when i came in and turned of my tv nothing happened no picture, the green power light came on so what do i need to do to fix it.
This is a little vague. Is it properly connected and receiving a signal? Do other TV's in the house work? Do you have a DVD or VCR you can check to see if it plays on the TV? Does it smell funny or make any type of noise? What type of TV is it? How old is it? Try to unplug it for a half hour. Provide more info please.
