LG TV mobos interchangeable?-EAX61742609 (4)-EAX61742605 (2)

[LeWins]

Greetings!

I need to replace the motherboard for a LG 47LE5500-ZA ( EAX61742609 (4) ) and I have an opportunity to swap it with an mobo of an LG 47LE5900-ZA ( EAX61742605 (2) )
Physically these mobos are nearly identical. Sofar I didn’t find any information about the interchangeability… but (sofar) I don’t see why it wouldn’t work.

Any ideas?
