Hi,
I bought an used phone and it has some black spots on the screen , no dead pixel only some part darker then others.
Can you tell me if it is possible to fix it ?
Do I need a new lcd screen ?
Is it possible to change it withput specialt solder?
Thank you
Andrea
Sounds more like the Digitizer some times you can gently massage the black spots out to the edge of the screen.You dont need any solder to replace there attached by a ribbon cable.But beware taking your phone apart is not for the faint hearted.
Thank you very much for your answer. I'll try to do as you suggest me!
To make a long story short, my wife dropped her Samsung Galaxy S3 i535 phone a couple weeks ago and shattered the front glass. I ordered the replacement glass on eBay and proceeded to get it installed this past week.
One of the things I noticed was that none of the repair videos adequately documented how to route and attach the button for the home keys at the bottom of the screen. I was finally able to get the old home button ribbon cable detached from the phone and pulled free from its location. I noticed that there was still quite a bit of adhesive left on the resting location for the home key pc board (located a few mm in front of the ribbon cable that connects to the lcd assembly.)
I made the mistake of thinking that the adhesive consisted of some form of double sided tape, so using a small blade and a pair of forceps I began removing the adhesive. Turns out, the adhesive was attached to a felt-like material that was covering the back of the LCD. Once removed, I noticed that the section of the screen from which the felt had been removed was slightly discolored.
I proceeded to reassemble the phone with the new glass, and it is working correctly, with one exception:
The entire screen (not just the area where the felt was removed) appears to have a greenish tint to it. This is most notable when booting the phone. The SAMSUNG logo appears as almost a neon green (My wife assures me this should be white) and the booting animation is mostly green (She assures me it was multicolored)
A couple of questions here:
Did the piece of material I removed from the back of the LCD cause this problem, or should I be looking at something else for a solution?
Is there any chance this felt-like material contained the backlighting for the LCD Screen?
If not, could just a small section of missing felt allow enough light to escape to discolor the entire screen?
Also, since I obviously can't replace the felt, would coating the expose area with some form of paint or something work to restore the proper coloring to the phone?
I am currently looking at other replacement lcd assemblies which, from what I can tell, simply involve moving the motherboard from the old phone into the new assembly, connecting it, then putting the back cover onto the phone. If I can afford spending the $100-150 that these cost, I would like to avoid it. If this is my only suitable solution at this time, I would like a definitive answer so that I can make the purchase and get her phone back to working order.
Thank You all for taking the time to read my post, I can post pictures later to elaborate on what I am describing, but my wife and I are both at work at the moment and I don't currently have her phone to take a photo of.
Pictures would be nice. However your back light shouldn't discolor your screen. My guess is you loosed a cable or something else causing the screen to discolor.

I will get pictures posted this afternoon. After taking a little more time to look at it earlier today, it appears that Green and Blue colors are working, I just haven't got any red.
Do you know where to find a diagram of what ribbon connectors control what aspect of the phone?

A little late, but here are the pictures of my wife's Galaxy S III (i535)

that will give you an idea of the connector for the screen. you say all you did was replace the glass? not the whole screen? I cant imagine how this would happen unless you damaged the ribbon cable when removing the glass.
unless you want to remove the glass again you'll have to take it apart from the rear, which isn't too hard really. take the back cover off, then remove all the little screws you see. that piece of plastic will come off and this is what you'll get: http://imgur.com/WwoOgMP
the red box is the connector, make sure it's seated. i'm not sure you can get all the way to the digitizer panel from the rear, but this is simple enough it's worth trying before removing the glass again.
also there are plenty of youtube videos on how to teardown the sgs3.
on a side note, task killers are bad for your phone.... use Greenify instead, or nothing at all.

If this ribbon cable that connects to the LCD was damaged, it might be your problem.
In that case, you will need another LCD.
It's best to buy the LCD and Glass as one piece.
About $120 or more.

Hi guys,
I'll bring this zombie topic back to life
So have any of you changed the lcd screen themselves?
How many connectors are there on the screen assembly?
I can clearly see just one in the middle of the phone next to the battery.
When I connect the new screen and turn on the phone - the vibro squeaks as in normal boot, but the screen doesn't light up.
My first guess was that I got a faulty screen so now I'm checking the second one and it does the same...
Is there anything I'm missing?
Thanks!
Hi guys,
I have a Dasaita PX5 unit with Android 8.0 and 4 GB RAM.
I've bought it a few months ago and it was working fine until today the screen just went crazy.
The screen will start touching itself all over and enabling settings, or quitting my GPS software, or activating apps, or flipping through different screens etc.
I've tried to update the system software, update the MCU, and even a factory reset. The crazy screen issue still persist.
Any idea how and why my screen went crazy and how do I resolve it?
Thanks
Here is a short sample of what I meant by going crazy:

I know exactly why and have had the same problem. There is a ribbon cable that comes out of the screen between the glass and LCD for the digitizer, its damaged the screens are so cheaply made the glass is still somewhat sharp and the cable kinks and breaks. . I actually just came on here to post if anyone knew where I could get a replacement besides Aliexpress.....
You should try reconnecting the ribbon cable, else just get yourself a screen replacement from where you bought the headunit.
I had similar issue where bottom part of the touch screen no longer register touches and as time goes by, the whole screen is completely "untouchable".
The root cause is that the ribbon between the unit and the screen panel connect to the mainboard is rubbing against the unit casing's sharp edges causes permanent damage. Fortunately, it is still under warranty and i have got a replacement panel, smoothed the casing edges and place some duct tape before replacing the panel.

I just tried it and it got worst. :S
Someone with the answer?
My laptop charger fell on the phone screen which was facing up on my disk and damaged the film screen protector on the display, but after removing the screen protector the display was fine with no cracks or color changes ,my question is will the phone display get any color changes with time or if the display is fine now it will remain ok
thinking positively. it will be/is ok
