EX8000 No lights on the front

[stingray615]

Hi, I have 2 of these units, and one has stopped working.  There are no lights at all on the front of the unit, and on the back, next to the dc input, when it's first plugged in, it's green, then turns to yellow.  It's way beyond it's warranty, is it time to trash it?  I'm not feeling too confident about the Netgear brand right now.

Yellow? Not amber? usually its red or amber. 
if its amber, it might have corrupt firmware or something causing issues in the bootup process. 

You can try recovering it with tftp or nmrpflash.
are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.
