What product is your remote control associated with?
is it a universal remote? is it the remote that came with the device. ie TV, Blu-ray player,
If your remote is the remote commander that came with your TV or blu-ray player
all that is required is battery power, and an unobstructed line of sight path to the device.
make sure there is nothing in front of the product such as knick nacks if on an entertainment system.
or books,magazines or other items if on a table.
If the remote still does not function, do you have other sony products? the remote for our Televisions will power our Blu-ray players natively without any further programming. If there is no response from the remote at all please contact support for more options.
