    NUC DN2820FYKH will not display after BIOS update


      Prior to attempting to install Windows 8.1 (x64) on a new DN2820FYK NUC, and as per Intel's OS installation notes, I undertook a BIOS update via a flash drive containing the latest version available, FY0025.bio.  According to the screen display, the update appeared to go ok, but after restarting, there was no longer any display at all.


      I have tried the BIOS Recovery procedure (removing the jumper etc)  The power led does flash for a few minutes, as if it might be loading something, but then just goes steady-on until the unit is turned off. When re-started, the power light goes on but nothing is displayed, and pressing F2 etc does nothing.  I tried the CMOS clearing procedure also, and then BIOS recovery, but still no display.  I also reseated the 4gb 1.35v memory module just in case, even though it did not cause a problem when the NUC first booted up to the BIOS it shipped with.


      I have subsequently tried the NUC on 3 Panasonic TVs (all of which are XGA (1024x768) capable), a Samsung monitor (also 1024x768 capable), and an LG TV which may or may not be 1024x768 capable.  All connections have been by HDMI.  I have also tried 3 different HDMI cables, 2 of which at least are 1.4a, and are already used for carrying video and 5.1/7.1 audio from a Core i5 laptop, WD media player and 3D bluray player.  I have tried various combinations of cables and TVs, and repeating attempted boot-ups, BIOS recovery, etc.  No luck.  Apart the initial boot-up and BIOS display, the unit hasn't displayed a thing since the (uninterrupted!) BIOS update.


      All up, I have probably wasted about 8 hours so far, not to mention the hours reading forum posts from all over the place.  I realise now from the forums that these Haswell NUCs have more than their fair share of BIOS-related problems, but can anyone suggest any other procedures I can try to bring this thing back to life??

          Myles999, I am sorry to hear you are having problems with your new NUC, but I will be more than happy to assist you on this issue.


          I was reading your comment and it looks like you already performed all the recommended troubleshooting on this type of product. However I will like to know which BIOS version you are trying to install through a BIOS recovery?

            The latest BIOS I could find was FY0025.bio.  I downloaded it a couple of
            times onto different USB sticks after the initial failure, just in case there
            was a problem with the download or with one of the sticks.  No success. After repeating the
            recovery procedure a number of times on different display/cable combinations, I
            even tried recovering the previous version (0021) just in case that might at
            least display something and let me into the BIOS.  No luck on anything.


            I have now contacted Intel support center and have supplied some more info to them that they asked for.  All I can hope for now is that Intel will indicate that the unit appears to be faulty so that the retailer will agree to issue an RMA.

              Ok Myless9999, once you receive the replacement NUC, please stay on BIOS 0021 until we find a solution.
