It happened to me that the TC fell on the sidewalk face down, so I had to find and replace the screen. Couldn't find any pictorial guide so I decided to share my experience for the benefit of others with the same problem.
Cause: Cell phone shocked, fell down, hit
Symptoms: touch screen works OK, but display has cracks, blackened areas, which are spreading as time goes by.
Screen type : TC combines the matrix sensor (touch) and the LCD in 2 layers, the front touch-glass and shell, and the LCD itself underneath it.
Source of display: I bought via eBay on this source: Asia Bol
http://stores.ebay.com/newasiabol
Cost $70 inc. shipping and arrived within a week and a half. Rumors insists the at below $100 a screen is either factory dropout or refurbished.
Tools needed: Torx screwdriver T5-50, the size can be viewed after removing battery door, at lower corner.
A flat sharp tool ("fish knife") to help open the plastic case, but not too sharp to scratch the phone.
Here are the pictures and some notes:
1. Remove battery case and battery, SIM
2. Remove 2 screws from lower side
3. Prick open the shell with the flat tool
4. Prick open the top shell with the flat tool
5. CAREFUL as there are 2 tiny ribbons from the touch screen/hardware buttons into the PCB, one is held in place with sticky band (keys), the other (digitizer) is locked in-place with a lever, tiny one! - pull them out, not before noticing where they went into and lifting the lever on the smaller one.
6. Take apart the FRONT shell with the flat tool slowly as not to tear ribbons
7. Pull the LCD ribbon out
8. Carefully pull the old screen as it is held in place with sticky gum
9. Clean interior glass of phone if needed, pull out new screen protective sheet and put in place.
10. Connect new screen ribbon, 2 keyboard/jog tiny ribbons
11. Press shells in place
12. Pray you didn't forget anything and load SIM and battery
13. Good luck

Excelent work....!!!
Awesome man
Great contribution! You give me hope for the next generation of xda'ers!
Thank you!
Excellent work! Must be added to Polaris wiki page (if it hasn't yet!)
my lcd screen crashed 1 month ago. replaced a new screen for 450 CNY included the handwork fee.
great job.... thanks for sharing
My TC has got a big scratch on the screen (cheers to Jack, my cat who is responsible for that )...
I just ordered a new LCD screen, and by "mistake" i only ordered the digitizer...
Now after reading this post, it seems that I accidentaly did the right thing, since is only the front panel which is scratched and not the LCD itself... Am I correct?
Anyway do i have to disassemble the whole phone to get the front panel out???
As you see on the completly dismanteled TC picture above (left on the last picts row), there are:
Glass top, actually the outer top shell, and the LCD & Digitizer are one piece (the 'glassy' square with flat orange attachement)
If the scratch in on the shell glass, that's not the LCD screen, it is the so called "LCD LENS GLASS" or "faceplate".
If the TC fell and you see cracks and smears on the screen instead of what should be displayed, that's the LCD.
Please make sure where your scratches are.

Thanks for the Info,you ve been very helpful .... Well my scratch is on the outside and I couldnt find any outside faceplate for my TC... Instead I ordered the digitizer (see picture attached) which for me it seemed as the right option (I did that before reading your post )... Now I will just have to wait and see when it comes, if i did the right thing........ I will let you know
well, I was (and still) confused as I was looking for some info about the screen assembly, and the only one I've found was on this lab site (not particular to TC model though).
Please read the paragraph in RED starting with "ATTENTION..." later on that page (the link above includes Google's translation from russian).
More confusing is that the part you mention here IS available as is...
puzzle solved.
I was curious so I dismantled the TC again, than I notice the the glass shell IS carrying a tiny ribbon, which means IT IS the digitizer (I though it's coming from the hardware keys).
So I assume you ordered the right part.

