Galaxy S3 note 10.1 2014 won't start

I have a Galaxy S3 Note 10.1 that will not turn on or startup. It crashed yesterday while I was using it & wouldn't start back up.

I tried pushing & holding the Home & up volume & pressing the power on button with no joy.
Also pushing & holding the power on button then pressing Home & up volume buttons with no joy.
Also pushing & holding the power on button then placing a finger on the screen, as well as the reverse with no joy.
I opened the back & disconnected the battery for a while & plugged it back in without any joy.
While the back was opened, I had a battery from another S3 note, plugged that in but no solution.
I charged both batteries overnight.

Has anyone else experienced this problem? Any other suggestions??
