The power surges that lightning usually brings effects the tv from a blown fuse to a damaged board .You need a technician to have it checked. Check all of the inputs to the TV to ensure you still have signal there (you might need to borrow another TV to do this). If the problem is not your signal source, then it's the TV and the news may be bad. If you did not have the TV plugged into a surge protector, the power line problem may have fried something in the TV's power supply. Power supply problems on TVs are easier to repair than many other faults, so an evaluation at a repair center might be worthwhile. Failing that, then you need a new TV. Also try replacing burnt/shorted hi-volt cap C421 470pf/2kv.
