What is the black stuff between lcd and digitizer - HTC Sensation

I was wondering what the black stuff between the lcd and digitizer is and where do I get it? My wife and son both broke their digitizers so I decided to replace them. The first phone I did was my wife's and I think I might have removed too much of the black adhesive because the digitizer keeps lifting up allowing dust to get trapped in between. I learned from my first attempt and myy son's went much better and is working perfectly.

I sat on my Fuze :(

Hi all,
I sat on my Fuze, short and simple. There is now a weird crack on the screen. I am very familiar with what a broken LCD looks like, there is no LCD "liquid" oozing all over the place, and the picture is not distorted in any way. It looks like some kind of lens INSIDE might be broken, and I think it's the digitizer. The cracks stop once they get to the dark grey at&t/HTC border around the screen, even though I hit very close to it, so whatever I cracked is under the top lens/protector.
Also, I read online (albeit at a cell phone repair website) that you can't replace the digitizer without ruining the LCD. Is there any merit to this, or are they just trying to convince people to pay their obscene $149 to replace a $30 part?
So I guess I have two questions:
Did I break the digitizer, the topmost lens, or somehow the LCD glass without damaging the LCD itself?
How hard is this to replace?

EDIT: I ordered this on April 17th. Fat chance AT&T will do anything about it, right?
That looks like just the digitizer... I purchased the digitizer already, but haven't gotten the chance to take it apart yet.... to be honest I'm very nervous about taking it apart.. I'm still trying to figure out how to split the two pieces apart (the keyboardbase and the slide screen....

If I'm not mistaken (and I might be), all this should take is removing the two small phillips head screws on the back of the screen that show when the phone is slid open. I landed on this thing while it was open, and drove my knee right into the screen, I'm surprised I didn't break anything else.
There are three more screws that you can't see behind the screen.... when its slid open you can only see 2 screws... There are actually 5

So we do have to take the whole damn thing apart?
Does anyone have any luck with AT&T replacing things that are clearly accidental damage? With all the horror stories I hear about refurbished phones and the chance that they might send me one, I'd actually rather take my chances at fixing this. I've taken apart a ton of phones and fixed them before, and worked at a cell phone repair shop for a few months. I still have most of my tools lying around, including all the screw drivers I'd need to open this.
I was able to find an HTC service manual that doesn't really explain how to replace the digitizer. It does describe how to get it in two pieces, but I wouldn't know where to go from there.
I have the digitizer in my hand... There is a thing that hooks up to the phone itself so yes i'm pretty sure you have to take apart the entire thing.... I think i'm gonna take the phone to NYC and have someone that knows what they're doing repair it. I tried to get warrenty repair, but they said no because it is accidental damage. i pretty much tried everything before I ordered a new screen.

Found a good complete disassembly guide in Russian, why does the screen have to be the LAST thing to come out? I am now looking to buy an LCD/digitizer combo, but I can only find the one from Brando that is made for regular HTC Touch Pros, and not the Fuze (has a camera cutout instead of the AT&T logo).
If I end up having to replace the LCD I'd much rather break it trying to save $50 than just toss it. Is it really that hard to separate the digitizer from the LCD?

has anyone had success separating the Digitizer and the LCD screen?

Well, we'll find out. I ordered both an AT&T Fuze digitizer by itself as well as an LCD with a digitizer attached. I'm just going to go ahead and replace everything with the combination unit and see if I can replace my broken digitizer without breaking my LCD in my free time. If it works, I have a spare or I can sell it
be careful I got my digitizer and they sent me the wrong one. They sent me one for a sprint touch pro....

