12 volt led TV's

Looking for input on 12 volt TV's. Trying to make things a little more simple since I am going for 2 new LCD/LED tv's, one 32" and one 28". If I go this route I don't need to run through an inverter and should be more efficient.
Comments and suggestions as to TV's. As always cost is a factor.

I bought a 20 inch LED/LCD off Amazon that works and views great. Has an adapter for 120v. I'm using a separate DVD/CD player but they make them as a single unit for less than $175.00

FWIW, most flat-screen TV's operate from 12VDC internally. The AC power cord feeds a converter which changes it to DC power.
If you have the wiring schematic for the TV it's not hard to find out if yours is that way. Any electronics repair shop should be able to install the required DC input jack.

I bought an RCA TV with a built-in DVD player that has two power cords. One is for 110V and the other is for 12V. I have a fused 12V socket that is directly connected to the house batteries. Since many LED TV's run on 12V, this is a more efficient way to run them when boondocking rather than using an inverter. I think this is a good idea.

OK been looking a couple days now. Need a 28" and a 32" TV, Jensen is 12 volt but the cost to take out a converter YIKES. Samsung has what I need but how much will it cost in terms of power to convert from 12 volt to 120A/C. I already have two smaller inverters that should work but trying to be power saver when boondocking or anytime for that matter.

Just start shopping...

Visit the store and look at the power cord.

If 120 vac pass, but if it has any kind of adaptor look closer.

Look at the adaptor and if it states "output 12VDC" then that will work.

You will need a power cord with correct connector but most are standard.

We built a 12 ATS that has female connector for factory cord and a proper connector on a new cord so it will use coach battery until shore power then it switches to adaptor.

All plug in.

Did just that today. Samsung has one at Costco 32" 12volt converter. Now All I have to do is get the old TV out first and find out if I have a good 12 volt supply in the front, I know I can do this in the rear but think a 28" will do very well there(but then again bigger is better RIGHT).

Should I run through inverter or battery direct?
Well.. that is a good question.. I have 3 answers

Though we call the house system "12 volt" it is not. It is 12.5 to around 15.5 depending on what is happening.. (The highest is equalization which can actually go higher) Some have exprssed the opinion that this higher voltage has damaged their 12 volt TVs (Most never measured the output (no-load) of their power brick supply).

I do not believe they are correct but I'm not religious about it.

So answer one is "Some folks think running off battery direct is not a good idea"

Answer 2 is addressd to them...MY SAMSUNG is a 14 volt unit.. ALL voltages likely to be encountered on the RV 12 volt system are within +/- 20% of that (in fact most will be within 10%)

Finally: My answer.. I think it is more efficient to run battery direct.
I also notice that the dangerously high (15+) voltages in fact any voltag over 13, is CHARGING and when CHARGING you do not worry about which is more efficient cause you have shore/generator power.

I just bought an Insignia 28 inch TV from best buy. It is a 12v 4amp TV that comes with a 110 to 12v power brick. I was able to use the 12v power cord that cane with the original Jensen 19 inch TV. I moved the 19 inch Jensen to the back bedroom and was able to use the power brick from the Insignia TV to connect to the 115v outlet in the bedroom. Works great

I originally tried a 32 inch that was 12v 5amps that would have worked but it was a bit too big for the TV support arm. Going from 19inch lcd to 28inch works well. New TV is lighter and much better quality.

Well I could not stand it any longer. So I went to Costco and got two Samsung 32" 8# TV's. Got the one in the back installed today , now working/thinking how to put support in that big hole left by the old TV and then a good looking cover. They are not 12volt they are 19 volt but there are 12 to 19 converters around at good prices so I will still in time run the rear TV with 12 volt so when the sand man comes along all I have to do is turn off the TV not get up and turn of the GEN. OH the over the air pic on the TV in the bed room was outstanding.
