I just picked up a beautiful Stern ST Premium today. The model has the changing multi colored LED lights under the clear PF inserts and for the GI. They were working perfectly and the game was playing like a dream. Got it home and after playing a few games I noticed that there were moments that all lights (GI and Controlled) would go dark. Then all of the sudden the whole game went dark except the Start button on the front of the gams, Punch It Button on the Hold Down Bar and the coin lights on the coin door.
This reminds me of the problems that JJP was having with the first generation of the multi-colored LED PF lights ON WOZ pins they were building. I currently have a WOZ and have never had to deal with this issue.
Anyone have a suggestion on where to start looking. I have a feeling it's a connection issue I'm not really fimulay with this era of pins to know for sure and where to start.
Thanks for the help, Dave Schulpius
