First thing to do is sit down and have a cuppa, these things happen.
Flipper problem - Check the fuses on the Fliptronics board and the connectors on that board. More likely a loses connector as each flipper has its own fuse, and all four could not blow at once !
Popping sounds could be the solenoids firing.
Write down the switches on the test report and post here.
Thanks for that, its been a warm day today on the coast,
should have taken your advice and had a cuppa, ended up having a few too many beers instead!!
I will have a look when I'm in a better state!!
