MEMORY IC REPLACEMENT
IC1391 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, it should be performed the re-adjustments following to the "Electrical Adjustments". The data of lamp replacement monitor timer is stored in the IC1391. Please note that the lamp replace counter is reset 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 adjustments to the replaced IC, refer to 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 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 readjustments following to the "Electrical Adjustments". In this case, the lamp replace counter can be kept the value as before.
