Not sure off you can get it fixed locally. Maybe give Philips Tay a call.
You can try Japan camera hunter, Bellamy hunt.... He did manage to get it fix for his client. Probably more costly.
Also went through JCH to service mine. Minolta charges a service fee of 18,900Yen on top of whatever else that needs to be fixed. Costly but if you want peace of mind, its the way to go. Plus I heard they would cease service for the TC1 in the near future.
