@naalii that sounds like a main board issue. You need to try all different inputs and see if that changes anything. You also want to check if your on-screen menu still shows. Let us know what you get with that. Ultimately you need to take a look at the boards on the inside of your TV. Unplug it, remove the back and take a look. See if you can identify some obvious damage like leaking or domed looking capacitors etc. Take some pictures of your boards and post those with your question so we can see what you see. Use this guide [guide|21499|commentid=417084] for that.
