I am servicing someone's Dell laptop who's screen stopped working Saturday night.
When I start the laptop the is a sequence of 8 beeps that keeps repeating until the OS is completely on.
The VGA connector works fine when connected to another monitor.
I also replaced the screen with another Dell Inspiron N5040 laptop which had the exact same connectors. (This Dell laptop is just for parts and not operational.)
This screen didn't work either? It is possible that this other screen also may not work.
Everything indicates that it is the screen.
However, could it be the cable? Is there anything else that may not be working causing this issue?
The video card must be working since the VGA connection works.
What else might it be before I tell him that he needs to buy a new screen sine both screen do not work.
