Canon 5d mark ii won't turn on

While shooting video, I changed my card and battery. Turned camera back on and nothing. Changed with another battery and card. Still nothing

Sorry to hear that.
Next thing to do is to remove that coin (Lithium ion) battery and wait for few minutes before placing it back and use a freshly charged battery, a new memory card. Make sure memory card reader door is not damaged and closes fully.
 If still nothing happens, contact Canon' repair center. LINK

  • 7D Mark II camera won't turn on!

    Hello, I just bought a Canon 7D Mark II been using it for about a month. Yesterday I was filming and taking pictures and I had put the camera down for a second and as I looked down at it I noticed an error message with the yellow Caution sign "!". As I brought it up to read it it disappeared and my camera turned off. I tried to turn it on and i seen real quick at the top screen it said err, assuming that meant error. turned it off and on again and nothing. unresponsive! I changed the batteries, changed the SD cards, changed lenses. tried plugging it into my computer... nothing. If someone could please help I would appreciate it! I have lots of work Monday!! Thanks!

    Oh boy.... Not sure if I can help and only just saw your post.
    I don't have a 7DII (yet),  so can only suggest things that have cleared up similar problems with other models.
    The most obvious thing you have probably already tried... Are you certain the batteries are adwquately and properly charged? During first few uses, batteries may not take a full charge and give expected number of shots. I've also seen chargers not work properly, though that's pretty rare.
    Do you have a battery grip on the camera? If so, try removing and reinstalling it. Sometimes I've had a grip get slighly loose and the camera shut down suddenly from lack of any power.
    Not sure if the 7DII's grip has an off/on switch, but some of the other battery grips I've used have had one that was easily bumped to the off position, or even in-between the off and on positions, turing the camera off. That's something else to check, if using a grip and it has a power switch.
    Have you tried a "reboot"? This involves removing all the batteries, turning the camera on and pressing the shutter release button once (won't power up or fire the shutter, this is just to drain all remaining power in the camera). Then turn it off, put batteries back in and turn back on. If it rebooted properly, you should need to reset the date/time. If not, you may need to leave the batteries out for a longer time. This can clear unknown problems, much as rebooting a computer will do. It likely will mean most or all settings are returned to their defaults, though... so be sure to check anything you had set.
    I just looked to see if the 7DII has a user removeable date/time battery and it doesn't appear to. If that's the case, you may not be able to do the "reboot" (aka "hard reset") I described. This is because the cameras without user-removeable button batteries have a semi-permanent battery serving the same purpose, internal and on one of the circuits. These are recharged by the main/rechargeable LP-E6 battery(ies) and provide backup to retain settings, date/time for about 3 months.
    Finally check that the electronic contacts lens to camera and the power contacts for batteries are all clean and unobstructed.
    Hope this helps! Keep us posted.

  • Canon 7D Mark II files won't open in bridge or photoshop

    I am using photoshop CS5 and purchased a canon 7D Mark II and my files won't open. I updated to the photoshop 8.7.1 and my files still won't open. How do I fix this?

    Assuming you mean ACR (Adobe Camera Raw plug-in) 8.7.1, not "Photoshop" what you write makes no sense.
    ACR 8.7.1 needs at least CS6 to run.  You will never be able to open your raw files from that camera directly in CS5.  There will be no further updates for the obsolete, unsupported CS5 applications.
    You have to go the free, stand alone Adobe DNG Converter 8.7.1.  Locate it, download it, install it and then launch and run it on ever folder of raw files to convert them to raw DNGs you can then open in your CS5 setup.

  • My bb 9380 won't turn on while the screen shows one battery sign with red cross mark ( not charging sign )

    my bb 9380 won't turn on while the screen shows one battery sign with red cross mark ( not charging sign ), i think the battery drained and switch it for charging but it will show only not charging sign . i bought this phone before 9 months, whats the solution for this ?

    Hi and Welcome to the Community!
    Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!

    my macair won't turn on. when I try to turn it on, the white screen appears. But instead of the apple logo, there is a flashing folder that has a question mark on it. how do i fix this?

    Try this.
    Erase and Reinstall OS X
    Note: This will delete all data on the disk. Back up important files before continuing.
    Erasing and then reinstalling OS X can give you a fresh start, making your computer exactly as it was whenever you received it from Apple. This can solve various problems such as corrupt system files.
    Shut down the computer by going to Apple () > Shut Down…
    Select Shut Down or allow the computer to shut down automatically.
    Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
    Press the Power Button to turn on the computer.
    Press and hold both the R and Command (⌘) keys on the keyboard until the Recovery partition loads.
    Select Disk Utility and then choose Continue.
    Select your startup disk (Macintosh HD by default) from the left.
    Select the Erase tab.
    Choose the Format pop-up menu and choose Mac OS Extended (Journaled), enter a name for your disk, and then click Erase.
    After the disk is erased, choose Disk Utility > Quit Disk Utility.
    Select Reinstall OS X and then choose Continue.
    Follow the instructions.
    I hope I solved your question.

