¥ There is a relationship between the adjustment of items R-GAIN, G-GAIN,
and B-GAIN and that of item CONTRAST. For example, when adjustment
values are : R-GAIN: 0, G-GAIN: 5, B-GAIN: 0, and CONTRAST: 0, changing
CONTRAST to 1 changes the adjustment values as follows: R-GAIN: 1, G-
GAIN: 6, and B-GAIN: 1.
Also, when the adjustment value of any of R-GAIN, G-GAIN, and B-GAIN
has reached -30 (minimum) or +30 (maximum), CONTRAST cannot be
adjusted to any higher value. For example, when R-GAIN is 0, G-GAIN is 5,
B-GAIN is 0, and CONTRAST is 0, increasing CONTRAST allows the other
adjustment values to increase until R-GAIN: 25, G-GAIN: 30, and B-GAIN:
25, then CONTRAST becomes 25 and cannot be adjusted to any higher
value.

48 Replacing the Light-Source Lamp 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 lampÕs used hours exceed 900 hours, the projectorÕs LAMP indicator comes on. Also, at the start of projection (lamp energized), the message ÒREPL.-LAMPÓ appears on the projection screen for about two minutes. Then, replace with a new light-source lamp, or arrange for a replacement lamp. When lampÕs service has reached 1000 hours, the projector Õs LAMP indicator starts blinking, and if you press the OPERATE button (or press the remote controlÕs OPERATE button for more than one second), the light-source lamp does not turn on. 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. Purchase new light-source lamps (part No. : BHL5001-SU) from the authorized dealer where you have purchased the projector, or consult the Service center. CAUTIONS and NOTES ¥ If the projector is set up in a tight place which is unsuitable for work, and if you perform replacement work there, this could hurt you. Move the projector to a place wide enough for work, and then replace the lamp. ¥ Use a genuine product for the light-source lamp. If you use other than a genuine product, this could cause a malfunction. Also, never use an old light-source lamp. An old lamp could cause marked degradation in performance or explode itself, possibly causing the projector to malfunction. Also, its broken pieces could come out of the projector and harm you when replacing the light-source lamp. ¥ Do not replace the light-source lamp immediately after the projector has been used. The temperature of the light-source lamp is still high and could cause a burn. Be sure to allow a cooling period of one hour or more before performing replacement work. ¥ Before starting lamp replacement work, turn off the MAIN POWER switch (see page 26), and disconnect the power cord from the wall outlet. If you perform the replacement work with the power cord left connected, this could cause harm or electric shock. ¥ Never discard an old light-source lamp (used lamp), as is. Otherwise, this could involve a great danger. The lamp contains a xenon gas inside, which is applying a high pressure. If the gas is not removed, it could cause the lamp to explode. For handling used lamps, refer to the manual supplied with the new replacement lamp you have purchased. If you have any questions, consult a authorized dealer where you have bought the replacement lamp or Service center. Screw Lamp-replacement opening cover Be careful not to damage the claw. 1Remove the lamp-replacement opening cover by loosening screws. Loosen the two screws with a flat-end screwdriver.
