The chip capacitor can be judged by the following methods:

Method 1: The resistance value of the general small patch capacitor is infinite, and the resistance value is abnormal. The capacity becomes small and cannot be measured by a multimeter. Replace the capacity directly.

Method 2: A safer way to ground the two poles of the multimeter with one pin and measure the two ends of the capacitor respectively to indicate a short circuit.

Method 3: If the capacitor of the small patch is short circuit, it can be judged by online measurement with a multimeter. If it is open circuit, because the capacity is too small to be measured with a multimeter, you can use an electric pen to connect to the 220V live wire, put the pin of the chip capacitor on the pen cap of the electric pen, see whether the neon bubble is luminous, the luminous capacitor is good, otherwise the circuit is broken. 220v voltage, do not experiment on the board.

Method 4: The resistance value is infinite, the resistance value is zero, and the other should have some small changes.
