Problem with CEC transport

Hello all
 

I have a CEC TL5 transport, and it is the Japanese model, so I cannot get it serviced in the United States. All of a sudden the transport starts freezing up after two or three minutes. The disk continues to turn and I have recently checked the belt, so I'm pretty sure that isn't the issue. Any ideas as to what the problem might be, how to fix it, or where I could take it in the United States for service?
