\015\012Power is on, but nobody is home….
\015\012
\015\012This is a common problem I see a lot and there can be multiple problems here. First off, if you have lost the backlight on the LCD, you might not be able to see what is on the screen….LCD makers are making the panels very dark and if the light has failed it is very difficult to see what may be on the screen. Try shining a flashlight on the screen near the bottom and see if you can make out anything on it.
\015\012If not, attach the laptop to another monitor using the video output, you may have to toggle through the video outputs on the laptop by using the Fn key + one of the “F” keys….sometimes it is F4. If you see your desktop on the external monitor than your screen may have died but your video card is still good. In this case, change out the screen and inverter.
\015\012If you still can’t manage to see a display, then the other issues are a virus or malware that has changed the resolution to one the video card cannot process, in which case, the hard drive would have to be removed, attached to another computer and scanned to remove the bugs.
\015\012The video processor or video card has failed on the motherboard. If the computer has not been cleaned and has run hot, the processor can suffer significant damage that can result in this condition.
\015\012Work on simple first, until you get to complicated. In the end, worst case scenario is the main board has to be replaced.
