Fluorent Security Lamp with photocell failure - Chase Problem or Replace the device

[mgrablin]

The entrance to our neighborhood has four fluorcent security lamps each with a photocell hardwired onto the ballast circuit board at the base of the compact fluorescent bulb socket. Two of the units will not operate with good bulbs and verified power to the unit. A visual inspection of the ballast circuit board on one lamp shows now obvious signs of failure such as burned components or swelled capacitors. The photocell is a two wire cell soldered to the circuit board which I assume measures the presence of power during periods of daylight. Covering the photocell produces no action. What are the steps to troubleshoot a ballast board of this design and is this typically a problem that is chased or should I just replace the device.
