Strangley, both my Nokia Dbox 2 and mothers Dbox2 have both stopped working with their respective remote controls. The remotes work on others Dbox's, but not these - anyone know how to fix this problem please? Has the Sensor in the Dbox gone kuput! Are these easily replaced / worthwhile in terms of cost - or is it down to the case of getting a new box!? any help much appreciated!