Hopefully I'll get it right, I made sure to order an AT&T Fuze digitizer that made it clear it wasn't for use with Sprint Touch Pros or Touch Pros with front facing camera.
The LCD+digitizer I ordered though may very well show up as any of the above, if they're not already attached I'm going to use the AT&T Fuze digitizer on the new LCD, and try and make a new working combo from my old LCD to resell. I'll make a detailed step by step with photos as well.
Don't forget to read this
They just sent out my new one today.... So anyone that needs a digitizer for the Fuze by Sprint hit me up.... They told me to keep it so now I have an extra digitizer that doesn't work for my phone...
I think I can help you cos I repaired LCD and digitizer on Raphael a week ago. Digitizer and LCD are two separate parts joined by flat printed wires. If you need to change just one of them you will need to take apart whole phone.
Raphael consists from 2 main parts - 1. that one with keyboard 2nd part with LCD. You have to take apart both what is quite hard to realize if you this for the first time.
Once you are with your LCD you will see the flat wires grom lcd and digitizer meerged. Split them with your solddering gun carefully! Take new digitizer and solder flat wires together. Anyway there is no glue or liquid fluit or whatever between digitizer and LCD. But - remeber especially those who replacing just LCD - there is kind of black tape around the backside of LCD part (the silver side) - take it apart from old lcd and move to new one. If you dont you will see the rainbow on your LCD but just after assembling whole device together - it is quite concerning if you find out this kinf of malfunction just after such a hard work like a assembling this hellmade device
Good luck to everyone!

Thank you for some rather broken, but very helpful advice. Kinda sucks that I'm really happy since I don't have to worry about removing any adhesive, but now I have to sit here and solder flex cables. I shoulda bought a spare one
Do they ship these parts on pigeons from Hong Kong?
To anyone counting on being able to separate the LCD from the digitizer, DON'T. There is absolutely no way to separate them without destroying either or both. Also, take extreme caution when peeling up the flex cable, it is very easy to tear (I tore mine).
So my net cost, 80 + 50, LCD/Digitizer and Flex Cable = $130 vs. sending it to HTC $150. I advise anyone to just pay them rather than take this thing apart.
from my understanding people have done it before... Maybe you just had bad luck? Well we'll see when my screen comes in *crossing fingers*

Fact of the matter is when people say this is a delicate phone to take apart, they mean it. I worked at a cell phone repair store for a few weeks, and learned how to take apart damn near anything (thank God this was before the iPhone existed). Not only are both flex cables in this phone taped down in 100 different places, making them very easy to tear while removing the tape, the adhesive used between the LCD and digitizer is STRONG. If you really wanted to separate them, you might have some luck with a straight edge and maybe an hour. Good luck, I'll let you all know how this turns out once I have my new flex cable, since I conveniently tore the volume buttons off the original.
I just got my screen today so we're gonna see some time next week how we do on this screen replacement....I'll let you know how it goes....
So far no luck with my digitizer. Has anyone had any luck just changing out the digitizer yet? The guy that was suppose to do mine is backing out because he doesn't want to risk cracking my LCD. I don't blame him thats the reason I didn't do it. sheik124 what are you doing with your damaged fuze? Are you sending it to HTC for repairs?

Replacement Screen Problem

I cracked my screen a few months back, and right after it happened I bought a new digitizer to replace the cracked one. The install didnt go very well, since the tape used to adhere the digitizer to the LCD got mangled during removal of the original digitizer. Dust ended up getting between the LCD and Digitizer etc. One other problem I ran into was that the LED's that are supposed to illuminate the home/menu/back/find buttons were now shinning up into the screen and washing it out.
Anyways I got fed up with the dust and bought a new fully assembled screen/digitizer off ebay. I installed it last night and everything is great except that the lights are still shinning up through the glass and washing out the lower inch of the screen. I dont see why this would happen as there is really only one way to put it all back together.
Any insight as to how to get the lights to stop doing this?
Thanks!

[Q] Changing glass digitizer

I'm trying to change the glass digitizer on my phone, i'm also keeping the old frame, but when the glass was changed the notification bar was scrolling randomly as if a multi-touch was happening? any idea of what the cause could be. The phone is running stock rom and the adhesive used is lepage gel epoxy
When I changed only the digitizer, I never used glue to put it back... never had a problem with the touch.
I had just changed one with one that had an lg logo. It had these dots with connecting lines you could see when the light reflected on it. That digitizer had some issues with the touch scenceativity. I replaced it with one with a T moble logo, there were no dots or lines in it and it works like it was a new phone. I used a double stick tape to install them it holds good and if you have to remove it for some reason it is easy to heat with a hair dryer and ease off without breaking it. I guess I just got a bad one at first (lg logo one). Otherwise it was not much of a problem to change. The seller did refund 1/2 the cost of the lg logo one so I guess that was fare It works just not as responsive as the other.

