Before Replacing the LCD / Lens Prism
You should not replace separately the parts of the liquid crystal LCD / Lens Prism because they only work properly
when used together. Therefore, regarding these parts, you can either replace the LCD / Lens Prism assembly or send
the whole LCD / Lens Prism assembly back to Hitachi, where we will replace the malfunctioning part, recondition
the device and send it back to you. Please contact our distributor.
