Service Adjustment Menu Operation
Memory IC on the main board stores the data for
the service adjustments, and should not be replaced
except for the case of defective device.
If replaced, the re-adjustments are required following
to the “Electrical Adjustments”.
The data of lamp replacement counter is stored in the
Memory IC.
Please note that the lamp replace counter will be
reset when the memory IC is replaced.
(Lamp replace counter cannot be set to the previous
value.)

caution to memory Ic replacement
When memory IC is replaced with new one, the CPU
writes down the default data of the service adjust-
ments to the replaced IC as the mentioned on the
service adjustment 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
memory Ic is not defective)
When the main board is replaced, memory IC should
be replaced with the one on previous main board.
After replacement, it should be required to per-
form the re-adjustments following to the “Electrical
