OK, so I dropped my phone and the LCD went out, I hooked the phone up to the laptop and the phone still works fine, even the touch screen works. ( I used My MObiler to see phone screen on the pc).
I bought a new LCD screen off of Ebay and replace it, now, the LCD screen works, but for some reason, the touch screen stopped working.
When I took the LCD apart from the touch screen, there seem to be a layer of grease of some sort between the touch screen and the LCD. I wiped it off with a lens cloth, don't know if that caused any problem.
Also there is a dark film (tinted) glued to the touch screen when looking from the back, what is that for? I looked at replacement touch screen on Ebay but none of them have the tinted film layer. I've search all over the internet for instructions but can't find any.
So my question is, what are the correct procedures for replacing the LCD screen and the touch screen (digitizer) ? Also after I installed the new LCD screen, the screen is very reflective and the glare is really bad, how do I fix that problem?
Thank you experts!!
You should have replaced both the LCD screen and the Digitizer. There are complete kits on ebay as well as instructions/tools to complete the replacement. Did you purchase the digitizer also?

I went ahead and purchased the digitizer by itself after the original stopped working. Hopefully, it will get my phone back to normal. Thanks for your reply!
in the wiki theres disassebly instructions of the device that should help you (but you probably already know that since you've already switched out the LCD)
In my experience, i have never replaced either the digitizer, or the LCD by themselves, i've always bought LCD+Digitizer and replaced them as one. Seems like the Digitizer is usually glued onto the LCD and i never wanted to mess with that.

I should have ordered the kit instead of just the LCD. What lead me to order just the LCD is when I hooked the phone to my pc and confirmedthe digitizer still worked. And since this is the first time ever I disassemble a phone, I assumed the two things were separated.
But my digitizer should come in tomorrow so I'll just have to wait and see. Thanks for the info.
where did you find a guide to take apart the TP2? I just had the unfortuante luck of smashing mine in the car door as I got in....it fell out of my pocket the exact moment i was closing the door....
My screen is shot, but other than that the device appears to work. I can power on, and try to dial after I press the hard key for the phone pad. The touch portion seems to work, but from your luck, I guess I am looking at having to replace both...
anyhow...any advice on guides and how to find the stuff on the ebay would be apperciated.
I still have 18 months of a 2 yr contract....sucks....and it sucks doubly becuase i just took the insurance off last month....grr..

Here's a photo guide of the disassembly of a Rhodium (TP2), it might give you some insight. There's also been a number of threads in this section about hardware parts and the screen/digitizer in particular, listing places where people found/ordered replacement parts.

The disassembly instructions are here: http://translate.google.co.uk/trans...ka/htc_touch_pro2/&sl=ru&tl=en&hl=en&ie=UTF-8
I did not follow those instructions since I did not want to open the back of the phone.
What i did was I tilted up the phone and used a very small screwdriver and unscrewed the two screws from an angle (it worked).
Then I pried the back of the tilting part of the phone all around to reveal the inside. Be careful not to pull too hard on the flat cable since it's still attached to the back (body) of the phone.
The LCD and touch screen are glued together (I didn't know that before). At this point I would remove the tape that is attaching the flat cable to the back of the LCD, and also lift up the clear yellow tape and detach the three connections.
The widest ribbon is from the LCD, the medium one is for the 4 hard buttons in the front, and the little one is for the touch screen.
I would suggest wearing some sort of anti-static wrist strap (I think I fried my touch screen along with the flat ribbon that is attached to the phone while trying to replace the LCD without anti-static wrist strap).
Once the whole tilting part is freed from the phone, I would carefully push the whole screen (digitizer + lcd) out from the frame, again, they are glued to the frame but can be removed fairly easy.
That's it, the install is reversed of removal and hopefully yours will work again.
Like I said, I think I fried my flat ribbon so after replacing the Digitizer (it came in today), the touch screen still doesn't work, so now I'm looking for that part, I'd appreciate a link to it if anybody knows where to get one.
Oh, and for the parts, just do a search on ebay for "touch pro 2 lcd" or touch pro 2 lcd + digitizer"
Gook luck with your phone!
What tape to use to stick digitizer back to inner bezel/chassis?
Hi - i got as far as trying to replace my Digitizer only to find that the LCD was stuck to it too. So as clever as i am (not) - i tried to remove the LCD off the digitizer - but that just ended up cracking it.
