Could be a faulty monitor, or could be missing the driver information for the monitor. Usually when you first connect it will use a generic driver to start but then should automatically download and install the correct driver information for the monitor. Could also just be a faulty cable, power or VGA, HDMI, which ever you are using. Try using different cables first, then you can google search for the correct driver and manually install it.

The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :-

Dark blue ink splodge on my computer screen


Check the warranty - I recently got an acer lcd from a friend (purchased as package deal like a eMachine), he bought a new one, and found it was still under warranty.
Try "Auto Reset" on the monitor setup panel, on monitor - not on computer.
I forgot the proper name but one of the light emitting diodes might have gone bad which causes lines, streaks and blobs (same as on laptop screens).

Screen went black


I don't know. I've never actually replaced parts in a monitor. If the bulb is expensive, it might be best to buy a new monitor. They're cheap nowadays. Or you can check if there's warranty on the monitor and it can probably be fixed for free.
