Greetings, I just had Shaw service hooked up in my home, and now the cable box is screwing up. I turn on the box and get nothing but a black screen. No video or audio - but the guide works totally fine. I've reset the box via the power switch in the back, and after waiting for the process to complete, I get the exact same issue - no image, no audio, but a working guide.
The box was brand new 4 days ago, and hasn't been so much as touched by another human hand before today. Any help would be appreciated.
