No, not a hacker, Just someone who's ISD 2200 receiver decided to die. I located a 4000 receiver at a very good price with no access card. It makes sense to use the access card from my old ISD 2200 in that case. What is the point of buying a receiver with access card? You then end up with two access cards and one functional receiver. The cards seem to be more valuable than some receivers.
DISH is upgrading their smart cards so Scott is probably right. Though I just checked my 5000 and it does not show Dish 500 ready. If you were the original owner of that 2200 you should be a long time existing customer who would qualify for upgrade promotions. You should be able to get a DVR 510 for $99.00 with a 1 year warranty.
I did similar card's transfer for a couple my relatives last months without problem - call CSR and provide your info, tell them your old 2200 is dead, you got from fleamarket other 4000 and your smartcard still the same.
You just have to talk to the right person, but I know that it is possible to put a smart card from one receiver to another because I have done it before to see if the receiver or smart card went bad. They discovered it was a bad smart card.
Dish recently mailed me a new smart card for my 6000......can anyone tell me why they are changing out cards? Are the new cards more secure? Don't really matter, I got the 811/Hd in a box upgrade so my 6000 will probably be going to Ebay.
