Sure does. See the following:
SYMPTOM: Shutdown (into protect) with no symptom shown.
CLUE: Adjustment of Sg2 (master screen on LOT) may resolve but symptom may
return.
POSSIBLE CURE: The LOT (flyback) 5445. Refer to Force for the Service
Code. Several returned samples have been discovered with
unstable/intermittent Sg2 controls. Monitoring the Sg2 voltage may provide
proof of this as the cause of protection.
