Question 12 volt TV

Can I instal a flat screen tv on my boat?
that runs off my 12 v battery?
and can I instal an antenna that will get satellite reception?
Who would do this for me? My local boatyard is not interested.
Maybe the Geek Squad?

Re: 12 volt TV

There are TVs that are 12V.

https://www.amazon.com/Free-Signal-T...NsaWNrPXRydWU=

As for reception, that’s the big problem. A dish would have to be on the dock. At sea you would have to own a large yacht with a self locating disk.

I just ran DVDs with mine at sea, if I had time. ��

It would be a DIY project, unless you know someone.

Re: 12 volt TV

better get a little invertor , then you can use a cheap mains TV

If yore marina is accomdating , they might let you mount a standard domestic sat dish near the boat ( the piles being useful ) that way you can use a standard sat installer or DIY

Re: 12 volt TV

Looked at 12v tv's and ended up with a mains tv running off a small inverter because there was a much better range of mains voltage items available. We already had the 350w inverter. Power usage is tiny with a 22" tv.

Reception is via a yogi aerial clipped to the spinnaker track. Freeview available but no chance of satellite.

Re: 12 volt TV

We bought a Dell monitor that was 120 volt plug, going to a 12 volt brick that powered TV. We just replaced that power plug with a 12 volt cig lighter plug. The entertainment system has DVD player that we connect to the monitor. We don't get TV service, but can watch our DVD. Draws very little power.

Majestic makes a complete line of 12 volt TVs.

Re: 12 volt TV

About inverters. It would probably be best to use a ‘true sine wave’ inverter. Some electronics have problems standard inverters.

Re: 12 volt TV

Yes....

Do not hire geek squad to do an install like this. Homes dont move and are not exposed to corrosive environments (mostly).

Where are you located? There are entire businesses focused on providing just what you need.

STOP YELLING!!

Look for a marine electronics installer, or look on the KVH website for dealers in the area.

Re: 12 volt TV

When I was looking the 12 volt selections were quite limited and seem to be poorly rated. 120 volt gives you many more choices.

An inverter is the way to go. Modified sine wave inverters work quite well with all of my electronics - I see no need to go full sine wave. My 35 Y.O. Heart 2000 powers my TV, DVD player, computer and power tools quite well.

Re: 12 volt TV

Many flat-panel, nominally 120 V TV monitors actually run on 19 VDC using an AC-DC converter. You can get inexpensive 12-to-19 volt DC-DC converters that will let you run off 12V ship's power, which is what we did.

If you're not comfortable with wiring for the above, a small inverter as described in the previous replies is also a good solution.

19V is possibly too much to draw straight from a 12V system, but we run a 28” monitor that has a 14.1V brick transformer (for the AC voltage it would be plugged into on land) that we’ve wired straight into our 12V system. Seems to run fine.

Re: 12 volt TV

I was able to find a small TV that ran on 12v.

Many small electronics that have a wall wart actually run on a small DC voltage, you just need to shop for 12v.

As far as antenna something like this works near shore.

or this

I'm using one of these right now,
