Just re-installed a DSR6000 which was never deactivated but had been disconnected for 6 months. When I go through the setup, it stops at "seaching for Sat signal" . Stays at 0%. Does not find either sat. If I put anpother receiver aT this location, it is fine so it's not the coax. Rebooted, removed and reset card, called DTV and they told me to get a R15. Any ideas on what is happening with this?
