- Disconnect HDD and boot NVR. If NVR boots without HDD, then HDD has failed or is not compatible.
There are following possibilities:
- Input voltage is not stable or it is too low.
- HDD malfunction or something wrong wit the ribbon.
- Button power is not enough.
- Front video signal is not stable.
- Working environment is too harsh, too much dust.
- Hardware malfunction.
