Hi,
The part is available on [https://www.ebay.com.au/itm/SWITCH-CONTROL-BUTTON-EAX64466302-EBR75421802-LG-42LS3450-42LS345T-32LS3450-TV-/152121030392|Ebay] (it is located in the U.K.)
Just search online using the board number (EAX64466302) for other suppliers if this seller doesn't suit you.
The only test perhaps is to use an Ohmmeter and check if any of the buttons is s/c (short circuit) or low resistance. Although perhaps not because if it was then you would think that there would be a indication on the screen such as a permanent Volume level display in the case of a faulty Volume button for example. Maybe more than one button is faulty which would confuse the processor as to what to do and therefore it would do nothing. Just a thought.
+I don't think that the IR is faulty because it works OK when you disconnect the button board.
