I've only just realised that the triangular signed cards on my LE at the bottom of my playfield should be illuminated.
Looking at the manual, these both seem to be on Lamp #277 along with the rest of the lower play field GI so I don't think its an issue with Node Board 8 (but I disconnected and reconnected the connector CN15 anyway which made no difference).
It seems that both come off a single connector to the loom (see pic) - I've disconnected and reconnected both sides of that (both connectors are female with a male-to-male joining piece inbetween.
I'm not sure what to do/check next. Its possible both LEDs are faulty (but probably unlikely), should I just connect up a spare LED to the pins on the joining piece and see if that works? Can I measure for a voltage across those pins (and what am I looking for).
Are there any other connectors/joints I may have missed? Node Board 8 is at the top of the play field so the wires run down the table but there are loads of wires so its hard to trace (but I can't really find any breaks).Connector which feeds LED (resized).jpgGI 277 Test (resized).jpgLED under panel (resized).jpgPanels not lit in red triangles (#277 test is on) (resized).jpg
