6-2 Before Replacing The LCD/Lens Prism
You should not replace separately the parts of the liquid crystal LCD/Lens prism because it works properly
only when used together. Therefore, regarding these parts, you can either replace part, LCD/Lens prism
assembly, or send the whole unit LCD/Lens prism assembly back to HITACHI, where we will replace the
malfunctioning part, recondition the device and send it back to you.
Reset the PANEL TIME whenever you change the LCD/LENS prism assembly. With reference to the
PANEL TIME, see the section “6-13 HIDDEN SERVICE MENU” in this manual.