cheers... I feel ever so glad!!! ... but you would recon I would have to go through all the procedure to get it out and install the new one?
Actually it's a very delicate work with a steady hand and non scratching behaviour.
points to notice:
- The side silver bars are detached by sliding as well as pulling gently, as there are L shaped pins coming out of them into a niche in the body.
- The glass digitizer ribbon is run from one side of the main board into the other, so unlocking it (small lever and pull out) is needed as well as having the upper and rear shell apart as much as allowed, Or having the LCD wide ribbon out (& digitizer small one) and let the 2 shells free for easy access.
Saying that, it means that the procedure is almost identical as for replacing the LCD as the glass/digitizer is attached to front glass with sticky rubber and you need to get in there to release the tiny ribbon.
In your case I assume you also have to pull the bottom hardware keys' plate (assembly), in order to release it from the old shell/glass.
If that is the case, be carefull as the assembly is pinched into place by fragile plastic bumps that keep it in tight place in order to make a good push action (click). You'll have to widen the shell sides a bit and help it out.
! bent ribbon, and some mulfunction may occure.
Awesome Guide, Reuvenm you're the MAN!
I'd been searching all over for this guide so as to attempt to remove both the front and back camera. My Company just implemented this silly policy that doesn't allow phone w camera
Reuvenm, by any chance that you've had a good look at both the front and back camera and if it's a type which can be un-plug easily? Pls do not bother to disassemble the TC again, really. Just wanna check cos you may have shot some other pics of your disassembled gem that may show the front and back cameras
Anyway, great job and thanks a bunch in advance
you can disable the camera by software & registry, but I guess they want it to be out of sight..
as you see on the left pict on the first row of images, the front camera is a cubic aparatuse with 3-wings circle in the middle, just underneath the ext GPS antena hole:
this can be pulled out but I think it's ribbon (connection flat wires) is going via a cooling metal plate element and then to a PCB connector. Not sure about that as it's very delicate in there.
as for the back camera, I can't recall
here is a close up:
Hi Reuvenm, thanks for the really quick reply. Yeah i wanna get them removed altogether. So I took a leap of faith and viola! I had gotten the Back camera (3M pixel cam) out!
Followed the steps as you had illustrated and yes the 3M pixel camera was attached using some kind of L-shape flat metallic ribbon cable that ends up w a PCB connector. Wasn't difficult to remove though. I'll try to disassemble the Front camera tomorrow when i've got the time cos got to catch up on some work now.
A really big THANK YOU to Reuvenm for posting this amazing guide and i'll get some shots of the Front Cam removal and post them back here again.
Outstanding work man
You really got the guts gotta say
Elegantly done and explained!! I copied this guide with pics for future reference
This opens the door for a whole new era I guess, right guys!?
glass deformation
Hello gusy
Can you give me a suggestion ?
One day i noticed this "stain" on my screen when the device is off.
At first i thought it was liquid traped insinde the lcd (as seen on other phones) but it turned out not to be.
This stain is visible only in bright neon light (at my workplace), and it moves or dissapears almost completly when i press the screen.
Outside, or in normal light the sceen has no problem.
I think that the top glass part of the screen is to big and it bends a little causing this.
Can i remove the top layer of glass, cutt let's say a half of milimiter from the side, and stick it back on ? or is there someting holding it under ?
I noticed that in a corner i could peal it off, but i don;t want to take any chances to breack something.
thanks in advance
Hi. My HTC Inspire had a cracked screen so I bought a digitizer replacement, and the disassemble/install/reassemble seemed to go ok. But after doing so I turn on the phone, it makes the little vibrate as it starts and then the screen comes on but as a low glow and doesn't go past that. Don't know if the phone is booting all the way or not, just see the glowing screen.
Did I screw something up or is there something I can do to get past that?
I've done a soft boot, the battery was removed for an hour while I was replacing the screen, the SIM card is firmly set, etc.
Thanks for any help!
Well, the phone was sitting here "on" (still only with light glow) and I heard text messages coming over and the little green light is now flashing so the phone is up and running apparently, the screen just isn't showing. But it's has the light glow, is it possible the new screen isn't all the way set in place even though it has the "glow"?
Thanks!

Sounds like the screen is getting power but one of the wires is not put back completely. Made be you reversed the wires when you reattached them
Thanks a bunch for the reply. When attaching the glass to the LDC there's the little thin ribbon that inserts into the little white plastic clip, and then the wider ribbon part that slides up the side slot and snaps into place on the other side. Besides those two, would there be other wires I should look at? Those two look nice and secure.
Thanks again!

I have not taken mine apart yet but I walked a buddy threw it over the phone. Are you sure the cables are plugged into the right connectors? I think he also mention 2 plug in plugs that needed to be attached as well. What I would personally do. Is take it back apart and make sure everything is cool. Making sure the ribbons are not pinched or messed up and making sure all connectors are connected firmly.
Yes everything is plugged into the correct place, actually only fit in specific areas. I've just finished taken the phone apart for the 5th time and the ribbons are all flat, not kinks, seated fully, etc. I'm starting to wonder if the screen I got is faulty. I'll keep piddling with it.
Thanks.
Allright. Ever since the last time i've taken out the battery of my Sensation, i've been slightly annoyed.
I've noticed that a small bulge developed in the battery compartment. I've also noticed there are a couple of streaks/scratches.
Why the hell is the battery compartment so susceptible to scratches? Also, should this bulge be of concern? I can even feel it if i run my finger over it.
Is the battery compartment back side actually a black film? You know, where the disposal symbol, and the FCC logo are.
If so, that would explain it, sort of...
not sure if serious. i really wouldn't worry about that, fella.
Oh, i'm serious. It's been bothering me. And i wanna know if the compartment is made of a film of some sort, or if it's plastic.

