If you are getting nothing on the attached display, and when you hook up an external monitor you still see nothing, then it is probably the graphics card/GPU that is the problem and going to need replacing. Sadly on most devices today that will mean the motherboard will need to be replaced.

If your device is under warranty, contact the manufacturer and have them do the repair/replacement.
