Any dropped TV needs to be checked over by an engineer. It possibly could have suffered a hairline fracture in the high voltage line output circuits, as the weight of the transformer there tends to focus the force of impact at that point.
You may be lucky. A fracture in low voltage areas of the set is sometimes repairable.
However, a fracture in the high voltage area is not repairable and if confirmed the set should be scrapped for safety.