So i'm in the process of ordering a LCD with the digitizer - pre-stuck together (i hope!) - but my question is:
When i removed the digitizer off the front bezel, there was this spongy sort of double sided tape... i assume it was used for a reason and not just any ordinary double sided tape (presumably to allow a bit of leway between the digitizer and the bezel when pressure is applied to the touch screen)...
Any thoughts on what sort of tape this is? - here's some photos of my digitizer and the bezel:
zedii.co.uk/DSC_0002.JPG
^some of that tape is left on the digitizer... it's the black spongy stuff...
zedii.co.uk/DSC_0003.JPG
^i cleaned (removed residue of sticky tape) in the inner part of the bezel where the digitizer would stick...
Any specific tape to use that anyone knows of?

I wish you had asked before you ordered the digitizer + LCD, since I ordered mine separately, and they seem to both working ok. The digitizer does not have to be glued to the LCD. But anyway, I just used plain old Gel superglue to glue the digitizer to the bezel. I used Gel superglue so it won't run into the electronics beneath. Things seems to work just fine now.
One thing to consider when you crack open the whole phone though. Be careful not to loose any part from within the phone, because apparently, I lost something, now my accelerometer doesn't work, and my screen doesn't rotate when you slide out the keyboard. Hope it works out for you!

Thanks for the advice adp9626! Well in summary I think I've just been messing about too much and being stupid really.
In the end, I managed to just remove the top part of the screen without actually having to break into the bottom section of the phone.
I was a bit concerned about the whole sticking of the LCD to the Digitizer part. I actually did purchase them separately, however I was not sure what kind of glue was used to stick them both together - as I recall it was a nightmare to try and remove the LCD off the old Digitizer.
So I returned both separate parts (got a full refund as I didn't use them) - and now I am looking to purchase both parts stuck together.
I'm waiting on the guy on eBay to confirm that they are both stuck together. I'm also thinking of using double sided sticky tape to stick the Digitizer back to the inner bezel...
So that's the final plan! I've been a bit silly in rushing with ordering parts etc. but I just want to be on the safe side now - well - at least with the LCD stuck to the Digitizer part.
I will take your advice on the gel superglue if the double sided sticky tape doesn't prove it's stickyness!
Thanks
Zayd.
Can anyone help me find the lcd screen and digitizer as a single unit for Sprint? Everyone I find states not for CDMA.
Thanks
Anyone ??? I spent an hour on google and still came up with no leads.

I ordered one from this guy and it works great. it comes with the entire top half of the phone and the keyboard. There is only one left so you may want to hurry. Link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=270583335455&Category=20336&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2
Edit: I wanted to add that they're are slightly used so there will be scratches. The one i received is a little more scratched than my original then again the scratches aren't noticeable when the back light is on and you're getting a working screen.
Just my experience, I had a faulty LCD, digitizer was OK. Bought a replacement LCD off ebay, delivered from China but only cost me £20 inc delivery. Arrived with tools as well (T5, T6, philiips, and pry tool). Followed a couple of disassembly instructions online, took me a while to get all apart but managed it. None of the instructions online go through actually taking the screen out, I thought I'd messed it up as I took the back half of the LCD off and left the front bit on, and I couldnt get it off at first. I ended up using a very sharp scalpel to slide between the LCD and digitizer and got them apart eventually, as I didnt realise that they were glued.
Anyway, I just placed the screen on, no glue as there is a ring of sticky tape around the back of the digitizer which holds the screen in. Connected everything back in the end and its working fine. Only prob is I think I damaged the power/standby button, so be careful when around this area.
Touch Screen not responding after replacement
Recently, I replaced a glass screen on a SGH-M919 Galaxy S4. Previously, during the process of cleaning the glue residues off the LCD screen; I rubbed it with rubbing alcohol and it removed a small streak of the adhesive glue off left side of LCD screen and bottom right corner. After installed the new glass screen, I noticed a few spots of the glass screen wasn't sticking onto the sticky layer. So it looked like it has big air bubble between the glass screen and LCD. And I could see the rubbed off streak on the LCD screen. Everything worked fine with the new glass screen, with the exception of seeing the streak and bottom right corner rubbed off.
