Television
 
We needed a new TV for our 19 - the old one did not work so well after bouncing from the bed to floor while driving. We NOW store it in a bin under the bed.

I wanted a 12V TV but did not like the selection of off-brands available. After poking around it looked like the Samsung UN22F5000 22" TV might work on 12V.

Bought one: Amazon.com: Samsung UN22F5000 22-Inch 1080p 60Hz Slim LED HDTV (2013 Model): Electronics
And a Radio Shack 12V cord: Enercell Heavy-Duty 12V/5A Power Cord (8-Ft.) : Power Cords | RadioShack.com
with "T" tip adapter: Enercell Adaptaplug T : Adaptaplugs | RadioShack.com
NOTE: One tip (of your choice) is included in the price of the 12V cord.

Be SURE to plug the tip in for "+". And it works - at least so far.

How did you know it was 12volt?
 
Thanks much -- I might do this instead of getting a Jensen TV. But I am curious, how did you know that it worked on 12 volts before you bought it? Do all (or most) LED tvs work on 12 volts? do they have an external power supply?

Televisions
 
There are also RCA flat panel LED televisions which if used in the home use a step-down transformer to reduce and rectify 110v AC to 12v DC. There are 15"and 19" in this configuration. I bought the 19" and use the 12V plug in with the correct plug on the end for the TV and it works just fine. I had a 19" with DVD in my previous RV for a couple of years and it also was fine, no issues. The bonus was only I paid $105 CN for it from Superstore.

The "brick" is actually 14 volts. I was not positive it would work, only reasonably sure. If it had not worked I would have used it on the inverter. You need to do quite a bit of research. That is why I posted that THIS TV appears to work.

1) Read all the literature and reviews (often good info in them) on Amazon.
2) Read all you can find on the manufacturer's site.
3) Google and sift through lots of extraneous hits for useful info.

Thanks Doug.
We have the same TV and a 12v power option may come in handy. The part numbers & links are appreciated.

Actually - one of the most useful tools in determining if the TV will run on 12V is seeing it at a (REAL - brick and mortar) store. You can verify the existence of an external "brick", look for the voltage, and look at the connector. And try to buy a 12V (cigarette lighter) cord for it.

Note: A TV which wants a well-regulated 12V supply may not be happy with an RV's 12V. When charging it be over 14V, and even with nothing much going on it will be 12.5V or more. Everything I have seen/read indicates under voltage is safer than over voltage.

Here's what I bought and it works fine...

At Radio Shack they have at least 20 tips for their 12V cord - and a set of tips to help figure out which one fits your device.

I fried a AM/FM/Short wave radio by using a Radio Shack 12V cord and the wrong tip. Make sure you keep all instructions that come with the cord and with the device you are powering.

Using Samsung TV on 12 volt.

I am using the above Samsung TV that comes with a 14 volt brick that coverts 120 volt to 14 volts. I am using the TV directly on the trailer 12 volt system without the brick. I got into issues with " ground loops" causing interference on video and sound due to connections between the Samsung and the Jensen 12 volt stereo that Escape furnishes.

Before I was done, I had to install isolators on sound going from DVD sereo to TV, sound going from TV to DVD stereo, and composite video going from DVD stereo to TV. The units I used as were:

Amazon.com: Scosche Eso34 Ground Loop Isolator: Car Electronics
and
Amazon.com: C2G / Cables to Go 41145 Composite Video Isolation Transformer (Black): Electronics

I also had to use male to male adapters to get everything connected. If I had it to do over I would have been better off going with a regular 12 volt TV from Jensen or other. The cost after all was done was a wash. The advantage being the Samsung has a better picture, is lighter, and I have no inverter losses involved. I put the little isolators in the overhead cabinet to get them out of sight.

Hope this may help someone out.:rolleyes:
