This Marantz DV6200 fails to play the DVD. It does plays CD's perfectly, but using a DVD you can see the Laser head is trying to focus, the tracking sled is moving towards the center of the DVD, the disk spins up and this proces repeats itself 3 times and after that NO DISK is displayed. The DVD cannot be removed using STOP/OPEN, I have to reintialize main power.
Any suggestions what to troubleshoot and/or replace?
TIA Brasto
