Static measurement: Let the board be suspended in a close-up mode, according to the logical principle of the circuit or chip output and input of the logical relationship between the use multimeter measuring the relevant points to analyze and judge the cause of troubles.
Dynamic Measurement and Analysis of Law: the preparation of specific procedures or artificial assertion normal conditions, the machine is running, measured with the oscilloscope to observe the waveform components, and compared with the normal waveform in order to determine fault location.
As the control logic on the motherboard increasingly integrated, so its logical correctness, has become very difficult to determine by measuring. Recommend that you first determine the relationship between the logic chip and a simple resistance-capacitance components, and then focused on the logical relationship failure is hard to determine the large-scale integrated circuit chips.
