Just got NBA Fast Break, in really nice shape. The back part of the machine seemed kind of dark so I took on the task of swapping out incandescent bulbs for LEDs.

Everything was going great until I got to the last bulb!Literally the last bulb. Upper left hand corner under a ramp. Like most of the other GI replacements I did I was attempting to unscrew the socket from under the playfield. Unscrewed it, put in an LED and all of a sudden the top part of the playfield including the lane roll overs are dark.

What did I do?

Not sure if it is related but not to be deterred by one screw up I went on to swap out bulbs in the backglass. I can't remember what was lit and what wasn't before I made the swap. Regardless, now only a small handful of lights in the backglass are lit.

Don't know why I didn't think to look there first. Thanks.

Fuse F114 was blown. It controls some part of the GI but I can't tell what. I'll pick up some fuses tomorrow and see what happen. Got to help somewhere, right?

Replaced the fuse. The GI looks good. Thanks.

Didn't help the back glass issue though. I'll repost to try and conquer that.
