Hi, Try this. Hope this helps and I have the link here to the manual.
Processor Reset
If the AVr behaves erratically after a power surge, first turn off the front-panel
main
power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back
in and turn the AVr on. If this procedure doesn't help, reset the AVr's processor as
described below.
note: resetting the processor will erase all user configurations, including speaker and
level settings, and tuner presets. After a reset, reenter all of these settings from your
notes in the Appendix worksheets.

To reset the AVR's processor:
1. press the front-panel Standby/on switch to place the unit in the Standby mode (the
Standby Indicator led will turn amber).
2. press and hold the front-panel Standby and memory/folder buttons until the reSet
message appears on the front-panel message display.
3. press the memory/folder button again to reset the AVr's processor.
If the AVr does not function correctly after a processor reset, contact an authorized
harman
kardon service center for assistance.

All it needs its a hard Reset press the power button once its on standby mode press surr botton for 5 sec and it should reset

With mine, it was the drive belts for the cd drawers, which were stretched and rigid. Open the case. Remove the 4 screws that hold down each cd drive. Push the drives out enough so you can pull the silver facing off the sliding try by pulling it up. Now you can lift out the cd drives, removing all the connectors as you go. Flip the white plastic slider underneath each drive and you can mechanically open the slide tray. This reveals the little motor and rubber pulley belt that operates the slide tray. If the belts are broken, perished, rigid or something, get something similar from your local electronics parts store (a couple of bucks each belt), and reassemble.

I had similar problem with both drawers. The belt from the drive motor to the drawer pulley is worn. mcmelectronics.com has two belts 42-1050, 42-045 that are close enough in size to work. Remove cover, press down on tray, slide tray forward about half way and you will see the worn belt. Total cost of fix is about $12.
