My 60D (with ML installed) stopped working whilst I was taking photos - it showed err 80 on the LCD. Since then, the only sign of life from it was it once flashed an empty battery symbol on the LCD. I have tried all combinations of lens attached/removed and new batteries with/without old and new SD cards (both bootable and non-bootable) and the camera shows no outward response. The camera does not respond to the portable display test or LED blink test.
Any suggestions?
