No channels found

Solution

I suspect your antenna is simply not providing a strong enough signal for the tuner to lock on to when it is scanning for available channels then. I have used several OTA antennas for home and camper use and had the best results with powered (amplified) units.
How far are you from transmitting sources? When you scanned for channels on your TV, were any errors indicated?

Does your antenna require an external power supply? If so, is it connected and working?
