PC AGP PCI-E X16 Dual-Purpose Display Video Graphics Video Card Checker Tester Card Diagnostic Analyzer Tool Repair Tools New Product Description:_x000D_ AGP/PCI-E tester is mainly used to detect open circuit & short circuit of the main chip of the computer display card. When the computer graphics card malfunction is monitor no display or unstable display, there is no need to use a multimeter to measure the resistance of the graphics card's connecting finger to the ground one by one. Use AGP, PCI-E tester can detect GPUs open circuit, short circuit and other faults so quickly, and the accuracy rate reaches 100%. This tester is a necessary tool for repairing the graphics card. Instructions:_x000D_ 1.When repairing the computer display card, if the graphics card is not displayed, first check whether there are obvious burn marks on the appearance, whether the PCB has obvious disconnection, and whether the voltage of each group is normal. If it is normal, use a AGP/PCI-E tester to further measure whether the BCA is normal._x000D_ 2.The TypeC interface is used to power the tester, which supports fast charging or power bank power supply, and the 12V power supply 6P interface inside the computer. Plug te faulty graphics card into the corresponding slot and press the switch in the upper left corner of the tester. At this time, the corresponding indicator light on the tester should be fully on. If it is not bright or there is a significant change in brightness, it is necessary to use the multimeter to further determine whether the fault is caused by dirty connecting finger or the open/short circuit of BGA. _x000D_
