Screen with Stain, can't fix - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

My device started last week with a stain in the screen that I can´t fix, has anybody have this happened?
It´s a yellowish mark on the top left side of the phone, haven't droped it or smashed it, or anything other than regular use, does anybody know?
Attached is an image of the mark.

My Z3 did that - then the screen started peeling off! Repaired under warranty

Broken Screen or?

About a month ago I got my Kaiser screen replaced as it was broken, now all of a sudden the screen is all whitish and I can hardly ready whats on it!
Is the screen broken again??
I'm fixing to replace the screen in a Kaiser i bought used with a broken screen. From the reading i've done, it sounds like one of the cables to the screen is loose. Trying pressing on the middle of your keyboard and see if anything happens. The big ribbon cable has a connector there.
hmmmm coming to think of it when I pressed the middle of the screen it used to do some funny effect (like when you press your TFT monitor) but now nothing happens!
Is your screen something like this?

last night i was woken up by a text, i looked at my phone and all of a sudden the screen went crazy. Started scrolling up and down (like a bad signal/wrong format ntsc/pal on a tv). Everything got all messed up and lines and dashes all over, kinda like your screen, it started acting wierder when i began applying pressure on the top of the device by the earpiece and d-pad. So i soft-reset the device and it was still doing it while boot up, leading me to believe it wasn't a software issue.
So in my half awake state i just left it on my nightstand. I woke up and its perfectly fine now, even when i press all around the screen.. wierd huh?
I didn't notice anything like you descriped, touch screen and everything else worked like before. Only the colors were like on the picture. Tried hard reseting but didn't help. Phone is still under warranty so sent it to be repaired, i can post what they did when i get it back.
Thanks jrask. Thats exactly how it looks.
I think i have some bad news for you, the screen was damaged and needed to be replaced. I think it was cracked under the frame.

Xperia X1 Black screen

Hello, you are the owner of Xperia X1 and some days I see a black screen. It happened after I opened and then closed the track and suddenly the colors and pixels began to disappear until the screen became black.
I opened the phone, I got the ribbon flex and everything seems fine. No broken or cracked (not even). Once I touch the screen appears black work but now I noticed that not do anything you give him the finger.
From what could be the problem? After what I read were others with this problem but we found no concrete solution.The phone is no longer under warranty.
Excuse any grammatical errors but I am in Craiova, Romania.
No one help me? please!
why is the blue screen? The phone works, can speak on it but not see nothing...
The flex band is the problem?

Screen Fades to black

Hello,
I have seen other issues here about screens fading to black, I have the same issue bu the difference is when i press on the back cover of the phone or shake it the screen works well, but after half a minute or so it fades to black starting from the outer border inwards, this happened after I dropped it on the carpet of a very low height as i was sitting on the floor at the time and it fell of my hand. Could it be something loose? Some maintenance center (Not HtC specific) told me I need a new screen but I don't know if that makes sense,
I am just troubleshooting before I start dis-assembly

Bright marks on Display

Hi fellow Sony-Fans
Recently i noticed several bright marks on my Display. First i thought it was just fingerprints or grease etc. So i removed the screen protector. But them marks where still there. Its pretty subtle but it's visible especially on a white background. It bothers me extremely. The support was no help at (ofc...). When i tilted the phone i noticed that those marks where actually the edges of a much bigger and round mark in the middle of the screen. I guess the heat of the battery somehow affected the screen. I can't upload a picture bc a network error occurs. But even if it's hardly to see. What can i do? I was always careful with the device. It was in a mumbi case and i had a screen protector on it to save it from drops. I bought the phone in March 2018. Shouldn't the warranty check this? (i live in Austria btw). Please show me a solution, it drives me crazy.
I have the same things since april 2018. I bought the first lot of the xz1 company (pre order).
Unfortunetly just a screen replacement will solve this.
This is also the reason I want night/black mode in my phone so much.
These are pressure marks - basically you need to swap display to get rid of them. They happen when the phone is in pocket and for some reason there is pressure - you fall, you sit, whatever. I've had it happen with Sony phones. During warranty period they have swapped the display.

Half white screen, touch responds when i can get the screen to stay on, what happened

I take extremely good care of my phone and one day, this thin white line horizontally ran across the screen. It bothered me but all the touch functions and screen sensitivity were in tact so I left it for a few days. When I would turn it on the bottom half of the screen would be white but I could get it to go away by touching the top half and I could touch anything under the white block too. But now I can't even do that, it does some weird flash and won't let me look at my phone at all. When the white line appeared at first I did a factory reset etc. But it didn't help. I don't know what happened to it, the screen doesn't have one crack or scratch either. So my question is what the heck is wrong with it? and if I were to replace what is wrong what would that be (screen, lcd, touch digitizer) or something I didn't list? please help!!
