WD15 Short

Hi,

Just a simple question to see if anyone has had this issue, and if so, any recommended fixes.

I have a WD15 dock, which has worked well for the passed year during the pandemic. It was second hand, but there was no noticable issues with it, and it's never failed. 

A few weeks ago, I noticed it wasn't powered on, so I disconnected it all, left it for ten minutes, then reconnected it. The PSU light is illuminated when connected to the mains, but once I plug it into the dock, the light goes out and no power flows to the dock itself. This has happened with a replacement PSU too. 

I'm happy to tinker, if I know what may have broken in the dock, but I don't know where to start, has anyone seen this issue, or know of a fix or test for it, please?

Jukesie.
