TV tuner quit working

Is there any chance you have an electric amplifier that accidentally got turned off?

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?

You don't need special RV televisions. Most everyone, when they upgrade, just go to Walmart, Best Buy, or any other store selling standard TVs. We have had Samsung LCD and LED in ours for years.

Jensen TVs claim to be "RV ready". They claim a ruggedized chassis and higher temperature tolerances. Both may be true but whether it makes a difference is debatable. The average TV you can get at Best Buy, Wal-Mart, Amazon or whoever will probably serve just as well. I have not seen anything to prove otherwise. The performance of the television will be based on the same as how it performs at home.
The biggest problem I have seen with RV televisions is poor mounts and poor mounting to the RV.

It sounds more like you have an antenna problem and not the TV. What kind of roof top OTA antenna does the RV have. Do you have a switch box to select between Ant, Cable, Aux, ect.? When doing a new scan for TV channels are you sure you have selected TV or Antenna and not Cable? There is also certainly an antenna booster in the coach and if it is not on or not operational you will not pick up much of anything. This is usually a wall plate with a teeny tiny light on it. On the OTA amp is on. No light and is the correct setting if you are hooked up to campground cable. Some RV's use a separate switch or a button is located on the connection box mentioned above.
Let us know what you find.

NO! And don't buy RV toilet paper either.

As mentioned, there are NO RV model TV's and as clarified here, no RV toilet papers! I like Sam's TP but hate Costco TP. I bought and returned the Costco TP (no, only the unused part but I still got a refund for it all). I am a Charmin fan so we now pick up a huge pack of Charmin at Costco.

Thanks for all the responses. Yes we have tried all that was suggested plus tried a analog to digital converter but since I cannot get the tv to channel 3 or 4 that won't work either. It is only on a sub-channel of channel 8, will not add any channels. And since no getting to 3 or 4 cannot use for cable/sat either. Seems a shame as not that old a unit. Guess we will just get another TV at Walmart etc. and call it good. Thanks all.

I took mine to a TV repair shop when it stopped picking up channels.
They replaced the antenna connection board. Cheap fix. Got even more channels than I had before.

That and check your coax cable.
They get tired and bent etc. and digital is very sensitive.
The other TV in my RV stopped picking up channels and all I did was buy a new cable and all was fine again.

There still is such a thing?
