I was able to replace the PTC with an exact new part ordered from Aliexpress, but it didn't fix my defect meter. So it must be the controller itself that got damaged accidentally. And replacing that is not worth it because these meters new are cheaper than those replacements cost. Anyway finding the right pin configuration for the 42 pin or alike smd controller used on these printed circuit boards is also difficult to be able to do just that. Why I keep my defect Digital meter now just for scrap parts.

Ok same problem here my PTC has burn and Q1 (S9014 SMD) too under the buzzer.
Will change both of it. hope it will be enough.
