Why doesn't this bulb illuminate on my digital dash? (not burnt out)
 

I'm replacing all of the lights in my dash to LED and noticed that the circuit board that houses the panel for battery, oil and water temp has a light in it that doesn't illuminate. I've tried replacing the bulb and cleaning the contact but with no luck. Anyone know the reason for this? thanks

could it be a bad contact in the bd or the bd itself

is that bulb dependant on any other boards? because I've got an odometer board that went bad and I'm just wondering if that's effecting it
