Power To HDD Causes Display To Fail - Dahua NVR4104HS

[Dahua_Queries]

Hello all,

First time poster, long time reader.

I have the above model number Dahua NVR system.

It works perfectly fine, except recently when trying to install a HDD.

As soon as i try to connect the SATA 15 pin to 4 pin plug into the motherboard the display to the TV is lost.

Once removed the display continues as normal.

I have tried a number of 4 pin plugs but the issue persists.

I have attached images showing the current setup.

Any help would be much appreciated.

Thanks.
