关于电击法的维修思路 一下是我从国外的网站上面看到的 共享给大家
If the 3.3V Short-circuit: First test USB port DATA-, DATA + is short-circuit, if the short-circuit the Southbridge bad.
2, from the inductor, sense resistor or break off, if the first half of the short circuit test power supply IC, MOS controlled under control, if the latter part of short-circuit the test filter capacitor, reverse diode, the load.
3, electric shocks Law:
Voltage: 1.5V-3.3V
Current: 0.8A-1A
(3.3V-voltage short-circuit, the first test clock IC inductor, electric shock after touching hot chip availability)
Added: shock France
In the short-circuit office, plus electricity, plus there are large electric current, water failure, you can use this method to get, as some leakage, plus TVU current, and are available to this method
The CPU with the power supply IC removed after the short-circuit combined with the voltage to zero after the first voltage is transferred gradually increased to observe the current, when the current
To 500mA or so, a peek at his hands explore whether there is Dongdong fever, if any, that is, the Dongdong bad, if not,
Description is the motherboard short circuit, disconnect the power after this time will be transferred to the maximum voltage (preferably without short-circuit protection) 15v or 20V power supplies are available in Table 2 in series a heightened voltage, the voltage added to the short-circuit point (do not directly connected, so that the table gray or bad, with the touch-type, that is grounded at one end, with the slightest positive short-circuit point, under normal circumstances short-circuit point in the high-voltage high-current, under which burned off as heat, short-circuit point will sparkle
