Hi All,

While changing several lamps on a SouthPark playfield, i noticed the underside of the playfield-inserts (and the surface of most lamps) have a fine layer of black powder, not sure what or how it got there, almost like there's been a serious smokey flameout within the machine, but nothing appears fire damaged within the entire machine.

After replacing the DMD today, i also found this same black powder on the inside of the DMD plastic window.

The powder wipes off very easily with a tissue


My new theory is that *maybe* the previous owner had an open fireplace in the same room as the pinnie (or next room) and the pin has been collecting the soot over the years.

Anyone seen this before and know what this might be?
(in case others are seeing this in their machines).

MM.

My LAH was similar.  Playfield side - thick layer of tar over plastics.  Underside was covered in a fine black dust.  It did have black rubbers but NFI what it was.  Cleaned up well.
