Chosen Solution
I have a Macbook Pro 2015 13-inch with water stuck in the glass panel, but the screen itself works normally. It seems the glass panel has to be broken to be lift off of the LCD. I think the replacement parts on eBay are for earlier than 2013 Macbook Pro Retina Can I find a front glass replacement part for the retina model? EDIT:
Yes you can just replace the LCD panel on Retina models (a lot of people say it is not possible, however it is, just fairly difficult). We do them all the time in the UK, the glass and LCD are stuck together on this model. Your problem would be with the backlight sheets however; liquid has hit the bottom layer of the backlight sheet and stained it, which usually causes diagonal bright streaks or specks. The LCD panel itself hasn’t got liquid in between it (it is completely sealed), may have a bit of liquid on the back of it, but the issue will definitely be the sheets. The sheets can’t really be cleaned unfortunately, so the whole lid needs to be replaced. You can buy new backlight sheets, but you have to removed the old screen without cracking it (pretty difficult) and the new sheets are usually dirty, since there is no easy way to handle them.
I think my comrades here are giving you false hope. Yes you can land a rover on Mars, but doing it successfully takes resources I don’t have. IMHO trying to repair this for the even experienced technician is not something I want to tackle. It’s a waste of time and money. After you try it and spend the money on parts (trying to find them should tell you how little they are in demand), you’ll probably just end up buying a complete unit.
Glass only on this model is absolutely impossible, I haven’t seen anyone done it successfully. Glass+LCD is possible but that makes much less economical sense, since the LCD is a significant part of the cost. If you got the backlight sheets or clamshell damaged, you might just as well toss the whole thing away.
Its possible but very difficult. You have a high chance of damaging your lcd screen. You could try removing it and putting it in a large sack of rice to try and suck the moisture out. If you want to do that follow this guide. MacBook Pro 13" Retina Display Early 2015 Display Assembly Replacement
Rice may we’ll be a valid solution for things completely unrelated to electronics but nobody in this industry would take such a suggestion seriously! All it does, especially in phones or Macs, is give the liquid more time to do more damage while the ill-informed and deluded wait for a miracle!
