There are several reasons why an iPhone 13 may not turn on. In this case, someone purchased a second-hand iPhone 13 that cannot boot and asked us to fix the issue. Many second-hand devices face problems such as failing to boot due to prior drops or exposure to water. This guide will walk you through diagnosing and fixing an iPhone 13 won’t turn on<\/a>. Whether you are a repair technician or a DIY enthusiast, follow these steps to troubleshoot the problem and revive the device.<\/p>\n\n\n\n

The phone owner purchased a second-hand iPhone 13 and found it won\u2019t boot up. This could be due to physical impact or water exposure, but without a clear history, we’ll need to investigate further.<\/p>\n\n\n\n

Disassemble the iPhone<\/h3>\n\n\n\n

Begin by carefully disassembling the phone to access the motherboard. Check for visible signs of damage, particularly water exposure.<\/p>\n\n\n\n

Check for Water Damage<\/h3>\n\n\n\n

Upon inspection, if you see corrosion or residue on the motherboard, water damage is likely the culprit.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Prepare the Motherboard for Repair<\/h3>\n\n\n\n

\"Remove<\/figure>\n<\/div>\n\n\n\n
\n

Remove the black protective film and any foam surrounding the connectors. Store these safely for reassembly.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Power Test<\/h3>\n\n\n\n

\n

Connect the motherboard to a DC power supply to test booting. If you observe an unusually high current and the phone won\u2019t boot, suspect damage to a chip or component on the board.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Separate the Motherboard Layers<\/h3>\n\n\n\n

Place the motherboard on a heating platform. Use a hot air gun in tandem to evenly heat the board, reducing the risk of poor soldering caused by overheating. This makes the process faster and safer.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Conseil :<\/strong> Heating with both a hot air gun and a heating platform reduces the chance of causing additional damage to the board due to uneven heat.<\/pre>\n\n\n\n
Inspect the Damaged Area<\/h3>\n\n\n\n

Once the layers are separated, locate any obvious areas of corrosion. Use a thermal imager connected to the DC power supply to identify damaged components. In this case, a capacitor appears damaged and must be replaced.<\/p>\n<\/div>\n<\/div>\n\n\n\n
