consider doing a factory default reset...
This is a response I got back from the Canon tech service people about resetting Becky's SL1 to factory settings:
1. Make sure the camera is off, and then remove the battery, memory card, and lens.
2. Close the battery/memory card doors.
3. Turn the power switch to the "ON" position, and then press and hold down the shutter button for 10 seconds.
4. Release the shutter button, reinsert the battery, memory card, and attach the lens.
5. Power the camera on.
If the camera does not respond to the power reset then we recommend sending it in for evaluation. Canon cameras come with a 1 year warranty from the date of purchase for manufacturer defects. The following instructions will outline the how to send the camera in for service.
Though I don't know for sure, I would guess this would work for the 60D. You can try the "restore to factory settings" first to see if that works: http://www.mahalo.com …dslr-to-default-settings/ as Will suggested.
