Panasonic PT-DZ770E Operating Guide

■ To get a good picture quality

In order to view a beautiful image in higher contrast, prepare an appropriate environment. Draw curtains or 

blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor lamps 

from shining onto the screen.

■ Do not touch the surface of the projection lens with your bare hands.

If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and 

projected onto the screen. Please put the lens cover (accessory) on the projector when you do not use it.

■ DLP chips

▶

z

The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or 

always lit. Note that such phenomena does not indicate malfunction.

▶

z

Directing a high-power laser beam onto the lens surface can damage the DLP chips.

■ Do not move the projector while it is operating or subject it to vibration or 

Doing so may shorten the service life of its internal components.

■ Lamp

The luminous source of the projector is a high-pressure mercury lamp.

A high-pressure mercury lamp has the following characteristics.

▶

z

The luminance of the lamp will decrease by duration of usage.

▶

z

The lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or 

degradation due to cumulative operating time.

▶

z

The lamp life varies greatly depending on individual differences and usage conditions. In particular, 

frequently switching the power on/off accelerates lamp deterioration and greatly affects lamp life.

▶

z

Continuous use for over 1 week will deteriorate the lamp. The degradation of the lamp due to continuous 

usage can be reduced by lamp relay function. (

The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace 

the lamp unit regularly.
