DT168 won't power on, flickering power light

Hey all, first post on here!

Just yesterday, one of our DT168s stopped working, thankfully not during a service. Fuse is still good, I’ve tried a couple different IEC cables and power outlets (and tested it on our other dt168s and they all still work with them) so I’m a little stumped. All that it’s showing me is a green flashing light under “Power” on the box, flashes about 3 times per second.

Been looking around online for an answer but haven’t found anything yet! Any help is appreciated!
