if the big transformer is exploded then replacing it should work.
disconnect the transformer from the circuit. connect two 12v bulbs
( or LED in series with 1k resistor ) with one end of each bulb
connected to the center tap wire and other to end terminals.turn on
the circuit and if the bulbs glow then the circuit is ok.

these days transistors are not used in the output stage of inverters.
MOSFET or IGBT are used.
