The last connection is L, solder a wire to the corresponding point on the logic board Install the mainboard in the player, and reconnect all wires/cables. The installation is now done! Region Searching After connecting the player to Mains, a Blue led should be lit. This indicates that the logic board does not contain region information yet. Power up the player, the Red led will become lit as well. Both the Blue and Red LED are now lit. The Red LED should go off in about 15 seconds. And will start flashing occasionally. If this does not happen, please check the Mainboard connections. A relay on the power section of the LX91 clicks every 20 seconds, and the Red LED will continue to flash occasionally. This indicates its searching for the blu-ray Regions. This can take 1-3 hours. Once the Blue led goes off, the region searching is finished, and region information is stored on the logic board. You can now start using your Multiregion Blu-ray player.
