Take a peak- and note what the name of the port your device is connected to is. If you are using a Coax cable between your TV and the U-verse receiver you may just need to change the channel up or down to restore your picture. These steps will work not only for cable boxes but for other devices as well.

Each port on the back of the TV will have a lable. Change the TV to the new HDMI input to see if the issue is resolved. All you need to do is to find out what is wrong and try to fix. To check it remove the cable box and insert the other external device.
