    KX-FP701CX/KX-FP702CX 12.5.5. 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 118 KX-FP701CX/KX-FP702CX 12.5.5.1. 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. As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 3.3V (H) and 0V (L).
  • Page 119 KX-FP701CX/KX-FP702CX 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.

  • Page 121 KX-FP701CX/KX-FP702CX After the power is turned on, the ASIC initializes and checks each IC. The ROM, DRAM, and modem are checked. If initialization fails for the ICs, the system will not boot up. In this case, please find the cause as follows. REFERENCE: 12.5.5.2.NG Example (P.123) 12.5.7.Power Supply Board Section (P.126)

No handset transmission / reception and no monitor reception Perform a signal test in the ITS or the NCU section and locate a defective point (where the signal disappears) on each route between the handset microphone and telephone line (sending), or between the telephone line and the handset speaker (receiv- ing), or between the microphone and the telephone line (sending), or between the telephone line and the speaker (receiving).

This comes from our experience with experimental tests.

If D101, D102, D103 and D104 are short-circuits, F101 will melt (open). In this case, replace all of the parts (D101, D102, D103, D104, F101). (Q101) The worst case of Q101 is a short-circuit between the Drain and Gate because damage expands to the peripheral circuit of Q101.
