Hi everyone!
Does anyone know how to fix my problem with ISO! (I Think so):dunno
The last time when I set ISO to 3200, I took some pictures then I can't change the ISO anymore, as same as the LCD screen was in black.....I tried to see back my picture, but it can't as well.
However today, when I get out the BIOS battery, just put the main battery in, then I can see the Menu display on the screen, but if I press the ISO button.....It will back to the previous problem! Even if I clear all system and custom setting, Everything is still the same!
Can any one help me please....I really need it to do my assignment!
Thank you and appreciate for all of your help

    Welcome to Dgrin (another member in Australia!:D).

    Can't help with these issues. But someone will, sure! Apart from what you have done already, it's suggested to clear image count. Try also resetting all to factory defaults and then reupload firmware.

    "when I get out the BIOS battery, just put the main battery in, then I can see the Menu display on the screen"

    Does this not happen now? If you have access to the menu you can reset to factory defaults and reinstall firmware.

    Sounds like you need to send it in to Canon. If it's your only body and you've got an important shoot, you're gonna have to rent (or borrow).

    The first thing i would suggest is replacing your CMOS backup battery. When they go bad all sorts of odd things can happen.
