And device called "CR" is proabaly a diode used in the rectifier stage
of the power supply.  If this is open, then the voltage will be low on the
output.  If this is shortted, then the voltage will be WAY to high, and proabaly
blow the fuse, or worse!
 
If you have an ohm meter, you can test this part by removing it, and then 
make an ohm check.  In one direction it should read low (1-100 ohms) and the  
other should read high, like 10 times as much.
