    What happens with led on the front? Will it turn off after starting? If yes, the problem is related to the power supply most likely. If not, then if you have another monitor, connect it and set in the display settings some high-contrast color scheme (right-click on desktop, Properties) or set black background and keep Display Properties window opened in the middle of the screen, so that'll be your highly contrast image. Connect your HP back and under bright light check if after the display blacks you still can recognize the window you left opened on the desktop. If yes, then your problem is related to the backlight (CCFL lamps or inverter). If no, then to the power supply.

    When exactly during starting does it black out? For example: After logging on, during Windows startup, during BIOS?

SOURCE: monitor blacks out

You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

SOURCE: monitor comes on when booted, then blacks out.......

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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.

Philips Brilliance 200 W 6 Flat Screen Monitor blacks out


sounds like the monitor is burning out or color is out of alignment could be result of burning out and no it's not worth repairing it. had one guy repair a montior a while back, could be looking at easy 200 to 400 bucks repair. not worth it. much cheaper to buy.

My monitor light comes on but there is no signal.


Isolate the problem. Connect the problem monitor into different computer. If the problem monitor worked on another computer, try connecting a CRT monitor to the problem computer. Once the display comes back, change the screen resolution.

Blacks have changed to blue on my PC Monitor


Can you check your monitor's device settings (on physical buttons on the monitor) and check for changes to the Hue or contrast setting(s)?
It sounds as if the hue or contrast has been adjusted slightly, just enough to be visible.

Computer monitor goes blank after initial start-up reaches the desktop


Try setting your graphics card output to something simpler like a basic 640x480 resolution 64k colours and see if it still does it... it maybe that you have the resolution/colour depth to high for the monitor to properly handle

if it is stable at the lower setting slowly increase untill you reach a point that you and your monitor are both happy

LCD Monitor blacks in and out for 1-2 seconds


does your monitor have an external transformer as the psu ?
If so, try disconnecting at mains for about 5 seconds and re-connect. failing that we'll need to dig deeper.
