i am getting some problem with Sony RDR-HXD870 Video Recorder. The code D--- giving me problem, i can't watch any TV when The code D--- is on the display. as i go through the manual i get that this is the parental lock. i try to reset the password, but the problem here is, when i enter the password to "D---", the password is actually of 4 digit but i can only able to enter 3 digit of password. i try to search this on manual but there no information about this in manual, i also tries to resetting the machine. so anyone have any idea how can i solve this issue? this is really annoying now.
