I would make sure. And double check.
Before I bought a new FireWire card I sent my camera in to irvine to be fixed. They sent it back saying that there wasn’t anything wrong with it. I hooked it back up and the problem was still there.
So then I knew the problem wasn’t the camera.
The reason why it’s blinking is because the camera recognizes that something is plugged in. But the computer doesn’t see it. In my case it was the FireWire card. I can only imagine that it’s the FireWire card for you too.
Have you used any other devices that use the same FireWire port? And if those work then I have no clue. In this case, the shlt has already hit the fan and you should send the camera in.
But if you don’t want to go through the hassle, make sure it’s not the card. Good luck bro.
