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.
