Measuring voltage method to find the fault PPC902AE101 3BHE010751R0101 PCB board
The first thing to confirm is whether the voltage of the power supply pins of each chip is normal, followed by checking whether the various reference voltages are normal, in addition to the working voltage of each point is normal, etc.
For example, the general silicon transistor conduction, BE junction voltage at about 0.7V, while the CE junction voltage is at about 0.3V or less.
If the BE junction voltage of a transistor is greater than 0.7V may be BE junction on the open circuit.
