OP-Z Oplab issue. No lights on back

Having issues using OP-Z with Oplab & a PO 400. Yesterday I was good. I had the Oplab set to PO and I was able to see the indicator lights on the back when playing keys as per the Manuel. I made a patch and things were good. Now today. I don’t see any lights on the back and the same patch creates no sound. I checked the config on the module channel of the OP-Z but I don’t see anything wrong. Anybody experienced this ?

Maybe the module has physically lost contact with the OP-Z’s mainboard? I would check if the module sits correctly in place. Also, shortly after switching on the OP-Z, the module’s LEDs should fire up in a sequence indicating that it is properly connected. Good luck!
