Title:

Use a cooling fan as a temporary solution to the T-CON issue

Text:

Hello there, community.

I’ve got to the conclusion that the issue of having horizontal lines on my macbook is related to the flexgate/T-CON heating.

When I am working in a cool environment, with below 20 deg Celsius, I have no horizontal lines on the screen, even for hours and hours of usage.

Although when I am in a hotter environment, over 24 deg C, the lines start showing up on the bottom-end of the screen after about 30min of usage, when the peaks of high temperatures start to occur and keep up for more than one minute, around 80~90 deg Celsius.

The lines start building up from the bottom, with a kind of a strong white line at bottom-border of the viewport. Above this crooked line, some pink horizontal lines slowly start building up with a width somewhere about 5mm.

I am thinking about using a cooler pad in order to see if the macbook will not present the issue on an ambient temperature (tropical country, around 25 deg C).

'''Question 1:''' Has anyone heard of a successful case of managing to keep the macbook cool enough to prevent the appearance of the lines, acting as a temporarily solution, while we hope that the recall comes sometime soon?

'''Question 2:''' Another important question is, even keeping my macbook cool all the time, is there any guarantees that the issue will not continue to build up? The increasing damage, spreading these lines more and more throughout the screen, is related to the opening and closing mechanism, wrecking that cable, or is the heat the issue?

'''Question 3:''' If I close the lid of the macbook and connect an external monitor, keyboard and mouse, Could it prevent the display getting more damaged? I personally guess that it would not help as the macbook would still heat up (if I do not use a cooler, or some other solution) and things would get worse, but I would really appreciate your comments on this as well.

As I said above, so far, the lines only appear if I am in a warmer environment. But I wonder what would be the root cause: the movement of opening and closing the lid, stretching the cable + the heat, or just the heat itself.
