Pink and Green streaking on LCD. LCD panel replacement fixed it.
Original LCD panel was failing. Displaying green and pink streaking all over which was especially visible on window "chrome" or other white or gray areas. I ordered the panel and some tools from Ifixit and had my repair-savvy friend have a go with replacing the faulty LCD.
Went well. The heat gun operation did misshape the plastic "edge gasket" material a bit in a few small areas. Otherwise a perfect replacement process.
Be very gradual with the heat application and very patient with lifting the glass up. We used some small bits cut from a plastic bottle as wedges to keep the glass from resealing to the tape. I had bought replacement double sided tape from eBay but ended up not needing it. Finally be REALLY CAREFUL with the surface mount connectors when you remove them. The audio one messed up when releasing and a pin had to be re-soldered. They are really delicate.
