I have purchased 2 royal sovereign fs-2d's used from amazon, one after another was returned. Both of them arrived in non-working condition. After the second attempt to replace the item a customer service rep asked me if i would rather have a refund and just keep the item. So i chose to do that, and kept the second non-working coin sorter, which appears to be in great physical condition, it just wont sort coins. It comes on, screen works, buttons work, except for the start/stop button. I went on google for a while and looked but all i can find is the manual for the item. I dont want to read the manual, i want to find a forum where someone has had this issue and fixed it and i cannot seem to locate one. Which seems odd. Can anyone help me with this? Either with repairing the device or pointing me where i need to be looking? maybe someone else knows what i need? Thanks
