Apple we have a new problem! T-CON logic failure!
@craiglloyd - I don’t know if you’ve been watching the Answers section we’ve had a large up tick on MacBook Pro 13” Fn & 15” Touch Bar systems with failing displays.
Note the top & Bottom edges build up these over & under scans black and gray bars. Basically, the timing logic in the T-CON boards is drifting from heat damage! At first I had thought the issue was people where blocking the vents which would also cook things
So far the issue is mostly seen in the 2016 & 2017 models. The only thing that makes a difference between both of these is their heat sinks and its placement. The 13” Fn model has a single fan Vs the 13” Touch bar which has a dual fan design both have intergraded graphics. Yet the Touch Bar model doesn’t have an issue! Then if we look at the 15” Touch Bar systems they have a the same basic two fan design with a discreet GPU and it also failing. Heat build up is the only thing different between them: Too small a cooling system or too much heat for the cooling system!
So effective cooling is the variable I see here! The displays are functionally the same across the two 13” models, and the designs are likewise very close to each other than the single vs dual fin design on the heat sinks!

13” Touch Bar logic board:
15” Touch Bar logic board:
So what I hope you can write something up on this as this is a serious design flaw in Apples newer systems which sadly has taken a bit of time to come to the surface.
The only solution I can offer is replacing the display assembly and I’m sure in a few more years of time the problem will come back! a grand a pop!
Is this a good question?
Apple should then replace all of these macbooks by touchbar models for free
