My 622 went into a constant reboot situation. Sometimes when I pulled the plug for 10 sec and reconnect, it would be corrected. Othertimes it would not be. I called DISH and they sent me a quick replacement receiver. However, this one does the same thing! I did find out that if I disconnect the HDMI cable (which goes into a Lumagen video processor), it would boot up fine and then I could plug the cable back in. Sometimes I have no issues at all, but this all started about a month ago. None of the other equipment has been firmware updated except the 622 which does it automatically. I've never had any issues with this setup. Any ideas?
