Canon 5D IV popping noise behind screen when turning on

[SuzukiGS750EZ]

Does anybody elses 5D IV camera make a popping noise like a relay switching or something behind the screen when they turn it on? My camera went in for an 18 point inspection last month and i don't remember if it did this before the service or not.

Is it sensor cleaning.? My 5Dsr does it as do many Canon models. Don't recall hearing a noise tho.

No, it's not sensor cleaning. I turned the sensor cleaning on and off to see if that was the case before posting. This noise is like a light switch in the wall popping. But only when turning on or inserting a battery. Something is energizing and making a popping noise. Just curious if it's normal or not.

Hmm, I'd say not normal. Haven't been conscious of that on any of my Canon bodies.

I have a 5D4. It makes no audible noise when I turn it on; never has. (I have cleaning on.)

You might try cycling the power without a lens mounted or with different lenses, to eliminate the lens as the culprit. I had a defective lens that made a chattering noise on power up. When I changed to a properly functioning lens; no noise.

I have a 5D4 and I do hear a very slight clicking noise when I turn it on. However, I literally have to put my ear to the screen to hear it. I don't think it's sensor cleaning because that occurs when you turn OFF the camera (I hear no noise when turning off the camera). The sound is very slight and I can't hear it, like I said, unless I put my ear physically to the screen.

I can hear the noise from arms length.

I can hear the noise from arms length.

I'd call Canon Support. Something isn't right for sure.

Thanks guys. They issued a return label. I'll send it out Tuesday.

If I remember correctly it was the main board they replaced. If I happen to think about it and find the paperwork I’ll give more detail. It’s been fine since.
