Wii is soft brick

If you have a soft brick then you can fix the unit. If the cause of the brick is from a failed mod attempt then you're obviously not under warranty so you can discount any responses that advise you to "Send it in to Nintendo."
Instead of doing that I would visit the link below and follow their methodology to determine if you can Un-brick your wii!
