6 Inspection of electrical section (AJDP circuit board)

During inspection of the electrical section, remove the AJDP
check the board and check at CN1, CN4, TP4, and TP6.
1. Check the supply voltage
 of TP0-CN1: +5.7 to +6.3 V
2. Check supply voltage within the circuit
 of TP0-CN4: +4.75 to +5.25 V
TP 0 to TP 1: +3.0V ~ +3.6V
2. Check the signal waveform
