Half of my tv screen is flickering, we have tried numerous options such as powering tv on/off and checking the cables but still the same issue.

Nim 09 … need more info. If it is your picture thats flickering, it could be the tcon board or the panel starting to fail. if it is just the brightness, it could be the leds. Please give a better description, better yet, upload a picture or video of what you see. Adding images to an existing question
