12 volt TV

virtually all small LCD flat panel TVvs are
12 volts. The power cube you see in the power line is a 12v - 110v converter. Just eliminating that can give you what you are looking for at a reasonable price, however, all of them are highly susceptible to voltage spikes.

As Don said
Most of the flat screen, LCD tv's are 12 volt units, and the little box is just a converter. You can hook it up direct to the battery, but I would prefer running through an inverter. Seems like kind of a round about way to do things, from 12 volt to 110 volt and then back to 12, but a voltage spike could very easily trash your TV. The little inverters large enough to run the TV are pretty inexpensive, particularly when campared the the price of the TV.

Surge protector or voltage conditioner
I have one of those small lcd tv's on my boat and was considering wiring it into the 12 volt system rather than shore power. Does anyone know if there's such a thing as a 12 volt surge protector or voltage conditioner that one could use to keep the voltage more even. if so where and how much? Thanks for the help

Just got a digital converter box from Radio .Shack
with a $40 coupon from Uncle Sam. We have a 15" LCD TV which is few years old and does not have a digital tuner. I figured it be better than spending close to $300 for a new one. As the boxes available and which are in the coupon program are 120V I will run it out of the inverter together with the TV. A test showed excellent reception with our omnidirectional antena plus you get more channels as the bandwith allows each TV station to put out 2 or 3 additional signals with varied programing. My out of pocket cost was like $21. Walmart has one for $49 but I think the RS is a little better offering enhanced digital sound circuitry. I'm ready for 2009 when the analog signal disapears.

The usual issue with DC voltage is overvoltage
which rarely occurs. If you can get the specs on the TV and it's good for from 11 to 16 v DC then you need do nothing else. When you're on shorepower, your charger should start out at 14.2 to 14.4 V depending on your charger settings. When at anchor, it'll almost always be below 12.8v.

I did it
This past christmas I did exactly what your asking about. Ran me $89.00 fom Best Buy. THey were getting rid of them. I will probably suck it up and pop for the converter in the fall. I only got it for the radar images on the weather stations

BobM, on DTV
A UHF tv antenna is all that is needed for the DTV to analog converters to receive the digital signals. I am using one now (about 3 years) at home with my ordinary roof top TV antenna (it has the little V laying on it's side shaped thingie for channels above 13). Most local stations are sending 2 channels ( for example here in Seattle the NBC station KING5 has normal programming on channel 5.1(HD), and weather on 5.2 (SD), their digital channel number is 48), but some are sending more. The local PBS station has 4 channels, 9.1, 9.2, 9.3, and 9.5, with HD programming. The biggest issue with using an antenna is the signals are quite directional, so aiming my antenna is critical (so I have a rotor). The converter boxes that are being offered for use with older TV's are Standard Definition only, and will not do High Definition. FYI, I am currently using a Over the Air High Definition Receiver to receive the digital signals of the local stations. When you connect this receiver to an older TV set (not HDTV ready) the picture is in "letter box" format when it is a HD program, or 'clipped on the sides' depending on the format selected.

Hey Timm R 25 Oday
I have a broadband card for my laptop. I go to weather.com and get the current radar for the place that I am located. It is almost as good as having my own radar for inshore use. I have watched a few storms come at me and I was well prepaired because of this.
