In spite of cleaning carefully the laser thingy my machine will not recognise any disk keeps coming up with a 'No Disk' error. Stopped suddenly whilst playing a music cd. Had stereo for about 10 months. Other fault is that I can't always select usb track via remote although everything else works can even bounce infrared off windows to select function etc. Sometimes if I unplug the power supply and restart I can select a usb track.
