Hello,
Try unplugging everything, HDMI cables, antenna, and power supply, wait five minutes and plug them back in.
If that doesn't work 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.
