So dumb me... I was working in my machine with the power on.. something hit something that it should'nt have and now all the lamps on "Row 2" are stuck on.

Game functions as normal except for these lights.

Never really dived into this before... But I'm guessing a Diode? Or Transistor on Q89, on the power driver board?

Any tips? I did order a logic tester a few days back. But all I currently have is a simple Meter

Probably not a diode as each lamp has one but more then likely one of the components that drives that row like you said a transistor.

Yes test that transistor Q89 with a multimeter and see if has shorted..your simple meter will do just fine

No go, replaced Q89 and the row is still on.
