power consumption

Taking a guess I'd say because the TVs transformer is buzzing and producing heat. I suspect parts of the circuitry are live and doing the same.

Apart from the Energy waste (and argued greenhouse effect ) , TV's are one of the biggest fire hazards in a home (all that dust etc). Kill it when not in use, before it kills you.

I think you can get gadgets that monitor mains power (from the lead ) and can isolate devices on standby.

The answer is Yes..

There is power being consumed, however, the quantity depends on the age and brand of TV. The older CRC Models actually kept the High voltage charged because it took so long to warm up. These consumed almost as much power as when the TV was on. Some TV's had an indicator that only indicated that power was available. These consumed considerably less, but took longer to turn on. The newer CRT TV's consume less due to the improved efficiency of Micro-chips over Discrete components.

Some of the latest LCD TVs only have a trace amount of power being used since they are only use enough for the detection cct.

Lately consumers have become more aware of this, so many products will advertise the "Standby Power" in the products specifications.

It all depends on the make, model, and year your TV was manufactured.

Just a bit of trivia - the first "instant on" TV was built by the FBI for J. Edgar Hoover. He complained about having to wait for the TV to warm up. They modified his set to keep the tube filaments always powered.

If it was down to J Edgar , the red 'light' probably conceals a mini-cam.

How could you suggest E. Hoover would have a RED in his office he was very anti reds.

The Reds are in our rooms ! Thats why they weren't under the bed.

That was also done to extend vacuum tube life (although I doubt J. Ed was concerned about that). The original vacuum tube computers were never shut down for the same reason. Tube failures occurred when powering up or down and that was a major problem due to the large number of tubes (tyranny of large numbers) so, instead of powering down over a weekend, for example, computers would spend the weekend rationalizing an irrational number like pi.

They would also apply power to the tubes at overvoltage and undervoltage every so often to shake out the weak ones.

The latest European regulation allow for up to 3 watts max power consumption while in stand by; the people who dictate to us mainly those women who know nothing of electronics want to remove the stand by option altogether. they want all equipment to be on in use or off no in between.

NO, unless you can feel static on the front of the screen after you turn off the TV, the main High voltage flyback transformer has been turned off. The flyback transformer ramps the voltage from the power coming into it from the wall outlet up to around 10kV to shoot the electrons toward the screen to make the picture appear. This is the dangerous part of the TV, that charges the CRT, the flyback core is also the humm you hear when the TV is on.

The red led is just an indicator showing that the TV is plugged into a good source of power in the wall. It does not mean that the high voltage circuitry is still powered up. Otherwise, what would be the point of having a power on/off button?(rhetorical question)

Comments so far are pretty accurate, except for EHT being 10kv! In most ctv,s the EHT is 25kv to 32 kv(x-rays are produced over 27.5kv)- the larger the screen size in crt ctv,s, the more EHT needed to produce the illumination( they supposedly get around the x-ray emission by using lead glass)- but as I always say, always turn the thing off at the power point,& further, pull the plug from the socket- a surge down the power line, if high enough, will jump any on/off switch, & wreck your idiot box!.

The old black and white TV's were about 10KV, Color requiers at least 25KV

the power is still on even if youi turn off the tv set by romote controller, our tv set is usaslly less than 1.5W. in order that the tv set can be started fast next time.

this power include supply to led, transformer leak and preheating etc.

most of set cancel the last function.

so if you want to save energy, turn off power with its powerkey.

you must be scottish if your worried about the power consumption of a remote switch

The TV is off

the transponder is in standby

power consumption is negligible

I would be more worried about your glade plug ins - fire hazard and huge user of power

The red LED use electricity to light up. The circuit waiting for remote control command need electricity to operate. They both use DC, so there is a converter working all the time converting AC to DC.

Of course power is being used until you unplug it.

See Topic in this respect. A lot had been discussed on this subject:
