If this happens, display the all whitescreen in the Test pattern for an hour or more.rOptical componentsOperating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke will reduce theservice life of the optical components, such as the LCD panel and polarizing plate, and may necessitate their replacementwithin less than one year of use. For details, consult your dealer.rLampThe luminous source of the projector is a mercury lamp with high internal pressure.A high pressure mercury lamp has following characteristics.f The brightness of the lamp will decrease by duration of usage.f The lamp may burst with sound or shorten life by shock or chipping.f The life of the lamp varies greatly depending on individual specificities and usage conditions. In particular, continuous useover 6 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.f In rare cases, the lamp burst shortly after the projection.f The risk of bursting increases when the lamp is used beyond its replacement cycle.
