6-4 Before replacing the LCD/Lens prism
You should not separately replace the parts of the liquid crystal LCD/Lens prism because they only work properly
when used together. Therefore, you can either replace the LCD/Lens prism assembly or send the whole
LCD/Lens prism assembly unit back to HITACHI where we will replace the malfunctioning part,
recondition the device and send it back to you.
