My medusa back drops started acting flaky. I removed them - a couple bad solder joints and contacts out of alignment. I have to tweak those back targets every so often.

Here is my question and I never noticed it before. When the two green targets behind the drops are hit, the lights on the whole playfield do a little flash or at least dim for a millisecond. The center red target doesn't cause the lights to dim/flicker. It may have been there all along since I did the pf swap a couple of years back but just started noticing it after tweaking the back drops this time. I am using LEDs throughout the pf and bg.

Is this normal or do I likely have a wiring issue somewhere? I checked on line for videos of game play but could not find one that replicated what I am seeing.

thanks,

Great! Thanks, I had really never noticed it before but was testing the drops before connecting them to the pf so the pf was up and it was really noticeable.

I have never noticed the displays blanking but will try to cause it based on the information you provided and post back.

I never got around to checking the display issue today. Keep having to tinker with the rear drops. I went ahead and ordered new 7 new switches. The ones I have for some reason don't want to make consistently good contact. Targets drop but sometimes don't register unless I manually push on the switch.
