Working fine night before. When powered on this morning for the attached picture. Have tried powering off/on TV and box. All cable appear to be fine. Did this several times and no change.
If this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case by case basis please provide the full model code and the serial number of the device as well as your best contact phone number, name, and email.
