When a hardware fault occurs of these data lines, bright or no light is abnormal._x000D_ The failures of computer memory are mainly due to poor contact of the gold pins, wear and tear of the gold pins, broken PCBs, damage to the data line exclusion, open and short circuits in the video memory, and poor memory performances._x000D_ If test flashes, it means that the gold pin is in poor contact. If there is no light, it means that the hardware hasopen circuit failure. Check the wear of the gold pin, whether the exclusion is damaged, and whether the PCB is disconnected._x000D_ Insert the CR2032 battery into the battery holder of test card, or the USB C cable, and then insert the memory card to test._x000D_ _x000D_ _x000D_ Specifications: _x000D_ Component:PCB_x000D_ Size:Approx.15.2x19cm/5.98x7.48inch_x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1Pc Memory Tester_x000D_ _x000D_ _x000D_ Note: _x000D_ 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order._x000D_ 2.Due to the differences between different monitors, the picture may not reflect the actual of the item._x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
