Power Consomption of LCD Backlight

Is it true that when on Full beam, the backlight on a LCD HD TV, uses alot ot power, thus producing very big electricity bills?

As you will or will not know, I have a Toshiba 32C3030DB Regza C-Model. When I turn my Back light lover, the picture becomes dark. turn up the brightne4ss, and the picture is somewhat whitewashed.

I am still in a state of confusuion about automatic backlight control.

Please Help.

Hello Andrew.

You're correct. If the backlight is at its maximum brightness, then it will use a lot of power and the picture will appear washed out, and blacks will look grey.

Set it to the minimum, and power consumption will drop, and the picture will get a lot darker. This is a good setting for viewing movies at night, but not so good for watching Neighbours at lunchtime.

What the automatic control does, is look at the light in the room, and adjust the backlight to make it appropriate for the conditions. It's actually a pretty good way of doing things, and can work very well.

So in other words, the Active Backlight control is like a room light sensor, that measuresthe light in the room, in my case my bedroom. However on one of the shelves by my bed, is a desk lamp.

On the very top shelf of the shelving unit, I have a ball shaped lamp shade with a bulb inside on a Chrome silver 3 legged ring stand , which shines not as light as the desk lamp. When I watch a film, or something recorded on Sky +,
I turn the desk lamp off, and use the light ball, Would you recomend that or get a lamp with a proper shade on it?

I have no idea what you mean

The TV should be able to cope with most sorts of ambient light.
