Problem connecting Xbox 360 E via HDMI to Samsung TV

My first guess is that you bought a lemon, and the console is broken. Unfortunately Microsoft doesn’t support 360 hardware anymore. I would suggest you return it for a refund.

Yes, with the same hdmi cable

But the thing is the Xbox does work in others TVs

Hey Alex, how are you today? Hope you're well!

Reset your display settings. To do this:

Remove any discs from the disc tray.

Turn off the console.

Turn on the console.

Note If you are using an Xbox 360 Wireless Controller, turn on the console by using the Guide button on the controller. Make sure that you use the player 1 controller when you do this. The player 1 controller will have the upper-left light illuminated.
As the console starts, on the controller, press and hold Y while pulling the right trigger. The display settings are reset to the default settings, and then the console automatically restarts
