My aunt's laptop doesn't show anything on the screen. I tried disconnecting the battery and holding the power button for a minute, taking the RAM out for a few minutes and tried clearing the CMOS again, hooked it up to an external display with a VGA cord and pushed the external display button on my keyboard, etc. I tried shining a light on the monitor to see if the backlight just wasn't working, but there is no picture at all. I can hear the hard disk and the fans start up, but the display doesn't work at all.
What could be the problem? Is there anything else that I can try?
