i agree. advice and suggestions can be freely given, but hands on work is just that. work. that involves using ones time, which is a saleable commodity, as well as ones knowledge and personal skills, which is also a saleable commodity. on the synchronars there is no source of new parts except the qc. repairing them is a crapshoot with the odds not in your favor. after having spent hours cleaning, tweeking, resoldering, etc., then to still have a dead module can be very discouraging. the only consolation in that case is you have enjoyed wasting your time.
even with payment for your efforts, you may still end up with a dead module. and an unhappy customer as well. i have spent my entire working life bringing antique timepieces back to life, and have thoroughly enjoyed it, but some things are best not even attempted. as someone on another forum says "i used to collect watches but it became too time consuming".
