Having problems with your Digital Cameras ?

I was shooting yesterday with Canon 50D & a lens 18-55 & the camera started to give me error code 20; telling me switch OFF & ON or re-install your battery. i removed the battery & put it again, then i removed it & put another one. it kept doing that error 20 every 2 continues shots & i didn't know what to do ?! Pls advice Thanks



Answers :

Error 20 didn't show up on a 50D error code search, however I've run into this before when the processing operation couldn't be completed meaning the memory card was corrupt.

The Canon 50D makes massively large files and several things can run you into problems the first I doubt but need to list and that is you are using a card with a slow write speed. Another is that you have been using that trash can icon and not formatting your memory card. The trash can deletes files yes but it leaves what I cal a residue (small amount of data) do this enough and your card fills with useless data. Still looking at the memory card, you possibly downloaded pictures to the computer and formatted the card in the computer, not a good thing to do. Error 20 is also a windows error code for corrupt files which will play havoc with your camera firmware.

Another possibility is you downloaded picture files to your computer and forgot to do a safe disconnect, eject or safely remove device what ever your camera computer uses for shut the device off before disconnecting.

After downloading your just placed the memory card back into the camera and maybe started shooting again with a "dirty" card. The correct practice is to format your memory card every time you have had it connected to the computer. Format not delete, format the memory card in the camera it is to be used in.

Clean up the card and your problem will go away. Error 20 is a processing problem, corrupt file(s) or a camera firmware problem. If the problem continues do a firmware update to your camera through the canon site it's free

Every once in awhile, our D90 hangs up and won't autofocus and take pictures. An error message is displayed but can be rectified by removing and putting back in the battery. The battery display usually says it's O.K (at least half full). Is this a battery problem or battery connection problem?


First, clean the battery contacts in the camera with a cotton swab lightly dampened with rubbing alcohol. Then, do the same with the contacts on the camera body and lens where they meet. ... Nikon D90 Digital Camera with 18-105mm lens

PC Mode I have one that for 2 secs maybe, I can see something I could take a picture of.  Problem is that on second 3 the camera screen has switched to saying PC Mode, even though it is most definitely not attached to the computer.  I have tried removing the battery and the cards and putting them back in, and still only get PC Mode.  Someone said something on another board about possibly a reset button, but I don't know if the sony dsc-s50 has one.  Has anybody else had a similar problem, or doe

My Pentax Optio 430RS seems incapable of taking more than one photo before it freezes. Powering off retracts the lens, but then it comes out again immediately, but I'm unable to take a picture. Removing the battery and then putting it or another fully-charged one allows a picture to be taken, but then back to the beginning again.

My Nikon S210 is not focusing correctly. It's just recently started to act in this manner. I had a 'lens error' screen this summer after getting some sand in the lens from my pocket and I beat that one by 100's of 'on' then 'off' attempts and removing the battery when it wouldn't turn off. Literally a couple hundred times over the course of a week and it finally came around and started operating correctly. I've taken maybe 50 pictures since then and kept the camera in it's case when in my pock

I have a canon SD1100 I just purchased and after a few minutes the camera will not shut off, the power button won't work and I have to open the battery cover to turn it off. Somehow this completely drains the battery too every time even if it was just charged. Also the camera turns itself on by itself about 10 minutes after you put the battery in it and once again you can't turn it off. I got another battery and the same thing happens. Otherwise it works fine.


If this is a new camera, you should be running back to the store to return it. ... Canon PowerShot SD1100 IS Digital Camera
