CAUTION:
1.
Be sure to make a note of the CURRENT LAMP value (value A) in Service Mode (1/3):
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.
