I have a Anders Nicholson 4 in one play, a turntable, cd drive , tape cassette and radio. Cd door will not open when I have it on cd function and push knob to open. The model is NE-GA06. Manufacture date is FE27 2004. Also the tape cassertte does not work. I put it on tape fundtion and put in a tape and nothing plays. I'm mainly interested in getting the CD to play but would also like to play the tape cassette. Any help would be appreciated.
