Hi guys. Does anybody have any tip for solving Axperts inverters failures 05 (short circuit) and/or 07 (overload)? I have an inverter and a motherboard in fault 05, and an additional inverter in fault 07, and of course I would like to fix them. I have checked all of the IGBTs, mosfets, transistors, diodes ....(and even all of the resistors of them), and couldn't be able to find any component in failure. I appreciate any suggestion
