I have a NUC6i3SYH with hyperX impact 16GB DDR4 and samsung 850 EVO 250 GB M.2 SSD.
Everything was working fine for 2 years when one day the NUC stopped sending signal to the monitor.
I've tested the monitor with other laptops and I've tested the NUC with other monitors to make sure it is not a cable/monitor issue.
I've also tried the display port and that didn't work also.
I've tried powering on with just 1 memory or without any and that didn't worked.
The NUC power button works fine and the blue light is on (not flashing or anything).
1. Without any SODIMM installed, the front LED should blink. Does it blinking?
2. You may try to recover bios using Security Jumper Removed method. This method doesn't require any user input.
3. If the recovery will not help, probably it is some hardware problem and you may ask for RMA for replacing your NUC. Since your NUC is only 2 years old it is covered by warranty: https://supporttickets.intel.com/warrantyinfo?lang=en-US Warranty Information
Thank you for your reply.
To answer your question, yes, the LED blinks in a pattern of 3 without SODIMM installed.
I've did the steps you mentioned and nothing changed. Still no video output.
Any other ideas?
Your bios is recovered to the last version. So, I assume that not Bios code destruction is causing this problem. Blinking LED with SODIMM removed indicates that the POST is executed (the three blink code, indicates memory failure and this is correct indication since no RAM memory is installed). The failure may be caused as result of SODIMM failure. Now, the next step I suggest is to verify if the RAM you have is not failed.
1. If you have one SODIMM module only, please move it to the second memory slot.
2. If still the NUC is not working, try other SODIMM (may be you can used one from laptop or, borrow one).
3. If you have two memory modules, install only one at time, first in lower slot and then in the upper slot.
