Sony Alpha 65 camera

My Sony Alpha 65 starts to come on with alpha symbol then message camera error. Contactors, batteries, as cards, and lenses are okay. Can the shutter be fixed at home? How do you replace shutter and anyone know about how much? This camera has taken phenomenal photos of motocross, soccer, wakeboarding, stills, portrait, action, and animals. Very worried about the cost to repair. Any advice??
