With a multimeter verify if you have power in inverter, if not, try to connect the inverter to another power supply for testing.

I replaced the CCFL bulb, switched the unit on and it turned off after 5 seconds

If you have not changed the inverter that was actually best to try first as it is easier. So change the inverter or try a spare.

good luck
