Try rebooting the box by removing power, then plugging back in. If it's still messed up, odds are the HDMI cable you are using is not 4K certified. The 1100 is having handshake issues with the TV probably  because the input you are using on the TV is set to 4K. If so, set it to 1080 as the 1100 box is not capable of sending 4k out, the TV may be looking for it. There should be a setting in the TV input menu to disable enhanced HDMI on that input, or try another input on the tv.
