  • Late 2013 macbook pro screen issues

    Just a quick question to see if anybody recognises this.

    We replaced the screen on this machine because there were intermittent stripes appearing. the new screen was not giving image untill we connected it to an external monitor, and then the laptop screen started working again as well. The customer really wanted his machine back, and since i could not show that his screen was not working properly i couldn't really refuse him.

    I suspect he will be back with the same issue, and i am wondering, could this be as simple as the lcd connector on the motherboard being rotten, or is this more a GPU issue? If anything, when he comes back, how do i diagnose a screen that is mostly working?

    Probably a bad LCD panel, but could be any of those things. I wouldn't worry about it, until it comes back to you.

      Replaced the panel or the whole assembly? Could be problems with the EDID ROM in the panel.

        we replaced the whole assembly. If it does come back i'll continue testing. But your suggestion does seem like a contender.
