Bad CCFL bulb(s) (or connection(s)). Swap for test bulbs or use test jig to drive bulbs in yours. OR Bad HV Transformer(s) (or connections). Ohm out various windings. Compare same winding on one transformer to another. OR Bad driver(s) for HV Transformer(s). OR Feedback/Sensing circuitry for CCFL bulb balance correctly (or incorrectly) functioning. OR Enable (from Scaler board) starts out active, but cuts out. DVM OR B-Plus starts out present, but for some reason leaves. DVM Edit: Even though not bulged, could still have a defective capacitor in/on power supply/inverter. ------------------------- Location: Far, Far Away
