Last ditch attempt - U61 error on Panasonic BWT720 after successful HDD replacement.
Hi.
I bought a Panasonic BWT720 in 2013 and have had faultless operation from it ever since. However last week the hard drive in it died (mechanical issue, ticking sound and no spin up sound lead me to believe the drive is properly dead).
Being a software engineer and thinking "how hard can it be", a bit of Googling lead me to this :
www.avforums.com
After following the instructions and successfully replacing the hard drive, whenever I now boot the machine I get an error message on the screen and the code U61 displaying on the Panasonic box. Cue it auto-repairs, restarts, and infinite loop where this is now all it does. This is better described here :

The replacement hard drive I used was a brand new WD Blue :

As discussed in other threads I've found on AVForums, if I leave the aerial out, OR, have the player on AV1 (where I have nothing connected) but with the aerial plugged in, I can use the player as normal. For example I can get at all menu options, none are greyed out, I can access the HDD, I can access the Blu-ray player etc. There is nothing on the HDD though so I don't know if it would play from it. As soon as the aerial is plugged back in however and you start to watch live TV, the error message returns, you're locked out of using the machine and it resets itself.
I've run a HDD check on the machine using the service modes, checking both the Blu-ray player and the HDD. I've reset the machine back to factory settings using the navigation menu. However the problem still persists.
I've pretty much written off hope of recovery of the recording functionality, so I think the unit will just have to be a glorified Blu-ray player spare from now on. However I wanted one last ditch attempt to see if anyone had made any progress with this issue, or if it's simply better understood now that the error is unrecoverable.
Thanks for your time.
