In June I had my 800 player fixed by Marc Koval with a new transport and linear power upgrade. As of yesterday everything was fine and I have been extremely impressed with the sonic improvement.

When I insert a DVD audio or DTS disc the player tries to read it and then states "NO DISC" These are discs that a few days ago were playing without issues. Normal CD's are read and play normally.

Can anyone help please diagnose this problem?

Thanks

Alan
