Samsung galaxy note 10 screen not showing when I power up but hear sound. What to do? Tried holding power button and didn't work.

If the screen isn't coming on it is either damaged, or has gotten disconnected.

If the tablet is under warranty still, I would then suggest you contact the manufacturer about a repair/replacement.

If, however, it isn't under warranty anymore, then you have the option of doing the screen replacement yourself (if you feel comfortable doing it) or taking it to a local tech/repair shop to have it done.
