In the afternoon, a user brought a Hisense 32-inch LCD TV, model: LED32K20JD. The fault phenomenon is three, and the indicator light is off. Disassemble the machine and check the 320V at both ends of the large capacitor. After the power is turned off, the discharge is slow, so that the power supply is not started. After the power-off capacitor is discharged, the secondary rectifier diode is detected to be intact, and there is no short circuit. Plug in again, measure 12V output has 12V voltage, find the motherboard, find a chip capacitor next to the motherboard N100 burnt black, view the drawing, it is 12V filter capacitor, the solder capacitor found broken, the capacitor under the circuit board copper The foil has been blown, the circuit board is scraped off, and the copper foil of the burned portion is connected by a wire, and the chip capacitor is directly removed, and the startup fault is eliminated.
