1. When the device is connected before the u disk, the voltage of the usb port is high, causing the main control chip on the u disk circuit board to burn. So the u disk will quickly hot;
< br >
Solution: need to replace the main control chip on the circuit board of the u disk;
< br >
2, the u disk accidentally water, the circuit board rose copper rust, resulting in short circuit on the pcb board, so the u disk will be very hot;
< br >
Solution: Repair the copper rust on the circuit board to avoid short circuit on the pcb board;
< br >
3, u disk mixed with metal chips, resulting in short circuit on the pcb, so the u disk will be very hot;
< br >
Solution: Clean up the metal chips mixed into the u disk;
< br >
4, the quality of the u disk is not good, in daily use, the flash flash chip welded on the pcb has a physical failure, the internal short circuit, the so-called burned, so the u disk will be very hot;
< br >
Solution: Replace the USB flash drive with a new one.
To solve the problem of ideal L7 vehicle U disk heating, you can try the following methods:
1. Ensure that the U disk is in good contact with the car audio to avoid loose heat.
2. Reduce the load of the USB flash drive, delete unnecessary files, and ensure that the memory space of the USB flash drive is sufficient.
3. Avoid using the U disk continuously for a long time, and try to use it at intervals to give the U disk heat dissipation time.
4. Use high-quality U disks, avoid using low-quality products, because low-quality U disks are easy to heat.
5. If the problem still exists, you can consider replacing the car stereo or consulting professional technicians for maintenance.
