Hello

I have recently purchased #The shadow - it is an awesome pin tbh. But I have several problems with I cannot solve.

1. Switch from wall target is not working. I have exchanged it to a new one (as well as the diode) and nothing. Switch tests doesnt recognize switch activity. Both coils from wall target are working flawlessly in solenoid test but during gameplay wall target is not dropping (if I put if manualy up) or rising - therefore magnet is not working as well.
2. Optos on the battlefield are not working - i have exchanged transmitter and nothing has changed - it is not visible with cellphone camera (remaining optos are visible of course). Therefore kicker is not working BUT also yellow target which is near the entrance of the battlefield, is not going up or down (the same - in solenoid test it is working ok) - and when the ball drops into the ball popper which should launch the ball to battle field - nothing happens... after some time machine starts to look for a missing ball and then it launches it to the battlefield (but kicker is not working due to bad optos)
3. Left ramp entrance optos - they were working and suddenly no activity and error in test report.

I have checked all the switches - I got three errors - kicker, optos on bf, wall target switch.
Please help I ran out of ideas how to solve this
