Update: Pulled the drop target pcb; Reflowed every solder point; Cleaned the opto with a q-tip dampened with isopropyl alcohol.
Put back in game; Drop target reset! yes!
But sometimes drop target will reset and other times not.
Powering up and on a new game, it'll still stay down.
I have not checked the transmitter yet. Need to get out my digital camera or head to RS for a Infrared card.
For the record, what is the normal process of what the Drop Target is supossed to do during game play?
Will it reset only between players or the next ball?
