When I turn on my camera I get a message that says "lens error restart camera" and the lens won't open. How can I fix this?

I took a lot of pictures on a trip, and when I returned home and tried to take a photo the flash wouldn't work.

Try testing the memory card in another device. If the memory card works in another device, the problem is likely the memory card slot. You will need to replace the memory card slot. Check out the full troubleshooting guide for more information.
