You could try the like of
Ebay
for a replacement.
S*y will charge around £65 to replace it with a refurbished box that's guaranteed for 90 days!
You get to keep your old receiver though.
Whatever you do you have to get your card paired with the new receiver.
P.S. I see someone is trying to sell this information on
Ebay
for 99p a hit. They want to tell you to call out S*y for a replacement - LOL
