The switch stuff could have happened from the jostling in transit. I have seen my friend's NIB IM come from the factory with minor switch problems that required soldering. You will always have switches, mechs, flippers, and coils to fix on a pin. NIB, HUO, HEP, whatever, that is just the nature of the beast.
The playfield crack is the million dollar question, and different all together. I don't know or have any good answers. I would guess your options are:
1. Send the game back, get another one. I don't know if shipping was involved, but that is a lot of money if it was. Have no idea the cost/loss on this option. Price Guess: 400-1000 bucks. (Not counting that Cointaker/Stern would have to sell it as a floor machine. So that might be something they might not consider.)
2. Send you a new playfield and have somebody replace it for you. Probably would probably void any future warranties. Price Guess: 1700 - 2000 bucks. Sorry,not a viable option.
3. Partial refund? Depends if you can live with the crack. (Probably the solution Cointaker/Stern would be the most open to)
I am sure there are some options I could have missed.
Just curious, what options have been discussed between you and them? They are probably silent as they do not know how to handle it.
I wish you well and best of luck.
