About Light-Source Lamp Replacement

The light-source lamp has its service life. It is approximately 1000 hours.

When the light-source lamp approaches the end of its service life, its degradation progresses rapidly. When the lamp’s used hours exceed 900 hours, the projector’s LAMP indicator comes on. Also, at the start of projection (lamp energized), the message “REPL.-LAMP” appears on the projection screen for about two minutes. Then, the light-source lamp needs to be replaced. When lamp’s service has reached 1000 hours, the projector’s LAMP indicator starts blinking. The specified lamp replacement period is 1000 hours, but depending on use conditions, the replacement period may vary. If video image is dark and its color tint is extraordinary even after you have adjusted color tint and brightness, replace the light-source lamp a little earlier.

For replacing the light-source lamp, consult the dealer where you purchased your projector or a local service center.
