I searched some old tv threads and found one with similar problem. We have been on the road for over a month now and have stayed at over a dozen rv parks. Twice we have not been able to scan cable tv channels. Both times the parks maintenance have came with a small tv and the cable at our site was working. Today we bought a new Roku tv to see if it was our other tv. No luck still could not scan any cable channels. We tried hooking the cable direct to the tv and still no channels. Our tv has worked at other sites but not these two (includes the one we are currently at). Any recommendations? We can pick up air on both tvs. Booster is off when scanning channels.
