Flashing blue light on back of camera and it won't turn on

Battery is fully charged, but only the faint blue light flashes. Could this be a motherboard failure?

The little blue light on the bottom of the back side of the camera is the memory access light. As long as the light is on, or is flickering, you should not open the battery cover or the memory cover. You definitely should not remove the battery or the memory card as well.
If the light is flashing, it can indicate the camera has problems accessing the memory.
If it continues, you should switch of the camera and remove the card. Then check in an external memory card reader if all pictures are still there. Get all pictures from the card and backup to a computer. Then do a format depending on the size of the card, FAT12 FAT16 or FAT32. Replace the card and let the camera format the card again.
If you do have another memory card, first save all pictures to the computer, only then put the card in your camera to check if that card works better in your camera.
If you need to recover pictures from your card, because the computer can't read them, there are enough recover programmes around on the net. Lots are free.

    Hi Harrie. That doesn't seem to be the problem. I pulled pictures off the card quite easily. The faint blue flashing light is coming from the button under the AV button. If I'm in video mode, it's the record button. Currently, it is not flashing when I turn the camera to "on". In other words, the camera is dead. Absolutely nothing happens and the battery is fully charged. Perplexed, quite!

  • Harrie Jan 30, 2014

    The blue light in that button, is supposed to light only when you are prepairing for direct printing pictures from your camera with PictBridge. (I don't know anyone who has ever used that)

  • Harrie Jan 30, 2014

    The light only should go on, when you connect to a printer.

  • Harrie Jan 30, 2014

    Add a CommentDid you connect anything to the USB connector recentely? because if you did, carfully check is nothing went wrong in the connector. Something broke? something got stuck in there? Could be the camera thinks an USB cable is connected and in the same moment it won't work as you expect. No shooting when the camera is connected.

    Have never connected to a printer and wasn't connected to a USB. We were on vacation when it just wouldn't go on and that blue light started flashing. Only when I took the battery out did the blue light stop flashing. So very confusing.

SOURCE: Battery Fully Charged Camera Won't turn on

Hi

There are several things that could cause this.

1- Check the battery door indicator switch under the battery door and beside the memory card slot. Is the little black switch damaged or missing? Try pressing down gently using a pen it with the door open and then press the power button. Does it turn on?

2- The fuse has blown and needs to be replaced. Offhand I don't recall where it is on the SD600 PCB or how hard it is to solder on a new one (depends on if its tricky to get at or not). Good thing is fuses are really cheap.

3- Other power problem with the PCB due to corrosion or impact damage. The PCB or 'motherboard' of the camera will need to be replaced.

A couple solutions would be to either buy a defective camera online and make one good camera from the two if you can do that sort of thing yourself, or secondly have it repaired by somebody.

Don't bother trying to send the camera to Canon if it is out or warranty (though you can call them and verify what I'm about to say) because they will want $150+ to do the repair for you. Parts are not cheap to buy from them.

I know of one very affordable digital camera repair business... because I own it. The name is Darntoothysam, feel free to check us out, we are on that big auction website also (I don't plug their name for free), our seller ID is 'darntoothysam'. If you Google "darntoothysam" you will find us.

If we can help with your repair then please let us know.

Hope this helps,

Thomas

This is usually caused by a defective shutter release switch - it'll have to go into a repair shop - independent shops will charge about $110 USD - Canon charges about $180

SOURCE: my 40d does not turn on, battery was fully charged

You may need to remove the battery and use a screwdriver to scratch the battery contact point in the camera. It may have been coated or corroded.

Have a look at CNET.COM
I have the same camera and the same fault. CNET are suggesting Canon should recall the camera because of this fault. I did see elsewhere on the net that it was a battery contact problem and a home-made modification could fix it. The camera takes great pictures but I can only use it if I have a batch of fully charged cells with me, and keep changing them. If I go out I take my Olympus or Fuji with me.

Why doesn't my battery charge? Why doesn't the charger's light come on?

Hi Suzanne! Follow these steps to check that your charger and battery are working properly.

1. Unplug the charger for at least 30 seconds.
2. Plug the charger back in. The blue light on the charger should flash once.

If the blue light flashes once this is an indication that the charger is still functioning properly. If the blue light does not flash, the charger will need to be replaced. Follow this link to order a replacement charger. LiNX Battery Charger

3. Place the battery in the vacuum and turn it on for 30 seconds. (even if it does not turn on or powers off)
4. Turn the vacuum off.
5. Remove the battery and place it in the charger.

If the light on the charger is solid blue this is an indication that the battery has been reset. Allow 3-4 hours for the battery to fully charge. The blue light will start to blink slowly to indicate the battery is fully charged.

If the light on the charger is flashing blue or there is no light at all this can mean that your battery needs to be replaced. Follow the link to order a replacement battery. LiNX Lithium Ion Battery

Hope this helps!

Flashing led's on battery pack

Charles,
The battery turns on steadily or blinks to indicate battery charge status.
If the computer is connected to an electrical outlet, the light operates as follows:
  • Solid blue - The battery is charging.
  • Flashing blue - The battery is almost fully charged.
If the computer is running on a battery, the light operates as follows:
  • Off - The battery is adequately charged, or the computer is turned off.
  • Flashing orange - The battery charge is low.
  • Solid orange - The battery charge is critically low
Thank You,
