AV2 ignoring remote control?

Hi all,

I've come in tonight and tried to control the AV2 with the remote, but it's refusing to respond?

I've pressed "AV" on the remote and then all the usual buttons ("Input", "AV Volume" etc) and it's not responding.

The remote is working with the DVD player so seems to indicate that the remote is working fine.

Is there a way to hard reset the AV2? Or do we think there's a fault?

Also when I last used the AV2 I had it in "Midnight" mode. Is there a way to turn this off using the front panel buttons?

Thanks in advance,

Andy
