Looking at the circuit board pictured on the LCL website (why do they show the old model, not the latest one they are crowing about?) it looks as though there is no rocker or toggle switch to focus. There must be a relay off the main board, which is not working, controlled by the IC, that operates the relay. But there are four terminals marked Lin/Lout and Nin/Nout, plus a low-current glass fuse. Confusing...
