IC1391 on the main board stores the data for the ser-
vice adjustments, and should not be replaced except
for the case of defective device.
If replaced, it should be performed the re-adjustments
following to the “Electrical Adjustments”.
The data of lamp replacement monitor timer is stored
in the IC1391.

when the memory IC (IC1391) is replaced.
(Lamp replace counter can not be set to the previous
value.)

Caution to memory IC replacement
When IC1391 is replaced with new one, the CPU
writes down the default data of the service adjust-
ments to the replaced IC, refer to the service adjust-
ment table. As these data are not the same data as
factory shipped data, it should be required to perform
the re-adjustments following to the “Electrical
Adjustments”.
Please note that in this case the lamp replace counter
will be reset.
●
Caution of Main Board replacement (in the case
IC1391 is not defective)
When the main board is replaced, IC1391 should be
replaced with the one on previous main board. After
replacement, it should be required to perform the re-
adjustments following to the “Electrical Adjustments”.
