I have a LG 50ln5400 tv with the main board faulty and cannot find a changeover board, can i use a 39ln5400 board and change the software. This is an Australian tv and the boards on the shop jimmy are different.
Brian Hill never a good idea to try and make boards fit. You eventually will run into trouble with that and something will not work. Thee is always a chance that the particular board you have may actually be compatible. For that you will have to give us the numbers of the board. Should be something like EBT62359778 (EAX65049104(1.0)). When in doubt post some images of your board with your question. Use this guide Adding images to an existing question for that The main board for the 50LN5400 is always available somewhere like this or even better on here
