Where do you guys go for professional repairs? My warranty is expired, so I bet it will cost a fortune to get it fixed by the manufacturer (Sony). Is there a trustworthy chain that does camera repairs?
Repair shops that come to mind are electronic and gadget stores. A better option would be going to a camera shop since they'll have specialized knowledge about the device.
I'm sure all major brands have the option of troubleshooting issues online. I know Canon does. If you do this, you would have information to give a repair technician to expedite the process.
I've used the Geek Squad before at Best Buy, but that was a long time ago. Their work was good and quick, so you might check there if they still work on cameras.
I haven't had to do this yet, but I would probably get in touch with the manufacturer. If they don't do it themselves, they would probably have authorized repair businesses that are affiliated with them.
