Power supply for LCD TV

I have a Phillips LCD TV that takes a 12v/3.5amp DC input. The model
calls for an AC/DC converter. I would like to put the TV in my boat
and run it straight off the 12v batteries without having to use an
inverter. Is this possible, what would I have to do to make it happen.

Thanks
Mike
 
I would strongly suggest to get the proper adabtor for your set. It
will have a voltage reglator and a protection circuit including a
proper rated fuse inside.

When the alternator is running in an automobile, truck, or a boat, the
output accross the battery can be in the range of about 14.2 to 14.8
Volts. It will also surge up and down at times. This can do damage to
the TV set. In the electrical of any vehicle there may be transient
noise, and other interference that the TV cannot take.

When I was working in servicing, I used to get in a number of devices
a few times per week where the user thought they can go streight in to
the cigarette lighter of their vehicle. There were many times where
the repair was not worth the cost.

I would be using the TV when at anchor and just using my house
batteries. It's not be a big deal just to buy a small inverter, but I
was just trying to simplify things and I wasn't sure how much energy I
was using going from 12v to 110v back to 12v. It's not worth a new
TV !
Thanks for the advice
For my lcd tv I checked the schematics, and all power input

went to switching converters, and nowhere else.
These are quite tolerant for their input voltage,
so I used the battery as is.
Have not had any problems so far, and dont expect any.
