If you used to have a good signal then suddenly became cutting-off and can't be fix by relocating the antenna, rebooting might fix the problem. You can't fix it by turning "Off" the power on the remote and turn back "On" again. However, disconnecting the power supply then plug it back also fix the problem as well. If rebooting doesn't fix the problem try relocating the indoor antenna close to a window.
