can;t find my problem in the manual for the Aiwa CSD-td49. Problems started after unplugging unit and moving it to another room and moved it back to my bedroom. Now when the Band Button is pressed it displays MW or SW or FM does not/will not display AM. Regardless of what station is displayed on the tuner or what band I receive only one AM station! Very odd. Tried unplugging the unit and pressing CLEAR to no avail. Please Help!
