what is the power consumption of a led tv
Note that some late-model flat LCDs actually have backlights that you can turn down to consume less power or produce a dimmer image. The 45 watts that a 20-inch LCD TV uses is about what it takes to charge a notebook PC, while the 55-inch plasma's 507-watt consumption is closer to that of a large refrigerator. Of course, some sets, such as Panasonic's 50-inch TH-50PHD8UK plasma, can be more efficient than others.
