Quick menu is jumping on ISO

I turn on my camera and the first thing thats appears on my screen is the iso. (normally, the quick menu is the first thing). So i select the iso, and put ok, and the iso cames back to choose again and i hit ok, and this happens again and over and over, doing this so many times. So it seems like my button is pressed on iso, but is not. So i change my dial program to another M or P or Macro, and it comes back on this. It is annoying because i choose iso 400 so the iso comes and popup on my screen many times and sometimes changes to another iso.

I have reseted all options, update the firmware, remove the batery, replace to another card, and the menu goes crazy.

But this happens on photo, on video, on live preview or on visor. I pressed all buttons to push if something happens to them, but for some seconds stops, and when i try to take a picture, it goes crazy again!

This happens more on the Iso, but i saw changing others thinks like aperture... i really don't know what is going on... any clue?

Thanks :)

Most likely, the [ISO] button (on the top of the camera next to the mode dial) is stuck, so it remains depressed even if you don't press it.

Buttons sometimes get stuck, either due to dust or dirt getting in, or because of mechanical damage. I've seen one case where a button got stuck due to a splash of sugary soft drink ;)

Check how the button responds to being pressed. It should have a little "snap" when you press it, if it does not, the button is likely stuck or damaged.

The issue can likely be resolved by cleaning, but this requires dismantling of the camera top panel. There isn't currently a guide on ifixit for the correct procedure, and I do not have a 650D/T4i in my possession to investigate, therefore regrettably I cannot point you to any details.

At this point I'd advise to take the camera to a repair shop and ask for a quote.
