The key issue seems to be the screen looks overly dull and green and greatly lacking in brightness. At first thought I felt it might be a damaged back-light but when I adjusted the brightness setting it goes from barely visible to impossible to see (in low-light conditions). I also noticed the brightness will vary during use but always in a shade of green.
Now I feel like a silly goose, it doesn't have a backlight which means it could only be the AMOLED screen or the connectors on the board to the screen.
my bet will be on the connectors because if the water damage got the screen either it will not light up at al or the damage won't be uniform depending on the parts that got water
but since the damage is uniform and is related only to colors (missing red and blue) 90% it will be the connector, so you're best shot is to locate the connector and try to dry it more
note that i have no idea how hard this is
good luck
Cheers I'll give it ago I guess I've got nothing to loose.

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!
Recently, I noticed the is a strange circle in the middle of the screen. When the screen backlight is off, it appears as a black circle. When the screen backlight is on, it appears as red/yellow/black ring. Somtimes it went away by itself, and other time I have to "wipe" it away with finger force.
Anyone know what is wrong?
2 questions
1) Have you tried removing the screen protection just to see whether its on the screen protection or on the main lcd screen
2) did you ever exposed lcd it to high electromagnetic waves??
1. I didn't remove the screen protector as I believe it's beneath the LCD film.
2. I don't think it has been exposed to any electromagnetic waves, as it appears after I pulled it out from my pocket.
I've had it too but it's gone now
I had the exact same problem a few weeks ago. The place I stayed was not well ventilated and I THINK it caused some water condensation to occur between the digitizer and lcd screen. I slept in an air-conditioned room the next day and it was gone!
My deduction is that you need a cool or cold environment for the stain to evaporate.
The same problem arises again, and this time it has been a couple days but it still did not go away.
It looks almost like a burn mark.
You may have a defective digitizer.
Found another thread talking about this:

This is the so-called 'Newton ring' in optics/Physics. It means that in that area, the thickness of LCD is slightly thicker/thinner than rest of the area. This is normally due to stress at that point. It is annoying but if there are no repeated color rings, like red/yellow/blue/red/yellow/blue, it should be fine. If you have alot of repeated color rings, the LCD may approach its life end.

Thanks for the info. When you said it should be fine, do you mean it will disappear, or it just won't affect usability?
It may disappear if the stress is released, e.g., you push the area a bit or you put it into different temperature environment. But I doubt it will disappear for ever. It was not there in the first place then it came. This means some sort of stress/pressure built up there. It should not affect your daily use a lot. It is just a visual effect. But if it gets worse, the colour rings will become very dense and sharp. It will affect you visual. I had a phone pinged on LCD sometime ago. It had similar rings like yours. But it was so dense I could not see any thing behind it. I had to change it for £35.
Also I looked at another previous comment about the humidity. It could give you the same effect. Maybe you can bake your phone a bit?
My Captivate's screen has suddenly gotten much darker than usual. Even at low brightness, the image quality used to be really good and the screen was really sharp. Now, for some reason, it seems to have gotten noticeably darker and duller. Aside from that, the whites seem to be tinted blue. I know this is an existing issue with the Super-AMOLED's so I'm not too worried -- I'm thinking it was probably always tinted and I'm only noticing it now that I'm really looking. The last thing I noticed about the display is a set of odd marks behind the screen; oval-shaped markings slightly to the right of center running from top to bottom and left to right. Anyone know what these are?
Assuming you haven't flashed a kernel with the brightness fix, color fix, etc. you can get the phone exchanged through warranty for display problems. One of ours developed an issue with the tint and clarity and we had it replaced no problem.
I have a D5803 that came back from being serviced. The touchscreen went bad, so the whole assembly (screen + sensor) was replaced.
Since you have to almost completely disassembly the phone to get to the screen, I suspect something went wrong during the repair.
The screen is flickering at random. By flickering, imagine a bad fluorescent lamp: you can clearly see the brightness varying vary fast, causing a flicker effect. Also, imagina a CRT screen. The flicker stops when you refresh the screen, like cycling through the home screens of your phone.
The guy who repaired it said it is a bad resistor that controls the current going to the panel's backlight. His excuse is that the board is very thin and fragile and that something might happened during the repair service. He also said that if he tries to do something else, the problem might get worse/something else might break. I suspect the screen installed is not OEM and is of bad quality. Sometimes the screen keeps autopressing as if someone was actually touching the screen, but not. Wiping the screen down on soft clothes (cleaning it) solves the problem. The screen probably doesn't have an oleophobic coating.
So, my question is: Is this guy right or is he lying (trying to push me ****ty parts/service)? How to know?
Also, is it possible to have a slightly smaller sized screen part? Because it feels that the screen area has decreased a bit (bezel increased somewhat). But since I do not use this phone since almost two years ago, I might be imagining things.
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?
