TV for caravan -LCD v CRT

Hi billv or is it billy. Why not get a 12v LCD TV that they put in vans. No need for inverters just connect into your 12v supply.
Just a thought.

I've got a 10.4inch LCD monitor/TV that runs direct off 12volts (or 240V via a plugpack). Works fine as a TV.
Says 12V at 3.5amps on the back. But I measure 1.2amps at 13.8V when its turned on.
Its a cheapy off Ebay from Hong Kong that I was going to use for mapping but it didn't quite fit where I wanted it.

I have a DSE 18" computer monitor/TV that runs off 12v no issues. Will work through a cigarette socket but would be better with heavier wiring from either the battery or junction box.

i have a 15" telefunken 12v dc/240v plugpack LCD TV in our van and it works a treat,2A @ 13.8 volts.cheers Paul

We're thinking of getting a notebook and an external (USB) TV card. I'm pretty uninformed on these things though, and not all that IT literate Any of you Gurus out there got any knowledge on this ?

Thanks for the replies. Perhaps I should rephrase my query. Will a 34cm LCD TV use less power than a 34cm CRT TV when powered via an inverter? If so, by how much.

We bought a 34cm Polaroid LCD TV for home, when I opened it up I found that it had a 12vDC power supply so I had to try it out on the C/T battery. Worked a treat and drew about 2.4 amps.

If you were to run a CRT TV through an invertor I am sure that wold draw more than 2.4A. I believe that up to a third of the power is used to operate the invertor.

I wish I could start again with my query. We already have a CRT in the van (240v) and it's very good. But we wish to have TV when we are away from 240v which is often when we travel during winter. So the size of the inverter is important. I'm told that I'll need a much bigger inverter to operate (start up) a CRT than a LCD.
Once they are operating I don't think their amperage draw would be much different, but the start up draw on a CRT is (I'm informed) much greater than the start up draw on a LCD.

All Inverters loose some current as a percentage of their total output, however the better quality Inverters loose under 10%, like anything you can buy cheap elcrappo products - but you get relevant elcrappo results.

This loss does NOT effect the running of the 240v product it is running.

The 'loss' is only counted as a loss in the battery consumption numbers, so it's only minuscule when compared to the consumption of the product, eg TV

That's why a "quality" Aux battery system is used to counter ALL the power consumption (loss's) from ALL accessories, including the fridge, lights & inverter etc.

Example:
OUTPUT POWER: 200W continuous - 600W surge
OUTPUT VOLTAGE: 240VAC +/- 2% ( PURE SINE WAVE )
EFFICIENCY : 96 %
Price: $264 delivered
These Inverters provides clean, silent 240V AC power for your mains appliances from 12 volt battery power and provides a PURE sine-wave output, which is the cleanest power available for those applications that require the very cleanest & purest in power. They are microprocessor controlled and have full electronic fault protection. They also have LED indicators to indicate Power and Fault conditions. The unit also features a very low standby current to save power.

Many thanks to all, particularly Robin Miller. I now know that if we change our CRT for an LCD the power draw will be about two thirds less which determines, in part, the size of the inverter we'll purchase. Again, many thanks. And it's billV not billy.
