Television's not working

Sounds like you will need to take it in under warranty for repair. I would ask them to tell you what failed to help you figure out if the problem is electrical or through the antenna port.

It looks like you aren't the only person having this problem.


LG turns off.

Are you POSITIVE you have the TV in consumer operation mode and NOT in Store Demo mode? THAT is a symptom of in Demo mode. Doug

Not that this your situation but I had a brand new LED flat screen TV in my house that was shutting off sporadically. The TV was I'm front of a window that faced the west. It turned out it was overheating from direct sunlight hitting the rear of the set. I put a piece of cardboard behind the TV to block sun and hasn't turned off since.
Could it be that your TV is getting hot? Just a thought.

Hi All.

We have had a 26 inch LG LED TV in our Motorhomes upper front area for the past 3 years. Not so much as one problem. As with everything, I have done al of my own work on every RV we have ever owned in the past 46+ years.

We have never "Broken Down", and we have never had a "Flat Tire" or a "Blow-Out", in all of these years. Of coarse I am a "Proventive Maintance Freak".

The biggest problems with any RV, a Travel Trailer, 5th Wheel Trailers" or a Motorized ones. Most problems are usually Electrial issues. I know I'm a nut case. But I do believe if you take good care of your "RV", your "RV" will take good care of you.

Think of all the "Shaking" and "Rattling" and "Bouncing". These RV's tank in just one year. If everyone really checked their RV's, I mean really check every thinig, you would be surprised at how many wires
you just might find lose.

Good Luck. Happy Travels. Dan & Jill & Two Small "Yorkies Kids" who love to travel as much as we do.

I have a 40" LED Philips in a outside bay that likes to start turning it self on/off/on/off on hot days. More than likely it's an overheating power supply and it's out of warranty so I added a 120V computer fan to the hottest area. Works fine now, but at some point it may stop working completely.
OP, try blowing air on the back of the TV and see if this helps.

Thanks everyone I'll share this information with my repairmen
.

You need to run a power cord from the TV to a ground based electrical outlet and verify the issue remains. If not then you have an issue in the coach electrical circuit. Yes, I have seen it.

One time we bought a new Samsung LCD. It would come on by itself at random times and go off at random times.
Mentioned it to my next door neighbor, who had a new Samsung, although not the same model, and he was having the same problem.

We experimented and our remotes were causing the problem. I was surprised because it had to go through two stick house walls but that turned out to be the problem.

I have that problem with one device here.. It kept operating the box (in this case it is the remote for a digital converter) causing a channel change mid-show.. I finally boxed it in a container that prevents it from operating the device... The container also protects it against accidental button pushes.. So far it's worked great (It is a cylinderical container so no way can a button be pushed).
