Xbox One No Signal Detected is a common issue we hear about here at In this video, we share how to fix the infamous XBOX ONE S Black Screen of Death Issue (No video output) by replacing a failed HDMI Retimer. This video shows you step by step how to fix this issue from undoing the first screw to tightening the last.

Oh dear, no display, nothing..

I know how you feel.   You have just switched on your Xbox One for another gaming session your TV displays a dreaded “xbox one no signal detected” message.  You check power and the source on your TV and it sure is connected correctly, but nothing.. Xbox One no signal detected is all you see.

Unfortunately, this is a common fault on the Xbox One, more common than Microsoft will probably admit.

In this article, we will help you fix the issue – worst case, there are some tools you will need and we will need to replace a chip (IC) on the motherboard, but this issue can sometimes be fixed by a few quick and simple steps.

So how do I fix it?

First of all, let’s try some diagnostics tests:

Diagnostic Steps..

  • Check that your TV is set to the correct input signal (HDMI).
  • Ensure that the HDMI cable connection to your console is secure.
  • Check that the HDMI cable connection to your TV is secure.
  • Check that the HDMI cable is connected to the “out to TV” port on the console.
  • Perform a cold boot on your Xbox One console by holding the power button on the front of the console for 10 seconds, and then turn it on again.

Is your Xbox faulty?  Need your HDMI port or retimer replacing? booBeam have teamed up with Console Therapy who provide a full range of professional, cost effective and express game console repairs.  Console Therapy will charge as little as £49 (€55) to replace your faulty retimer chip and HDMI port  

Still Not Working?

Still not working?  Ok, lets try resetting your display settings:

  • Eject and Disc's which are inside the Xbox.
  • Press and hold the Xbox button on the console for five seconds to turn off the console.
  • 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.
  • Your Xbox One should then boot into low resolution mode (640 × 480).
  • Check your video settings are compatible with your TV and restart your Xbox One.

What Else Can We Try?

  • Connect the HDMI cable into a different HDMI port on your TV.
  • Use a different HDMI cable to connect your console to your TV.
  • Connect your console to a different TV.

Still No Luck?

We are sorry to hear that, it could be the HDMI Retimer chip (IC) on the motherboard is faulty, or the HDMI port itself is at fault.  To dig a little deeper on either of those, we need to open up your XBOX One.  Now, a point to remember, if you open your Xbox One you will invalidate your warranty, so only follow these next steps if you are no longer covered under warranty.

Our video above shows a full guide on how to open the Xbox ONE S and give a full overview of diagnosing and fixing the issue.  These are the steps we share in the video:

Open the Xbox
Firstly, turn your Xbox One over and pry off the black cover on the underside of the console. Now, undo all the screws (these are Torx type)

Flip the Xbox One back over, being careful that the Hard Drive and Blue Ray drive do not fall out, and start to remove the Hard Drive, Blue Ray and Power Supply by disconnecting their cables from the motherboard.

Remove Wifi & Power board
Next remove the Power Button and Wifi controllers from the side of the Xbox One by simply unscrewing and pulling off.

Don’t Forget
Remove the small metal clip which is above the USB port.

Remove the Motherboard
Take a hold of the heatsink and fan and lift out the motherboard. Turn the motherboard over and remove the X shaped clamp which is holding the heatsink to the motherboard

There we have it, one bare Xbox ONE Motherboard.

Our Recommended Tools

To make this next part of the process easier, we recommend purchasing decent tools to make the job easier.  Below are a selection of tools we recommend 


Take your multimeter and check the HDMI fliters – please watch the video on the best way to do this.  If the HDMI filters are all good, then I am afraid it is a HDMI Retimer replacement that is needed.
