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.
Hey guys,
I tried replacing my DINC digitizer again and everything went smooth until I booted the phone up. The middle of the touch screen doesnt work very well. I checked the cable to see if it was loose multiple times but that didn't work.
So I took the whole thing apart again and looked at it closely and realized the Krazy glue I applied was applied on the side roughly where the problem lies....
Is it possible it is messing with it so that it is detecting a touch there or something? I used krazy glue on there because I thought it would be like plastic.
Or is this just impossible and the digitizer I ordered is defective? It works besides the middle section of the screen.
on the contrary superglue is insulative which could also be the issue since the digitizer needs to be grounded not sure what it is like under the digitizer but is the area it gets glued to kinda metallic if so that could be your issue if not then it could be a bad digitizer i dont think i would have not used superglue i would have used double stick tape or something like that... or hell with how my case i have on mine is designed i would not have used any adhesive just left my case to hold it onto my phone incase it ever got broke again...
Hmm, ah so perhaps it is just not allowing that part of the screen to be sensed.
In any case, I replaced my "new" digitizer with the old one that is slightly cracked for now. I used krazy glue and it worked perfect this time, but then again i was careful with the application.
I will clean off the "new" and try one more time, but I suspect now that the "old" is working so good that it was in fact a defective one.
sorry to thread jack, but since there is discussion already started, I have an slcd dinc, can I directly swap the amoled screen into it? Would you guys happen to know?

it will not work. the board requires different drivers and i think a different power output. (i could be wrong) but its like if you bought a plasma tv and swapped for an lcd panel.
kind of figured that. thanks makes sense.
I've searched and I can't find anyone else that has the same screen issue as me (they may have but without a picture I can't be certain).
Anyway, I was pulling stuff out of my gym locker yesterday and something knocked my Evo out. Of course it fell flat on the bench, thus causing the screen to become damaged. However, my "cracked" screen doesn't look like any of the other cracked screens I've seen online. My front piece of glass (the part your finger actually touches) remains intact and in great condition (I know I can still unlock the screen because I can feel the haptic feedback of the capacitive buttons), but it's like the screen behind it is what's actually damaged.
Is that correct? And what part would I need to order to replace it. Thanks
I believe that its the lcd
yep thats the lcd itself
Yep, sounds like your digitizer is ok, but your lcd is borked.
Thanks everyone. Will probably be picking up an EVO 3D, then selling my OG after I fix it.
I recently bought a galaxy s3 off ebay that just needed a glass screen repair. Having done several of these with other models I thought no biggie ill ju st change out the digitizer and have a heck of a deal lol until I started looking into how the phone was made and the screens being fused together like they are. I followed a youtube video and heated the screen with a hairdryer and proceeded to try and carefully tried to remove the outer glass without harming the digitizer or lcd screens fused behind it. Unfortunately when I removed the glass screen the digitizer came with it. I thought id ripped the digitizer's flex cable til I read this phones digitizer doesnt connect that way. It didnt crack the lcd screen in any way tho, so Im pretty sure I can just clean the lcd rly well and make sure all the adhesive and glass is cleaned off and use new 3m adhesive to install a new digitizer then the glass screen over it.
The only thing im questionable about is a thin brown ribbon/wire that was pulled out of its original place iand tore a little while doimg this removal. Some of the adhesive from the factory apparently stuck to it while I was heating the glass and attatched itself to the digitizer somewhat or enough to work its way out and initially tear as I was pulling the glass off. Its not the buttons or the small cable that attatches them but it is right beside them. Can anyone with some experience working on these galaxy 3s please tell me what this hooks up, controls, or what other replacement part I would have to buy that would have this ribbon included in it? Or with this ribbon being the way it is, am I going to have to buy the lcd,digitizer, &glass screen replacement that comes preassembled? I know its not the lcd flex cable amd doesnt go to the digitizer so im at a loss.
Im attatching pics so u will know what im referring to. Thanks for any help its greatly appreciated.
Pics after screen removal.
That's why I paid more and got the LCD+Digitizer. Cost more but made it a million times faster.
Sent from my Freeza MD4 Stock Rooted Galaxy S3
Yeah i understand i was just tryin to save a few. I can still do that and not lose but 10 bucks so notjhing hurt if i cant find a solution to this or just make double certain that ribbon being the way it is in the pic isnt going to hurt anything.

I'd go check out this thread and ask some of these guys. A lot of them seem to have attempted repairs already, and many of them have had to troubleshoot different issues. http://forum.xda-developers.com/showthread.php?t=1890708&page=78
I recently shattered the front glass on my Z1C. The display still works, but I get so many random ghost touches that it is unusable. Just wondering if anyone here has replaced the screen digitizer by itself rather than buying the digitizer + LCD screen together. Obviously it would be more difficult, however many posts about replacing both have mentioned the lower quality of the LCD image. Since my LCD still works, it would seem like a better option to use the stock one rather than a cheap knock-off. Not to mention it would be a little bit cheaper (I saw a kit which included glue, UV torch, tools, cleaner, and the digitizer for around $18 US). But on the other hand, with the added complexity comes additional risk that I will screw it up and end up worse off than just living with a duller display.
I’m still on the fence about which way to go here. Quality is subjective, so maybe I’m worrying over nothing and the new LCD would be good enough for me. I’d really appreciate your opinions.
Thanks!
Replace all.
I would suggest you to replace the LCD and digitizer completely. I broke mine in December last year. A small glass crack along the power button side made the top half of the digitizer stopped working. The LCD was fine though. I had to connect a wireless mouse to make a backup, copy some stuffs and use my old phone, while the replacement part came. Bought mine from Witrigs.com for $42 including front housing adhesive and shipping. Repairing was easy. Just heat the front part, lift it carefully. Swap the old part for the new one.
But like you I wanted to separate the glass digitizer from the LCD first. After several attempts removing the glue and the glass, the LCD had burnt spots. Maybe I applied a little too much heat in trying to remove the glass. And the broken glass left some permanent scratch marks on the LCD even after cleaning.
In all, trying to separate the LCD and glass has become very hard since last year. I've been repairing phones and tablets for years, mainly broken LCD or glass or both. From my experience, its better to change the whole part now.
Wish you good luck for the repair. Lets hope your phone lives again!!
same here. its very hard without professional stuff to change the display glass without damaging the touch under it. best way is to buy a new "complete" display module (glass, digitizer, touch) so that u only have to press the felx ribbon to ur phone. then using the glue stripes to fix it (using a hair dryer makes it easier to press it in).
Before the installation test the functionality
Hi there!
Can someone trustfully confirm, that witrigs.com is a good source for parts?
