My sister's laptop is booting up, but the screen is staying blank

[malrashid65]

She owns an MSI Apache Pro GE72, and I'm trying to fix it for her. She said she saw a BSOD flash right before the problem began. The issue was that when she booted it up, nothing would come up and it would shut down immediately and boot up again after a while. After fiddling with it for a while, I've gotten to the point where it stays on, but the screen is still black. It doesn't even show the splash screen/BIOS.

A list of things I've tried:

• 
  -Disconnecting power & battery
  -Removing and switching RAM sticks (This is where it started to stay on longer)
  -Holding power button for 30 seconds while battery & power disconnected (it stayed on permanently after this)
  -Disconnecting the CMOS battery for 1 minute

Any help would be greatly appreciated, thanks in advance

Have you tried connecting it to a monitor or tv? If you aren't even seeing the BIOS screen then it could be the display itself.
