@appleguru Ugh, that's so unfortunate. :-( I wonder if they have to tear down the entire dash again to re-align it?

@appleguru that is so frustrating! And my understanding is that the whole dash has to be ripped apart and trim pieces removed (and potentially damaged) in order to replace the screen/MCU. I'm guessing they would have to do the same thing to fix the poor alignment at the top? In another thread someone said that it's probably not the screen that's crooked, but rather the dash trim piece above the screen isn't pushed down enough or something? Are you planning to take it back for this?

My Dec 2016 P100D just started the yellow burn. Laptops have this from the backlight (or heat) damaging the display, so it is a manufacturing flaw.

Thanks for posting... I just noticed on my 10/16 MS build today. Will be calling SC tomorrow.

Just got my car back and the touchscreen works intermittently. It spazzes as if something is always touching the screen and after a few minutes the touchscreen becomes completely unresponsive. Then I have to do a reboot and it works for a few minutes until it goes crazy again. Really wish I would’ve just dealt with the yellow boarders. Car is going back tomorrow. I think they’re going to replace the entire MCU this time.

That's frustrating. Hopefully the issue will be resolved after your next appointment.
So, I took my S to the SC last Tuesday.
The MCU was replaced, without question, with the repair completed in 3 days (I had a couple other items worked on during the same visit).
The invoice says, "Replaced the media control unit (MCU) and verified proper fitment and secure".
The yellow ring, of course, is gone, plus I think the touchscreen performance seems a bit snappier. If the new MCU has a faster CPU and/or RAM, that might account for it. Alternately, does anybody know where the modem is? -- built into the MCU? Perhaps the network connection is faster.

Could be the start of it. Mine just appeared obvious one day but I can't say when it started.
We've joined the yellow border group. 3/2017 delivery. Here's a photo of the top of the screen. It does extend down both sides. The bottom border is black so not visible there. I thought I was starting to notice the yellow after reading this thread when the thread was started but seemed very faint; today very noticeable when we were out of park and in Nav screen during daylight. Call placed to service.

Wow. That's way worse than mine. I think I caught mine early after reading about it here. Replaced last week. New one is good so far.
Good to know that happened to you....Not THAT it happened to you
. Ours goes in Friday and at least we'll be prepared for whatever happens. Hope we don't loose settings, especially the seat positions. Got it just right and don't want to try to reset.Good to know that happened to you....Not THAT it happened to you
Only settings I lost when they replaced my MCU were paired Bluetooth devices. Everything else was retained.
Update: since getting the center screen replaced 2 weeks ago, I noticed today that it is uncomfortably hot to touch more so on the right edge of the screen (been driving on the highway for 44 min). It’s 47 deg outside and inside temp set to 75. No direct sunlight on the screen. I don’t remember ever having this issue since I got the car a year ago even in the hot sunny summer days.

Yup just noticed that earlier today. Got my car back yesterday after it was with Tesla for 2 weeks (long story) and I felt that the top right was very hot. Hopefully its a non-issue because I really dont want to give my car back to Tesla Service, ever again.
