The USDM clocks have dual circuit-boards and EURO/JSPEC clocks only have a single one. (Not sure why they didn't use a single design worldwide, since it's just a clock) Also there's a difference between the USDM main (display) circuitboard and the JSPEC/EURO board. As far as I can tell a common issue with the USDM clocks is that these go dim first, as where the JSPEC/EURO clocks stop working completely. I have already taken a USDM clock apart and think I may have found a similar issue with these as well (continuity failure between upper and lower layer of the circuitboard) As soon as I have found a fix for these boards, I'll post it here also.
