Hi everyone.  I have had a problem with my macbook pro late 2011 and managed to get rid of the problem following advice on this thread.. the motherboard was replaced a few years ago by apple for free ( even after the warranty had expired)  but recently i started to get these annoying red or pink  lines on the screen where white should be.

looking for an easy way out and to save money i downloaded gamma control and so far everything is good.

once you download  and install it  all you have to do is adjust the “ white point luminance “ until the red lines disappear. In my case it was around   0.97    you can try it for free before purchasing but the price is relatively low so this seems to be the best option for me . good luck with yours..
