In regard to your concern, I would like you to please confirm if you have the following BIOS version otherwise, proceed with the proper update(if you have an older version, you will need to complete a gradual update from your version till the latest one, without avoiding any version in between):
https://downloadcenter.intel.com/download/26338/BIOS-Update-KYSKLi70-86A-?product=89187 (version .0042 release date 9/29/2016)
As per your previous confirmation that you already have the latest BIOS version, you can skip this previous step.
Also, please confirm that you have installed previously all the following drivers if not please proceed to install them:
Intel® Management Engine Consumer Driver for Intel® NUC
Intel® HD Graphics Driver for Windows 7*, 8.1*, and Windows® 10 for the Intel® NUC Kit NUC6i7KYK
If this installation does not solve your issue, I would like yo to please confirm if your system may require any Windows update, due to sometimes Windows requires to update some of their drivers.
Please try to check if you need to complete any of the previous steps and let me know how it goes.
As of this morning, I had the following firmware/drivers installed:
- All Windows updates for Windows 10 Pro x64
- BIOS version 0042 (release date 9/29/2016)
- Intel HD Graphics Driver 220.127.116.1134 (release date 10/31/2016)
I did not have the Intel Management Engine Consumer Driver installed. I planned to do that tonight. However, upon turning on the TV this evening, I saw that the NUC was unresponsive...again. I took a photograph as evidence:
I will shutdown the NUC and attempt to install the Management Engine Consumer Driver.
Thank you very much for your reply. All the details are really appreciated.
Please let me know if you are able to see any positive results after the driver installation.
If the issue persists I will continue the investigation based on every detail that I have received by far.
Please let me know how it goes.
I would like to know if you were able to see any positive results?
If your issue persists do not hesitate to reply back.
Sorry for the delay in replying. Since my last message, I've not only installed the Intel Management Engine Consumer Driver, but I replaced the HDMI cable (just to be certain) and reflashed the HDMI 2.0 firmware.
I'm happy to say that the NUC has been working flawlessly! I hope it continues to work this way.
Thanks for all your help, and Happy Holidays!
