TVS 672XT not power on

[r.kumacse]

Hai
I bought a tvs 672xt 3 years before(warranty is finished 6 months before). It was working properly. suddenly its went to power off .But the ethernet link is blinking in amber. Its not power on. I tried different power cable, power socket and removed all hdd. Even though its not power on. But i can see a tiny red led is on in the motherboard which is only visible if we open the panel. What could be the issue power supply or motherboard?
Thanks in advance.
