digitalindiairitty let us know exactly what is going on with your TV. You said the power is ok, so let us know how you know this. You also want to let us know if you have sound. See if you can get your menu display to show, just not a TV picture. If so then start by shining a flashlight beam at an angle against the screen at a channel where you have sound. See if you can make out any shapes silhouettes etc. As you can see we need more information from you before we can really help you further.
