Yes, continuity checked for all voltage supply lines to switches.

Fault is definitely pre-diode on the main digital board. All 4 diodes should have +5 at their chip-facing side, three of them have near zero, only one has +5, that is the one that supplies the aforementioned working switches.

Thanks!
