PTCL Smart TV Channel Locking

Can somebody explain to me how does one parental lock a channel on Smart TV? It asks for password and I've tried many combinations suggested by the PTCL helpline but it refuses to accept. Whats the magic key?

correct password is the one used in your smart tv configuration and I got this password by PTCL. They sms me the login credential of my smart tv after few days of its installation. Else all the passwords told by their pathetic help line is useless... they had no idea about it.

Go to ur exchange and ask them about it or complain abt it.

I don't about the password of smart tv channel but you cansearch it in google.

Imran, I did search Google ☺ I finally got the correct one from exchange, its a random combination of numbers.
