What did I do wrong?????


From the sound of it (with the snowy screen), you're not getting any kind of signal or output from your converter. We need as much detail as you can describe.
Your tv needs to be on channel 3 or 4 depending on what the box has it set to. I think that's the problem here. I think right out of the box they come set on channel 3.

As for reception issues, post your TV fool plot and we can check it out for you.
