(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.
