In GY-HD110 special menu, Camera1 submenu, there is no LCD L/R reverse and FAS Audio option, just ALC mode, EEI max, IRIS ENF and Pixel compensation options.

I entered even in other two service modes with Camera2 and Camera 3 and VTR1,2,3 submenus and there is no LCD L/R reverse option.

I think this is because the GY-HD110 has in the main menu LCD mirror function.
