Try the Troubleshooting suggestions at http://bit.ly/2xEVNXq. If none of those work, reset the sound fields per http://bit.ly/2xE8lyi. If the problem persists (or if you require further explanation), you'll have to obtain a walk-through from Sony: use the contact information here--https://www.contacthelp.com/sony./customer-service.
Hope this is useful. Please don't forget to click the Accept This Answer button if you do accept it. My aim is to provide reliable helpful answers, not just a lot of them. See https://www.helpowl.com/profile/Odin.
