Directv X1 TV signal was lost

That helped me -

I have sockets for hdmi one above another on the back side of TV

I saw that solution with hdmi splitter is advertised as it helped -

Logically thinking about their solution gave me an idea that one hdmi channel sygnal intefere with another (could be).

I put a coin(any metallic thing also ok) on the lower plug where it plugs to TV in order to prevent suggested noise to reach another one... and it helped.

XBox started without any problem.

No problem! Thanks for your patience on this.

For now your work around may the best option but our OneGuide team will be made aware of this.

No i am not part of a preview. What is that and what do you need to do?

Confirmed. I have the exact same problem with a Cisco cable box. Exact same timing (last major system update).

I can tell you, I have tried many of the suggested troubleshooting articles, including resetting to default and even reapplying the update offline. So I can save you that effort as it doesn't fix the problem.

Basically, after the update, the xbox has to be fully awake before the cable box is powered on in order for it to detect the signal. I have not found a solution yet.

I have gone thru the tv setup, and it detects the tv and cable box no problem.

I have also tried leaving the directv box on and turning the xbox off and when i turn it back on it again says it lost connection.

As soon as i press the off button on the directv and then back on, the xbox gets the signal.

Anything else?
