GuruHi.
Unfortunately there is no magic code that you can enter to undo the pin code lock.
This is how its done but you will need A repair shop to do it.
Place set in to protect by entering any sequence of numbers 3 times,
Connect a 390ohm resistor between w129 (ground) and pin 56 of the micro,
Press button 7 on the remote for a minimum of 6 secs.
And thats it unlocked.
Sorry its not a simple fix.
