@phonetalkzzz: Do You Need to Buy Screen Insurance for Your New Phone? Here's What Happened When It Failed When purchasing a new smartphone, many people consider whether to invest in screen insurance. One fan shared their experience of buying screen insurance for their phone, only to have it broken later. Unfortunately, the manufacturer refused to provide a free screen replacement because the motherboard wouldn't power on, making it impossible to verify the serial number. This situation is not uncommon. Although many of us don't fully understand insurance policies or dare to comment on them, it's essential to know that some manufacturers allow screen insurance claims even if the motherboard is non-functional. If you have expertise in insurance, please share your insights in the comments to help clarify this issue. Repairing the screen independently can be costly, with expenses exceeding 2,000 yuan, which is a significant financial burden. To help fans avoid such losses, we decided to open up the phone and inspect the damage ourselves. Upon testing the power supply, we discovered a leakage of about 50 milliamps on the motherboard. Based on our experience, this leakage typically results from a short circuit in the secondary power supply. We removed the motherboard and found it to be in excellent condition, without any prior repairs. Testing the capacitor near the Wi-Fi chip confirmed a short circuit. Using a specialized device, we applied 4 volts to the shorted area, which partially restored the resistance but didn't fully resolve the issue. Employing a thermal imaging camera, we identified the exact location of the heat source, which led us to the damaged capacitor responsible for the problem. After carefully removing the faulty capacitor and cleaning the solder pads, we reinstalled a verified power supply component. Testing again showed normal resistance levels, allowing us to reassemble the motherboard layers and successfully power on the phone. The device was activated, and all functions were tested to ensure everything was working correctly. As a result, we saved over 2,000 yuan for our fan by avoiding the expensive screen replacement. In conclusion, while screen insurance can provide peace of mind, it's crucial to understand the terms and conditions. Manufacturers may have specific requirements, such as a functional motherboard, to honor insurance claims. If you encounter similar issues, consider seeking professional repair services or exploring DIY solutions to mitigate costs.
