I bought my EF3000iSEB in 2009 or 2010. The Control Unit is bad. How do I determine the correct part number? I see 7CH-8A210-A0-00 and 7CH-8A210-D0-00 listed in various places, some indicate "all years". I suspect that these replaced the earlier parts 9999etc.., but can either one work on my machine?
Thanks Bill. I still need the control unit. I need to find my notes, but my research turned up some very confusing results. I finally spent some quality time with a very helpful Yamaha USA rep and am pretty sure which unit I need: P/N: 7WL-8A210-56-00.
The only number I could find on the original part was: 08030810
Please let me know what info you can from your part. I live overseas, so between the shipping and outrageous duty & tax, I cannot afford to make a mistake. Regards, Neil
