Hi, 

Thank you for providing the pictures of the contacts and for clarifying that the display is completely dead. 

I have shared the pictures with the technical team and they could not see any water damage on the contacts which is really good news! They have said that the display normally "dies" because of the fuse on the 3 pin socket side. You can replace the fuse yourself as this would not interfere on how the cable works and it is something that can happen with any appliance, can you please advise if you'd be able to try changing the fuse and see if it works, if it doesn't work after a fuse change we will have to RMA the cable for further testing. 

I hope this makes sense, but if you have any queries or would like to discuss further please let me know and I am happy to assist or clarify!

Thank you,
