I used the DP of the display. I tried the HDMI to HDMI connection, too. W.o. success.
I tried my spare display (I used bevore the 4k model) with HDMI to DVI, again w.o. success.
So no screen on any the ports.
What makes me wonder that it worked for month before. And it didn't fail during operation but simply at the next day.
I didn't make any BIOS update and there was no system (WIN10) update before it failed.
When I try to boot, the system LED indicates some operation, but goes out after a several seconds.
I didn't recognize any beeps from the diagnosis.
After that, it doesn't react on the start button untill I've removed the supply.
Does that indicate any RAM problems?
1. The blinking code for memory error is: 3 blinks (3 beeps), On-off (1.0 second each) three times, then 2.5-second pause (off).
The pattern repeats until the computer is powered off. So in your case it doesn't look that you have RAM problem.
2. Any way I understand that you even don't see the bios video (i.e. INTEL logo and F2,F7,F10 menu). In this case I'll try first recover bios, using bios recovery method with security jumper removed:BIOS Recovery Update Instructions for Intel® NUC . The last bios 0059 .bio file you can download from here: Download BIOS Update [SYSKLi35.86A] . I'm suggesting the security jumper method, because it starts and ends automatically. You don't need to see any video. If you don't see the update progress on screen, you shall see at least that the blinking led:
Continual blinks Off when the update starts, then on for 0.5 seconds, then off for 0.5 seconds.
The pattern repeats until the BIOS update is complete. After the update process finishes, switch the NUC OFF and then ON.
3. It can be problem also with your power supply. Can you try feed your NUC from an other power supply?
4. Try to power on your nuc with minimum components: 1 memory stick, without SSD, without HD.
