A letter and number error code of E:61:xx , E:62:xx , or E:91:xx is an indication a malfunction has occurred in the camera. To try resolving any of these error codes, power reset the camera back to the original factory specifications.
If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.
NOTE: The xx in the error code represents any random numerical digits and does not contribute to the overall diagnosis of the issue.