  • Lightroom (4.3) won't recognize the file type while importing from Canon 5d Mark iii

    Anyone mind helping me trouble shoot why my Lightroom (4.3) won't recognize the file type of my Canon 5D Mark iii ?
    I have seen this in a couple other threads but none of those suggestions worked for me. I am also a Mac user.

    Bomal9 wrote:
    I have Lightroom 4.3 and a Mark iii and cannot import raw files into Lightroom.
    The above contradicts with this:
    Bomal9 wrote:
    I am downloading images through the Canon EOS Utility manager and have to import the photos in a folder into Lightroom.
    So my reading of that is that you ARE importing Raw files from the 5D3 into Lightroom, but having to use a roundabout route to do so. Is that correct? If so, how are you trying to import when you "cannot import raw files into Lightroom", are you using a card reader or direct camera attachment? Have you tried both methods? And what happens when you do try?

  • Computer won't turn on... just shows a flashing file with a question mark

    Hi, I hope someone may be able to help me with my laptop. I had downloaded some TV shows off of iTunes and was watching one of them. My computer froze. I forced it to turn off, and tried to restart it. However, it won't turn on! I just get a grey screen with a flashing file that has a question mark in it. It then turns itself off a few minutes later.
    I have tried taking out the battery, restarting etc.... Does anyone have any ideas? Any help would be much appreciated. We live in the Caribbean so I can't take it to an Apple store.

    Hi. I have the same issue as the guy you previously helped. I listened to your advice about putting the Install DVD in and now all i get on the screen is the apple with the loading circle under it instead of the flashing folder. It's been loading for 2 hours now so i figure it's not going to work. I have the DVD in there too and i don't know how to get it out either.

  • Canon T3i Rebel won't turn on( Intermittently)

    Hi,
    My Canon T3i Rebel sometimes goes off while I am shooting. When I try to get it back, it just won't turn on. Now if I take the memory card and the battery out, leave it overnight and next day re-assemble them and turn it on it MAY or MAY NOT turn on.
    I tried to isolate the scenarios and check where the problem is but couldn't find a cause.
    1. Cannot be a problem with memory cards: I tried using different SD Cards but no avail. Atleast when I take the card out and try to start the camera, it should get turned on with a message 'No Card'. Sometimes it does get turned on, sometimes in doesn't.
    2. Can't be a problem with the battery : I tried using different batteries fully charged, yet the same problem persists.
    3. Can't be a problem with the micro switches: If that was a problem the camera wouldn't get turned on AT ALL. Sometimes it does get turned on.
    I had sent it out for repair to the Canon master service center. They couldn't find any error logs. They changed the PCB, but it did not help either.
    Steps to reproduce:
    1. Turn on the Camera
    2. Use different lenses
    3. Use different modes ' Auto / Manual/Video '. Set the lenses to different modes: 'A/F' and 'Manual Focus'.
    4. Click pictures.
    Error noticed:
    The camera would automatically get turned off at some point of time. Switch on the camera. It wouldn't turn on.
    Turn off the camera, take the battery and cards out and re-assemble them. Switch on the camera. It wouldn't turn on.
    Take the card and battery out. Leave it overnight. Re-assemble them. Switch on the camera. It MIGHT nor MIGHT NOT turn on.
    I bought this camera from amazon usa. It has 3 years US and Canada warranty. I am using this in India, so I am not able to avail the warranty.
    Please help. 

    Hi ozkucur.
    Yeah, I luckily did manage to get this resolved. There was an internal loose connection at some contact point with the SD card unit. The service center guy noticed this after I resent it for repair.They fixed it and finally my camera is working.
    They had initially re-placed the PCB unit box but that didn't help. They had forgotten to check the loose contact that was there which was actually causing the issue. I ended up spending Rs 5700 i.e. approx equal to $93. But it doesn't matter now. I m happy that my camera is finally working. It's a huge relief.
    You too might be having a similar problem. Ask the repair guy to check and fix all the contact points and do a rigourous testing. It should sort out the problem. Hope this helps.

  • IMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.

    iMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.
    Help.

