I suggest that the first thing you should do is to update to the latest available BIOS using the Recovery Method. You can download the latest available BIOS release here: Download BIOS Update [PYBSWCEL.86A]. The process for updating the BIOS using the Recovery Method is documented here: BIOS Recovery Update Instructions for Intel® NUC.
Hope this helps,
Thanks for your reply.
Apologies, I should have mentioned
1. Everything else is working fine. I can see the boot screen with Intel NUC logo, I can boot into windows
2. I flashed to the latest BIOS using the windows tool.
The only thing I can't do is see the BIOS screen after I press F2.
No, you need to reinstall the latest BIOS using the Recovery Method. Using the Recovery Method ensures that every firmware component is updated (refreshed), even if they (supposedly) haven't changed. Once you have done this, attempt to enter BIOS Setup again. If you cannot, power off and then power on again, but this time hold the power button down for ~3 seconds. This should cause the recovery menu to appear (it may take a few seconds to do so). Pressing F2 from this menu should take you into BIOS Setup. If it doesn't, let us know...
Unfortunately that didn't work.
1. I downloaded the BIN file, flashed the latest BIOS using recovery mode
2. I downloaded the oldest BIN file, flashed the BIOS, no display.
I think my TV just doesn't support the resolution if the BIOS. I will take the NUC with me to work today and try it with my office monitor.
I brought my NUC with me to work, today, weird behaviour
1. Connected it to my office monitor via HDMI - BIOS screen black
2. Connected it to my office monitor via VGA - BIOS screen black
3. Tried flashing the same BIOS again using recovery mode - Failed. After F7--->Selecting the media--->Selecting the .bio file, it reboots and boots straight into windows
4. Reset CMOS using the motherboard jumpers, rebooted, can see BIOS screen now
5. Made some changes, clicked Save and exit - failed, discard and exit- failed. Whatever I do, it just won't save the changes or exit, it just goes to the search bar on the top
6. Tried F7 recovery flashing again, worked. Cleared CMOS again, just to be thorough
7. Can save settings etc, exit the BIOS.
8. After a few reboots, again a black BIOS screen
Either something is wrong with my hardware, or there's a bug in the BIOS. Since I have changed the settings to my liking now, it's OK that I cannot access the BIOS at the moment, but would like to know if there's a formal way to file this as a bug with Intel.
Meanwhile, will keep an eye out for BIOS updates.
After much troubleshooting, I have found out the issue. The BIOS screen will remain black if I boot the NUC with the SDXC card in place. Without the SDXC card, everything is fine.
Thanks everyone for their help.
slyronit, can I ask what SD card you're using? Brand, capacity, technology? I just tested 3 different SD cards; 64GB Transcend, 128GB sandisk full to mini adapter card, and a 256GB Kingston, all U3 and XC I, on a NUC5CYH, which is the exact same BIOS, and found no issues. I'll try them on a NUC5PPYH tomorrow.
It's a 128Gb Sandisk micro SD using an adapter. I just tried this again and got the same results. With the card in, black screen after F2, without the card everything is fine. I wouldn't be surprised if it's the SD card at fault. I have had many issues with it lately, it wouldnt even format to NTFS on any system, only Exfat.
Thanks for the speedy reply. Let me try it on a PPY and I'll let you know. Do you have any other cards that you can test, or if you have, do they work?

Thanks for the information. Please see the list of tested peripherals, I see the following SDXC cards compatible for your NUC.
SanDisk Extreme SDXC UHS-I U3 64 GB SDSDXN-064G-G46 SanDisk Extreme SDHC UHS-I U3 32 GB SDSDXN-032G-G46
Tested Peripherals for Intel® NUC Kits NUC5CPYH/NUC5PPYH
Thanks all, I tested with an 8Gb Sandisk card (the only other card I have) and didn't face the same problem. I think it is safe to say the problem is with my 128Gb card.
Very strange. That's almost exactly the same card I have and it works fine. Bugger.
