This is my second NUC6CAYH with the same problem: no video signal. Maybe is it because of the ram Kingston KVR16LS11/4 ??
But the blu led is not blinking for memory problems (3 blink)
I try clearing CMOS but still got no video with both hdmi and vga. I try on two different monitor: LG 24MP88HV-S (hdmi &vga) and Hanns-G HW191G (vga).
The first nuc was a reconditioned product, so I think it was faulty, but now I suspect that the ram is faulty. Could it be also with no blinking message ???
I try to boot also with no SSD drive installed. Nothing. For info it is a Drevo X1Pro.
What do you suggest me to do ??? I could try to connect to other monitor at work but at this point I don't know if it makes a sense.
The LED will flash if the NUC is unable to initialize the memory. The fact that it doesn't flash doesn't mean that there isn't any problems with the memory, however. If this is the second NUC that you are having problems with, the memory very well could be the problem. Unfortunately, the only way to know may be to test with different memory. There is one thing that you can try with what you have now, however. With only one DIMM installed and VGA monitor directly connected, turn on the unit and let it sit for 30 minutes. If there is a problem with the memory and the system is hanging as a result, the watchdog timer should eventually wake the system and a message be produced on the screen.
Hope this helps,
The slot shouldn't matter - but, by all means, try moving it to the other slot and see if this makes a difference. If this doesn't work, you can try a different DIMM. Try to find a shop that will let you test it before purchasing. As to what to try, all I can say is I am not a fan of Kingston and I usually purchase Crucial. This is the DIMM I have in my NUC6CAYS: CT102464BF160B.M16FN.
Hope this helps,
