5D mk2 wont turn on and off
« on: August 16, 2014, 05:05:21 PM »
Hi there bought a nearby new body (12000 shots). It was working perfectly. New os was installed. No scratches, no dust. Now i am on vaccation and After a few shots the Cam wont turn on anymore. :-(
LCD is empty, Display is Black, while the backlight of the back Display is still Lightning. No Button is doing anything
I've tried the following:

Turned off, removed both batteries, removed cf Card, removed objective (used another one). Turned on and off a few Times, pulled the trigger a few Times, keeped the tiny battery some hours out of the Cam. Put both batteries back again, closed the battery DOOR.

After closing the battery DOOR - while the Cam was still Turned off - the backlight Display started lightning and i Heard- a Short Sound from the objective. So i tried to turn on the Camera back again, but the Display keeped Black (with the backlight on). The top LCD was also empty.


What can i do else?

Thanks you very much in advance

Sometimes a defective battery can do weird things.... if the current or voltage is insufficient you can have some stuff that works and other stuff that does not.

I would say make one last ditch attempt....

remove both batteries for a day.
make sure your battery is fully charged, or better yet, borrow a known good battery.
make sure your cmos battery has decent voltage.

Then put everything in and try again... and if it fails, call Canon.
The best camera is the one in your hands

Ok. I try it once again. With a new battery on monday. And Post My results here. I "tasted" the battery (tongue Test) and its blizzing. But you can be right, the Cam is approx. 4 years old, so the batt can be the issue...
Thanks for your Support!

Its very unlikely to be a battery, the LCD turns on when the switch is off?

It sounds like a short somewhere.  I'd avoid putting a battery in it until a repair shop looks it over.

Yes the Display backlight is Lightning when Turned off. Very strange. The Cam has Never Seen any drop of any liquid.

Why ?

Why shouldn't someone with a problem with Canon equipment seek advice from the Canon community on CR ? There's a lot of experience here.

When the mirror fell out of my 5D I asked if anyone had tried fixing it themselves.

(OK so the best answer was ' you now have the FF mirrorless that everyone is waiting for' but what the hell  ;). )

i think he means this is the rumours>eos bodies section, as opposed to the slightly more appropriate gear talk-bodies section. no matter, mods will move it if they want.

sounds like you have a switch or wiring problem. dont put batteries in it, last thing you want is a lose wire shorting to something else. most obvious answer would be the power switch. its not turning off or on completely. send it in.

It was working perfectly. New os was installed.

New OS=new firmware?

Was it working perfectly before or after the "new os" was installed?

Not knowing, I'd guess a firmware problem.

I suspect you will have to send it in for repair. If you are in the USA, becoming a member of CPS if you have the points will take out some of the bill sting.
