Question about Canon PowerShot SD400 / IXUS 50 Digital Camera

1 Answer

Won't Even Turn On

I've had the Powershot SD400 for quite a while with no problems, until about two days ago. I can't turn it on at all! No message, no noise, no nothing. Battery is fully charged, never dropped it, never been wet, never even been shaken. PLEASE help, I am desperate.

    I've had the same problem. It is a great camera and I've used it a lot with absolutely no problems - but it just suddenly refused to power up.

    I have had my canon powershot sd400 for nearly 3 years now and I haven't had one problem with it but 3 days ago it wouldn't turn on. I fully charged the battery but it still wouldn't turn on.

    SD 400 Powershot won't turn on. Camera used to work wonderfully, however I am not happy when I take it back to store and they want $135 to do an estimate of what is wrong. DJL Claremont, CA

    I've had my Canon SD400 for nearly 3 years, and have experienced no problems whatsoever until yesterday, when it wouldn't turn on. A recharged battery doesn't help, no response. I loved that camera ... is it completely dead now?

    I too have had the SD400 for 3 years and suddenly it won't power on even with a recharged battery. The battery/SD card slot cover isn't missing the little piece which some say can cause this problem. The slider is in either the still picture or video position, I hit the power button, the lens extends, the screen comes on with the Canon logo but within 3 seconds the lens retracts, the screen goes black. If I place the selector in the review pictures position and turn it on, there are no problems. I can review the pictures as I normally would. Any suggestions?

    I have had my Canon PowerShot SD400 for 2.5-3 years now. It had always been very reliable, then one day I was snapping pictures one second and it was dead the next. I can't figure out what's wrong with it, I know that it isn't the battery because I went to the camera shop and they tested that.

  • Aaron Klapheck Mar 06, 2009

    I have the exact same problem. It just won't turn on for no apparent reason.

  • five3baby652 Mar 24, 2009

    Its practically brand new, worked for awhile then in my back pocket i took a seat.. felt it jumped up, never turned on since! Ive tried cleaning the battery prongs, reinserting the brand new Fully charged battery. NOTHING! Any suggestions?.. Canons repair estimate is the same as buying a brand new one.. but why would i want too when i already have a camera that is supposably top dollar that cant even withstand one accidental sitting!

I have a Toshiba BDX2100 Blu Ray player. I've owned it since October 2010. I've not had any problems with it until a couple of days ago. It won't turn off unless I unplug it, and it only opens...

Do you have the Blu Ray player plugged into a surge protector, sometimes surge protectors can cause odd feedback in certain electronics and cause them to be buggy. If this is the case, take it off the surge protector and plug it straight into the wall and see if that fixes the problem. If this isn't the case or doesn't solve the problem there could be a number of reasons this is happening, there could have been a surge that fried some internal components causing the player to not function correctly, or it could have just had a hardware malfunction. If this doesn't help I would recommend calling the manufacturer of the player to see if they can provide you with additional info

Canon PowerShot SD400 No memory card message, but there is a memory card installed. Tried multiple memory cards and got the same message. Made sure the memory card was locked.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". Some include trying to use a 4GB SDHC card with an older camera made before SDHC format came out. Others include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at this link. By the way, if you're using 4GB or larger SDHC cards, they won't work with the SD400 as that camera was made before SDHC came out. Consider 2GB or less standard SD cards only. They're very inexpensive these days on Amazon..

Hi. My Canon Powershot sd400 is telling me there is a " memory card error"...and "Card Locked!". Any idea how to fix this? Heidi

You have to unlock your memory card. All memory cards have this small lock mechanism on the side.


Make sure that the slider is on the UNLOCK position. If it's already on the UNLOCK position and you are still getting the same error message, try to set it to LOCK, then set it back to UNLOCK position.

I hope that helps.

Good luck and have a nice day!

Canon SD400 Powershot wont turn on

I read a part solution on your web site about my Canon sd400 failing to start. The message gave a few free words about a micro swith in the cover. I couldnt find it! I called Canon tech and they said there was jo such switch. I packed up the camera and sent it off for a fix and a free firmware update. Probably going to cost $80. But I think it was the right thing to do!!

My Canon Powershot SD400 won't turn on and lense won't go back in

Unfortunately the lens assemblies in these compact digital cameras are quite delicate. The drop probably knocked the barrels of the lens out of alignment preventing it from moving. You can try to GENTLY twist the lens back and forth, you may be able to click it back into alignment allowing it to function normally. If the gentle manipulation fails to fix the problem you will need to get the camera serviced by a professional. There are quality repair services on the web who will work on your camera.
