TV Main Board Cross Compatibility?

I have a 60LA7400 with a bad main board.  I am not able to find a replacement but I can find main boards for the 55LA7400 which is essentially the same TV only smaller.  What functionality, if any, will I lose by using the mainboard for the 55" versus the 60"?

    Buddha411 , the functionality would be the same, however, there may be a problem when it comes to voltage.
