I have Magic Lantern pre0.2.2 on my 500D Canon Camera. It worked fine for about a month and it was fantastic. But i had begun to notice that the camera screen wouldn't appear when it was turned on, to which i turned it off and took the battery / sd card out. and then it would work fine.
Now it won't even turn on -even with a full battery. My computer notices the card when its attached to it but when the whole camera is attached it is not responsive. Before the camera died the screen was blank and the shutter would go in and out of focus but not take a photo.
I'm a but stumped about what to do and gutted because i need my camera for work. Any help would be greatly appreciated.
