So the regular protocol, since the Inverter is a fairly inexpensive part (if compared with the more costly, in the $ 140-200 range according to the source for a new part, half the price for a used-refurb unit) implies trying a fresh inverter first, then, if the issue persists, swapping the LCD panel.

2. Changing the LCD panel is tricky, since you"d have to strip bare most of your computer _and_ strip bare the whole LCD assembly, thus removing the bezel, the hinges, the frame with the Airport Antenna and the iSight assembly, and put all together. Tricky, and time consuming, but doable.

3. Changing the CCFL is a nightmarish experience, especially if you lack (like me) expertise (thus I simply asked a tech to replace my LCD and inverter, when that happened to me). You"d have to go through point 1 and 2, peel the reflective foil from the LCD exposing the CCFL being careful to avoid crumpling it, painstankingly desolder a very thin neon light (the CCFL actually, but picture it in your mind as a thin neon. As frail as a real one) and resolder a new one, crossing your finger to do all well, replace the foil and put all together.

Thus, I"d say the inverter replacement is easy but boring and time consuming, the LCD replacement is tricky, but manageable, and the CCFL replacement is for experts only.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

ER-OLEDM032-1Y is the 256x64 yellow pixels OLED display with adaptor board that simplifies your design,diagonal is only 3.2 inch.The controller ic SSD1322, communicates via 6800/8080 8-bit parallel and 3-wire/4-wire serial interface. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.Please refer to below interfacing document for how to switch to different interface. The default interface is 8-bit 8080 parallel.

A wide variety of yellow lcd options are available to you, You can also choose from original manufacturer, odm and agency yellow lcd,As well as from tft, standard, and tn.

yes indeed ! a yellowish colour tint is common in Amoled display, but if found on an lcd panel, then surely it is a display problem... btw how is the find 7a in performance(just curious as i`m gonna buy a new phone so i was considering it as well)..

I just sent it back for Warranty for the yellowing, but they are out of stock until who knows when. They may offer me a refund. Either way, I am going to get an OPO also and sell whichever one I like the least.

I tried to mess around with the manual brightness as you mentioned. And I agree with you. To that it further, the screen shows a more true representation of what you see and what you get the lower you set the brightness. Somehow the yellow of the screen increases more than the other colors the more juice the screen gets.

I find this an annoyance though, but not a deal breaker. Though i would love the have the screen work better in terms of color it is still doable because you can check the color fidelity better through the EVF. So though I compose with the rear screen, if I want to check for color use the EVF.

Mark, thanks for your feedback. I’m sorry to hear that the Color Filters setting doesn’t fix the yellow screen issue. Have you tried to bring your device to an Apple Store and ask for a replacement unit?

I have the same issue. My iPhone 6 (which I am replacing) has a much better display than this new iPhone 12 Pro. The latter has a yellow screen and way less clarity. Such a disappointment,

Agreed!! I’m so upset, especially because even though the staff KNOW this they pretend like it’s all you. I bough an iPhone 12Max Pro, returned it (it was a hassle and cost me $50 restocking fee). Than bought iPhone 11 Pro that was on display and with correct color like my previous phones…when it arrived it’s just as yellow/greenish washed-out as the iPhone 12 was!! So upset, so much money, so much hassle and as a photographer I still don’t have a phone where I can edit mobile posts and know what color they truly are.

Hi guys, sadly I do have the same problem… called apple care and “discretely” after 15 minutes chat, the operator confirmed that lots of cases are arising around the yellow screen. He fixed me a meeting in the closest apple store in town and I went today. At first they have recognised the problem and after several trials they decided to exchange my iphone. Those on display were perfetc and I felt really happy and relieved only until discovering that the new one they gave me had the very same problem!!!

P.S.: iOS 14.2 has just been released. We recommend you to update and let us know if by any chance the yellow screen problem is fixed by this update: https://www.iphonetricks.org/ios-14-2-software-update-10-features-15-fixes/

Just got my iphone 12 today… set it next to my iphone X to do the file transfers and I was shocked at the difference in screen color. I figured it was a setting so i finished the transfer and went through all the display adjustments/corrections stuff… then googled and found this forum. Tried everything… the display is simply not as good as the iphone X i have. Sigh apple. Another reason to never buy the launch!! I’ll be going to At&t to hopefully get it resolved.

“I calibrate my PC colour balance – i am a bit of a nerd. So i can tell everyone this isn’t made up. iPhone has always been a bit over saturated but i accept that. Colour cast however is not acceptable and isn’t the same thing at all. And this isn’t warm vs cool. Yellow is another direction completely. And finally, i spotted this out of the box – never heard it was a thing before and didn’t have to put it side by side to see it, but doing so just confirmed it.”

