Sony HCD-M35WM Compact Disc Deck Receiver The main unit powers on and the screen displays, but the CD and cassette playback functions do not work and the trays do not open. The cause is unknown, and there may be other reasons. Only the screen functions, and no other features are usable. Therefore, it is being sold as a defective item. No remote control or box is included; only the main unit will be shipped. The exterior is very clean, as shown in the photos.
