Not normally no. Depends largely on what you have done to cause the brick in the first place i.e. State of System Menu.
A full brick typically means you have no System Menu to boot. A black screen at power on and no Preloader.
You can test by using the savemiifrii technique to see if you can enter recovery mode. Put a Gamecube controller in Port 4, press Up, down, left, right when you power on the Wii. If it works you'll get your System Menu revision in the bottom right corner. Check youtube for savemiifrii.