A few days ago, I had a table clock fell on top of the phone and broke a piece of glass. Nothing happened to the LCD screen and still functional 100%. So I got a replacement glass screen - the same as the first time replacement. With noticing of the rubbed off streak and corner of the adhesive layer on the LCD screen - I decided to rub off all of the adhesive layer from the LCD. I sprayed some Goof Off liquid on the adhesive layer and left it over night. Next morning I continued scraping off the glue with a small plastic card. Cleaned off all glue residues and examined the LCD screen for any scratches or damage. There was none. Re-installed new glass screen - but now the touch screen does not respond to the touching on the icons. Only the Home, Menu & Back touch button work. I was baffled after this.
Could it be that because I left some the Goof Off liquid on top of the LCD screen over night and it might have leaked to the other side and shorted out something? I saw a few forums that suggested a Factory Reset. I did that - but still didn't work. Please advise on what I need to do to fix this problem.
Thank you in advance for the advise or suggestion.
So you know that these are the TP2 forums, and no one has used this thread in the last 3 years....right?
LCD digitizer replacement.. now black screen
I saw the for replacing the LCD-digitizer of my nexus 4 phone, and followed the steps carefully. After I placed the battery, I checked to see if the phone turns ON and the display is working before I complete the last step of putting the back coverplate. I successfully switched it ON, saw a perfectly working screen, and browsed through my apps. To complete the assembly, I put the back cover by gently pressing the frame along the edges, but suddenly I saw some yellow green lines in the middle of the screen. I switched it off and again switched in ON, but now the entire screen had light with no display.
To fix this, I tried again checking all connections but no luck. What could be the reason for the sudden loss of display when it worked perfectly fine moments ago? Is there a possibility that I damaged the LCD while putting the back cover on the phone?
I am also not sure about one of the ribbon connectors of the digitizer. There are 2 big ones which are prominent and has ports to connect. However, there is a little third one which also has to come through the gap but doesn’t connect anywhere. Has anyone also experienced this while replacing the screen? Any help will be appreciated.
I am pretty new here and have loves the source of all things EVO!
I flashed my first rom, broke the screen two days later, and reflashed it to stock so sprint would fix it. They replaced the front half of the phone. The glass, LCD, digitizer, bezel, and buttons. Here is my question: Now when i press firmly on the glass the LCD distorts like a computer monitor. It only happens when I press pretty hard while putting on my 3 layer case as one piece, so I am pressing pretty hard. I know thats probably how I wrecked the first screen, so I've stopped that. However I do not remember the origional screen doing that. Is sprint using lower grade glass screens?? Has anyone else noticed this?
I just bought a used AT&T GSIII described as having been dropped, with the result being that the capacitive buttons don't work. Okay, I thought, I'll buy it, fix it, and I just got a cheap phone. So I brought it home, opened it up, and I can tell right away something funny has happened to this phone. For one thing, there's scotch tape, and for another, there are obvious marks of a dremel having been used.
As best as I can figure, the guy dropped it, screen broke, and he ordered a replacement. The replacement was actually for the international version, which I'm guessing has a different chip arrangement, so the phone doesn't even fit together correctly. In an effort to fix it, he dremeled down the sticky-up parts as best he could, and then figured it was sellable at that point.
Evidence? First, it looks like the sticker with IMEI, etc, has been removed and reapplied. Second, the cutouts in the screen match the disassembly video I watched (British accent, I assume I9300), but the motherboard does not.
Now for questions for our experts out there.
Did I guess right? I9300 screen with I747 body?
The capacitive buttons don't work. Does the I9300 have different touch drivers that would be the source of this problem, or is it likely physical?
Anyone accidently have a I747 screen lying around they want to swap?
Here are some photos of the innards. I'll check back for responses tomorrow. Thanks!
Why not get your $ back and just get a non Frankenstein?
Because I got it cheap, and because it's fun to fix things.
What I'm looking for here is someone else who has taken their phone apart to tell me whether or not the screen side looks wrong. It fits wrong -- those bright shiny parts on the left part is where they dremeled away to try to get the components on the right side to fit.
Also, if there are any kernel/driver experts, what are the difference between the i9300 and the i747? Can I mix and match stuff to get a working ROM?