[Q] Repairing a damaged screen

First, the story:
I dropped my phone and broke the screen. The screen is always black now, but from the sounds the phone makes, it sounds like it is still working.
This place has instructions for replacing the touch screen digitizer and the LCD; they also sell these replacement parts (for $40 and $35 respectively), (I had to obfuscate the URL to post this, so replace the underscores with periods):
www_repairsuniverse_com/htc-mytouch-4g-slide-screen-repair-take-apart_html
I'm not quite ready to move on to a new phone yet, so I am planning on trying to fix this myself. I guess my other option is to see how much it would cost for TMobile to fix it for me, but I am guessing that they want too much. My phone is rooted (s-off) and running a Bulletproof 1.1 image.
Now, my questions:
Has anyone here successfully been through this process? Any advice would be greatly appreciated.
I have not yet attempted to disassemble the device to futher assess the damage, so I do not know exactly what is broken, although the glass is certainly broken, is this what is referred to as the "touch screen digitizer"?
LCD is the actual display. Digitizer is the glass that sits on top of the screen (the part you touch)
If your LCD is broken, the picture will be messed up
http://forum.xda-developers.com/showthread.php?t=1592219
Replaced the glass (digitizer) without issue. returned the phone to t-mo since prior to that it was having an issue with the hardware camera button being stuck always on. So long as you're patient, technical, and have a steady hand, do it, it's fine, just follow-the step-by-steps, and keep your screws and parts seperated at each step
I ordered a new LCD and digitizer, and will probably have some time to do the repair mid-late next week.
I went with the Sony version of the LCD based upon discussion in the following thread (in the 3rd post iynnoji says they tried a Hitachi LCD but it did not work):
http://forum.xda-developers.com/showthread.php?t=1526595
It would be nice to know if the Hitachi LCD is incompatible, or if iynnoji had a bad component or some other issue.
Anyway, thanks for the feedback gtmaster and eclipsed. I'll update this thread after I attempt the repair. I have to admit, I'm sort of glad I broke my phone, since learning to fix new things is such an enjoyable process. Hopefully I'm still happy about this process after I finish the repair and attempt to power the device on .
Yay! The repair was successful! Not having a cell phone really made me aware of how useful one is. Next time I upgrade I'll keep my old device around as a backup.
So some notes:
The screen assembly was really difficult to remove, due to the large amount of adhesive. When I took it off, the LCD split in two, with half attached to the screen assy and the other attached to the adhesive. Luckly I was intending on replacing the LCD anyway. Anyone else performing a screen or LCD repair should beware that this is a difficult step, and will take time and care.
The Sony LCD (P/N 60H00523) works fine with our device. As I previously mentioned, it would be nice to know if the Hitachi LCD (P/N 60H00512) works, as its $15 cheaper.
I wasn't careful enough when placing the LCD on the digitizer, and managed to a few dust particles sandwiched in there. Not a big deal, but if I were to do it again I'd check my work before assembling the rest of the phone.
I used the adhesive paper sold at repairs universe around the edges of the digitizer and put the phone in the oven @ 170 F for 5 minutes after assembly, then waited 10 minutes before using it. Everything seems solid.
Again, thanks all for the help.

[Q] Screen Replacement

I managed to break the screen on my Optimus 3d last night, not sure if it was dropped or ran over. I found it face down in my driveway this morning and to my horror when I flipped it over the screen was completely smashed, however the phone is still working fine, minus the never ending ghost call issue.
What make the situation worse is Rogers just sent me out a replacement phone yesterday and I have to send this one back, in the next couple days.
So I called a repair centre and they wanted $190 to repair the phone, and stated they would need to replace the LCD and the glass screen. I know there is nothing wrong with the LCD screen, phone functions and all colours are good, just has broken glass.
My question is, can I repair just the glass without replacing the LCD? I have found the screen for around $30 on ebay. Based on watching the how to on youtube it doesn't look like too difficult of a job.
me too i have broke my glass of my phone and they said like your prize to replace thre glass but in my country crunncy and the screen work perfectly I don't know why they want to change the screen too it's annoying

If your LCD is working you only need the digitizer replaced (phone front + touch screen) which costs you around 20/30$ http://www.ebay.com/itm/Replacement...080?pt=LH_DefaultDomain_0&hash=item1c2d78e968 .
My touchscreen was broken (randomly pressing things on the screen) and I think the 2nd hand shop I got it from only replaced the digitizer I think based on the small dust I see on my screen.
This only works if your LCD doesn't show blurry or (partially) black (damaged).
