T4i camera completely locking up in the ON position?

I have had my Canon T4i for about 4 months now, use ita few times a week as a hobby. Every couple weeks I will turn on the camera and adjust the Ap/Sh/ISO settings to prepare for a shoot and the camera will just freeze or lock up in the spot. None of the buttons or dials trigger any sort of response from the camera and I am not able to take a picture or do anything. Even turning th camera to the 'OFF' position does nothing and the camera remains on with the LCD still lit up but not responding. The only way I am able to get the camera working again is to remove the battery and then put it back in and power it up, at which point it usually works normally. The only time I've had this happen more than once in a day was over Thanksgiving when it happened about 3-4 times throughout the day.

 

I contacted Canon support and was told to first try resetting the camera to default settings, which I did, and if that doesn't work to remove the battery and memory cards and using a pencil eraser to clean off the contact surfaces of those items, which I have not done yet. If it continues to happen, I am supposed to send it in to let them inspect it and decide if if needs repair or replacement. Since it seems random and spread out, it's hard to say whether it's 'fixed' since it did it last week before I re-set the settings.

 

Has anyone had this problem? If so, did you do either of those methods to solve it? If you sent it in, were they able to determine the problem and handle it? I don't want to send it in and be without my camera for weeks only for them to tell me it worked fine for them and there is no problem, since it works fine 98% of the time as of now.

 

Any help would be great!

I am having a very similar problem. The camera is locked up in movie mode. No buttons respond other than the one that allows me to view photos on the memory card. I cannot even turn it off and too have to remove the battery to shut it down only when I put the battery back, the problem has not changed. I have not reset it yet because I am not sure how. Is that in the menu?

Have you the latest firmware update? If so I would recommend calling Canons customer support and begin the process of having your camera issue corrected, particularly if it is still under warranty. if it is not under the factory warranty and you purchased it with a major credit card you may have an extra year warranty through your credit card company. I have a VISA and when my SD1000 Point and shoot failed a week after my factory warranty expired I simply registered it with VISA sent it in to Canon for repair. I paid the bill and sent VISA the reciept and was reimuursed the full cost of the repair.

Hmm I dont believe I do how can I go about updating it to see if that resolves the issue?

I did the update on mine and that along with my removal of the battery and the lense seems to have fixed my issue.  I've probably taken over 5,000 photos since with no problems.  I'm retired and traveling so I take a lot of photos for sharing and making of photobooks.  The locking up issue was a real nuisance.

 

I'm wondering if this is purely a T4i issue and is significant.  I still see a lot of ads and sales on T3i's and T5i's but never see the T4i mentioned in any sale ads by anyone.

Resetting the camera to its defaults will only change settings in the menu back to their original settings.  There are no settings in the menu that would cause the camera to freeze up like this.

 

Try removing the memory card or using a different card.  You may also want to try cleaning the contacts as suggested when you called us.  If the issue still persists, your camera will need to be serviced by our Factory Service Center.

 

To start your repair process, you'll need to complete a Repair Request on our website.

 

If this is a time sensitive-matter, additional support options are available at Contact Us.

I received a new T4i for Christmas and mine has locked up in the same manner several times over the last couple of weeks.  It seems to happen most when I'm adjusting/changing a setting. I have to pop the battery to get the camera back.  I'll try cleaning the contacts as suggested.  I would never think of that since it's a new camera with new battery and new mem card .
