Dropped camera zoom lens is stuck

Here are some troubleshooting steps that you can try that may (or may not) correct your problem. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them. And am guessing that your lens may be crooked from the fall, so you may need to progress to Fix 7b first to straighten it before proceeding with the others. Good luck!
