Treadmill controller (zipro dream (?)) - PCB-ZYXK9- 1111-V1.2.PCB not working
Hello
I received a treadmill controller (probably Zipro Dream) for repair (more like replacing parts). Board designation: PCB-ZYXK9-1111-V1.2.PCB. existing in it were:- mosfet Q9 (originally MDF4N60 was installed) - mounted on P10NK60ZFP;
- resistor R64 (replaced);
- F2 protection.
After turning on the power of AC1 and AC2, the components burned again. The existing elements were desoldered and new ones were soldered. The controller has not been connected yet because I'm afraid they would be destroyed again.
There are no additional restrictions that can be applied,... -
