Can I Attach the Android TV to an Existing Wall-Mount bracket?
It may be possible to attach the Android TV™ to a previously installed Sony® wall mount bracket. The distance between the mounting holes of the existing wall-mount bracket and the mounting holes on the back of the TV should match. If they don't, we recommend that you purchase a compatible wall mount bracket.  Go to Parts and Accessories.
Some Android TVs require the attachment of extra parts for wall-mounting. To confirm the parts you will need and the measurement of the mounting holes on the back of your TV, check your TV manual. Manuals are posted on your model support page.
