I can't sign in XBOX app on LG TV

Hi Bajusz_k, my name is Joel, I'm here to help you with any problems or questions you may have.

Bajusz_k, I understand the problem you are presenting. In order to try to resolve it, I need to know a little more about it. Could you please tell me exactly which LG TV model you have? Also, could you let me know what subscription you have on your account when you go to the link?

it happened to others it said "something went wrong" I'll try to do it in my tv after school

I got an LG LCD tv, brilliant picture for sky and gaming, like people said really can't fault LG

Issue still occurs for me. TV is LG OLED55E6T TV (firmware version 05.30.15).

When playing 3D blu-ray movies through the X-Box One S blu-ray app, it will play the 2d menus but as soon as the disc switches over to 3D mode, the picture is lost completely with the LG input can't be detected screen soon appearing thereafter. If I unplug
the HDMI cable from the TV and plug it back into the same input the TV will detect the video again.

As explained above, this is probably something that LG would have to solve by replacing the hardware in your TV. It's an incompatibility between the Xbox and TV hardware, but it can't be solved on Xbox's side, as the issue is with the TV itself.

LG will blame MS, because sending out engineers to replace hardware is expensive for them, and they'd rather avoid doing it, but that is the only solution in this case.
