Problem with my Onkyo receiver

[guitarplyrstevo]

I just got my brand new Onkyo TX-SR574S from my job today for $10! Anyways, im trying to go through the setup menu and im trying to change my mains to small instead of large. I clicked setup and im trying to click "(2. SP Config)" but it wont let me. The only things i can click in the setup menu is "1.Component" , "5.Audio Adjust", and "6.SAT RadioMode". Everything else has parenthesis around it and i cannot enter it. How would i resolve this problem?

Unplug the receiver for a few seconds and then plug it back in. That should reset the microprocessor. If that doesn't help, then try resetting to factory defaults: turn on the receiver, press and hold Video 1, and then press the Standy/on button (on the receiver itself - not the remote).
