Hi,
 
The contacts for the left and down cursor may be dirty. Being an un-used device they shouldshouldn't be worn out.

Here is a link to the [guide|2213|ifixit repair guide] for the device.
 
Here is an image taken from the repair guide. I have highlighted which contacts need to be cleaned, both on the board and on the rubber pad. (The rubber pad contacts have a conductive coating which bridges across the contacts on the board, when the button is pressed down completing the electrical circuit)
 
Use a Q-Tip moistened with IPA 90%+ (Isopropyl Alcohol - available at most pharmacies - do not use 'rubbing alcohol' as it is not as effective)

''Take note of the caution issued at Step 9 in the ifixit teardown instructions''
 
Alternatively since you stated that you bought an un-used device, did it come with a warranty at all?
 
If so follow up on getting a warranty repair or replacement as by trying to fix it yourself as shown above, will void any warranty.
 
Hopefully this is of some help.
