LAMP OPERATION TIME is stored in EEPROM on the
Main C.B.A. Therefore, before removing the Main C.B.A. or
the TV/Tuner Unit at the user's location, make a note of the
CURRENT LAMP value (value A) in Service Mode (1/3).
Then, after installing the new Main C.B.A. or the TV/Tuner
Unit at the user's location, set the CURRENT LAMP value
to the original value (value A) in Service Mode.
Otherwise, OSD and LED Lamp replacement indications
will be displayed at the wrong time.
Note:
In case it is impossible to make a note of the CURRENT
LAMP value because of a defective Main C.B.A., ask the
customer their daily average use and the approximate age
of the current Lamp. Then, calculate the CURRENT LAMP
value as follows and make a note.
Daily average use
X
(hours)
Note:
The TOTAL value can be set to the original value in Service
Mode (1/3) by similar method:
Before removing the Main C.B.A. at the user's location,
make a note of the TOTAL value in Service Mode (2/3).
Then, after installing the new Main C.B.A. at the user's
location, set the TOTAL value to the original value in
Service Mode.
