Hello,
Check in the menu if the mirror mode might be checked (mirror mode)
Try unplugging everything, HDMI cables, antenna, and power supply, wait five minutes and plug it back in.
If there's no result and if you have access to the menu, perform a "reset" or "factory reset" or "initial setup" (see menu) but you will have to redo the entire installation and settings.
