Quoted from Maurice:
I apologise for providing some incorrect info. Upon closer inspection I saw that:
J100, J101 and J103 have a cable in their connector.
J102, called rollover acces, doesn’t have a connector. Seems like this connector never had a cable in it.
The green led near connector J100 & J103 is lit. I see this green led on almost all led boards below the playfield and this led is always on. Green means power is ok.
I didn’t measure anything yet. Wanted to provide correct info first.
Now what to check next?[quoted image][quoted image]
You have power to the board, so it seems likely that the board has just gone bad (unless the ethernet cable has come unplugged or loose at either end).
