Hoping you did not have electric overload that damaged the power supply, try unplugging the set and push the button On until no lights indicate anything. Then wait about an hour so the capacitors would empty themselves further. Next plug it back in and see if this worked. It is never wrong to push the edges a little in finding if the cables that go around the screen have a problem at that point. When one opens the TV (off power and unplugged) these flat cables should be checked for corrosion and right position in connectors. Corrosion is caused by little moist only, combined with the electricity. Then see if capacitors from the power supply, or any at all, have expanded tops. Those are the larger and smaller towers with metal on top that is divided in three parts. New ones alike can then be ordered but replacing requires basic skills. Further examples can be found on YouTube. Capacitors are common to fail early. Those larger ones have dangerous high voltage and can hold their charge for long span of time. it is not uncommon for devices like this to fail after being off.
