I have the MX-NF810 Mini disc player/recorder with the RM-MC37LT remote control/radio. The on/off switch for the radio just doesn't work (it used to, but it doesn't anymore). The disc player clicks when I press the button so there is some connection but the radio does not come on. However, I can still control the disc player function from the remote. I am wondering if there is a simple solution to this. If not, what are my chances of getting if fixed/replaced? Any suggestions, appreciated. Angela
