Xbox One X showing "no signal" when powered on

Have already done all of that, this didn't help.

Have you used the TV remote SOURCE button to select the correct HDMI input, e.g.

HDMI 1, HDMI 2 that your console is connected to?

Yeah i have made sure of that

Hello There ! I recommend resetting the console's display settings. Here's how:

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 System > Settings in the guide, select Display & sounds, Video options, and then TV Resolution.
   
4. If you are required to complete these steps on every boot-up, you will want to change your TV connection to HDMI as shown in step 3 in the next section, "Your screen is blank and you use an AVR in your setup." For more information, see How to adjust the display settings on your Xbox One console.

Same problem here. Haven't found a solution yet.
