TV - 12V or 110v with Converter?

So I've read many past threads and can't seem to find a consensus on this subject. My 12v 32" Insignia TV has pooped out (barely a year and a half of service) and I need to shop for a replacement.

If I go the converter route, I'll have a lot more purchase options but would sure like to find something with a higher "vibration" capability as you know the horrible roads out there we travel across the country. (I assume my TV's short life is directly related to all of these bumps and rattles.)

And if I start using a converter, tying it to my existing 12v power cord will perform correctly?

Thanks!

I believe you are actually referring to what is called an "inverter", which will be confusing to those reading this, as many RV's have a built-in "converter". This thread link below explains the differences on the often confused terminology.


Converter or Inverter (they are different)


Are you attempting to use a stand-alone inverter, typically of the kind you would use in a vehicle to plug a 120 volt AC television into?

Television -- 12v?

We do a good amount of boondocking, so purchased a 15 inch "cheap" (relatively) 12V "trucker" TV 10 years ago & it has performed flawlessly. We did try a larger (24" I believe) with an inverter but it seemed to pull a LOT more battery juice. For some of the newer TVs that really don't require a lot of amperage, a small inverter may just do the job and do it efficiently...but, should you need a larger inverter (and, can't "imbed" it somewhere out of sight/sound) the cooling fan can be a bit distracting. Jensen makes a pretty positively reviewed TV that some manufacturers are installing in RVs & that operate well on 12V (24"?) -- maybe worth exploring.

Just google "12v tv" and a lot show up. Advantage to it is that it would be drop in replacement - no extra work (wiring) involved.

Check with Skyworth TV's. They are 12 volt and built for mobile/trucking. Furrion is also supposed to be made for mobile but the one that came in our MH was 120volt. Jensen has many sizes that are 12 volt.

Thanks for the input...seems the community is equally split on going 12v TV (especially if already wired for it) versus regular TV using an inverter.

You don't need a special TV or inverter, the Samsung's I put in my TT are 12VDC with a 110VAC power supply so I can run them off either. Just regular off the shelf TV's.

As mentioned, many tvs are 12v power supplied by a wall brick that plugs into 120v AC so they easily can run off 12v with a 12v power cord. (probably home-made)

I would find a tv you like and if it isn't 12v (by some means) then, an inexpensive INverter to power it would be my choice.

I'd rather have the tv I want (for all power occasions) than to be limited by whether it is 12v or not.

We have a 120 volt tv in the MH but we rarely are without at least electric hook up.
I installed a 120 watt Samlex pure sine wave inverter for anytime we are off grid. The only time we used it so far was last year at Yellowstone National Park.
The inverter will power the 32" Samsung tv and a Direct TV receiver. I can plug it in at the tv antenna booster 12 volt outlet as it is fused for 15 amps. If we where off grid more, I would have bought a 12 volt tv. Also inverters are not 100% efficient. Most are in the 80 to 90% so you are wasting energy any time it is working.
Something else to consider is having to turn the inverter off any time you are not on shore power. I think inverters are always drawing power whenever they are connected to 12 volt.

I am told that Jensen no longer makes Electronics ???

Love the 3 12VDC TV's we have now, but too new to have any history. Will post again when the first fails, I'm sure.

I would prefer a 12v TV. The rule of thumb is that each time you switch between AC to DC or DC to AC, that you lose 50% of the power. TVs are built to run on 12v. Some of the old ones would actually use the 110v for the plasma or CCLF tubes. Now with LEDs, they all are 12v DC. Home TVs have the circuits to switch from the 110v wall power to the low power DC. In a trailer going from DC to AC and then in the TV back from AC to DC is a lot of waste. If you are only using the trailer on the weekends or only when plugged into AC, there is no issue. If you are boonbocking and using the batteries, then the 12v TV makes a lot more sense.

Some of the smaller units use a wall wart to power them. They are actually 12 volts.
