I assume you tried powering it up without an SD card inserted and got the same result. Sounds like a bad power supply or a bad power connector on the board. Hard to tell. Do you have a meter to test output on power supply and input on the board.
If you had a power supply from an old IP webcam which has the same barrel connector you could try using it to rule out a DOA board. Those IP webcam power supplies are usually 2amp so it would at least boot up the Rock64 if it's working.
Alternatively you could just return the lot to the supplier
