Quoted from ignat:I have a quick query. I have sourced a ST:TNG machine locally it looks to be in good condition except for few issues and wanted some advice before purchasing.
Like others have mentioned, this is minor ghosting and is caused by a separation of the clear coat from insert and occurs at the edges. This machine appears to have no ghosting around the shield inserts which is very hard to find in a STTNG. IMO is these inserts are the only thing wrong with the machine, at under $5K USD its reasonably priced. If you have to have a perfect play field you may want to consider buying a new reproduction board and doing a full playfield replacement, either in this machine or another with a decent cabinet and board set.
I wish you all the best in your search.
