No. The A610 works with MMC and SD cards, 2GB or smaller. It will not work with higher-capacity SDHC cards.

Hope this helps you. Thanks for using FixYa.

I suppose you tried pressing the "display" button a few times to go through the dispay options (one of which is to not show anything ...)

Things to check first are battery contact points, and micro switches that are located on the battery and memory card doors. Details on what needs to be checked may be seen here. It won't work for every case, but it's worth a try.

This behavior comes when the camera is confused about whether the flip-screen is snapped into the camera screen out or screen in (for protection). The screen is supposed to turn off automatically when you snap it into the camera-back screen down. But if you flip and twist it in a certain way, the camera gets confused. I'll bet that if you keep your screen out, on the side of the camera, you can take pictures just as well as ever. To fix the problem, flip the screen out with the camera on, then rotate it all the different ways you can which allow you to close it with the face out. One of the orientations will leave the screen on, I believe. At least this procedure is the one I followed on my A610 to fix the same problem.

Try the solution posted by frozen80 at http://www.fixya.com/support/t295396-canon_s2_black_screen. It fixed my Canon PowerShot A610 black screen (closed diaphragm) problem.

No luck so far. some idiot copied an pasted my posting as a solution. thats it so far. if ya figure it out let me know

you will need a #0 screwdriver. 1. remove the screws on the sides two on one side three under the Digital/dc in / av out 2. removed the screws from inside the battery compartment three total screws Cheers! PS these are small screws. Work in a well lit area!

Junk in the usb mini connector could be shorting the main board out. Try a can of electronics duster in the port. Cheers!
