Hi jcgha...,
After checking the speaker connections, try doing a Web Upgrade - Settings menu, to reload the software.
If this doesn't work you can try reprogramming the SD Card, see our Techy Stuff page -
link - New SD Card, or replace it. If you need an SD Card please email us on - thebrennanb2 @ gmail .com - no spaces, with an address for delivery.
