So one of our kids spilt water all over the top of my closed MacBook Air (2014) model. Didn't know until I went to use but think it happened sometime in the 8 hours prior. Sat in near the heater for a week before trying to power it back on. It works apart from this rainbow coloured line in the middle of the screen. The line was much wider initially but seems to have reduced to the pictured size.
Is it fixable or probably more importantly economical to fix? It was purchased a few years ago in the crazy Kogan deal so it only cost me <$500 but it was still a reliable laptop.
It is used mainly as a family backup laptop but would love to have it working properly again. Any advice?
I would say slim to no chance. Even if you fixed it cheaply, there's a chance it will pop up with the issue again and be unreliable. I would recommend waiting for another crazy Kogan grey import deal (the 12" refurbished deal for ~$900 was amazing), waiting to see if the issue will improve, or plug it into an external monitor and use it that way.
