@lprince

this sounds like your backlight failing. Check your power board for any obviously damaged components. When the screen turns dark, shine a flashlight at an angle against the screen. See if you can still make out any silhouettes etc. If so it’s your backlight. If not then there is the possibility this is either main or power board related. You will have to let us know what exact model your TV is. Once you remove the back from your TV post some good pictures of your boards with your question. That way we can see what you see. 在已经存在的问题里加入图片

Hi @lprince,

Try doing this to see if you get a picture:

  1. Hold the Volume Down and Menu buttons
  2. While holding them, press the Power button then release the Power button only
  3. Wait five seconds then release of the Volume Down and Menu buttons
  4. Wait for approximately 30 seconds

Do you get a picture?
