2 Hardware Replacement Methods
MITSUBISHI CNC
III - 8
2.1.2 Backlight
- 8.4-type
Driver: HN281
Backlight for replacement : 84LHS16
Backlight life : 70,000 hours (Duration of time until luminance drops to 50% of the initial value.)
The life is estimated on the assumption that it is used under 25
℃
environment. Keep in mind that the value above is not
a guaranteed value.
[Replacement procedures]
Always replace the backlight for LCD panel with the control unit (machine) power turned OFF.
(1) Check that the machine power is turned OFF. (If the power is not OFF, turn it OFF.)
(2) Disconnect the backlight connector from the backlight driver (one for top).
(3) Disconnect the MENU connector.
(4) Remove the escutcheon fixing screws (at 4 places) and take the escutcheon off.
(5) Remove the 4 fixing screws that are holding the LCD panel, and remove the LCD panel. Unplug the LCD cable
from the LCD panel at this time.
(6) Unplug the LED backlight cable.
(7) Pull out the backlight installed on the left side of the LCD panel. (The backlights have locking claws on the
front. Hold these claws down while pulling the backlight out.)
(8) Insert the new backlight into the upper and lower sections at the left end of the LCD panel. (Press in until the
locking claws click.)
(9) Connect the LED backlight cable to the new backlight.
(10) Connect the LCD cable to the LCD panel, and mount the LCD panel using the 4 fixing screws.
(11) Mount the escutcheon with 4 fixing screws (one each for 4 sections).
(12) Connect the backlight connector to the backlight driver.
(13) Confirm that all the cables are correctly connected and close the electric cabinet door.
(14) Connect the MENU connector.
[Precautions for using LCD panel]
(1) Response time, brightness and color may differ depending on the ambient temperature.
(2) Brightness nonuniformity, flickers and streaks may be observed on LCD display depending on the display
contents.
(3) Because cold cathode-tube is used for LCD display, optical characteristics (brightness nonuniformity and
display) change according to the operation time. (Especially in low temperature.)
(4) Screen display color may differ depending on the angle to view it.
CAUTION
1. Do not replace the backlight while the power is ON.
2. Dispose the spent backlight according to the local laws.
3. Do not touch the backlight while the power is ON. Failure to observe this could result in electric shocks due to
high voltage.
4. Do not touch the backlight while the LCD panel is in use. Failure to observe this could result in burns.
5. Do not apply impact or pressure on the LCD panel or backlight. Failure to observe this could result in breakage
as they are made of glass.
