Story: I have 2 horizontal stripes on my touchscreen, that do not react on touch. The Touchscreen service menu lets me "clean" the touchscreen to show exactly these 2 bars that cannot be touched/touch doesn't react. Hence I decided to change the display (LCD+digitizer, as separating them is to difficult for me)
Now: Phone disassembled to the point, where I can unplug the display on the back, remove it and plug the new one in. Working so far.
Then I try to glue the new display in (display glue tape applied) which means I have to bend the cable a bit to go under the display. Before I push it firmly on the glue I test it again: LCD not working anymore. I see vertical artefacts.
Basically: The boot screen shows the white "SONY" centred on black background. But there are also artefacts from the "SONY" to the top and bottom. Like lines of error pixels with random colors. Not completely solid but visibly exactly where the "SONY" is.
Those lines are not static. They appear where bright objects are and are always top to bottom. Start is similar to this (during run it is not as bad as in the video, for me it is mostly e.g. when the symbols from the launchbar (WIFI, GPS,...) or the battery is shown) https://www.youtube.com/watch?v=O2kBUXdGJtk
This happened to me twice now and I can't figure out, what I could have done wrong. Does anyone knows what happened here and how to avoid it?

OK, my tilt is under a month old and have two concerns regarding the screen. When using the slider, at the very top of the fully opened "motion" the screen ripples in the center as if it is being compressed with a finger. It is about half and inch in diameter and repeats if I slide the screen at the top of its fully opened position. Is this normal? It is visible under my solid blue background.
Secondly, under certain lights there is a rainbow effect when the screen is off. This is only noticeable if I have it under the light at specific angles. If I push my finger on the screen it moves as if the two layers of the touch screen are in constant contact with each other and in turn when I push on it, I can manipulate this location. This is visible under the center most part of the screen. I am using the original screen protector provided by ATT.
Just wondering if this is normal, if not, I'm tempted to return it and get a new one under the 30-day policy.
Thanks in advance!
Anyone please?
Ive never noticed anything like that. It sounds to me that there is some space between a few layers of plastic and that is causing diffraction of light which you see as the rainbow affect. If you have the option of replacing it with a new one I would. I mean if I buy something I want it to be in mint condition when I pay for it, not damaged.
I just got a tilt about a week ago and ive noticed that in the middle of the screen there seems to be a purple greenish tint when put against incandescent light. The size of said glint varies in size but i'm unable to see what changes the size. Not sure if its heat or pressure or something. The touch screen works perfectly its just really annoying to always see such an annoying glint.
An interesting discovery is that when i press all four corners of the screen it disappears and when i press in the middle of the little square it seems to spread out. I feel like theres some kind of material or something in the touch screen that is causing this due to pressure. I keep it in a hard case in my pocket so the screen isnt pressed on inadvertently.
I've searched the forum for any answers but i havent seen anything about it. Any response or help would be greatly appreciated. I'll try to get a picture of it up asap but i left my camera at a friends house and dont know when im getting it back...thanks in advanced

Do you see the same "annoying glint" under neon light (not day / sunlight)?
Lots of NOKIA and SONY ERICSSON phones for example get this screen recolorization under direct sunlight - this has nothing to do with the screen being defective but with the plastic above the screen which breaks the light and shows you this colored spots. If you can't see the same spot under direct neon light then this might be the cause.
It is normal that you get color changes while pressing the screen in. First of, you press / bent the protecting plastic and the liquid within the screen which causes the incoming light to break in a different angle, therefore the color changes. (BTW: you shouldn't do that too often, it can cause permanent stains on your screen!).
There sure is the possibility that your screen gets pressure from underneath due bad assembling! If you're still under warranty, try to get a replacement.
yeah you cant see it in day light. but i feel as though there is constant pressure on the screen between the plastic and liquid since the spot is always there and doesnt really go away (unless of course in daylight).
well im thinking im going to go back for a replacement. thanks for the quick answer!
One of the first things I noticed about the NC was a faint grid of dots under the screen before turning it on. I also see a faint line making up the grid. Im guessing this is "normal" since its part of the screen. I never noticed this on other devices though. I dont notice it when the screen in on though.
I have noticed this too. It shows if you turn off the screen and look at it at an angle under light.
That is the touchscreen sensor, and is there on every capacitive device (whether or not you have noticed before is another thing)..
Does anyone else have this problem:
When you're just pressing a bit harder than the usual touch, on the top and bottom Left side bezel, it causes the Screen to ripple (fluid wave effect).
Not even pushing down too hard, just a firmer press than usual. This is easy too see on a darker background, like the default background when the device wakes up and still in locked mode.
Yes I realize it's a LCD screen, plus this Corning glass is thinner, and we're not always pressing it that hard to notice anyway.
But the Right side bezel and other areas are mostly fine,
So I'm wondering if it's a defect on my device or not (the left side being too sensitive)? would this cause further problem in the future? And it could be a concern if I carry the Nexus 7 in the backpack and other items pressing on it.
Other reports on this:

"the display can give a little and cause the LCD to ripple if you really press hard against the screen"

I wonder if I try the Fix on the other thread, taking off the cover, but instead, loosen the screws a bit on the left side, would that help?
Thanks!
Hi,
My device has this too. Mostly on the left side & a little less on the right side but hardly any on the top or bottom.
While I was watching a video, I noticed a permanent yellow tint on top of my screen (where signal/time/wifi are located, in those spots). The yellow tint is permanent and it's more noticeable when the brightness is on max, especially on white screens), it doesn't go away nor it changes (for example on yellow tint, i can see some past 'time' and notifications). I am not sure how to explain it better. The phone never fell down, nor It has any damages. I have it for a year and I never had any issues.
Anyone with the same problem? I mean it's something terrible but it sometimes it's annoying.
I also wanna say, if I take a screenshot of my screen, and then check that screen on my PC for example, I don't see the yellow tint.
That's exactly how it looks: https://cdn57.androidauthority.net/...17/05/aa-imgur-galaxy-s8-burn-in-1200x675.jpg
Screen burn in, I imagine? Plus I can see my Google keyboard clearly on a fully blue screen. I wonder if the problem is just the screen or the frame underneath the screen as well. I guess it's not fixable unless you replace it...
