Question

Hi,I recently moved this tv from one house to the next and when I plugged it in, the picture did not come on, but the sound was fine. the stand-by light is continuously blinking but the screen is black? It was cold outside and the tv was outside for awhile, would that have anything to do with it? Please help, would hate to throw it away...
