@marlonmacapagal could be two things. A bad main board or bad panel driver (unlikely). I would check the main board and see if there any obviously damaged components. Some are pretty small so take your time and use some sort of magnifier. Also, check around the heatsink and sometimes it's a good thing to take it off, check things out then replace the thermal paste and reinstall. It will/might help if you post some good pictures of your board with your Question. that way we can see what you see. Adding images to an existing question

After that you could try a tape off. Something like these videos I would suggest that you try a Tape-Off.
