Can you give us some background on what happened. The more details the better!

Sounds like a failed GPU. First think id do is test it on a separate monitor using the display port. If it shows a picture, then I’d start troubleshooting the display connectors and cable. Did it display any odd behavior before it shut down?

Throwing spaghetti at the wall to see what sticks is not very effective! Following a good diagnostic process is a lot better.

One good clue is the fans running at hight speed tells us there is an internal issue. SMC which controls the fan believes the system is overheating. So we need to get a better idea what happened to diagnose what area within the system needs to be looked at.
