One thing you can try is Wiping the Partition Cashe on the phone

Wiping the Partition Cashe clears out a lot of old or corrupted information that can cause issues

Follow the steps below. You must follow every step and you should be done in about a minute

Turn off your phone.

Connect your phone with a USB cable
to PC or another Samsung mobile

You will see the charging icon on your screen.
Wait till it shows charging with battery percentage.

Next, press and hold the Volume up and Side key simultaneously.
You can press the volume up button just before the Side key.
The Samsung Logo followed by
Samsung Galaxy appears on the
screen.

At this point, release the keys
Phone will boot into Android Recovery mode

In Android recovery mode, using Volume keys, choose "Wipe Cache
Partition" .
Use the power button to accept that.
You will then see its cleared.

Then the top option, reboot phone.
Press the power button to reboot the phone and then sign in normally

@jamesfuller if the clearance of the cache Partition does not work as explained by @Glenntech  👍  then consider a factory reset but back up first if you can. 

If this continues then either contact Samsung via your Samsung Members App and or arrange to visit a Samsung Experience Store or Samsung Service Centre. 

If I can be of any further help then please don't hesitate. Take care.  😎

I have exactly the same problem. Phone is making sounds, the front screen works but the main screen is just black.
Have you had any luck in resolving this?
