Replacing the Lamp (For service personnel only)
Lamp and Lamp Usage Time
The maximum life of the lamp used for this unit is about 2000 hours, and may be far less depending on the type of usage and projector
settings.
• The lamp life may not reach 2000 hours depending on the operating conditions.
When the lamp approaches the end of its service life, deterioration progresses rapidly. Get ready or replace with a new lamp when the ac-
cumulated lamp usage time exceeds 1900 hours. Depending on the operating conditions, the lamp may have to be exchanged earlier. If
the image is dark or color tone abnormal, replace the lamp as soon as possible. You can also check the accumulated hours of usage. Please
refer to the “Lamp Hour” item of the “Information” menu. (Page 23,)
Please consult your authorized Vidikron dealer when purchasing a new lamp unit
■ When the lamp usage time exceeds 1000 hours
A message indicating “1000 h” will be displayed on the screen.
• Press the [EXIT] button to clear the display.
■ When the lamp usage time exceeds 1900 hours
The [LAMP] indicator lights up.
■ When starting projection after lamp usage time exceeds
1900 hours
The “Lamp replacement” message will be displayed on the
screen.
• Press the [EXIT] button to clear the display.
■ When lamp usage time exceeds 2000 hours
The [LAMP] indicator starts to blink.
The “Warning” and “Lamp replacement” messages will be displayed
on the projected screen with the “Warning” word blinking.
• Press the [EXIT] button to clear the display.
However, the same “Warning” and “Lamp replacement” messages
will be displayed again after 1 hour.
When the unit is switched to the standby mode or turned off after
the lamp usage time exceeds 2000 hours, it cannot be switched
back to the projection mode again. In this case, replace with a
new lamp and reset the lamp time.
■ When the lamp usage time exceeds 2010 hours
The unit quits the projection mode (operating mode) and switch-
es into the cool down mode.
• The [LAMP] and [OPERATE] indicators will start blinking.
• The projection mode (operating mode) cannot be restored until
a new lamp is replaced and the lamp time reset.
• If this unit is installed in a constricted place, attempting to replace the lamp in that place may cause injury. Move this unit to a place
large enough to perform the work.
• Use only genuine replacement parts for the lamp unit. Otherwise, malfunction may occur. Also, never attempt to re-use an old lamp
unit. This may cause marked performance deterioration or lamp blowout, thus leading to unit malfunction. Broken pieces of the lamp
outside this unit may also cause injuries during lamp unit exchange.
• Do not replace the lamp immediately after this unit has been used. The temperature of the lamp unit is still high and this may cause a
burn. Allow a cooling period of 1 hour or more before replacement.
• Before replacing the lamp unit, pull out the power plug from the outlet while the [STAND BY] indicator is still on. Replacing a lamp with
the plug connected to the outlet may cause injuries or electric shocks.
About Lamp Replacement
Resetting Lamp Time
After your Vidikron dealer installs a new lamp, he will reset the lamp time. The lamp time counter will be reset and a new count will start.
If display of the accumulated lamp time has reached 2000 hours, this unit will not work (lamp does not light up) unless the lamp time is
reset.
