I think Sean, found of slimdevices, has not posted since 2010,s o it's unlikely that you hear anything back. If you are in the EU, try to contact Jo (https://forums.slimdevices.com/member.php?23131-JoeMuc2009). If you are in NAM and you think you've just fried the motherboard, I have a spare one and we can try the CPU board. If this is the one fried, then the SB3 is garbage, unfortunately LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
