   Hi,   
      
   Don't replace any resistors unless they are physically damaged.  Resistors   
   don't go bad unless too much power is sent through them, then they easily   
   appear damaged.   
      
   Capacitors on the other hand can be a problem, but test the circuit one   
   capacitor at a time with an oscilloscope.   
      
   Good Luck.
