NVR Cannot bootup

We are your reseller in Singapore. We have a brand new 4Ch NVR that cannot boot-up and seems dead machine that without any response.
We have other 4ch/8ch NVR in stock also but don't have the bootup issue when we used the same monitor and same 48V power adaptor to test them.

Can we know how u can replace us the parts or motherboard for this new NVR that we have received only a month?

We opened the faulty NVR and see that the motherboard has red led near the on/off button switch, can u tell what is the issue?
