Test board for graphics card ports - Dual AGP and PCI EXPRESS interface

This tester is used to check the presence of open/short circuits or grounds on the connecting elements of a graphics card to a motherboard. Instant visual test thanks to a tray of LEDs.
Operating mode:
First, look for any burn marks or obvious 'breakage' on the graphics card PCB,
Insert the graphics card into the appropriate slot, PCI Express or AGP (no confusion possible, as the presence of coded pins prevents the insertion of a card into a slot that isn't suitable for it),


Insert the graphics card into the appropriate slot, PCI Express or AGP (no confusion possible, as the presence of coded pins prevents the insertion of a card into a slot that isn't suitable for it),


Insert the graphics card into the appropriate slot, PCI Express or AGP.br>Power up the test board with the 12V power supply supplied, then press the switch at the top left of the board: the diodes will light up,
If all diodes light up, then the board's communication with a motherboard is functional,
If one or more diodes remain off: locate the diode(s) by the characters written next to it (a combination of letters such as "ac", or "aa" for example), then turn the test board over. On the reverse side, the soldering points corresponding to the contacts on the graphics board are marked with the same symbols: you'll be able to find the contact(s) in question.
