No power to screen, everything else is fine.

I have a Dell Inspiron 3520. While on it, pc shut off. Turned it back on, everything running, only no screen, no logo, no power to screen, no beeps, nothing. Fan is running; power, battery, and cpu lights on.
I tried removing cmos for an hour with no power or battery in it. Same issue. Tried holding power button for 60 seconds...same issue.
Did the screen blow out? Or the video card? Or the motherboard?

Someone, please help me with this headache. I run a home business with this computer and I am in a lot of panic.

Thanks,
