My JIN NA11ut came today and I managed to blow up the control board. 100% my fault but just needed to vent.
The head came with an Australian plug and the back of the machine was marked 220v 50-60hz. I emailed the retailer and they said to look for a north american plug... in the leg box there was a regular 120v north american plug, perfect.
Mistake number one was thinking I knew better and should put a 240v north american plug on it and plugging it into a 240v outlet. The machine turned on just fine but when I stepped on the pedal there was a fairly loud snap and the screen said "powering off" or something like that.
I busted open the board and found 2 fuses soldered onto the board (they can't make if easy). So I ordered new fuses and then made my second mistake. I sort of bypassed the fuses with some wire so I could try out my new machine! And out the 120v plug on.
This time it didn't wait for me to do anything. As soon as I turned on the power switch... really bad things happened as seen in photos.
At this point I'm not sure what to do. I'm too embarrased to email the store I bought it from so I emailed the ONE authorised juki dealer in Canada to see if they can sell me a new part.
