Getting it done Tuesday. Wife going to be mad when I tell her we can't take car to drive-in movie because of not having AM. Any solutions?
I've been in 3 MCU1 cars that had the yellow border issue so I don't think the yellow border is specific to MCU2...I forgot to add --
MCU1:
some (large?) fraction of older screens will eventually start to leak some strange clear conductive goo and develop bubbles in the main screen. The goo can harm the electronics under the screen in the center console and the bubbles are unsightly.MCU2:
some (large?) fraction of screens will develop a "yellow border" that will permanently turn some part of your screen yellow. Tesla or adventurous owners have a tanning lamp rig that will use UV light to reduce/eliminate the yellowing, though that appears to be a temporary fix.Both issues are likely related to high cabin temperatures.

based off my sampling, it was around the timeframe of AP2.0 and the 75kWh intro onwards that the screens started exhibiting that behavior.I have seen it on later MCU1 screens also. I wonder when Tesla made the change?

MCU2 cars weren't built until March 2018.So if you had the yellow border does that mean you have a MCU2 car? Looking for an easy way to tell. 90D MS Sept 2017 build
The easiest way to tell with modern firmware is to go to your software updates tab and look at the hardware configuration. It says whether it's Nvidia Tegra (old) or Intel Atom (new)So if you had the yellow border does that mean you have a MCU2 car? Looking for an easy way to tell. 90D MS Sept 2017 build

Right -- I should have been more precise -- if you have MCU1 you may or may not get the yellow bands (and would know by now if you're going to get them) -- if you have MCU2 you are much more likely to get yellow bands. And if you upgrade from MCU1 to MCU2 you are now prone to getting yellow bands.
The UV treatment fixes them, but I haven't heard one way or another if it is permanent or not.
Disagree, there were two different screens used with MCU1. The first screen was the one with the bubbling issue. The second generation screen was the one with the yellow border issue. At some point later on, Tesla went to a third screen which supposedly will NOT get the yellow border. That third screen has been installed in new MCU2 cars (but possibly not all of them) and retrofitted to some MCU1 cars as a replacement (some done under warranty, some paid for by owners). You have to look at the part numbers to tell. Any MCU1 car that upgrades to a new MCU2 will get the new screen which (to date) does not have reports of the yellow border issue. Your statement that MCU2 = Yellow Border problem is simply not true.
MCU2 cars weren't built until March 2018.
I don't think the fair comparison is 4 year old MCU1 vs brand-new MCU2
Your choices are:
- "Factory fresh" (or refurbished?) MCU1 with under-speced memory chip
- get a 4 year warranty
- done by dealership so you maybe get a loaner and absolutely get a cup of coffee
- probably going to fail again in 3-8 years (even without bonkers logging, lots of other things write to flash)
- no features gained or lost
- $1800ish (?)
- It's MCU1+new swissbit memory chip
- tremendously inconvenient
- no features gained or lost (ie keep AM/FM/XM and youtube still won't do anything)
- Probably will last the lifetime of the car
- reputed to make the MCU operate faster/more reliably
- warranty probably applies only to the chip, and will be a PITA if you need it
- $400ish (?)
- MCU2
- 4 year warranty
- you get fancy new features and lose AM/FM/XM radio
- much faster
- unknown reliability, likely better than MCU1 but worse than MCU1+swissbit
- Future proof(ish)
- $2500
