More fun and games with the Thomson...
Came home to find a green light, a/v working fine but no response from the remote control save the flashing red r/c light in response to a button push.
Power cycled but the unit firmly stuck on the yellow light of doom
After removing the new HDD from the Silent Box, removing the new connecting cables and plugging it stright into the PVR using the existing power and data cables I finally got a working unit.
The question is, what caused it and can I recover from it?
Opening up the Silent Box I found the HDD to be very warm indeed and the gel plate not so warm - had I put it on properly?
