LG unlock pin

[ACK]

Hi all I've a LG UF680 V led tv, I haven't setup a pin code but every time I try to update tv channels or removing parent control etc I am asked to input the unlock code. I've tried the 0000 and 1234 but they don't work. Tried p+p+p-p+ that doesn't work nor mute 3 times to reveal a secret menus. Does anyone know of any 4 pin codes that may work?
thanks
