KX-FP342BX 6.6.7. DIGITAL BOARD SECTION When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem. The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.) The first step is to check the power source.
Page 98
KX-FP342BX Digital Block Diagram You also need to check the signal lines listed here [List 1] when the unit fails to boot up the system. Those signal lines should remain normal. Other signal lines are not directly related to that failure even if they have faults or troubles.
Page 99
KX-FP342BX Normal Wave Patterns Remarks: When you use an oscilloscope to judge whether a signal to be tested is normal or NG, perform the signal check in exactly the same order as in [List 1]. (If the ASIC fails to access the FLASH ROM, the ASIC cannot access DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals.
