Access the service menu and enable features only available on high end models.
WARNING: Use caution when changing setting as it could become unusable.


Required Items:
2 IR LED's (Can be taken from on old remote) See Image
3.5mm headphone jack (Old headphones cable will work.) See Image
Device that can play an MP3 File (iPhone, iPod, MP3)
Original Remote that came with your TV (Universal Remote will not work)

With this tutorial you will be able to access the hidden service menu on LG TV's (See List At The Bottom).
Once in this menu you can enable features on your TV that are normally disabled from the factory or only available in high end models.

This works by sending the required service codes to the TV with a simple improvised IR transmitter by playing a special file through the LED from an old TV remote.
