We have just moved house and I have finished setting up and plugging in my home theatre system – we have a Marantz 5.1? Amp and 5 Wharfedale speakers (2 main, 2 surround, 1 sub).

Then I tested it and the DVD sound was only coming out of one speaker, but I found I had plugged one of the audio cabled into the wrong plug, so I fixed that

However, now the remote will not work…. I thought the batteries were flat so I changed them and still nothing.

When I press buttons on the remote the red light on the top of the remote comes on, so I know the remote is sending a signal, but the amp is not receiving it?!?!  - even when I point the remote directly at the amp it does nothing….

I have not managed to locate the manual for the amp yet, but does anyone know what the problem could be - or what else I could try??

thanks in advance!
