Spare Parts for MC 7000 Controller

Greetings, recently I had an event that water fell on my controller MC 7000 and now a blade of a channel and the play button of one of the decks are failing, why can’t we find the spare parts for this equipment, if Denon has not discontinued this unit, where can I find these spare parts that are not instrument parts that do not have them either, it seems to me that it is not fair to us Denon fans that the equipment spare parts cannot be found overnight

To be fair - overnight parts shopping is a bit of a stretch for any make/model
