james_s:
What do you get if you check AC volts across that capacitor? If the capacitor is shot the display will flicker.

Electro_Jr:
Capicator C523 shows 0.01-0.009V measured in AC   
Capicator C522 I checked it for comparison and because it was right beside C523 didn't show any voltage. 

Electro_Jr:
I'll add that both capacitors are 0.1uf Ceramic.  If it matters.

james_s:
Oh, I assumed we were talking electrolytic capacitors, ceramic caps almost never fail.

Electro_Jr:
How would a bad capacitor show up?

For example on the one in question, I tested it across it in AC mode with a multimeter.   If it were bad what readings would I see?
