My tv keeps going off too but where is the

The switch you were talking about is not on every Akai only some of them have a power switch on the back panel, People in the forums are not what I would call "experts" many of them are just regular people who tried something and it worked. The issue with your TV is not a simple on / off switch, it is related to bad capacitors on the power pack and the more you use it with bad capacitors the more damage will occure to the video processing board.
