I have a 1500w inverter. I presume there is no way to make the thing
into 12v. What I most want to know is what type of 19" HD flat screen
uses the least power (LCD?) and what is the rating on the TV to look for
to find the lowest power one. And yes, cost is a major factor. I do have
shore power at times, but would like to be able to use it on the hook.

And for those of you who insist upon philosophy of life with your
cruising. Yes, I am a real cruiser some times. No I am not a purist. Why
should I be? Purism is usually stupid. Along with being a cruiser, I am
a sports fan, a news junkie, a conversationalist, a poker player, an
explorer, a reader of literature, and about fifty other things. Why
restrict my world?

I would no more insist upon only cruising while cruising than I would
insist upon not reading while sitting on the ****ter, so as to be a more
pure ****ter. Stupid idea.

So, HDTV flat screen recommendations anyone?

Free advice is worth what you pay for it, but here goes from a long
time, full time cruiser (ex) and EE....

Keep the 1500 W inverter for your microwave and coffepot. The standby
current will probably exceed the TV's current. Get a smaller one - we
used a 350 W which ran the 16" Panasonic TV, Magnavox DVD recorder,
Motorola Digital converter (for the DVD) and sometimes when the
Admiral would forget, a 60W lightbulb.

Look on the nameplate of the TV (sometimes it's also on the box) for
something like "0.9A" or "100W". A - Amps, W = Watts. Naturally the
lower the number the better.

A rule of thumb is that whatever Watts is listed divided by 10 = the
number of Amps drawn from the batteries. If the power is given in
Amps, multiply by 120 first. This takes into consideration the
efficiency and idle current draw of the inverter. Usually the Amps
will be less, probably because inverters are better now.

Hope this helps!

I'm not sure what you mean about making it into 12 volts.

We have a 2000 watt sine wave inverter/charger and it runs a 30 inch
HD flat screen just fine. Our house batts driving the inverter have
about 1000 amp-hours of capacity which is more than enough for an
evening of watching DVDs, running a couple of small fridge/freezers,
and several laptops.

Sorry, what I meant was that I presume there is no way to make an HDTV
run off 12v without an inverter.

If you think a 19-inch, flat screen TV has anything to do with cruising
you're delusional. But, then again, what addicted TV watcher isn't
delusional.

Watching all those many hours of brain-numbing television has sure killed
way too many of your few remaining brain cells.

Go to an electronics store and look at some 19-inch TVs you'll find many
that have a little, plug-in power brick that outputs at 12volts. Duh!

Buy one of those and further destroy your brain vegetating in front of the
tube if you don't want the inefficiency of inverting from 12volts DC to 120
volts AC and then right back to 12VDC.

Sheesh!

Standby, or idle current is the Amperage the inverter draws while not
powering anything but is turned on. Of course we all turn the inverter
off when not being used, but it pretty much is also added to whatever
it's powering.

I've seen 1500 W inverters that have a 2.5 Amp idle, and some as low
as 0.5 Amp. Another factor is the inverter is more efficient at about
half power or so.

This is not all that much of an issue for folks with larger house
banks and/or easy means to recharge.

So the questions are, what size and type boat? What Amp Hour house
batteries?

You can find a 12V TV, but they're a whole lot more $$$

Basically, size the inverter to the load.
