三菱显示OSD锁上嘞，求解锁方法。急！！！

OSD
main osd menu

this menu is not displayed when the signal is not input.

press the "menu" key and the main osd menu structure will display as shown on the right (fig. 19). whenever av box is attached, 4 sub-pages will display in the menu: display page, image page, control page, and source page. however, if the input is from a pc and no av box is attached, source page will not display in the menu.

press the "menu" key again to enter display page items, or press "" (keystone-) or "" (keystone+) to select the sub-pages. (the main osd menu will automatically disappear if no key is pressed within 10 seconds).

press the "exit" (auto) button to leave the current sub-page, and press "exit" (auto) the button again to leave the main osd menu (at the same time the settings are saved).
