Weird Screen Show up when Shut down

"I have the same problem with my Macbook Screen after display replacement. I took my MBP to Apple authorizes nears my home now and let’s see what happens!

Update (06/25/2020)

The Apple authorizer told me it is not because of hardware, it is software issue. I talk with Apple Support advisor USA, he confirmed it is Catalina 10.15.5 bugs and he asked me to wait for the next Catalina updates and We still can use our MBP as usual."

Hey. I ve bought my mbair in mar-20. The same issue persists from the day one. Its not a hardware problem, its an OS issue and Apple has been well informed about it. I was also worried and confused whether to change or not. But except this distorted colour appear for a nano second issue my mbair is running smooth. It occurs only during shutdown.

"Yes, you have a defective part! Time to get it fixed at a real Apple Store if you can. This is not a software issue.

The issue is the T-CON board which is part of the display assembly."
