I have been using Intel NUC for 4 years without issues until yesterday. When I tried to start the device, the power led started keep flashing 16 (?) times and it does not respond.
When I googled the issue, I found the corresponding reason : Thermal trip warning. As a matter of fact I did not do anything unusual. What do you think I should do to make it work back again ?
I do use it for listening music (Roon OS is installed only).

1. Could be that the cooling blower is clothed with dust. When you depress the power button, can you hear that the blower is spinning?
2. In case that you suspect that the cooling solution need to be cleaned , please see this tutorial how to do this. The last steps (replacing the thermal paste) is not necessary to do. This tutorial is for NUC BE, but is should be very similar to your NUC.
3. An additional thing that I advice to do (take the opportunity that the board is removed), is to disconnect the CMOS battery connector and reconnect it after 15 minutes. This will reset the BIOS. You should check if the CMOS battery is not discharged and in case that its voltage is bellow 3VDC, replace the battery.
