When the power adapter we use is damaged, or even use it, will you do this, will you repair it yourself? If you don't understand the circuit, Xiaobian recommends not to repair the power adapter by yourself, even if you want to repair it, look for a professional. If you are in the warranty period, you can return it to the factory for repair.
If our power adapter is broken, we can first find a power adapter with the same output voltage and the same output current instead, but the output power must be equal to or greater than the original power supply.
For those who understand the circuit and understand the structure of the power adapter, we must first prepare tools such as multimeters, screwdrivers, soldering irons, solders and other tools.
Now we can take apart the power adapter housing. The power adapter housing has two modes: lock screw and high frequency compression. We must first distinguish which one, some of the screw holes will have a plastic cap to protect, open the plastic cap. You can see the screw. For the lock screw, we can use the screwdriver to twist the screw out to open the case. For the high-frequency compression, we only have violent disassembly, and the steel discs and hammers are disassembled at the four corners of the press. Be careful not to damage the internal structure.
After we open the case, check to see if there is any abnormality, such as whether the component is broken down, the capacitor is invalid, or if there is any solder joint. Then use a multimeter to check if there is any problem with the power cord, and if the component and the size of the mark are consistent, check it. Find out the specific point of failure.
After we find the faulty components, we must pay attention to the same size as the original when replacing the components. In particular, the mos tube and the IC chip are the same as the brand model.
Self-service power adapter repair requires not only strong hands-on ability, but also solid professional knowledge, so non-professionals should not repair it.
