I have several problems with Data East Secret service
1.Kickbig whitehouse don't fire.I mean even no balls and tha machine search for them,this coil didn't fire.When I knock the Relay which is connected,coil fires.But even the ball is located on the switch ,nothings happens.I see something strange.When I measure the coil when the machine is off,it show normaly 6omh,but when I turn on the pinball,the value is not constantly-4.0,7.5,5.0 and etc.I don't now where to look for this problem.I measure the diod on the coil and it's fine
2.Anohter mistery.Transisot Q50(3904) blows very ofen.This transisotr corespondending with the outhole,trough 1 2 3.I measure the diods that are connected with the siwtches but no problem.Of course when this transistor blow,coil for the eject hole not working.It blow not every time,it can be on second or fifth switch on/off.It only happesn when turn it on/off
3.I don't now if it's important if the test switch connector must be connected to the MPU.I mean can machine operate normaly if the connector is not pluged in.Because when it's pluged tha machine only say "secret service in digital stereo" and nothing more,it not goes to atract mode.But when is dissconected go to atracted mode and can be played.
4.And one more thing,when I power it on I see three leds-blanking,5V,PIA.When machine works normaly how they must light.Because it light onlye blanking and 5V constantly ,but PIA is off,but it's playable
