I bought an H20-600 last year at Costco. After running it in my living room for a month, I decided to get an additional HDDVR instead, so I replaced the H20 with a HR20. I put the H20 in the basement back in the original box. Fast forward to yesterday. I got a new HDTV for the bedroom. I pulled the H20 out of the box in the basement and reactivated it. Directv was very helpful as normal. However, while I was getting the box online, I was told that this model receiver is being recalled because it suddenly fails. According to the rep I talked to, this model receiver has had sudden failures and the decision was made to replace the boxes with refurbished H21's or a different model of H20. After I got the box online and working, I was forwarded to another department which I had to wait on hold for about 10 minutes. The rep who took my call initially waited on hold with me. When I finally got through, the rep gave all my information to the rep in their "recall" department. I was told what would happen. A box would show up on my doorstep, I would take the refurbished H unit out of the box, and put my H20-600 in the box and ship it back. I wouldn't be charged extra for it so long as I got the return out the door in 30 days. They also said this was a new process and nothing could be shipped for a couple weeks. This tells me this just was started if they are still getting the process down. I don't know if this affects all H20-600s or just certain serial numbers or what. Just that I am affected and if they are recalling my unit, who knows how many units will be recalled. Hope this helps someone.
