Thank you so much.
I need this manual for understanding why my customer dvd player that bring to me for repair is only open and close repeatedly?
I service the open/close switch that connect to decoder Board and its ok but why Marshall Co. changes sequence of wire on-board(5-pin for open-close-G-M+ and M-) and tray status detection boards.?
why when tray is open the op and cl switch is connected to eachother and when tray is close off-course close pin and G pin is being connected to each other?
