To many people’s disbelief, faulty memory can prevent laptop LCD screens from turning on at all. I’ve witnessed this on Dell, HP and Averatec computers and unless they are unique (they aren’t), it can happen to any manufactured laptop. What you won’t see happen to the LCD is distortion or a fun array of 70′s colors flashing around the screen. If memory is the problem the LCD won’t flicker on at all. It will stay in its off state after the power button for the computer is turned on. If you’re seeing weird things on the screen you’ll have to diagnose a different route cause but if it won’t even flicker, memory is a good place to start (after checking the AC adapter and battery for sufficient power, of course).
On a different note I have not personally witnessed the same type of thing happening to desktop computers and their external monitors.
