1DmkII - Blackout

[pasi]

Hello,

My 1DmkII went black. Nothing happens if I turn power switch.
I have tryed to switch batterys, objectives and memory cards.
I have removed that little battery and changed it to new. Nothing happens.
Does anyone else had problem like this? Any ideas what to do(other than get it in repair)?

ps. I started this same tread ad fredmiranda: http://www.fredmiranda.com/forum/topic/335011

Thanks

I have no experience with teh 1dMkII but my experience with PCs/electronica in general would suggestt aht rather than just taking the batteries out and putting them back in, try the following:
Remove battery.
Remove lense [and put dust cap on for obivous reasons]
Remove button cell battery.
Remove CF card.
Hell, remove anythign you can :)

Set on worktop, leave for half an hour while you ahve a cup of tea with biscuit of choice. Check over any accessories you ahve to see if any of the contacts are dirty or misaligned with the body/lense/battery etc. Watch you don't get crumbs in there now.

Go back, put button cell [preferably the new one] back in.
Put battery [hopefully fully charged, obviously] back in. But nowt else. no CF card, no lense, nowt.

Turn on. See what happens.

A lot of electronic equipment has capacitors to trickle feed to the main boards, and you do have to give them a few seconds [or more - I have seen my PCs BIOS settings stay teh same for up to a minute with teh battery out] to fully lose any settings that might be causing problems.

Hence even if you have changed batteries, for something like this, leave it off for a good while before reinserting, that guarentees that it will fully reset.

If that doesnt work, I'd suggest getting it sent back to vendor/warranty folks and getting it looked at professionally.

If it works, then try adding the CF card, then a lense without the CF card, then the lense AND CF card, etc to try to work out where it is falling over.

As I say thats more experience with complex electronics than with cameras per se, but cameras are complex electronics so the basic rules still apply overall. Remove ALL power sources, ALL accesories, leave for half an hour, and 'bare boot' the item with no accessories at all. then troubleshoot from thereon in.

HTH :)

NB: You havent left the CF door slightly open have you...? Don't know if that affects the 1DMkII....it bloody well does on my 300D...

Thanks Steven,

I will remove battery and all things for a half an hour. Let see what happens.

About that CF/SD door, I though first it was that, but I have pushed it and tryed to close/open it many times. It seems to work like it should. If thats problem I am wery relieved.

[StevenRaith]

In fairness even if it is the CF door switch, I'm knackered if I can see it on my 300D - so it would still proably have to go in for repair anyway.

You got warranty, etc? If leaving it dry for 30mins doesnt do out, then just send it off :)

30 min trick didnt help. Actually dont have anymore warranty, camera is like more than one year old. But fortunately I got assurance on that.

Ok, my camera is now in Canon, let see what happens. From whole ****in Finland there was no 1DmkII or n-models, so now I own 5D for a back-up camera and for primary camera during repair time.

Let see how that stinky 5D works, now out to shooooooot!

[ghocking]

The same happened on my 5D when the shutter went, the camera powered down and that was it, nothing, would not power up again, tried all the same things as you did. I took the the electronics had gone as well. I was lucky in that it was only 3 weeks old so got a replacement in 3 days.
