Can you see a dim image when you view the screen at a sharp angle?
If so you have a backlight problem, the fault could be a faulty inverter that supplies high voltage to the CCFL lamp or the CCFL lamp could be faulty.

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

Display lights up then quickly goes dark


It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. If you do see the ?Start? button then either your backlight tube is bad or more often the inverter board is bad. Let us know if you have any other questions and please don?t forget to rate this posting.
