Not sure of the best place to post this... I have a 19" LCD TV/DVD combo unit and recently the drive stopped spinning properly. I got a replacement drive off the supplier and connected it up and it has the same problem. The spins intermittently about a quarter of a rotation every 2-3 seconds.
The supplier has given me a replacement board and several cables which have all been replaced but it still has the same problem. They've also tested both drives and they work fine in other units.
