Monitor displays fine but flases on and off every couple of seconds
When I boot up my computer, I can see the images on the screen. It does display all of the images as the computer progresses, but it keeps going off and coming back on. The monitor has no physical damage and the image is excellent.
It flashes off and on in about 2 second intervals.

Hook up to external monitor .. Does the pre boot screen pop up (black and white writing at start ) ? If display runs on external monitor then your screen needs replacing usually or if you see a vague image on laptop screen then inverter or backlight is gone .. if no display on external and no pre boot screen probably the graphics chip on laptop has malfunctioned.
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.
1. You can check the display on external monitor>If the display is blank on external monitor also, its pretty clear that there is an issue with system board
2. If the Exernal monitor comes up fine, it will be an issue with the display of the laptop, you can cross check the issue by booting the computer to BIOS, IF you get same response on BIOS as well. Its an issue with the Display itself you can replace the display panel.
Hi , The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.
Your Monitor has a heat sink issue. A capacitor in the monitor is at fault and when it heats it tells the monitor to turn off the display to save the display from damage....Problem Cost to repair will supercede the cost to replace it...Wal-mart 15" monitor 119bucks --17" monitor 129...same at staples office supply (Poof) problem solved.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
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)
