Just purchased a 2016 3010DS Sunseeker. Having trouble with cable tv. Aleady tired booster button, didn't work. All 3 TV's will not pick up cable channels. Did a factory reset on all TV's (set language, cable, etc) still not working. Called dealer who tried trouble shooting over the phone, no success. Never had this problem with travel trailer, I'm I missing something. Please help before I lose my mind.......
