How many watts does a TV use when not on?

Answer 1

The standby power rating is one that manufacturers tend not to publish. However, the few that I have measured (yes, I am enough of a nerd to actually do it!) have been in the region of 5W - 15W. It seems that the power varies depending on how much of the television is turned off and how much is active. All of them need to have enough running to sense an infra-red signal from the hand control but at 15W, I suspect that significantly more of the control circuitry is left alive as well. Looking at all the televisions that spend most of their time on standby, the total power used must amount to a huge figure. Perhaps it's time to start a campaign for lower standby power from the manufacturers, or even turn off the mains supply to the TV when we are done with it - although that does mean having to walk to the TV to turn it on again.
