LED 'Ghosting' On a Modern Stern

[Marvello]

Phil has emailed Stern about this but thought I'd see if anyone else has had a similar issue on a modern Stern.

I've got 2 'ghosting' LEDs on my Stranger Things, the 'D' and '2X'. I spoke to another member who had a similar issue on his AIQ and said it sorted itself out with a code update. I would imagine everyone would have the issue though if it was code related?

I've given the wires a gentle wiggle and reseated the connectors that go into the board but no change.

Could be a bad component on one of the node boards. Either the MOSFET(s) driving these lamps, or the serial-to-parallel 74 chip before that.

I've got it on mine - does yours actually happen during gameplay?

The 2 in question are semi-lit when they are supposed to be off. They light up fully when they are supposed to. This is the case whether I'm playing a game or just with the machine switched on.

I thought mine went off when game started- let me check tomorrow.

Zero ghosting on mine, fully off until they are meant to be on [emoji106]

I was just searching for advice about this actually... I noticed that my new TMNT Pro has this exact issue.

It's one LED in the middle of the playfield. Have reached out to Pinball Heaven but likely need to wait for Stern I would assume!

A replacement lower left LED board has resolved my issue. Thanks Phil/Pinball Heaven
