Hi9 plus not boot

New Tablet is red button version 128 GB flash, 10.8 inch, July 2008 patch. Power was about 42% so I plugged in charger and tablet went blank. No back light on screen.

I have held power down long tome 60 sec, no change. Try normal boot, no response. Volume up boot, no response. Battery voltage is 3.85V on both.

Have emailed aftersale 3 times 5 days no response.

Really like tablet except awful patch policy. Want to fix, please advise.
