Thanks - that’s interesting. Although I’m getting nothing.

Could be a dicky Powerlink cable, I’ll do a continuity test on it tomorrow.

Appreciate the help.

Sounds like a good idea.

I will try and see if I can get mine working in the weekend.

Good luck - interestingly, I found a green micro switch tucked away on the ICE board. Tried pressing it with power off and with power on, but no change. Could be that it needs to be held in for a few seconds ?

Just surmising of course, but there must be a reason for it.

I don't think it should be necessary to press a button. The button might be needed for service.

I soldered the new IC, but when installing the boards, I managed to rip off a bi-amp IC, so I am now waiting for a replacement for that. When installing the boards, they have to be forced down on each side of this plastic extrusion (pic 1). This means that the components on pic 2 are prone to being ripped off. Bad design...

Wonder if that’s the same on the 14 ? Must admit, I didn’t seem to have any mounting issues.

How far apart are the 14 and S8 in terms of design, componentry etc ?

My S8 is the earlier model, which should be identical to the 14's. Do you have pictures of the mounting on yours? I believe they use the same ICEpower module and power supply.
