    Good evening.

    I have a BH pioneer pro treadmill with a Endex DCMD67M board with problems. I think there is a short circuit. It has been changed grinder and a few more pieces transistor) . The engine has been seen and is working well . The last time I called no weight worked for more than 10 minutes without problem. So I put myself in it stops working , burning a fuse. For this description someone help me? You think you can compose the board ? Or is better to buy a new one?

    Check/Test the power Mosfets and the bridge rectifier.
    Also the small circular controll circuit bridge rectifier.

    What does the 'E1' error signify?

    To the left of the motor +- terminals, that 8 pin ic looks like it has some issues, or perhaps it's just the way the light is hitting it.
