The TV we had in our camper for 4 years will not pick up any channels. There is one left in memory so that comes in with great picture. But tuner is apparently bad. Is this due to vibration damage? Should we replace with more expensive "RV" model that is made to withstand travel and temperature extremes?
The fact you are getting at least one channel says the tuner is working to some extent. Have you done a rescan to see if it will reacquire the channels? Is the source setting set for cable or air depending on your current connection? If the scan is not acquiring new channels, is the antenna amp on? Is there a factory reset to see if you can start over?
