Talented 18-Year-Old Girl Repaired And Restored A Speaker For An Elderly Woman. Amazing!

Talented 18-Year-Old Girl Repaired And Restored A Speaker For An Elderly Woman. Amazing! She heard that the elderly woman she had helped repair a TV before needed her assistance once again. The woman called her and said she needed help fixing a speaker that had not been used for a long time. She wanted to be able to listen to music and have some entertainment while living alone. When she arrived at the elderly woman’s house, the woman showed her the speaker that was placed in a corner. She tried turning it on, but it didn’t work. She decided to take it outside to repair it in a more open and well-lit space. She removed all the screws carefully. After some time, she had fully opened the speaker and took out the circuit board for inspection. While cleaning off the dust, she noticed that a solder joint on the power supply was broken, likely due to being left in a damp place for a long time, causing oxidation, rust, and wear, which made the solder joint come loose. She carefully used the soldering iron from her toolkit to re-solder each joint. After a while, she finished soldering, then tried turning it on again, but it still didn’t work. She then used a specialized meter to check the IC and capacitor pins on the circuit board. She measured each IC pin and each capacitor pin carefully. Once she identified which capacitors were weak and needed re-soldering, she carefully re-soldered them to ensure they were secure. After quite a long time, the soldering was finally completed, and she tried turning the speaker on again. It was amazing that it finally worked. She found that the main reasons the speaker hadn’t been working were: The power cable had a broken solder joint, which she carefully re-soldered. Several capacitor pins were loose and weak, which she re-soldered securely. #repairgirl #geniusgirl #girlrestoration #mechanicgirl #talentedgirl
