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 bought a new oem touch screen digitizer from dealextreme to replace my old shattered one but it is not recognizing inputs, except when I try to pull down the notification bar with phone locked (CM10 Jelly Bean - Quarkx).
This digitizer comes with a film on both sides of the glass and I removed both. I know that removing the outer film doesn't acctualy intefere but, does removing the inner film do since it is close to the LCD screen?
Edit: I've followed the instrunctions from here: http://www.repairsuniverse.com/motorola-defy-screen-repair-take-apart-guide.html

It is not the problem, I turned the phone on with mother board, LCD screen and touch screen digitizer all spread (cables connected of course) and it's still not working. I think my new touch screen digitizer is broken

I bought my digitizer from repairs universe. I also took off both films because the inner one had an air bubble. I broke mine because my proximity sensor doesn't work and i tried to remove a bit of the thick plastic which was covering the opening. now the very top right corner of the screen doesn't register any touches. I'm not sure what's wrong with yours but perhaps try a different rom. Or try disconnecting it again and put it back.

I tried both CM9 and CM10 and none is working, and I tried disconnecting and reconnecting countless times with no luck. I'll try to send it to customer service to fix it. Hope it is not too expensive.
Thanks!
Taking advantage of this topic, is there any way to configure 'automatically answer calls' without using the touch? CM7.1-11.
Hi,
I have attempted a glass only screen repair on my Note II which in hindsight was probably a mistake. Initially, I though things were going bad as I cracked and heated shards of glass away from the disassembled phone. Fully expecting to need to buy a new LCD/digitizer I eventually removed all the glass. Before cleaning the screen, I plugged it all back together and to my amazement it worked. Everything turned on and the digitizer worked so I turned it off and went about cleaning it up.
I then realized I could remove the backing that the glass was on, the bit with the black bezel. I don't know what this was or if I should have removed it or not. I cleaned what I think was the digitizer and LCD, put the new glass on and assembled the phone and this is where I'm stuck.
I try and power it on and all I get is one little red LED flash when I press the power button. When I press the power occasionally the screen flickers briefly as if it wants to turn on. I can't reset (10 seconds power) or hard reset (volume up + home + power). The phone is at full charge, it takes charge (my power supply "whistles") and the battery is at 4.1V.
Does anyone know what this symptom is or what I may have broken? I'm thinking I could have ruined the screen somehow, perhaps I shouldn't have pulled that last piece of plastic off or perhaps I have killed the motherboard but I don't see how..? Thanks for any assistance!
So I fixed the phone. Solution posted in case anyone else runs into this issue.
When I was removing the last layer on the screen or cleaning the goo off, I must have broken the screen. The red LED flash when I was turning the phone on is normal, it is just that the screen was not working. I got a new screen assembly and replaced the whole thing.
I've replaced about a dozen phone screens for myself, friends and family and I would strongly recommend replacing the whole screen assembly on a Note 2 instead of a glass only replacement.
I am a tech that does glass only replacements every day on s3 n2 and s4 and I can tell you that the black layer you removed was the digitizer and front half of the lcd that's were you messed up
