my xbox starts up , no picture on TV

this might not be connected, but if I turn on my TV first then the Xbox I don't get a picture but if I turn on the Xbox then the TV I always get the Xbox start-up screen and everything is good.

it could be that having the TV turn on with the Xbox is causing the TV to start momentarily before the Xbox and it isn't finding the signal.

next time it happens, try cycling through the inputs on your TV so that it rechecks the HDMI input for the Xbox. if it is similar to what happens with my TV then it should show your Xbox screen when you get back to that input source.

Hermes,

I'd also like to add that I have NO DOUBT that the reason the TV app is giving me problems is because it loads too fast on start up. Just like before, the TV app only gives me a bad picture when it is pre-loaded in the main window on start up. The picture
loads fine when the TV app is selected from one of the panels below the main window.

Would you please make your technicians aware of the problem I am having? I am hoping that they will consider slowing down the TV app on start-up so that it has enough time to gather the signal information necessary to display the picture correctly. That
is my only hope of getting things to work again. Thank you.

I have the BT YouView box and all I get is the HUMAX Start up screen cycling between the "Lost TV signal" message on my Xbox. Then after that I get huuuuuuuuuge delay in the picture on the Xbox. Any suggestions?

After further review, I have NO DOUBT that there is nothing wrong with my TV, satellite box, HDMI cables or settings. The problem is definitely the updated XBox One TV app.

How do I know? I noticed that the XBox One TV app never launches in 480p whenever another app besides the TV app is in the main window at start-up. In other words, if the YouTube app was the last app used before the XBox was shut down, the XBox will boot
up with the YouTube app in the main window (not the TV app). In that case, the XBox doesn't need to hurry up and put a live TV picture in the main window at start-up. What I've noticed is that the TV app launches just fine (in 720p) whenever it is not pre-loaded
in the main window and it is selected from one of the smaller windows underneath the main window. That tells me the XBox One isn't giving itself enough time to load the TV app properly at start-up when it's in the main window. Clearly, the system update
was designed to make the TV app load faster than before, but I'm afraid the extra speed causes a flawed picture that is displayed in 480p.

When given enough time to load after start-up, the TV app works fine. That also explains why cutting off the satellite box and cutting it back on again upgrades the corrupted 480p picture to 720p instantly. It's just giving the XBox more time to load the
TV app, and then re-sending the signal from the satellite box after it does.

In conclusion, The TV app needs to be updated again to fix this problem.

My xbox one wont turn on all the way. It starts for a couple seconds then shuts off. No picture on my tv pops up and the power supply ligjt changes color like its supposed to, whote when the xbox TRIES to turn on and orange when it's off.
