Took the new to me 2009 Greyhawk to frontier town this week and hooked up the cable coax for the first time. Not the first time camping with her. Have already logged a week of boondocking with no need for cable until now. I Turned on the entrainment center TV, switched through all inputs - no signal. Antenna TV and Xbox working fine. Try the other TVs, again no signal. I take one out of the mounts and hook it directly to the coax feed outside, using a different cable to rule out a bad one and still no signal. Call in maintenance and they arrive in under ten minutes, excellent response time by the way. After an hour of fiddling and testing etc. the technician and myself remain baffled. His little test TV works fine. After he left I spent more time reading through the manuals inexorably searching for a clue. Mind you, his test tv worked fine inside the rig. I take a break then have an other go at it. I find a channel search menu under an obscure setup setting some three layers deep inside this Sharp tv's menu options. I click inside and yet another layer of options then low and behold, it asks to scan cable and digital channels. It's default is AIR. Who uses air anymore? I select cable and run the scan. A progress line appears then like a miracle; from the deepest Depths of this programming nightmare, this horrific setup jungle yields channel after channel of good quality to nice and crisp cable tv. I had to repeat this process on the other two TV's. You'd think the manuals would state one must run a channel scan in order to get this tv to work. Nothing. Just thought I'd share that. Otherwise having a great trip.