No hardware hackers here? I see GT-I9300 markings on the screen, but SGH-I747 and SGH-T999 markings on the main board. Can anyone confirm that my screen shouldn't have GT-I9300 markings?
the question is, what did they dremel away, and did they slip and knock some devices off one of the boards? Or did they not dremel off enough, and ended up shorting something else. Or get aluminum or magnesium dust under the BGA chips there, shorting pins that shouldn't be?
I'm all for cheap, but IDK, if I even spent $20 on it, I'd be raising cain with the seller to get my money back. there's no guarantee they didn't hose up the main board or the display in the process of trying to merge the two.
Now if you had one of each, the intl and US versions, and were able to confirm each piece worked properly on its own, I guess you could part it out.
Good comments, and those are obviously some of the risks that are present with this phone. It works fine right now -- I'm testing it out as my daily driver. With the navigation bar turned on, it works just like a Galaxy Nexus.
So obviously nothing is shorted out or vitally missing right now. Could something be jostled free or get fried later? Possibly, but any phone you get could go bad for no apparently reason. So far it seems like a good buy, though I do wonder about resellability.
The dremelled parts are all just metal protrusions that (I guess) are supposed to allow for the ICs on the board. Since the board arrangement doesn't match the protrusions, it wouldn't go together at all without cutting away some of the metal. I've actually done even more now (careful to protect the actual circuitry of course) so that it actually closes all the way. Also, the main board should be totally fine, because all dremelling and stuff have been done on the screen half of the phone. Unfortunately, the screen is the expensive half ...
Hey there oblib,
I think that the guy didn't just buy a new screen then, he probably also bought the housing for the i9300. That would be the problem here as the housing is completely different from the US side variants, thus requiring the dremel job. I think that the screen should still be fine, despite being for the i9300, but I'm not sure. Looking to buy a screen right now and I can't find any information on whether or not the screens will work (don't know if the US variants have some small differences to account for the revised chipsets).
Just in case, can i ask you a favor? Can you check if :
1. the screen works with the i747 innards? (reading on sites that they are possibly interchangable)
and
2. if where the flex cable is matches the position of where the i747 flex cable should be?
I'm pretty sure that they are the same because of the pictures and comparing, but i just want to double check =] couldnt hurt to be safe
As for your problem, not too sure about fixing the capacitive buttons, but you could always check the connection between the cables. As for repairing and fixing the poor dremel job, you can always get a i747 compatible housing. Here are a few:
http://www.ebay.com/itm/Blue-Origin...112?pt=LH_DefaultDomain_0&hash=item3a78dec370
http://www.globaldirectparts.com/Samsung-Galaxy-S-III-SGH-I747-Front-Housing-p/smsng6115910.htm
I couldn't find any instructions for separating the housing from the screen. As fas as I could tell, it's glued together, isn't it? Because that was my first thought when I bought it -- just fix the connector.
Could you verify that your screen does NOT have GT-I9300 printed on the flex cable from the screen to the connector? At least I think that's where I saw it. If yours doesn't and mine does, then yes, everything fits just fine.
Until I find some instructions on separating the housing from the screen, I'm going to keep on assuming that the problem with the capacitive buttons is due to the differences in international and AT&T screens, because I would doubt that this housing has been separated from this screen, so how would any physical damage happen to the capacitive buttons?
It would be good for you if I figure this out, because if it is software and not hardware you'll have the same problem.
So I looked at your links, and that's exactly right. My front housing definitely does not look like those products. But the question still remains, how do you non-destructively separate the house and the screen? All that blue adhesion looks like a mess. Here's the global direct adhesive, by the way: http://www.globaldirectparts.com/Samsung-Galaxy-S-III-Housing-Adhesive-p/smsng6115915.htm
Edit:
Looking closer at the picture I posted in the OP, the printed "GT-I9300" is on the ribbon cable just above the battery compartment. That would indicate that the replaced the entire front assembly, cables at all...
For future record here's a side-by-side of the different housings. I believe that the right is an international body (with carvings to make it look like a I747), and the left is from a SGH-T999. They are obviously different.
From what I have read in this thread, the housings are different for all the different models of the SGH-XXXX.
Additionally, it doesn't look like it's as simple as mix'n matching the parts together to make a functioning Samsung Galaxy S3.
Does anyone have a reliable online source where someone could order front screen assemblies (the i747m / Canadian version)?
