Router hAP RB951Ui-2nD- error

Please, I have a mikrotik hAP RB951Ui-2nD router and after the firmware update, the router did not start, only the PWR and USR lights are on, the ports do not light or flash at all, and I cannot log in to the router, even if I press the reset button, the router is simply dead. Could it please be fixed in some way or reinstall the firmware, or is it already dead. Thank you Radovan
