All playfield solenoids dead: quick order of checks
Check the under-playfield fuse, then F4 and its clip on the power supply regulator board, then TP5 for about 43 V (no voltage usually means bridge BR3), then J1 pin 6 for 43 V on the brown wire to the flippers. Voltage at J1 but not at the flipper coils means a wiring break.
