Sony DVP-CX777ES auto adjustment issue
On my DVP-CX777ES, I ran the auto adjustment from the service menu because it was no longer playing any discs even after replacing the laser pickup. Put in DVD-SL, CD and DVD-DL in the first 3 slots. It does not run to completion unfortunately, at the bottom right of the screen it reports EMG.3A. I have the service manual but this code is not explained there. Does anyone know what the issue could be?
