well i went to play my getaway and it said pinball missing and game started it fires all the balls.well i did a switch test and figured all of row 7 isnt working since none of the switchs worked or did any thing when i touched them.i also did the plug remove testing and found for sure the row is dead. i get no reading on plug j206 the purple and white wire. so i guess since chip u19 controles switch rows 5.6.7.8 i will replace this chip if no help.then i will replace chip u20 that control the switch matrix what do you think im i on the right track thanks
