7d telling me there is an external flash attached when there isnt....how to fix?

[dondada]

I used a led light mounted in the flash mount, there are no metal contacts on this light, however after removing it the built in flash will not open. When i go to flash settings, it is telling me there is an incompatable flash mounted. How do i fix this?

There is a micro-switch in the flash mount on the camera. It senses if something is installed in the flash mount and turns off the internal flash. It might have become stuck.
