10.3 Backlight Replacement
10.3.1
FP-3710K Series
FP units use a CFL, long-life type backlight. The actual life of the backlight however, will vary depending on
the FP’s operating conditions. It is recommended that it be replaced periodically. The service life (half
brightness life) of the backlight when it is lit continuously at room temperature is as described below.
50,000 hours --- approx. 5.7 years (ambient temperature: 25°C, when lit continuously)
Preparation
Please have the following ready beforehand.
•
Replacement backlight (Model:CA7-BLU15-01 (Set of two lights))
•
One pair of clean (preferably new) cotton gloves.
•
Phillips screwdriver (no.2)
•
If the backlight or the display unit is damaged, the screen display will go out. Even if the
screen goes out, however, there is a possibility that the touch panel is still operating cor-
rectly. Therefore, since any type of touch panel contact could have an unexpected or dan-
gerous effect or result, be sure not to touch the screen when this condition occurs.
•
A backlight burnout is detected by monitoring the consumed current. Depending on the
condition of the backlight, a backlight burnout may not be detected or it may be detected
before the backlight burns out completely.
[Electric shock]
• Whenever changing the backlight, be sure the FP’s power cord has been disconnected
and that the unit is cooled down.
• When the FP’s power cord is connected and the FP is ON, high voltage runs through the
wires in the backlight area, do not touch them!
[Burn]
• When the FP’s power has just been turned OFF, the backlight area is still very hot! Be
sure to wear gloves to prevent being burned.
[Glass]
• The backlight is very fragile. Do not touch the glass tube directly or try to remove its
power cord, if the glass tube breaks you may be injured.
