Insert lights are erratic , most are on permanently on, not sure what is causing this? Tried a spare lamp board same problem?
If you've got a logic probe or multimeter, check pin 1 on any of the 4514 chips on the Lamp Diver board. If this signal is stuck high (or measures close to 5 volts), you've got a connector issue with the the Orange-White wire between the MPU board J1 Pin 11 and the Lamp Driver Board J4 Pin 13. An open circuit on this signal will cause most of the feature lamps to appear on or flicker.
Thanks, will do! Yep i have a logic probe.
