AGP PCI-E X16 Dual Purpose Socket Tester Display Image Video Card Checker Tester Graphics Card Diagnostic Description

① The AGP/PCI-E tester is primarily used to test for open circuits and short circuits on the data buses that connect the graphics card chipset, the CPU, and the computer motherboard's PCI interface to ground. ② When repairing graphics card faults such as no display, a blurry, or unstable display, there's no need to measure every single point of the PCI bus interface between the graphics card's gold finger and the motherboard with a multimeter. This graphics card tester can quickly detect CPU open circuits and short circuits and is a common tool for graphics card repair. ③ When repairing a graphics card, if the graphics card isn't displaying, the screen is blurry, etc., first check the exterior for obvious burn marks, whether the circuit board is obviously broken, and whether the voltages in each group are normal. If everything is normal, use the tester to further measure whether the data cable connecting the CPU to the motherboard's PCI interface is functioning correctly. 5. Connect a 12V power supply to the tester, insert the faulty card into the corresponding slot, and press the "Press" button in the upper right corner. The corresponding indicators on the tester should all light up. If they do not light up, are flashing, or show a significant change in brightness, this could be caused by an open circuit or short circuit in the main chip (CPU). In this case, use a multimeter to further determine the fault location. Color: Black. Material: PCB + Metal + Plastic.
