    Hi guys,

    My 2018 Macbook pro is having a rare problem with the screen. The screen is having the purple line or bar horizontally once my cellphone close to it (especially my cellphone on LTE). I went to the apple store last week, and they replaced the screen for me, but the problem remains.

    Thanks

    Tao

    Are you saying that only happens when you have your phone near the screen?

    If it's your cell near it looks like interference. Try turn off your network and put it near your Mac.

    sounds like a cable is not being shielded correctly, i haven't seen a problem like this since CRT monitors back in the early 2000's

    i wager you can sell that laptop for a profit to security conscious individual, since it can act as a bug detector.

    i can imagine some shady drug dealer walking around the hotel room holding the laptop up and gauge if the screen turns purple lol

    I think it is. Because it will get worse while I using LTE.

    Try and put your cell near another monitor or TV and see if it does the same thing.

    sssshhhiiittt, surely they would have shielded the laptop :( I really don't know enough to get around it. Used to just have to move anything away from it which was causing the issue.

    Maybe try another power outlet just incase

    No matter whether I plug in the power or not, the purple line will appear.

    i'm gonna take a wild guess and say is the thin cable between the screen and the logic board that might be causing this, i could be very wrong since i have no heard once a macbook or any other laptop have this ssue.

    Never seen anything like this, either your laptop or your phone must be defective.

    Maybe not holding your phone by the screen?

    What did the Apple "genius" say when you showed them that strange screen, even after the screen had been replaced?

    You must work for Apple Lol

    I hold my laptop about that close to the screen if I text while watching a movie on the couch or doing homework, etc.

    $2000+ laptop and a $1200 phone is a lot of money for it not to work close to each other.

    I would take it to the Apple Store, show them that your phone still causes interference with the screen (even though it is brand new) and politely ask for a brand new one. Tell them you do not believe that the laptop was shielded correctly from the factory. Take your phone up to the MacBook Pro, and Air display units and show them that it (hopefully) does not effect any laptop screen but yours. Once they see that, they should be offering you a brand new MacBook Pro. Hope it gets worked out, keep us updated!

    Good suggestions!

    Sorry for all the friends who wait for the reply. I send it to Apple repair center again last Thursday. And the status shows "your repair is in progress". I'll test it again, and I'll ask for a replacement for the whole unit if the screen still has the problem.
