Can a digital camera that has been dropped be repaired?
In theory, yes. In practice, consumer-grade digital cameras are not designed to be repairable, and repairs -- even a diagnosis -- would probably cost you in the same price range as a new camera. If it is a DSLR, contact the service center of the manufacturer for a quote. Normally you will pay for shipping both ways, and a fee for an estimate. They will contact you and have you approve any repairs. Even if you choose not to have them done, you will pay for the estimate.
