Re: 12v tv recommendations

I would suggest rv is fine but don't know if anything in that size range is designed to run off a 12v power brick. A DVD player, like anything else, is likely to be 110-240v if it is dual voltage, and not *12*-240v. I think you'll have better luck with just biting the bullet on an inverter and looking for products with the features and reputation you want.

I have a jensen 32'' It was the largest 12volt model I could find. It has a great picture.

Re: 12v tv recommendations

I recently found an LG 12v blueray player at Target for $79. Threw away the brick and wired it direct - works great.

Re: 12v tv recommendations

I started doing some research on this and Jensen seems to have the best 12 volt TV's. They are made for holding up in harsh environments like you might find on a boat.

Re: 12v tv recommendations

Just went thru this search. Several brands (e.g. - LG) have models that come with either an internal or external brick that converts from 110VAC to 12VDC. If you find one of those, then simply cut the brick and out wire direct. Unfortunately, I was unable to find one of the new low energy usage models with that setup. After figuring the energy usage options, I went with a low energy model that draws 110VAC and just use the inverter.

Good luck with the search!

Re: 12v tv recommendations

second that on the inverter.

if you check the back of the tv (or it may be marked on the box) you can see how many watts it draws. you'll just need an inverter a bit larger to run the tv.

since 120v tv's cost about half as much as 12v tv's it's a no brainer for me. you can also buy a tv with a built in dvd player in the 120v models but i've not seen one in 12v. i had a cheap dvd player at home and just use that.

tv antennas also come in powered versions - but none in 12v that i know of...

Re: 12V TV Recommendations

The marine antennas all run on 12 volt Go to best buy and check their tvs for the volt brick There are several but all small 22'' or less

Re: 12V TV Recommendations

The problem with cutting the brick, is one needs to check to see if it converts to 12vDC. And check to see which lead is neg/pos polarity.

Re: 12V TV Recommendations

I bought a Majestic flatscreen w/DVD 12volt from defender, it claims to be ultra low power, something like 20watts. It has a bunch of ins and outs, USB's, I don't use any yet but it seems like it could do whatever I need in the future. 19"x11" not huge, but I never had a massive TV shoreside so this ok. The only thing it wont do is fill the role of a cheap TV, defender gets a chunk for it. I buy almost everything from defender, and if they have something I don't look much more. When I'm home in VT for summer, if I order before 4pm I get it next day.

Re: 12V TV Recommendations

Although it is much smaller than what you are looking for and not blue ray, we have a NAXA 12vdc/100-240vac TV/DVD and are happy with it and the price. Small, yes, but it is less than 10 ft across the cabin.

There are larger sizes as well.

My big worry(I found one of the brick style 24" monitors) is that it is 11-13v tolerant, and I suspect it might see more variation.
EDIT: Agree re negative and positive, I'm going to mark both sides, cut then check the voltage coming from the brick.

Re: 12V TV Recommendations

"it is 11-13v tolerant, and I suspect it might see more variation."
You're right to worry, since alternator power is nominally 14.4 volts and that would exceed the "12" volts from a brick. Low voltage shouldn't be an issue, since 11.6 volts is nominally a totally dead battery on boat and 12.0 is likely as low as you'd ever want to get while partying with the tv.
Of course if you do something like use a relay to lock out the tv's power circuit while the engine is running...that ought to keep it away from the alternator power too.
