Original Xbox 500g No HDMI Signal

W as working fine. Used it offline for a few weeks. Now doesn't transmit a hdmi signal. My wireless controller just flashes constantly. My Xbox turns on, beeps 12 times. Sometimes it beeps twice. Its connected to internet, has excellent power supply. I've
tried most solutions. None work. Do you think I should try a offline system update?

Crushed Blacks, Improper color Gamut, Digital noise using TV with HDMI in

Has anyone at MS acknowledged these issues when using the HDMI in for TV? It is really obvious these are real problems when you compare the HDMI video signal to the original video signal coming out of the Cable box.

Picture quality is pretty clearly degraded passing through the Xbox one.

 

Xbox 360 HDMI to Projector, No Signal (worked before)

I just tried with the original HDMI cable that comes with the xbox, still "No Signal"..

Frustrating. It still works with my parents TV.. And the projector works with my computer..

 

If the console is not transmitting a signal to your TV then it may be an issue with the graphics card. I would suggest a repair of your console. This can be set up at
devicesupport.microsoft.com.

 

Please turn the console off and unplug it for 30 seconds and see if it has the same problem.

Also unplug the power supply for 10 seconds at least, to reset its surge protection.

Next I would suggest you try to get to the troubleshooter menu in pre-boot:

1. Turn off the console and unplug it for 30 seconds at least.

2. Press and Hold the Bind (to connect controllers - it's on the left side of the console in the silver on original xbox one, on the front near the USB port on xbox one S or X) and Eject and then while holding those two buttons turn the console on with the
console's power button.

3. Continue holding the Bind and Eject buttons until you hear 2 power up tones (counting the first one) and then release.

4. At the menu select Reset and keep games and apps. If that does not work please Do it again from Step 1 but Reset erasing everything.

---------

If that does not work please try the USB factory reset here:

Also make sure you've tried these steps for a blank screen:
http://support.xbox.com/xbox-one/system/tv-or-monitor-screen-is-blank-while-connected There's a similar way to the steps above to reset the display settings to 640x480 - make sure you try that.

If all that does not fix it I would recommend you have the console repaired. See here to register your console to see if it's in warranty still:
