Devendra Kumar you will have to cgeck a few things on your TV Be sure the component you are using (Xbox, Cable, SAT, etc.,) is selected appropriately. Make sure you are on the correct input as some TV’s will show a black screen if there is nothing connected to that input. Check to be sure all cables are properly connected to the TV inputs. Unplug all the inputs you have connected to the TV and plug it back in. Unplug the TV for 10 minutes and tehn plug it back in when plugging it back in PRESS AND HOLD THE POWER BUTTON for 10 to 20 seconds which will act as a reset. If none of that worked, unplug your TV and remove the back of your TV. Take a look at the power board. Check for domed or leaking capacitors, loose cables, loose connectors etc. Post some good pictures of all of your boards so we can see what you see. Use this guide Adding images to an existing question for that. You will need a few handtools and a multimeter to work on your TV.
