- Turn off your TV and disconnect the cable connected to the power port.
- Wait for a couple of minutes.
- Plug the cable back into the power source and try using your TV again.
- It would be best to keep other cables disconnected from your TV when you remove the power source.
If this does not help you, move on to the following solution.
Every bit of information fed to the TV through the input cables is what it displays to the end user. Since most of us use set-top boxes or similar devices for content streaming, we need to ensure that the cable connecting the external device and the TV is not damaged. You should thoroughly check the wires for any visible physical damage and try using a different line from the one you have used.
You could go to your nearest electrical store to purchase replacement cables and check whether that helps.
If none of this solves your no-display/picture problem, move on to the following solution.
Check your T-Con cable and main board:
Check the back of your TV. If you see lights on the back end side of the TV, but you do not see anything at the front, the chances are that the problem is with the T-Con cable or the main board.
So get the replacement part for your TV’s model from any authorized store and bring it to someone with the technical expertise to open and replace these parts of your TV.
You should try the following fix if this does not help your case.
Backlight failure:
Get a flashlight close to your TV screen and carefully notice whether you see anything on your screen. If you know the content you should see appropriately under normal conditions, the problem is with the LEDs.
It would be best to take your TV to a repair expert and inform them about your issue with the LEDs of the TV not working. They should be able to replace the faulty parts for you.
If this does not help you, move on to the final solution mentioned below.
