We replace the voltage regulator in the ZKE-Tech EBC-A20. This will fix it, right? It does, but... Houston, we have another problem.
That would have been way to easy. The device turns on again and the display lids up, fine, it seems to work again. Well, not quite. There is another problem with the tester.

Is this fixable at all?
