Chosen Solution
I recently got a tv from my wife’s uncle after he said he couldn’t figure out what was wrong. I did the normal tests and it powers on and has the little chime. The screen is backlit but there is no picture.
Next step, would be to use a flashlight and see if you can see any picture, assuming tv is staying on after chime and possibly audio is heard while using the remote arrow keys. Best case scenario its bad led strips.
