Is a LCD 12 volt TV run direct from the battery going to use much less power than an ordinary TV though an inventor.
I am guessing YES!

yes more economical because the inverter is not 100% efficient. so using unnecessary power.
Or to put it another way the inverse ratio of the spondulicator is proportional to the square root of the pelgum bracket multiplied by reflective and reactive component of defractulator, unless the square of the capacitive inductance to modified thomb pin is greater than the inbuilt losses known as the GT factor.

yes more economical because the inverter is not 100% efficient (anywhere between 70 and 95% actually). Therefore using up to 30% unnecessary power.

A large number of domestic products reduce the 240V A/C to 12V DC, so one with a 12V input just removes the reducing stage, however LCD screens are prone to problems unless the supply is regulated, maplin supply a suitable regulated DC/DC power supply.If your tele also runs off 12v, it's probably got it's own inverter Road Runner.
I doubt if the difference is worth bothering with in terms of electricity used.
From my point of view, ferkling about with one gadget instead of two makes more sense.
If you are charging torch or toy batteries, 12v is the better option electrically and ferkling aboutly.
No need I went to college.have u been googling wildman
Sorry John cannot believe that you forgot to factor the internal losses of the battery.:thumb::thumb::thumb:agreed Roger.....but the new breed of 12v tv's have a clakvalve in series with the capacitive inducer.....if its connected by the anode AND cathode to a 0v supply it cancels the GT effect and with the moded thromb pin works much more efficiently so a 12v 110ah battery will last, on average, 12 years without recharge.
Your TV is designed to work from its power supply ie.12v. The voltage from your battery will be about 12.8v this slight over voltage will not cause it to suddenly go bang but will over time degrade the LCDs (picture) until eventually it will be un-watchable. The problem is made worse if you are charging the battery at the same time i.e. running the engine or using solar panels as the voltage will be even higher oh:Why over a period of time???????

Not quite sure what you think a diode does, in fact it prevents current passing in one direction, it will also drop voltage across it the amount depending on the type of diode.Just remembered that i fitted a diode well over a year ago to the 12v lead supplying power to my Pace sky box.
The info can be found Product Information
i have used this cheap mod on my sky box with no problems
will also do the 12v lead to my New Tv

I imagine that TVs sold for the leisure business are more likely to have regulators than those sold in supermarkets etc, which are mainly intended for household use.
Wilman is quite correct diodes are not voltage regulators, if you wish to protect sensitive equipment whilst using battery as a supply.
This is what you will need click here
