Philips 8631 won't read anything

I installed my Philips 8631 today, but it won’t read any CD’s or DVD’s. Do I need to update firmware? If so, which is the latest one?

If your Philips 8631 doesn’t read anything, I afraid it’s a DOA :sad:
A firmware flash wouldn’t help. Are you sure the installation of your new drive is correct, cable, jumper setting, no hardware conflicts.
