I had the same prolem. OK, try this. Try to discharge the AA batteries in some use, flashlight or else,,,,then recharge them, full charge, install the batteriers ...they should work fine....
I read somewhere that canon is able free of charge to correct a shortcircuit that the camera is susceptible to develop in the installation of batteries......But I hope the advise will work...
Remove batteries when not in use.

I am not sure if this will address your problem but it is worth trying.

Make sure the record/playback mode switch is not in an intermediate position. Push it firmly all the way up. Also ensure that the mode button is not between clickstops. Then try to operate the camera

If that does not help, try the following. Take all the batteries out, including the lithium battery which keeps the clock going. Also take the SD memory card out. Leave the camera sit overnight.

Obtain new batteries - conventional alkaline AAs and a lithium type CR1220.

Next day, clean all the contacts for the AA batteries with a cotton-bud and contact cleaner or isopropyl alcohol. Let dry. Then insert the new lithium battery. Next insert the new AAs and try to turn the camera on.

If it works, insert the SD card. If it does not work then there is probably an internal problem and it should be serviced.

are you using NiMh rechargeable batteries?
If yes, check that they are fully charged. If that doesn't do the trick, sounds like it might be a power circuit issue. Samsung is in Secaucus, NJ
or SamsungUSA on the web

akaline batteries wont work

If indeed the batteries are brand new and without a doubt charged,
then you definitely have a hardware problem in the camera.

You're probably going to have to give it in to be serviced.

Hope I helped!
