Trekkie, hate to say it, but that does sound like something died in the 990. I understand you to mean the 990 shuts down and there's not video or audio. Does the 990 come on again for 3-5 seconds, or is it totally dead after the first episode? I have heard of losing a fuse which could be the case if the unit does not power on at all now, but otherwise this sounds like it will need Outlaw service - suggest contacting them.
