Lately my clock and radio do not work. I have checked the fuse and even put a new one its place while the old one still works. I have pulled the battery cables of the battery thinking that it will reset the clock and radio but it didn't. I even pulled the radio out and checked the wiring on back of the unit as well. Is there a fuse inside the radio as well or what can I do? If I have to replace it I want to put the same one in it not no cheap imitation.
