Despite the television being off, if there was an electrical current that overcharged the fuse that it was joined to, it may still have overloaded the television's circuitry. While it is possible to fix the most common possible problem oneself (a melted fusing of a wire attaching the tube to the main circuit) it is highly recommended that the television be brought to a licensed repair shop.
