PCI-Servo-4A cards not recognized by computer

[Billman926]

After shipping a computer with PCI-Servo-4A cards (which had been working for 2 years), my computer did not recognized several of the cards. These cards are not recognized in other working computers, and both computers recognize other "good" PCI-Servo-4A cards. There is a hardware failure on the cards (I have 10 with this problem). Has anyone repaired PCI-Servo-4A cards with this problem, and is there a "shotgun approach" to replacing a most likely culprit part?
Thanks

Hello,

You can have your cards repaired by National Instruments. Goto ni.com/ask to generate a service request number and then call in with that number to RMA your boards.
