Question Intel NUC boot issue

[skyking_comms]

I've purchased a D34010WYK i3 nuc which has a boot up issue.

The blue power light comes on for 8 seconds and then it powers off for 4 seconds. It then repeats that process over and over again.
Nothing appears on the screen.

I own 2 other NUC's so managed to swap some parts over that I know are working.

Here's what I've tried so far -

• Installed working DDR3L ram - tested in both slots
• Installed a working hard drive
• swapped over a working cmos battery
• Followed this guidance from Intel 'Unplug your Intel NUC from the AC outlet and wait for about 10 seconds. Press the power button on the front panel of your NUC a couple of times. When the Intel NUC is off, press and hold the power button for approximately 3 seconds, and then release'
• Swapped over the power supply to one I know works
• Followed these instructions for the security jumper. www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html Removed the yellow jumper, attached the USB with bios and now the blue power light stays on. It's been like it for 20 minutes rather than the 2 - 5 mins suggested. Doesn't look like it's attempting to read the usb stick and nothing comes on the screen

Any suggestions?

Thanks

It was no returns - do you think it's bricked?