    Your iMac is actually turning ON as proven by the grey folder with the flashing question mark.
    The flashing question mark indicates that your system is unable to find a bootable volume. The clicking sound that you hear is probably coming from your hard drive while it tries to recalibrate. I suspect your hard drive has failed.
    What model imac do you have? If it's under warranty I suggest taking it in for service. Hopefully you've been maintaining a regular backup of your data as all users should. I lost my data once and it was a valuable lesson. I back up regularily now.
    If your iMac came with install disks then you can boot from them, choose your language when asked, then pull down the Utilities menu to launch the Disk Utility application. The Disk Utility application will allow you to verify whether your hard drive has an issue. Usually a clicking sound, assuming it's coming from the hard drive, is a sign of a bad hard drive.
    If your system has Lion installed then you can hold down the Command and R keys when you restart the system, then launch the Disk Utility application from the menu that appears.

    I am having some huge problems with my colorspace settings. Every time I upload my raw files from my Canon 5D mark II or 6D the pics are perfect in color. That includes the back of my camera, the pic viewer on my macbook pro, and previews. They even look normal when I first open them in photoshop. I will edit, save, and then realize once i've sent it to myself to test the color is WAY off. This only happens in photoshop. I've read some forums and have tried different things, but it seems to be making it worse. PLEASE HELP! Even viewing the saved image on the mac's pic viewer is way off once i've edited in photoshop. I am having to adjust all my colors by emailing myself to test. Its just getting ridiculous.

    Check the color space in camera raw, the options are in the link at the bottom of the dialog box. Then when saving make sure you save it to the srgb color space when sending to others. Not all programs understand color space and or will default to srgb. That won't necessarily mean it will be accurate, but it will put it in the ballpark. Using save for web will use the srgb color space.

  • My iPod Classic 160 is in disc mode and won't turn off, itunes doesn't recognize it - ¿how can I make it work again?

    My iPod Classic 160 is in disc mode.  I responds to nothing.  iTunes doesn't recognize it.  It doesn't sync.  I've tried to restore and got error 1429.  Now it just stays in disc mode and won't turn off.  I'm keeping it connected to the charger so it doesn't go dead.  Is there anything I can do to resurrect my pod?

    To get out of disk mode do a iPod Hard Reset.
    Toggle the Hold switch till you dont see the red mark.
    Press Menu and Center buttons simultaneously for about 10 secs till the Apple logo comes ON then release the buttons
    Select your preferred language.

  • IPod nano won't turn on or be recognized in iTunes or Vista

    We recently upgraded to Windows Vista, so I downloaded iTunes 7.2, then plugged in my ipod which was working fine, then it said it had to be updated, but first I needed to update something in windows vista. So I updated Vista and also looked in the help section for ipod and read this:
    Microsoft has released an update for Windows Vista that addresses a situation where ejecting iPod from Windows Explorer or by using the "Safely Remove Hardware" feature in Windows Vista could corrupt your iPod. Apple recommends Windows Vista customers who own an iPod install this software update. For information on how to install this Microsoft hot fix, refer to the "Update your software" section below. Tip: iPod can always be ejected safely by choosing Eject iPod from the Controls menu within iTunes.
    So, I thought that my ipod would get ruined so I did the "eject ipod" from the control menu in itunes, and after that my ipod never turned on again. What happened, did I do something wrong?
    I did the 5 R's already and it does not turn on. It is not even in my computer (device manager) and its not even being recognized in itunes. It just disappeared and it won't turn on. Please help!!!
    Thanks in advance.

    I'm having a similar problem with my Ipod (40GB, now discontinued) here's my problem:
    My hard drive would spin up and then down and then up and then it would turn off. Also I would turn it on and flip to a song, it would be OK and then if I went to flip to another one the screen would freeze on me for a few seconds, then it would work then continue doing that until I got it to turn off. It did that for a few days and then the other day I turned it on and it wouldn't take me to my music screen and it came up with an Ipod that was dead and a link under it. It did this for a while and now I can't get it to work either, I turn it on now and it comes up with a folder and the apple support website and when I tired restarting it, the screen would come up with a check mark and say "Disk Mode" at the top and "OK to disconnect" below the check mark, and now Itunes doesn't recognize it and the hard drive spins and it goes on acting like iTunes sees it when in truth it doesn't.
    Hope someone can help!

    1) Make sure you have Blackberry Desktop Manager installed.
    http://na.blackberry.com/eng/services/desktop/
    2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
    "c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
    3) The Application Loader Wizard will appear -- click "Next."
    4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
    5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
    NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.
    http://www.blackberryfaq.com/index.php/BlackBerry_Operating_System_Downloads
    Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.
