Onkyo TX-RZ720 in need of repair

[DJ MC]

Hey there

Something in my Onkyo TX-RZ720 blew during a lightning storm last night. It turns on and you can scroll through all the different menu options, but the volume is immovably set to MAX and there is no sound.

Is anyone able to assist me with a repair or suggestions?

Thanking you in advance
