There is no reason to use the home button during a "Hard Reset". Try the following and see if it works...
NOTE: Doing this will clear 'all' the data on your tablet, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.
Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.

Thank you so much for hopeful solution. The phone is blinking onto power then off again, a faint navy screen then black) . It doesn’t actually start or go to any menus. O you think it is a battery problem or more serious! I know that hard to know from a written description!
It is hard to tell. But, to be honest, it sounds more like something you won't be able to fix on your own. If the device is under warranty, I would contact the manufacturer. If it isn't, then try a local tech.
