Yes. We have 2 node issues at the moment. Both games bought new and HUO
1. GBLE backbox lights out. Stern have come up with a solution (not replacing CPU board). Not sure on cost (If any)
2. GOTG Light board Node 11a. Stern have sent out a replacement free of charge.
Stern have been fantastic to deal with as always.
Great idea looking to collect real data. I am not sure what you are looking to achieve from your poll. Something to think about. A game in a tournament (with 30 people there) blows a node board. Everyone there will answer your poll "yes" including the owner. Reality is only one owner with one node board has actually had an issue.
