I don't know what policies are where you live.
Around here in the United States, we typically have 30 days to return a defective item back to the place of purchase, in order to exchange it for a working unit, or else a refund or credit. Of course, this works best when you walked into a store to purchase your gear. With mail order type stuff, you gotta go through getting a RA or RMA number and shipping it back and waiting for another unit to get sent out.
If they are new, just return it for exchange, it's not worth the grief and hassle of replacing the part. Sending in out for repairs would take at least an additional 2 weeks just in shipping time unless you opt for very expensive rapid international shipping, which is silly since there are runs going from here to at least the UK daily. Once it hits the Service Department, it can take them a bit of time to get to things based on their work load.
Of course, if you do need just the parts you say and you can do the work yourself, you'll need to contact Elation directly, most likely via voice on the phone. They can ship you most parts. There is a real chance that you may have your warranty voided by this repair though, so do keep that in mind. Also, if I have my time zones correct, Elation lags behind you at least 8 hours, so you'll need to time your call appropriately. As your typical workday ends, ours is probably close to beginning.
