EOS 70D - Mode Dial problem...

patricio7707 — Sun, 09 Feb 2014 19:42:14 GMT

Hi ... I'm Patricio from Argentina.

One week ago I received from the U.S. a Canon EOS 70D.
It worked ok until yesterday.

Since today, when I want to choose different modes with the dial mode, the camera just sets: P or A+ (auto).

- If I select A+ mode (Auto mode) or "Disabling Flash mode" or "Manual mode" .... the camera sets as A+ (Auto mode).

- If I select modes: CA, SCN, C, B, AV, TV, or P ... the camera sets as "P mode".

I have read some similar cases in other models of EOS cameras ... they recommen do a "hard reset" by removing the main battery and clock battery.
I tried to do that, but this model (EOS 70D) seems to have a battery for the date and clock ... but it is internal, It`s a rechargeable battery.

I guess as a new model, there is no more than the actual firmware, that comes from factory ... so I can`t try to update, since there is no other firmware available.

Anyone have any suggestions before taking it for service?

Thanks!

you can see what's wrong with my 70D here: (the mode selected by the dial, it's not the same on the screen)

I took a look around the WEB and could only find one additional 70D user with the same problem. The suggestion was to remove batteries OVERNIGHT to reset everything.

I also have a 70D and checked mine and it is working as intended. There are canon moderators that come on occasionally and assist with probelms like yours. There are aslo some contributors with a many years of experience that may wade in on this issue. Perhasp someone else can help before you have to take the camera back to canon for servicing.

Have you tried powering off the camera, removing the battery, waiting a minute, re-inserting the battery, and powering it back on?

The on/off switch is really puts the camera into an extended power-saving sleep mode. The camera still technically has power. When you turn on the camera again, the camera really just wakes up -- it does NOT actually re-start or reload the firmware.

If, however, you remove the batteries from the camera, you (mostly) deprive it of power. When you insert the battery and power it up it actually forces the camera to load the stored firmware again... you are in effect "rebooting" the camera when you do this -- the camera does not "reboot" simply by turning the power swtich off and on again.

I did say "mostly" deprive power when you remove the battery because there is a technicality. Depending on the camera body, most cameras have a 2nd battery used to store settings and also maintiain the date/time clock. That battery is either a removable coin size battery OR it's a built-in rechrageable battery which recharges off the regular battery. If you store the camera without a battery for too long, it will prompt you for the date & time when it powers up -- but this means the internal battery was depleted of power.

I *think* your 70D has an internal rechargeable battery. Simply leaving the batteries out over-night will not be enough. Hopefully just re-started the firmware by ejecting and re-inserting the main battery will be enough to fix the problem.

I just turn on the camera after 24 hours since I removed the battery and memory card.

Nothing happened ... the problem persists. The camera din´t ask me to set the date and time... so I understand, the "internal battery" was not discharged.

Dear Patricio,
since yesterday i have nearly the same problem on my 70D. If i want to change to SCN it shows the previous modes correctly [Av -> M -> B -> C], then switches to Av and then to the following modes [CA -> Flash of -> A+]. All other Modes work fine.

Do you still have the problem or could somebody help you?

Kind regards

Daniel

I left my camera in the technical service and they determined it was a malfunction of the mode dial. They had to replace the "top cover".
Now I'm waiting for the camera, refurbished...

sounds bad. I have the 70d for just 5 days now. Is it a know problem by canon?

Yesterday I reset all customizations before sending the camera back to the reseller. The last reset was "return to factory settings" reset. After the camera was resettet to factory settings the SCN Menu appeared as it should!
So I don’t know what leads to this problem, but at the moment the Mode Dial works correct.

Well, good for you!

The truth that what happened to me didn´t make me happy.
Right now I'm hoping Canon notify me when I go to pick up my camera.

Knowing that another had the same problem ... talk about a serious flaw in the design or behavior of the mode dial.
It would have been bad news for me ... because the piece replaced by Canon could fail again.

I hope it's permanent ... and my 70D perform as expected at the outset.

patricio7707 — Sun, 07 Sep 2014 15:39:21 GMT

well .... 5 months later, after replacement of the top cover, I have my 70D finally fully operational.

(5 months of waiting because I live in Argentina and here the Canon Service depends on that Canon Latin America send the parts).

Did they do it in case of warranty or you needed to pay?

Or you just ordered the part and made it yourself?

(how much it cost?)

I bought the camera on a trip I made to USA. I live in Argentina.

The warranty is valid in the country of purchase. I contacted via email with Canon USA and they told me that I take my camera to them, but it was impossible for me.

The camera was repaired by an official agent of Canon here in Argentina.
The total cost was about 150 dollars.

On eBay, the piece is worth about 70-80 dolars.

Im having the same problem rightnow. Canon gave me an estimate of $200 because it is out of warranty. I have had this baby for 3.5 years now and it didnt do this before. Occasionally it would but not for so long.. I have ordered a new battery to see if that would help solve the problem. I cannot send it to canon because 200$ would be too much for just a dial fix, so im gonna try somewhere else where they could probably do it for cheaper.

Hopefully the battery would solve it. Im glad your canon is fixed!

I having this problem. Can anybody solve it ?

Re: EOS 70D - Mode Dial problem...

Did you try to reset to factory settings? This helped me.

JuanLopez — Fri, 15 Dec 2017 22:38:42 GMT

Hi! can you solve it with factory reset? If I don't use the camera for a while and remove the battery it works but some times the problem is back... One year and still 😞

Hello,

I experienced the same issue while repairing a 5D3, it came out that the issue was caused by the top cover flat cable not properly connecting to the main board of the camera. Solved by cleaning with isopropilc alchool the flat contacts. Hope this solution might help someone in the same trouble.
