Usually these inverter pairs are master and slave with a ribbon between, as far as I know both need to be working to control the dim function and ensure even lighting. With both hooked  up and the circuit complete the error sensing circuit will be operational and upon trying to fire up the tubes will kick out if theres a fault. Try the usual on these buggers, dry joints on the transformer and HT joints and the transformers going open. Failing that give me the numbers and i'll look see if I have the ones your lookin for cheap cheap...
