Audio Systems: 95 ford explorer stock 6-disc cd changer, dust speck, having computer

Question
well, my cd changer is very screwy.  the magazine goes in fine and when a cd gets selected it will read it for a few seconds (without playing any music) and then pass to the next cd.  this continues with all 6 CDs and after all CDs have been "read" it says "no cd" and goes back to my am/fm radio.  i've checked the CDs inside the magazine for any scratches, but there aren't any.  is it possible to fix this by myself? should i get it professionally repaired or get a whole new cd changer?  -thank you

Answer
first thing i would suggest is to try a lens cleaner cd several times, could just be a dust speck on the lens, if that doesn't work, i'd consider getting an exact replacement from a junkyard to save bucks. repairs are quite expensive....sorry for the delay in answering, having computer problems....not my area at all..lol
