I picked up a used 5900 for $10 at a garage sale and havenít yet called it in to activate it. I plan on using it in the kids room as itís the last old crt tv we have. After I plugged it in Iím getting a smart card not authorized for this receiver message. I pulled the card and it does match the system info screen as correct. Not sure why it would display that. Iíll phone it in and see what happens I guess.
