LCD CURRENT DRAIN on INVERTER

Not with it, sorry. LCD TVs of course

If you look in the instruction book under "Specifications" or on the data plate fixed to the TV there should be the power rating. It will be expressed in "Watts". An inverter to supply that should be a little larger, say 20% and should be of "Pure Sinewave" type.

Many 54cm TV go as low as 40W at 240, however some will be around 50W and possibly up to 60W depending on screen brightness and efficiency.
A DVD will be around 13W at 240v
Together the total may be up to 70W and as Allan said there is a loss in the 12v to 240 V AC conversion. This will take the load on the 12V battery to close to 100w at 12v, so at least 8 amps draw of current being used by the inverter to create the 240 supply you need.

Does your battery pack have the ability to supply 8 amps very hour you use it?
One nights viewing may be 1/3 to 1/2 of the charge capacity of a fully charged 100ah battery.

I have a 19 inch 12 volt TV.
It’s a Phoenix and is advertised as a ultra-low current draw because it has LED edge lighting.
The 19 inch (48 cm) is rated at 30 watt and 22 inch (56 cm) draws 40 watt.
If you intend connecting the TV off a Vast satellite decoder don’t buy a 240 volt model run off an inverter as the losses add up to about 20 watt. Buy the decoder with a 12volt inbuilt power board and it will draw 8 watt.

Hi kevmac,
I run a 19" 12v TV and DVD player all in one. I have a 250w inverter that plugs into cig socket to run the Vast decoder box. I can run the tv all night for 5 nights before needing a recharge, using 2x 80 deep cycle batteries.
All TV's that are LCD LED are 12v and some come with a DVD player in them so you won't need an inverter.

Our house LCD tv is 240v (80cm) to the tv and has no supply box but uses 80 watts when working .
The Caravan tv (15") has a transformer that converts 240v ac to 12v dc and also has a direct dc lead that plugs into the 12v van supply and uses 3amps when on tv mode and 4 amps when running on DVD mode. These figures are from an amp meter.

We find that the tv using dc current directly from the house batterys a better function.

Consider this.

Kogan are offering a small flat screen Tv WITH and inbuilt DVD player and PVR for $139.

That is less than the cost of a decent small inverter...and it runs direct off 12 volts.

day after day, the good reasons to run an inverter get less and less.
