Smart Tank 720, everything is blinking, brick.

When I "on" the printer, everything able to blink is blinking (all the buttons,all the icons on the digital screen) exept the wifi button.

I can do nothing. removing the power for 10 minuts do nothing. nothing inside the scanner. Nothing inside the printer.