I am having the same trouble with the screen color. I am replacing an iPhone 7. The screen on the iPhone 12 mini is like sepia, AFTER we adjusted all of the settings to make it white. I have been talking with support for over 2 1/2 hours. They have basically told me to return it and buy a different model. They say they have not seen any issues with screen trouble with this model. I don’t believe them. I am so frustrated.

Marcia, thanks for your feedback. So, the iPhone 12 mini is affected too. Until now we only had reports about the iPhone 12 and 12 Pro yellow screen occurring. It seems that the later released 12 mini and 12 Pro Max can be also affected by the low quality OLED manufacturing standards. We know how frustrating this is. Hope you can get a replacement unit soon, one that doesn’t have the same problem! Keep us updated.

I received my new iPhone 12 Pro Max yesterday and was really disappointed with how yellow the screen was compared to my XS Max. It just felt yellow and dingy.

CornishTD, thank you for confirming that the iPhone 12 Pro Max yellow screen problem is a fact. I’m sure that you would have preferred not to have a reason to write this comment. And yes, we know the feeling. Spending such a big amount of money implies high-quality. But apparently sometimes even Apple fails to meet expectations. I hope that this will be sorted out for you and you’ll get a replacement when stores reopen in the UK. Stay healthy!

Received my iPhone 12 Pro Max on the 13th and mine has the yellow tint as well. Took a picture of it side by side with my iPhone XS and the difference is really obvious. Comparing my 12 Pro Max with my friend’s 12 Pro also showed the difference that my phone has a yellow tint compared to the 12 Pro. It’s so frustrating. Contacted Apple and they are asking me to ship my phone for repair. Was asked to update my phone, restore my phone, all the works but it’s still yellow after all that. Hopefully I get a replacement, one that’s not yellow!

Got my 12 pro max on launch day, soon as I switched it on, I could tell screen was not right, got in contact with apple ( via online chat), sent the guy pictures, he said it was normal lol,

Hi, I received my iPhone 12 mini on the 13th and when I switched it on I immediately noticed the dim, washed out, greenish/yellowish screen. I work with colour calibrated screens as I’m a photographer and the colour cast on the screen is just unacceptable. People’s skin tone on photos are greenish/yellowish. The text on the screen is not black but grey and in darkmode the text is not white but yellowish. It’s really ugly.

With True Tone enabled the screen turns almost to orange. So True Tone is useless too. But that’s less of a problem as I didn’t plan to use True Tone.

And I noticed that while booting up the phone, when you see the Apple logo, that the screen blacks goes from grey to black. This is also visible while watching videos. The blacks are not black but grey for a few seconds and after that they go black. I thought blacks on oled screens were supposed to be black, not grey?

I’m very disappointed. I’m replacing my iPhone 7. But the 7 has a better screen. I did send the mini back today and I’m waiting to receive a new mini, but I’m not having high hopes after reading all the screen problems!

we got two iPhone 12’s and surprisingly one of them has this issue. We could compare both screens side by side and trust me Apple has done a worst job with these displays. Surprisingly Apple service centre was not able to identify the issue till i actually made them compare both the screens. They confirmed that Apple does manufacture diff screens for their devices but are not ready to give it in writing nor they are ready to replace the device. Being an Apple user for ever, i feel terrible that Apple could do this with such expensive devices.

i have same problem with my 12 pro when compared to my iphone x. apparently other iphones have had the yellow tint, especially those who have been sold on release date. wondering if apple can fix the problem with update or is this a hardware problem?

Meysam, thanks for your feedback. Unfortunately, it’s less likely that the iPhone 12 yellow discoloration can be fixed with a software update. It’s most probably caused by low quality OLED panel. I think that Apple will agree to replace this launch-day affected units. Let us know if you visit an Apple Store and get a fix.

I have the same issue. 12 mini arrived today and after setting it up I was surprised my iPhone 6 screen was whiter and brighter! it’s so gutting after waiting 4 years to update my phone . I’ll be contacting apple this evening.

Hi, just going back to iPhone and got a 12 and was really disappointed at the yellow looking screen compared to my oneplus6t and my iPad Pro. Messed about with it all day then found this. It has made a huge difference now it looks proper white again and now makes my oneplus look off.

Same thing it looks really normal now good colors no yellow tinit , changed the photo filter settings and the color tint just raised it slightly and looked good i am sure just an update will fix it
