I'm looking for one, too. My treadmill just died.
240vAC power to control board. Fuses okay.
Haven't gone further.
Supplier site (endex.com.tw) not helpful.
My PCB has "0407 Ji13 V2.1 DCMD67"
Serial#9403080002
If you learn anything, please contact: mrhox{at}yahoo.com with "DCMD67" in subject line.
Thank you! :)
