Macbook pro 15" late 2013 black screen

Hello, I have a problem with macbook pro 15 ", the fans are running and I also get sound, but otherwise I get nothing on the screen. Someone sometimes knows why this is please ?

It's likely the solder on the u9300. Or the backlight circuit. Can you make out any image on the screen? Usually you can make out the apple logo if your screen is clean.

If you've tried the usual nvram and pram reset to no avail then it's time to take it to a reputable 3rd party repairer. Don't bother with Apple or their authorised repairers, they will add nothing of value.

I do not see anything on the screen no apple logo sound and the running no more, this has been before with other laptops

Take it to a 3rd party repairer. Unless you are a skilled solderer, this is going to be beyond your ability to diagnose and repair. An experienced tech will be able to diagnose the problem in minutes. An experienced tech does not include Apple or their authorised repairers.
