First, check for a label, decal, sticker, or even embossed into the TV housing. Usually, the power requirements are on the device. Also, usually, the label will show either Amps used, OR Watts.
If the label only gives Watts, to calculate Amps, DIVIDE the indicated Watts on the label by the indicated VOLTAGE, which will results in Amps.

∙ 11y agoElectricity has several units of measure, depending upon what you are trying to quantify. In the US, the voltage of the TV would be around 120V. The amperage would likely be around 2A or a little more. The power would be equal to the voltage times the amperage.
The answer varies widely, depending on how old your TV is, what size it is, and the kind of TV it is.
First, bigger roughly equates to more power used if the TVs are the same type
Second, the types are:
CRT- the old heavy boxes that are almost gone. They use the most power
Plasma- Flat screens, but heavier and thicker for a given screen size. These still use more power than LCD
LCD- Thinner and lighter and the most efficient power users in mass production today.
OLED- Not in mass markets yet, but promise to be very energy efficient.
Bottom line: Look for LCD TVs for now, and look online for specs as to power consumption.
One last issue: The cable or Satellite box that many of us use today often uses more energy than the TV that they serve. Even when 'off' they are very much on. To get an idea, just use your hand to feel the heat on top of the box when it has been off for a while. DVRs are the worst, since they have to be available to record at a moments notice
