My H20-600 receiver has been running hot and acting flakey for a while now. This evening I could get channels but after a while they would just become a black screen. Say I was watching 280 and then changed to 306, black screen. Turn the box off and then on again, and its back at 280! Like it never even went to 306. At this point the box is so bad its saying no signal. How can I tell customer service to swap this out? They keep wanting to send a tech out to align my dish. I told the guy about the recall and he said it was a power supply issue. The heatsinks inside are too hot to even touch and the access card has a brown outline of the chip. I'm pretty close to just buying one from ebay at this point.
