Panasonic PTLZ370E Operating Guide

■ In order to get the picture quality

▶

z

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, in order to obtain high-quality images with higher contrast.

▶

z

Depending on the conditions of use, the screen may fluctuate due to the hot air from the air exhaust port or 

the heated or cooled air from the air conditioner.

Take care so that the exhaust from the projector or other equipment, or the air from the air conditioner does 

not blow toward the front of the projector.

▶

z

The projection lens is thermally affected by the light from the light source, making the focus unstable in the 

period just after switching on. Focus stabilizes 30 minutes after video projection starts.

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

If the surface of the 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.

■ LCD panel

The LCD panel is precision-made. Note that in rare cases, pixels of high precision could be missing or always 

lit. This is not a malfunction.

Also, projecting a still image for extended periods of time may lead to afterimages on LCD panels. Please be 

aware that in some cases these afterimages may not disappear completely.

■ Optical components

If using in an environment with a high temperature, or where dust or tobacco smoke is present, the 

replacement cycle of optical components such as LCD panels and polarizing plates may shorten even after 

less than one year of use. For more details, please consult your dealer.

■ Lamp

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

A high pressure mercury lamp has following characteristics.

▶

z

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

▶

z

The lamp may burst with sound or shorten life by shock or chipping.

▶

z

The life of the lamp varies greatly depending on individual specificities and usage conditions. In particular, 

continuous use over 12 hours and frequent on/off switching of the power greatly deteriorate the lamp and 

affect the lamp life.

▶

z

In rare cases, the lamp burst shortly after the projection.

▶

z

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

the lamp unit consistently.
