My receiver doesn't work either and I've tried asking (in the wrong threads, I admit that), but no one seems to know what's up. I have no top menu like you and I am unable to select any frequencies. I can scroll the "background" with the bars, but the selected frequency never changes. Unless I pull out my headphones.

But even when I pull out the headphones and select 91.1 (a working frequency where I live) and put the headphones back in, I hear absolutely nothing, not even static. It's like the tuner isn't even active.
