Laptop display is black, finals soon, any help is appreciated

[Mari_1]

Things I've tried:
-Draining power completely
-Holding zero
-Reseating RAM
-Waiting overnight without power
-Shift+F8+Power
-Using restoration drive (the screen is just black. It won't allow me to do anything.)

If it helps, I had recently installed avd pc tuneup, and the amd auto detect software from the website, I'm worried I was careless and downloaded the wrong thing, messing up my display somehow?
Last night, my laptop wouldn't let me extract some zip files, so I restarted and it gave me a blue screen. It restarted again, now giving me a black screen. It hasn't changed or done anything differently since. The fans will run, and the charging led is on. The bottom gets hot.

I have a Toshiba Satellite C55Dt-B5128.
I don't have a monitor to test display on.
I'm willing to have everything deleted although I will lose pictures, art and a looooot of game data, but at this point I'm that desperate..

Please help. I've scrounged every part of the internet and nothing has worked. I have a final for class on July 7th and I'm very stressed about this. I can't just buy a new one or have it repaired. I researched heavily although I'm no tech master, I am desperate. My only functioning laptop is the one I am using, which hinges are falling apart and no keys work. 🙁

Have you tried getting into Safe Mode and doing system restore?

My screen is just completely black. It will not show anything, not even the start up logo.

What about any white writing before (or after) the black screen?

I.e., options to enter BIOS?

take a flashlight and shine it at the screen very close up. there may be very faint images indicating that the backlight has gone bad.
also, if your screen has a latch, sometimes the latch port has a switch that turns the backlight on and off.
if no latch, open and close the lid several times while its on(the lid switch could be acting up).

No, as soon as I start it up, it's completely black. I let it there for an hour, and still nothing.

Tried this and there is no image? It seems like just the display is just off? But I'm not sure

Hi, a simple test, try to go into the BIOS if you can't then you have a faulty component on the motherboard.

test the laptop on a friend's monitor for testing purposes to see if displays on it or not.
