3 lamp board issue

[Flyte]

Hey gang

Any idea how I can replace or fix this for my twilight zone? Lamp L2 just doesn't work and it's not the bulb or the housing.

Have you tried resoldering the pins on the board? The solder holding the pins is often cracked on these lamp boards. I have had to resolder loads of them.

+1 Its worth reflowing all of the joints on a light board like that, including the pads that the contacts on the lamp holder slide accross. The pads often have divots in them that makes the connections unreliable.

If that doesn't work it'll be the diode

thanks guys I'll give that a go!

I'd say it probably is a cracked solder joint as mentioned, but if none of the above work it could be a wire come adrift elsewhere on the row or column that L2 is on. Are all the other feature lamps working?
