Its the flipper relay
I rang pinball spare parts earlier and they dont have any in stock or couldnt suggest where to get one
I just finished rebuilding the whole playfield, all new coils etc , played 3 games ad then heard the buzzing from the relay and now no flippers
Are you positive its the relay?
Have you removed the driver board and tested the relay with a battery to see if it pulls in?
Just thought I would mention it as normally these are the last part to go, and it might be a cheap 7408 or 7402 chip.
