No picture but I have the sound after update

Can you try with a different TV?

Well do you have sound when you use componant cables (Yellow white and red cords) IF you do have sound then try another HDMI cable. See if that solves your issue

Hopefully something in here can help, but it sounds like you have pretty much tried everthing.

I had the same thing happen to an old unit of mine, I tried all the steps you have listed and nothing worked.

Turned out in my case the GPU had died, so it was either repair or replace for me.

Unless someone has some further steps you can try you may need to ring support and order a service/repair.

I had the sound but no picture issue,I had just finished playing titanfall beta & went to go back to the dashboard.

so I pressed the guide button & lost the picture. Had to turn off the xbox & unplug the power supply then it was fine after that.

It is something to do with the update as I had no issues prior to the update & now these issues are starting.

remember the update was delayed & I think this may have been why.

If it is was hardware the picture wouldn't have came back after a display reset or power reset.

& it is funny that all the issues are happening to everybody who has one after the update coincidence I don't think so.

The dvd playback won't work either for my brother in law either, the sound plays but no picture goes back to the dashboard & no picture the power supply trick fixed it for him also.

The issue/s need to be fixed as this is ridiculous that an update can cause this much damage.

Hi, did you try everything on the link below. in particular the display reset ?

support.xbox.com/.../tv-or-monitor-screen-is-blank-while-connected

1.If there's a disc in the Xbox One console, eject it.

2.On the console, press and hold the Xbox button for five seconds to turn off the console.

3.Press and hold the Xbox button and the Eject button until you hear a beep to turn on the console. You will hear one beep right away and a second beep 10 seconds later. The power light will flash on before the second beep. DO NOT LET GO until the second
beep occurs.

Note This will boot your console in low resolution mode (640 × 480). To reset this setting, go to Settings in the guide, select Display & sounds, Video options, and then TV Resolution.

Maybe also try a different HDMI port on the TV.