I think he meant that the scratches won't be serious.

Regardless, anyone know what the battery compartment is made of? Not the surrounding area, but the back of where the battery sits. Just as i had described before.
Does ANYONE know?
And can you get a replacement for that part?
It's the same type of metal that is on the exterior of the casing. You can buy a new battery back door housing if you'd like. They go for about $10-20 on ebay or amazon.
MMmmmm... No.
That's not what i'm talking about.
The place where the battery is fitted.
Right there. The spot with the largers amount of surface area in the battery compartment.
There's a disposal symbol on it.
I've got a little bulge there, and some scratches.
It feels soft.
What is it?

It's made of aluminium, the little silver grounding pin is part of it, it has a square shape, and that aluminium part is connected to the lcd back by other sort of 4 pins. I opened mine to try to clean the dust under my screen, then i realized i needed a heat gun and glue, so i left it like that. The pins that make contact with the lcd may be another possible cause of the touch problem...
Do you want a pic?

No no. Ok. You take the back cover of the phone OFF. And you take the battery OUT. The area behind/around the battery. It's black. It feels softer than any other part of the phone. THAT is what i'm talking about.
I ran my nail along it, and it left a mark... . And i kinda feel bad about it. Although it's inside... and the rest of the phone is in perfect condition.
That's the area on the phone i'm talking about.

This we overlooked while troubleshooting touchscreen problem.
Thanks
Ahem... eerrrmmm. Is anyone NOT clear of which part of the phone i'm talking about?
Are you talking about the black sticker in the batter compartment? I believe its just a plastic sticker. The bulge is probably either air that got trapped or a bump in the aluminum casing beneath. Either way the bulge and the scratches are purely cosmetic. There is no "replacement" for each sticker has several unique numbers on it. Also why would you even care?
Anyone have a guide or tips on replacing the motherboard. My tablet bricked while updating to 10.6.1.8 and is stuck in the Asus splash screen. I've seen to utube vid on the screen replacement but can not seem to find a motherboard how to. It seems to motherboard must be removed during the screen replacement. Will I need paste? Is the large copper heat sink cover glued on? Any advise would be great.

The copper pad has glue where the processor and the rams are. Some might have glue at the far left and right side. But you can lift it off (you will break the warranty seal in the process). If you're replacing the motherboard, you need to:
A. Disconnect (1) the battery (connector located underneath the copper pad); (2) charging cable (flat amber); (3) touchscreen cable (flat white or silver, sometimes covered with black tape); (4) lcd screen cable (strand of multi-colored wires taped down to the battery); (5) remove the small amber cable connecting the power switch to the MB; and (6) disconnect the speakers connector from the MB.
B. Remove all the tiny screws in plain sight holding the MB to the magnesium frame.
C. Lift the cameras off their slots with something non-metal, like a toothpick.
D. Lift the MB just a bit to make sure it's loose, then SLIDE it out to the left, paying particular attention to the power button module (small amber ribbon assembly at the top right corner). If you pull it straight up, you will rip it.
Reassembly is just the reverse. Be sure to connect the battery last, just before reinstalling the copper pad. Good luck. Go to this thread for pics.
Thanks for the pointers. Will I need any thermal paste for the processor?

Apparently, the copper pad is smeared with some heat-conducting adhesive at contact points with the processor and ram chips. Some people would just stick it back. It didn't hold as well the second time though, in my experience. I cleaned off the sticky stuff, used Arctic Silver 5 on both components, and stuck some copper tape around the pad's edge. Just personal preferences.

i don't think it is necessary...
so there are 2 cables I am not able to disconnect. one is the larger longer cooper ribbon that connects to the charging\docking port. the other has a similar connection. it is under black tape and is between the mico hdmi output and a multi color ribbon. I was able to get the other ones disconnected. Please help. Trying to take my time but I am getting frustrated and worried I am going to break something
EDIT- I figured it out. The black part behind the tan connection part is tinny but flips up. I got it disconnected. That was easier than I though!
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?
Pictures
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.
(located a few mm in front of the ribbon cable that connects to the lcd assembly.)

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.
