HARMAN - KARDON _ FL8350/FL8550_ Carousel does not stop.



     In the event you receive an FL8350 or FL8550 with the complaint: “The carousel does not stop at a given disc position, or passes disc positions intermittently”, perform the modification listed below;


  • Lay the unit on a padded surface.
  • Remove the (7) Black Philips screws holding the Top Cover on; remove cover.
  • In the center of the carousel are a single screw and plated washer; remove these.
  • Underneath the larger plated washer are two smaller fiber washers. These are to be removed Permanently.
  • Examine the larger plated washer carefully. Upon replacement of the larger plated washer and screw, make sure the slightly sharper, stamped edge of the washer is facing upwards.
  • Test the player by inserting one or more compact discs, assure the unit reads discs in all slots, and stops at all positions.
IF THIS MODIFICATION DOES NOT CORRECT THE PROBLEM

  • Lay unit on its side and remove (5) Black screws on the bottom, which hold the front panel to the chassis.
  • Lay unit upright, remove (2) Black screws at top front section holding front panel to the front tray retainer brackets.
  • Pull front panel away, cut plastic cable ties if necessary, and lay the front panel face down on the table.
  • In the center of the carousel, once again remove the single screw and plated washer.
  • Lift the carousel up and off the chassis, towards the front of the unit.
  • Turn the carousel upside-down; in the center is a hollow plastic post. Remove any excess lubricant with a clean dry cloth or paper towel, saving it for re-application. The end of this post must be filed down approximately 0.020” (0.5mm) with a file, Dremel tool, or similar tool. Be sure not to remove too much material and keep the surface even (flat). Remove any debris or shavings when finished.
  • Spread and replace the saved lubricant on the new surface of the center post.
REASSEMBLY

  • Replace the carousel and mounting screw + washer.
  • Replace the front panel, both with the (5) bottom screws and the (2) screws at the top. Note: Make sure any washers that were present between the various brackets and the chassis are reinstalled. Replace cable ties as necessary. Replace the top cover.
  • Test the player by inserting one or more compact discs, assure unit reads discs in all slots, and stops at all Positions
