Hello my name is***** am sorry you have encountered this kind of problem. Sadly there is no reset it sounds like from your description you may have gotten a small surge to the TV.
Usually when this happens there are swelled capacitors on the main power board which could easily be repaired they would just need to be replaced and it would mean there would be some soldering work needed as well to replace the faulty capacitors.
