Now it's my turn to have a problem with Cleopatra. I have the Pascal board all in one and suddenly the Lamp L16 on playfield that goes to connector A3-j5 pin 3 green-black-white stays lit. I swap the cables with lamp L15 on playfield to be sure that there is no problem with socket. And the lamp comming from the green-black-white cable remains lit. So for sure the problem is not with the lamp socket. I checked pins on connector A3-j5 and it seems to be ok. All other lamps from connector A3-j5 are ok. I unpluged the connector A3-j5 and i put my multimeter on pin 16 (ground) and pin 3 but no voltage present. in any other pin i have voltage Do you have any ideas what should i look for?

Thanks to Mr. Pascal problem solved.

after burning 7 ULN2803 chips, Mr. Pascal told me to add a ground to screw-clamp connector J1, wired from the common ground rail in the cabinet. Next i replaced the faulty ones after doing the extra ground wiring and now Everything seems to be ok
