Power management chip: it is a mass-produced product with dim light or no light. This material has also been used in succession. This time, 11 defects were found in work order 50, and the bad light is dim or no light. There is no schematic diagram of the circuit, and the actual circuit can be restored to normal by replacing the LED driver. Here, confirm that the material is damaged. Check that the temperature curve does not exceed 260 degrees. It should be caused by static electricity during transportation and storage, resulting in internal MOS failure, poor current output capacity, resulting in abnormal light emission, or individual materials have been damped, vaporized during the heating process, damaging the internal structure, resulting in abnormal light emission. The customer requires return and20220701-DIP2 2022-7-1 9-17.pdf replacement. Please confirm. Thank you.
