OK, I'm no the most electrically inclined RV owner but this one has me scratching my head. I own a 2005 Newmar class A gas coach and when I hook up to the park cable the tv always says that no signal found. I come back later (few hours) and the signal is there and the tv programs all of the channels as usual and works perfectly the rest of the trip. Any thoughts on what is going on? Thx in advance.

On ours we have to turn off the antenna booster and then tell the flatscreens to rescan for available channels. The scan process can take 4-5 minutes if you select both analog/digital .

Some televisions actually go out and find what signals are there. Sounds like your TV is doing that automatically. Normally on a digital TV you would have to go into the menu and then select TV and something like antenna or air mode. This will give you menu selection of antenna or cable. Select cable and then tell the TV to scan for channels. If you want to see if this is it then do it manually on your TV and see if that happens very quickly instead of having to wait a couple of hours.

That has happened a few times with our rig, so I automatically scan for the channels if they don't show up as soon as you turn it on. Sounds like yours does the scan itself after a short time?

Thx everyone! That sheds a bit more light on the deal. I appreciate the input for sure.

YES. when you first hook up the TV is "Programmed" from your last stop.. Some Televisions will, from time to time "Auto-Update" as it were.. (rescan for stations)

You need to

1: Aim the antenna (I find the Winegard Sensar Pro which replaces the common wall plate or which is the only device approved for installation BEFORE a box of many buttons in the antenna lead) very helpful here.

Then Scan for channels (Making sure it's set to "Antenna" or "On Air" not to cable) every time you park.

Mystery solved! It turns out that the added HD converter box that was added to receive over the air channels has to be turned off in order to auto program the cable channels. Works like a dream! I love bonding with my "new to me" coach....
