What to do if the contact of the mobile phone charger is bad? And the maintenance problem of the charger!
One: What should I do if the phone charger has bad contact?
1. Generally, there will be some problems with the original charger, such as the touch screen cannot be touched after plugging in, or the charging is intermittent, so the original should be replaced;
2. There may also be a software problem, you can try to change a system;
3. After turning off the phone, use the red wire positive pole to touch the tail pin of the motherboard in turn to see if there is a charging pin. After finding it, solder it with a soldering iron and try it. If it does not continue;
4. Try to replace a R104 exclusion near the charging tail plug;
5. Try to change the charging transistor;
6. See if the output voltage and current of the charger head match the original. If the charger output is generally 350-400MA, this will not achieve the effect of charging the mobile phone. The output is replaced by 550-600MA. Can be solved;
Two: Maintenance of the charger:
1. Waterproof and moisture proof:
As an electronic product, accidentally entering water or being exposed to humid air when not in use for a long time will cause different degrees of corrosion or oxidation to the internal electronic components.
2. Shockproof and shockproof:
The mobile phone charger is actually a fragile component, and the internal components can't withstand the beating. Especially to prevent accidental landing during use. Do not throw, knock or shake the charger. Rough treatment of the charger will destroy the internal circuit board
3. Anti-strong chemicals: Do not use strong chemicals, cleaning agents or strong detergents to clean the charger. To remove the stains on the exterior of the charger, scrub with a small amount of absolute alcohol on cotton.
4. Discharge static electricity during cleaning: clean the charger and charging interface regularly. When cleaning, use a damp cloth or an antistatic cloth. Never use a dry cloth (electrostatic charge)!
5. Protection against cold and heat: Do not place the charger in a place where the temperature is too high. High temperatures can shorten the life of electronic devices, destroy chargers, and deform or melt some plastic parts. Do not store the charger in a cold place. When the charger is working in a cold environment, when the internal temperature rises, moisture will form in the charger, destroying the circuit board.
