issue.

does your screen look like this?

LCD monitor goes blank

It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

HP dv2510eb Display Problem

Video problem. Could be an easy fix, could be something loose like the cable. But you would need a professional to look at it.
