Okay, I understand that devices that can be turned on with a remote use power to detect when they’re being turned on by the remote. My question is how much do they use while they are off? The same as they use when they are on?
Check the spec sheet on the back of the manual, or the manufacturer’s web site. I just checked a couple of SONY and Toshiba TVs, and the stand-by power varies from 0.07 to 1 watt. Some older TVs use considerably more, but still much less than when it’s on.
The EnergyStar compliance specification says 1 watt or less when a device is in stand-by. So if it has an EnergyStar label than it will be less than 1 watt.
Oops, I meant 3 watts. Here is more info.
It depends on the TV.
Some older ones have a pre heat circuit. This was a circuit to keep the tube warm so you didn’t have to wait for the tube to warm up.

scr4, wow, Im happy that you mentioned the manual, because there are so many tvs that they
can’t all possible be the same. I don’t think mine uses any at all when its off since it doesn’t have the quick on feature.
handy, does it have a remote that can turn it on? If so, there has to be a circuit in there watching to see if there’s an “on” signal coming from the remote. That’s what the OP is asking.
