No Key Start – Drive/Display Test
Condition: No one is exercising on the unit; battery voltage is appropriate; the display lights briefly
when the ON key is pressed but shuts off as soon as the ON key is not pressed.
Response:Test D7 diode voltage: Place the black probe on the negative end of CN2; place the red
probe on the positive end of diode D7. Normal voltage: 0~0.5V. If the voltage is normal, the drive
board automatic shut off function is malfunctioning. Replace drive board IC U10(HT7044) or
U3(40106) or capacitor EC11(2.2UF) or transistor Q5(C1815). If voltage exceeds 5VDC , the display
board (“shut off” signal emission) is malfunctioning. Replace the display.
