What does reference code s0900 mean?

If your television displays a message containing, error code s0900, please try the following troubleshooting steps:

1. Check that all connections are tight (from the wall to the Digital Set-Top Box and from the Digital Set-Top Box to the TV)

2. Power cycle all your main/secondary Digital Set-Top Boxes 

Power cycle the receiver by unplugging it for 15 seconds then plugging it back in.  If you have a clock on your digital set-top box wait until the clock displays, then turn on the power to the box.
