I just read through a bunch of threads regarding HBO and DirecTV. I got a call from a client today asking me if I could meet the DirecTV Service Tech at his house to help troubleshoot the problem. When I arrived the Tech began telling me everything he had done so far to try and figure out why the TV (new Sony XBR-65HX929 - Couple months old) would flash the picture (go black for a half a second) It looked like a very short HDMI handshake kind of thing that would happen in no specific pattern. Sometimes every couple seconds and sometimes every five or ten minutes. This all started when the customers original DirecTV receiver took a crap and they installed 2 new HR-24s in his house a couple weeks ago. The tech switched those boxes and the box with the problem acted fine on the older TV while the box from the older TV picked up doing exactly what the other one was doing. I removed everything from the system except for the HR-24 to the TV direct via the Existing HDMI cable and the problem continued. I then switched to a new input on the TV and used a new HDMI cable that passed Bluray 1080P without problem only to find the problem continued. HR24 has the latest update and the XBR firmware is current. Happens on all resolutions and resolution is currently locked on 1080i. Any Ideas???? This is 100% an HDCP issue in my opinion. Keep in mind we might have 10 seconds of clearly playing movie before 1/2 second black screen flash or we might have 10 or 15 minutes between happenings. The TV authenticates every time and never an error. This is a strange hiccup in the constant handshake process that goes like this. 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good 2 Sec.) Bad (Black flash) 2 Sec.) Good 2 Sec.) Good (Minutes Later) 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good 2 Sec.) Bad (Black flash) 2 Sec.) Good 2 Sec.) Good 2 Sec.) Good Its 100% a DirecTV thing but I want to know what exactly is going on, why its going on and what they are doing to fix it. Or at least that they are working on it and not just telling people to use a format that officially died in January and is not even available on most new equipment. Anybody have any insight? PS. if this thread is in the wrong place please feel free to move it.
