I have a LP133WQ2(SJ)(A1) A1502 2015 MacBook Pro 13.3" Display Assembly. I have never heard of, or seen this issue before. I purchased an entire MacBook Pro (Retina, 13-inch, Early 2015), to use the parts off of. I purchased the exact same computer, but with the eBay listing saying the Mac was slow, so I thought most likely it just needed to be wiped out. This was not the case. I got the computer, and noticed how slow it ran, and the OS had already recently been wiped. So I took the display off so I could install it on my customers computer. Once installed, my customers computer crawled all the way from booting up, and in to the OS. I isolated the problem by using only the LVDS cable plugged in. As soon as I unplugged the LVDS cable and used an external monitor, the computer ran fast again. I tested this by doing the same with the Mac that I purchased, and got the exact same result. I did try using another LVDS cable I had in stock, but I must not have the right LVDS cable I am assuming as I read somewhere the 2015's are different. For the life of me, I cannot figure out why a screen connected via the LVDS cable would make a computer run slow? Can anyone shed some light on this? The LVDS cable the computer came with, is NOT damaged, is don't see any nicks anywhere either.
