Quoted from Rob_G:Seems like a lot of the GI (general illumination) is out on your game, or it's just when the picture was taken?
As noted in the OP from me, my room is dimm and it was a single shot of the machine (All the GI were not activated) and the picture presents my lights are not working. Rest assured all the lights seem to be working, minus a light at top-right near Pop bumpers.
I am new to using Stern's internal service test menu. I'll read up on it, but is there a system check to test if all lights light up and report which one's appear to be "not working".
