Len,

"LED voltage drop is the voltage drop across the LED (typically about 1.7 - 3.3 volts; this varies by the color of the LED"

Go to Radio Shack and get a series of colored LEDS and clean up the solder joints on the board and solder a new similar (Same Color) in the through holes. Watch the polarity. Some upper scale electronic stores will tell you the type of diode it is and sell you one.

I occasionally fool around with electronics.
