Can you please remove the battery from the Blackberry, wait 5 minutes, then put the battery back in. Test if it comes on, if it doesnt, please let me know

ok, the Blackberry has developed an internal fault sorry
It will be the mainboard in the device

This is covered by warranty so I advise you to have it repaired under this.
