Hi I have a l32wd12 r a TV and it will not turn on

If the clock is on then the unit is receiving power; maybe the external input feature (which tells the TV which outside source to display on the screen, e.g. cable TV, DVD player, VCR player, etc.) is not set to display the TV channels. On my Sony TV there is a button that displays TV setting options (e.g., Favorites, TV List, External inputs and settings). The external inputs function displays the options as video 1, video 2, etc., right up to video 6. My video 3 is for the VCR, video 4 is for the DVD, and video 5 is for the cable TV channels. If the TV is set for say video 3 and nothing is playing on the VCR, the screen will be dark (almost as though the TV is off). Your solution might be as simple as choosing the right external (video) input for the TV to receive the channel signals.