This thread has been very informative thus far. I have subscribed and will keep up with this thread. Great catches.
i9300 compatible with T747?
Looks like the i9300 screen combo isnt compatible with t747 right? I wonder if i can buy a i9300 replacement screen+digitilizer , and install on my I747 Frame? would that be possible?
Per this thread, NO.
Recently I had an issue with my i747 motherboard.
As i747 motherboard was not available, my local repair guy put i9300 motherboard and housing in my i747 body.
I am using that cell now. Nothing feels different. No hardware or software issue.
I have an i747 motherboard. Im working on fitting it to i9300 lcd housing . Everything works except the camera .
hi i have too an issue with my t999 motherborad can i put the i9300 in the t999 housing without problem !!!
I had my note 4 screen assembly replaced after I dropped it. However, the screen is no longer completely secured in the phone. The screen pushes into the frame if I place pressure on the screen and I can get my finger under the edge of the assembly on the top left corner. The home button is also loose, but gets tight like it should be if I hold the screen down. This is an annoying issue and I've recently noticed that dust is getting inside the phone, which I'm worried will cause hardware damage. The front camera is already blurry and cloudy from dust getting inside. If I take the screen off and apply new adhesive, will the screen sit in the frame like it should or is it impossible to restore the feel on a phone with a screen replacement to what it was like from the factory? I hope you hear from you guys, and thanks in advance.
I would take it to a local Sprint service and repair location (or where ever you got your screen replacement). They should be able to reseat your screen in the housing and clean your camera right up. In terms of applying new adhesive, you shouldn't really need to. The 15 some odd screws on the back should take care of it. Source: I'm a S&R Technician
Thanks for the help! My problem is that I'm hesitant to return to the shop where I got the screen replaced, because when they originally replaced it I was unsatisfied with how it fit so I went back and had them do some more work. It was alright at first, but it began to get steadily worse in a fairly short amount of time. So I'm a little cautious of going back there to ask them to do more work. If I asked them to reseat the screen assembly, do you think it would help? Also, is it possible to return to an almost-factory feel with a replaced screen or do I need to accept that the assembly will never be quite as tight as it originally was?
Similar issue
I had a similar issue and I took it back to sprint which they fixed regardless of my device being rooted.
Did you have the screen replaced before you took it to sprint, or was the screen loose from the factory?
you can find the replace guide at ifixit, I don't leave the link,you can google it.
If you want to buy original LCD screen ,you can go to the HCQS.
i have tab s4 t835.
accidentally tab slipped from hand and hit floor from about 2 or 2.5 feet height. nothing happens but there is grey whitish blurred area created on glass shown on picture attached. s pen ..touch image all working good on it.. as screen turn ON this greyish area almost non visible.
can someone help me what is this and how i remove this from screen or glass..?
This looks like you damaged the lcd screen when you dropped it. I don't think it is anything you can "remove" short of replacing the screen. Which, for Samsung, is usually pricy.
but the screen works good at that portion even s pen works fine..
That doesn't mean that liquid crystal matrix under the glass isn't damaged. The display has multiple layers, and you can damage one without breaking the others. The problem with Samsung is that they laminate the layers in such a way that you really have to replace the entire front assembly to fix a broken screen. This looks like a damaged lcd to me. There is probably a screen repair shop near you that could evaluate it.
u r right ... i must get it check from repair shop or samsung and see what tthey say... but im also thinking now i will use it as it is as it didnt cause any hinderance to me
That's the thing about damaged screens. You usually can still use them fine. With Samsung, I'm guessing the repair will be in the $300 rang. Which is 50% of a new device. And probably 100% of the current eBay identicle unit replacement cost. It is crazy how quickly the value drops out of these tablets. After two years and the emergence of the Tab S3 and Tab S4, trade-in eBay sale value for my Tab S2 dropped from $650 to $120.
Let me know if the techs that look at your tab agree with me. If I'm wrong, I'll buy you a beer next time you're in Lubbock.
Joe
yep,
Looks like damage to one of the inner layers in the screen sandwich. Fortunately along the edge and not in the middle of the screen. It could just be 2 layers pulled apart because of the hit, but I don't know of any way to repair aside from a complete screen replacement.
Does that part of the screen still light up, or are there dead pixels?
