I installed a 32 inch flat panel LCD and a dvd player, haven't found the best spot to mount the dvd player as of yet, but i've been busy doing other things. I run it off of a small inverter, will run off one battery for at least 6 hours, prolly longer, but i haven't had it running longer as of yet. My inverter has a low battery alarm if it does kill the secondary. We don't watch much TV, but we do like to watch movies and I have a dvd burner so I've been making some "boat copies" so I don't end up ruining my originals.

I have a 24 inch Dell monitor. It is mounted at my nav station on a Ergotron swinging arm. I can position it so I see it when I am at the nav station. It is also large enough that I can read LARGE sysmbols from the helm station. When we want to watch a movie we position it so we can watch it from the settee. Great! Low power, excellant resolution. So far, it has not given us any problem.

Only issue is securing it when we are underway. Currently, we use velcro ties and secure the articulated arm. One of these days I'll think of a better solution. We attached it to a HTPC that I installed in my electricala panel. That's a BIT of overkill, but it works great! Used a DC-DC power supply. But, it still uses more energy than I like. Probably the Radeon 9800 Pro card I have installed. Way overkill, but I can play games on it when I am bored.

Since we are in the marina for the summer it would probably be better if I got one of the cards that let me tie into the TV/cable system. I don't miss TV that much, so it is not high on the priority list.

I was looking at those Ergotron mounting arms. Dont know which one you have, but the one I was interested in was for mounting large display to wall.
I thought I saw some places where I could get the thing into the position I wanted ( extended or stowed) and drill a small hole straight through the moving pivot ball so that I could insert a small pin to lock it all in place.

Theres always bungy..

A good power boat friend installed the tracking dish and the large plasma TV. He really likes it but it sucks amp hours like there is no end in sight.

Our new boat has a 15 in wide screen LCD and it runs from an inverter. The CD player has a DVD oprtion with a video out connection so the CD player is also a DVD player and is 12 volts. There is a cable comnnection for when you have cable on shore and an antenna connection for on the hook. That is a pretty low cost approach that does not use a lot of power. We tend to watch TV when confined below due to bad weather. Mostly we prefer the sunset show from the cockpit.

A laptop witha 12 volt adapter is a good second choice. The new 15 inch screens play a DVD pretty well.

I was looking at http://www.flagshipvideo.com/flatscreen.html and noticed that ALL of the displays listed ("Tatung") operate on 12 vdc.

Please dont tell me you are generating dc to charge batteries, inverting it to AC to plug in your LCD's power supply, which is converting it back to 12 vdc to power the monitor......no....dont tell me that....

If i recall correctly LCD's run off of DC, however the inverter is built into the monitor. So yea, if like me you are running off of an inverter, you are inverting dc to ac, then ac to dc. My LCD draws very little amperage even at 32 inches.

I think I would be tempted to go find the output of that internal converter and install a radio-shack connector so I could run it right off boats DC...

You might be tempted but as yet there isn't a product to do this out of the box. You can get several devices that you can use a DC / DC converter such as laptop computers but not yet for LCD TV's other than the types used in automobiles and they cost a lot more for a lot less.

Radio Shack isn't a leader in this pusuit. They actually never have been. I did get some NiMH batteries there today that I could not get at Wal Mart.

I also do the lossy multiple current conversions. Why? It's simple to install and more economical, as you can use cheap off the shelf stuff for your entertainment electronics - which will eventually rot out anyway over time.

I disagree. There are in fact products out of the box, and Radio Shack does have them. They are called "connectors". I am thinking there is a good chance that an internal ac/dc converter would be a separate module inside the LCD case. It will be bulky and run hot as compared to the other electronics, so the design engineers would likely isolate it. What I was trying to say earlier is that I believe I have the skills to follow the ac power lead to the converter, use my VOM to confirm what its output is, and if its 12 volts, then I could probably install a simple connector somewhere that lets me bring 12 volts into the box from outside, and leave the ac connector to the LCD unplugged.

These things were designed for homes that dont commonly have dc available. Boats have it all over the place. I dont see the sense in wasting it by inefficiently converting it to ac for a short run, then converting back to dc when it gets where it needs to be. Thats all.

I agree it is a waste. It almost doubles the total power consumed. Making AC from DC only to do it again in reverse. You really do lose almost half to heat.

I did it with my computer but it gets more hours of use. The TV gets used not even everyday when aboard and then only a short bit. The most use is at the dock. I think the prices might come down soon. The panels are already coming down and old fashion "tube" displays should be gone in a few more years.

The off the shelf 12 volt TV sets seem to be way over priced due to lack of volume. I have a 12 volt 9 inch color tube set with VCR and it's about $400 to replace that with a similar tube set.

The plasma large screen sets flat out draw too much power made worse with an inverter. My friend says his draws more than his fridge. They use a normal household fridge aboard, but it is a 48 ft power boat with a serious engine and generator.

We used to hoist up an antenna and found reception so unreliable and programming so limited we watch DVDs now. And that last's but a couple of hours and is not a major power consideration.. at least it doesn't seem to be.

It's all hardly worth doing a fixed mount set up.. until programmming and reception issues can be sorted out. Sat TV may be a good option, but that gear is min about $750 (FollowMeTv) without the dish and the controller and the service... so this means you really are going to be watching tv.

OK geniuses.. how many AH are wasted when converting AC to DC for watching a 2 hr DVD on an LCD display?
