I have an undercabinet fluorescent lamp fixture that suddenly quit
working. After verifying the tube works in another fixture & pulling
the board out of the housing, I checked all components & they seem to
be OK except for a component that looks like a black diode without a
band. It appears to be open & has DB3 printed on it & the PCB next to
it. I looked on line & have not been able to find the PCB name for a
"DB" device. Any help? Thanx.



Not sure what that is, but if all else fails you can probably pull the
ballast circuit out of a cheap CFL.
