The amount of power a TV uses varies by the size and type of television. Plasma televisions use the highest consistent amount of power per square inch while microdisplays use the lowest. A 46-inch plasma has about 906 square inches of viewing space, which takes about .30 to .39 watts per square inch. Amps is equivalent to watts divided by volts, so 0.35(906)/120=2.6425 amps. A plasma TV uses 2.6425 amps.Know More
A microdisplay rear projector television uses the least amount of power at 0.11 to 0.15 watts per square inch converting to 0.13(906)/120=0.9815 amps for a 46-inch microdisplay, or less than half of the amps used to run the plasma television. LEDs are purported to be even more efficient, at as little as one-fourth the power of a plasma television.
LCD televisions vary widely, using 0.16 to 0.41 watts per square inch, so a 46-inch LCD television could use as little as 1.208 amps or as much as 3.1 amps. Potentially more efficient, a traditional cathode-ray tube television uses 0.25 to 0.40 watts per square inch, which is a rate of 1.8875 to 3.02 amps for a 46-inch television.
The most energy-efficient television with the least current is the microdisplay. Plasmas and LCDs run double to triple the energy consumption and current running through them.Learn more about Television & Video

TV picture problems can usually be spotted by checking to see if there are any issues or abnormalities with the TV's On-Screen Display, or OSD, which can be checked by using the TV's remote, not the cable or satellite remote, and clicking on the volume, channel and input buttons to see if the TV's projection lamp is working properly. If it isn't, those patterns that are usually displayed on the screen will look distorted or disappear entirely.Full Answer >
