My mod board arrived from Lik-Sang today and I just couldn't wait to install it .....it didn't work!!! I checked everything..no joy :-( The motor wouldn't spin and all the startup (BIOS) sounds were slow and fragmented. SOLUTION: solder all the points as in mod documentation..then install mod board back to front (chips facing out of the unit). It's difficult to twist the ribbon cable, but it does go. All works fine now I apologise if this info is already here somewhere, but i felt i had to share this.
