![]() ![]() There is hardly any air circulation in the T-CON board compartment, making it extremely vulnerable to damage from overheating. It is mounted very close to the heatsink radiator. 2016 onwards, this board, while still being connected to the display, sits inside the top case or main chassis (read: keyboard panel). It was part of the “lid”, removed from the main chassis. Up until 2015 this board used to be tucked inside the hinge cover at the bottom edge of the display. All MacBook displays have a small logic board of their own. Poor thermal management leads to the display logic board (T-CON board) getting cooked from overheating. It is believed to be a design flaw from Apple. There is a technical explanation for this. However, in our experience here at Fixxo, the 13 inch MacBook Pro non Touch Bar model 2016-17 (Model A1708) is the most frequently impacted model. MacBooks with Apple M1 chips are considered safe. These include 13 inch, 15 inch, even 16 inch devices. Technically, all MacBook Pro models launched after 2016, with an Intel CPU chip inside, would be vulnerable to this issue. Read about it here: Flexgate: MacBook Pro display backlight issue - Is it repairable? Which MacBooks are impacted? Although both impact the same MacBook models, that issue is actually entirely different. Note: Is your MacBook display showing Stage Light Effect - alternatively bright & dim areas along the bottom of the display? Or is it going blank when you open the lid beyond a certain angle? If yes, it is not a T-CON board issue. ![]() In the worst case scenario, the entire screen is covered with lines rendering the device unusable. In early stages, it may be completely reversible. This of course depends on how far damaged it is.
