    Hello, I'm mainly concerned about whether turning off the TV, set-top box and the like is safe for the equipment itself and translates into savings due to turning off the LEDs that usually light up on standby tv or set-top box

    1.As it is economical and safe then ok

    2.But if it is not, because I think it is nonsense when it comes to savings and adversely affect the equipment itself

    If the 2nd answer is correct then please give a concrete description of why how it affects the equipment and savings I have to prove it to one person who every leaves the house for longer or shorter turns everything off the grid.

    In my opinion, it makes sense, but it is not at all about saving electricity. If you take a device off the mains, its power supply is not working, and this means that the components are not energized. Most components are not greatly affected, but the capacitors of switched-mode power supplies have simply after a while they can "dry out" and their ESR increases which causes heating and eventually failure. If we add to this that most manufacturers use CapXons and other inventions, then after a year or two of continuous connection to the power supply, such a device can refuse to cooperate.

    There is also a safety aspect, during damage to the installation, for example, "burning the zero" causes damage to the equipment, which can even lead to a fire.

    I recently measured at my place. Everything on standby draws about 40-50W. The subwoofer alone, the TV, the amplifier, the DVD player and the desktop recorder (which is also a DVD) drew about 25 watts. Plus the rest of the appliances in the house. A total of 40-50W. What consumes the most I connected to the devices that are on the remote control.... One click and everything turned off.

    The diode consumes a few tens of mW, you would have to wait a few years to come out of it 1kWh, but the equipment in standby consumes much more than the diode itself, although they are still not some large powers - check the manual.

    How it affects reliability, it is difficult to say what will prevail, both continuous operation and on/off cycles put a strain on components.

    But if there is an overvoltage in the network, such as from lightning (a few times a year is to be expected), then unplugged equipment has a better chance of surviving.

    Modern devices are becoming more and more shoddy, if such a device damages itself when no one is home, what guarantees do you have that, for example, will not catch fire?

    On TVP they recently reported that devices in STAND BY state consume about 10% of the energy consumed annually. So it's worth switching off the power. This is only bad for inkjet printers, which clean their heads when plugged in, consuming a lot of ink.
    Let's calculate:
    For electricity I pay about 80zł/month or 960zł/year. So the equipment in STAND BY state devours me 96zł/year. A hundred out of pocket :cry: .

    On t.v. they preach various things - most damage to electrical appliances is done at connection.
    Sense makes sense to turn off devices such as laser copiers, etc.


    The biggest losses and savings are in heating :-) .

    It pays to turn off appliances that consume more than 5W in "standby". If you leave home for a few days, it is advisable to turn off everything except the refrigerator.

    Since I (almost) turn off all the RTV equipment, I have some savings but it's always something. Especially since at my place the equipment runs in standby only when I start using it; I turn it off when I go to sleep. And since I am a "lazy person", I turn the whole thing on/off with the remote control :-) . The only device that works all the time and is not turned off is the recorder for known reasons: if I turn it off, I will not record programs :) . Even the router works only when I use the Internet ie a few hours a day and not non-stop 24h/d. And when leaving home, only the refrigerator works. Even watches I turn off.

    Well, that's over-saving. Are you from Scotland perhaps? :D .

    Eeeeeee there it makes sense let them pull electricity from batteries - they are probably energy efficient. :-) .

    No, from PL :-P . On a rechargeable battery the internal clock works without a problem. Why should it take electricity to light up the digits when no one will look at it for a few weeks? And even if it gets erased, what's the problem of setting it?

    The best thing to do is to turn off everything you own so that it works in STAND-BY mode, take a peek at the meter how it works, you can take, say, two measurements of energy consumption on the meter at home at an interval of 30m or thereabouts - and calculate for yourself whether it pays off for you or not. With the help of your last electricity bill, where you will find the exact rate per kilowatt hour.

    In most manuals there is a warning - at permanent interruption of operation - Disconnect from the mains!!! If you leave in Stand-By regime, then the power supply is under full voltage, only separate secondary voltage is blocked.Turn off not for saving, but for fire safety!!! Remember the law of meanness - of all possible unpleasantness will become the one, the damage from which will be the greatest!!!

    You put it wrong : turning off devices currently " unnecessary " is intended both to save cash , and fire considerations . But as it happens in life should not be exaggerated :!: :D

    I meant that the main is defense from fire, not saving kilowatts. Saving on kilowatts not very much, and behold, in the event of a fire, you can lose everything.

    If at my place devours 50 watts , then as if I was not at home all month , I pay about 20 zł for free. It counts differently when you function every day at home ...

    In most manuals there is a warning - when you permanently leave - Disconnect from the Network!!! And you should disconnect not only when you leave for a month, but when you leave for 5-10 minutes. During that time anything can happen. And relatively watts I want to please you - in STAND - BY no device 50W is consumed!!!

    It is apparent that you have not read all the posts in the topic...Look above...I wrote about all the devices, not one.

    To what measure should one be crazy to guess to leave all devices on for a month unattended?

Topic summary

Turning off TVs and set-top boxes can have both safety and energy-saving implications. While unplugging devices can prevent potential fire hazards and damage from electrical surges, it may also lead to component degradation over time, particularly in switched-mode power supplies where capacitors can dry out. Standby power consumption varies, with estimates suggesting that devices in standby mode can consume about 10% of annual energy usage. Users report that turning off devices that consume more than 5W in standby can lead to noticeable savings. However, the primary motivation for unplugging is often fire safety rather than significant energy savings. Recommendations include disconnecting devices when leaving home for extended periods and using remote controls for convenience.
