DIY UV Treatment for Yellowed MCU Screen
- Thread starter ucmndd

No, the screen doesn't need to be on.
Under bright light or the UV light, I can see the outline of adhesive but during normal driving, I don't notice it unlike the yellow which was very noticible.
UCMNDD, this has been a great DIY for those of us that live a bit away from our SC and don't wish to loose the day or two of work to drive the cars to the SC. As people here already said the light has to be really close and for me the LEDs needed to be directly in front of the area I'm treating. My first time doing it I placed it just in the middle of the screen and the Yellowing faded (darkened) for the most part. Then I began to work the outer edge in sections. It only takes me about 5 mins to set it up and then I forget about it for the day.

I still have a few darker areas but a couple of more times of me moving the light around will put it like new. In the areas I was focused on from the beginning I see no yellowing or dark areas.

I'd recommend you bring it in to a service center (if you can) and see if they will fix it with their UV treatment before going for a replacement.
Here is my attempt. I removed the screen and put it in a box, had 2 lights on in for about 28 hours. No specific reason for time, it was just when I put it in and took it out. All the yellowing is gone. Ring remains when uv shines on it. Also I tried using the UV light on a non yellow screen and also see the uv glowing ring....
The 2015 pre-refresh screens have a different issue where they develop bubbles and leak goo from the bottom.
I've also seen a leaking and yellowing screen....
Nice thanks for the insight. I have yet to deal with this issue as most the Tesla’s I own or owned never had many miles before I sold them. But it’s been something I’ve kind of been waiting to occur with my P85D now that I actually use it and has 28k miles. I will def remember this for when the time comes.
Thx
BulldogsRus, perhaps others meant that, but the poster I responded to said, "It’s hard to believe Tesla is taking so long to “create and produce a machine” when a $35 diy solution works just fine". That seems pretty clear he wasn't aware the tool actually existed. If not, it was poorly written.
You also have to put it in the context of the poster having sold his Tesla, still remaining on a Tesla forum, and doesn't seem to appreciate that not all owners detest their Teslas. Yes, there's much to criticize about how Tesla goes about their business, but there's still quite a bit to appreciate about owning a Tesla.
Very true, I can criticize a lot of things about Tesla’s and don’t hesitate too cause it’s informative for others who have never owned to get honest insight since so many owners won’t say anything negative like they owe it to Tesla. Which is the last thing any owners should think or feel if they really knew the shady things Tesla has done in the past, present and definitely moving forward. I always try to tell people who are new to owning how much better Tesla was years ago with their customer service. It was top notch and a step above anyone else and has drastically changed primarily due to less employees. The service has never been an employee issue too me but more of an upper management issue leaving employees to take the fault for something they can’t control. With all the positives definitely comes with a lot of negatives especially when it comes to trust. I don’t trust Tesla at all (the ones making the decisions, such as the updates they have done to negatively effect cars). But from my experience the employees on the floor are still some of the most respectful and generous people to deal with. At least at all the service centers I’ve been too.
Tesla did my screen earlier this week. They told me they had version 3 of the UV light treatment. They said version 1 took forever to fix the yellow border, so they developed version 2 that had a more powerful light source. However, they indicated that the UV light source would burn out after several treatments. The new, version 3 unit seems to be reliable and normally treats the screen in 2-1/2 hours, with an occasional need for a second treatment if the screen is really bad. Version 3 of the device is being manufactured and shipped to all the service centers now.
I asked whether the treatment is permanent and they replied that the fix is too new to know for sure, but that no screen treated to date has come back for a re-treatment. They also said that if a screen needs a re-treatment it would be at no cost as long as the car is under warranty. He did not say what would happen (ie, if you would have to pay for the treatment) if the car is no longer under warranty.

im not sure if it was overkill, I've fixed 2 screens with 2 lights for 24 hours about 6-8" away. Tried 1 screen for 12 hours and it did not fully fix, but didnt have another 12 hours.
