(Toshiba Satellite) Opened Rear Cover, LCD Screen Black

[bisons]

Hello! I'll try to make this concise.

I have a Toshiba Satellite C75D-B7100. I wanted to change the RAM, so I opened the back cover. Nothing appeared out of place when I closed the cover back, but something isn't right. The laptop powers on bit the screen remains black. I have been unable to locate the hardware issue.

Can anyone help with this? Thanks everyone.

Did you swap ram and what happens when you put the original ram back in?

Hi
Did you remove the battery before changing the RAM module(s) ?

do you have a spare screen to connect to vga out.
If display appears on external screen,
there is a key sequence to have screen display go internal / external & both screens

Press Fn key and F5 several times
F5 should have square symbols indicating screen [ ][ ].

If laptop really not starting up
remove power lead & main battery
press on button for about 15 seconds
re inset battery and try again

@C12Friedman, I did not swap the RAM out, I opened the laptop but had a last hesitation. I closed it after opening.

@mbarnes86, I indeed removed the battery! (I'm fearful of shock, haha.) I don't have a spare screen handy but that's a great idea. I'll see if the laptop projects there.

Thanks for your responses!
