Default Does leaving your equipment on shorten it's life span?


If I have turned my receiver on, if I'm at home all day it stays on all day, if I know I will be out for 2hr or longer I will turn the receiver off.

Logic would say yes. If left on, inner components produce heat. That heat will affect said components and their connections to the circuitry.

I think that a more appropriate question would be, “Does leaving your equipment on shorten its life by any noticeable measure?”

For the record, my equipment gets turned off IMMEDIATELY if I know that there is ANY chance that I may be away from it for more than 20 minutes.

Electronics that are in a small inclosed space will overheat but the guy is right if you have adequate ventilation electronics should generally speaking be good.

I have an inexpensive home entertainment centre and it had balsa wood on the back that was just stapled on to the wood, so my Dad and I ripped it off to give everything more ventilation.

Generally, people turn their TVs and other A/V equipment off when they're not in use. That's standard procedure! Why leave them on if you're not using them? Not only you'll be jeopardizing of damaging your components, it's accumulating un-used electricity on your electric bill, that you will have to pay for. For instance: if you leave a water faucet running for hours or days, that unused water is calculating on your meter, and it's accumulating usage on your ultility bill. I think some A/V receivers have a build in Auto Shutoff mechanism to be set at intervals, when the receiver detect it's inactive, but all it takes is 1 second to push the off button on the remote control.

I didn't watch the entire video, but there's two view on this: one is that leaving it on will cause heat that hurts components. (It's also an environmental issue). The opposite is that the surge in electricity when you first turn a component on is the most damaging (don't light bulbs always burn out when you turn the lamp on?)

But quality components will last decades anyway. The biggest problem in components is leaky capacitors and that's independent of whether you turn a component off or not.

I'm still using several components I bought in the 1970's: an Apt-Holman preamp, a Crown power amp and vintage speakers. The preamp has some contact issues, but other than that, they all work perfectly.

My parents had NAD equipment that they bought back in the 80's it died back in the early 2000, 20 years for electronics isn't to bad

I do turn the display off when I am not using it. But generally if its only a 2-6 hour break I will leave the A/V receiver and Blu-ray player on with no audio coming out of course. Very low power used on A/V receivers when no audio is coming out.


However in general electronics can last longer by leaving them on since turning something on and off causes a small surge and running equipment like computers at a constant temperature extends the life. For example I have family members with several desktop computers and they all have been running 24 x 7 for over 10 years when connected to a pure sine wave UPS unit. No problems with the computers that are always at the same internal temperature (sometimes the room temperature can vary 5-10 degrees which changes the internal temperature of the electronics).


But I do turn the display, Blu-ray player, and A/V receiver off when I am not using it for the main purpose of saving electricity. The 2008 Pioneer Elite plasma and 2008 Pioneer Elite A/V receivers that family members are using have been working fine for the last 10 years. Now leaving the display on 24 x 7 all year long in a retail store well result in the light engine burning out faster. Many high-end displays have a light engine life of around 100,000+ hours before the flat panel needs replaced (Some only 60,000 hours, depends on the brand and model).

The real trouble with powering down is heat cycles. Enough of them, off and on, and you'll have issues with solder joints, or other metal joints in general. This is why it is generally recommended to leave a desktop PC on constantly. Mine costs about $4/mo to leave on.

I had no idea that leaving equipment on while not using them for hours was a thing.

I turn my systems off everytime I'm done with it as I see no need for throwing money out the window. The only exception is my Bell Fibe box as its really slow to come up. My AVR's are going on 10+ years and they still work flawlessly.

The peak in rush current when turning AVR is limited to the power supply filter CAPS only and they have been designed to take much much more than what happens in turn on. All other electronics inside an AVR comes after the power supply so they don't see the in rush current.
