Quoted from tron1969:
Won't stern replace the playfield due to the ghosting bump?
It depends. I actually had mine replaced. You send photos to Chaz at Stern. They have someone look at photos and I think they have a threshold of how much ghosting is necessary to replace the playfield. I pulled the playfield(it's only a handful of of connectors), wrapped it up and drove it to stern. They had another populated playfield for me waiting. Brought it home, reconnected the connectors in 15 minutes and it was up and running. Done deal.
If you're out of state, they'll ship you a box to send your playfield. It's really a painless process.
