My MacBook has these weird horizontal lines!?
The MacBook also makes a high-frequency ringing. Any ideas on what is wrong and if I can repair would be great!

Did you have a liquid spill or sit the the system down on a wet surface?

I went ahead and switched the housing, ... so i replaced the display cable, and it stayed so then i switched to a new mac screen half, and connected that stuff and it works. Still want to know how to fix it properly.

To be clear you replaced the display assembly - Right?

negative-- I replaced the display connecter cable (from the logic board to the thing which i do not know the name). Still playing around with it to figure it out.
