Power spike may have blown out my 37" magnavox flat screen. Only two years old and my Cox Cable box.. Got the box and tv (my expense naturally) replaced but the next day I tried to play a dvd and the unit only shows that it loads but thats it. Cleaned the player with a cleaning cd and the unit will play cd's and the am/fm function works but after loading a dvd it reads out No Disc. Is my unit also fried ?
