Wholehog 3 console hung after turning on

Good day.

My name is Andrei Vershinin. I am an engineer by theatrical lighting in the city of Novokuznetsk, Russia. I work with the Wholehog 3 console, some time ago to happen next trouble:
the next switch on the console screen after the BIOS it just hanging (blank black screen). Attempting to change the os to a new - no effect. Just did not lead to positive results changing bios. Can I revive a console is not sending it to you?

Best regards Vershinin A.A.
