I have newer 7.5 boards (some with the daughter board, some integrated) and I can tell you first hand they will fail. I have replace 7-8 of them since I bought the game new in 2015? I just bought five for the discount with the intention of keeping two as spares but I ended up having to use them all. Ironically I seem to lose boards right at an update, every single time. Lucky for me so far all failed boards have been the smaller ones but as soon as a larger board goes I'm out on this older system.

I think I replaced a board within the first year I owned it and it has been one here and there ever since. I have to say though, other than the light board issue the game has been rock solid over the years and my pins get played.
