The sync button/switch came loose from the circuit board on my son’s 1708. I have the controller apart and the switch handy but it’s not obvious if/what contacts to solder. It looks like there are four pads in roughly a | | configuration. Would I solder all 4 ? I’ve also read to just forget it and use USB to sync.
well its a slandered switch so im guessing solder all 4 like with the other two switches rb and lb im more looking for the best method to do this as sync button is so %#*@ small
