I have bulb 55 in the lamp matrix issue. It is over left ramp, left light. Machine is all LED. This one bulb will not light during attract or gameplay. It will light proper in isolated lamp test mode however. I've swapped bulbs, that isn't issue. Anyone have any input why it will work in test, but very dim (almost off) otherwise? Adding in: it's only one acting in this manner. All other rows/columns are working proper.

Diode on the lamp socket may have a bad solder joint or be broken or has failed. Its purpose is to isolate a single lamp from all others in the same row or column in the matrix. Use a digital multimeter to test diode.

One of those lights only lights when you get multiball or you need to shoot the ramp to start multiball. For some reason it doesn't light during attrack or regular game play. Once you get to ball three start multiball, it should light.

Thanks guys, will check this weekend. Doesn't affect game play, just annoying when you look at it.

Quoted from Djshakes:

So went through the lights again and sure enough it lights up only at certain times in game play. Very strange that, but now it won't be on my mind anymore.

Thanks!
