models:

TIP#
HKTT2003-06
Complaint:
Unit Will Not Play or Recognize a Disc, “Skipping”.
Possible Problem:
Misalignment of the top cover and rear panel.
To test, attempt to play the unit with the top cover OFF. If symptoms persist, troubleshoot further. If the
unit will play with the cover OFF, the problem is caused by a misalignment of the top cover and the rear
panel. When the screws are tightened on the top cover, at the rear of the unit, the CD mechanism may
“warp” upward in the area of the clamper arm, which causes a “Will not Play” symptom, which shows up as
an unusual delay, with the word “Disc” in the display, after the “Play” button is pressed.
Solutions:
Washers can be added to the top rear screws to fill the gap between the top cover “lip” and rear panel.
Alternately, a spacer can be constructed of fish paper, plastic sheet, or similar material, that will fit
between the Disc Clamper and the inside of the rear panel. Choose thickness as necessary.
