The wife fired up the ole' 510 last night and 10 seconds later it freaks out, makes a wierd clicking sound reboots numerous times then flashes an error message with error code: 04b2 "Serious HD problem call Dish". Just called dish, gave them that code and the csr promptly said "Your new 510 will be shipped out today". No questions, no telling me to reboot, pull plug, etc. Oh well, thank God for the service plan.
