I posted in another thread about the issue of digitizer being glued to lcd. I had more pics to show, and decided disassembled pics are useful to all! So new thread for full set! If you want more I can get more! If I get enough questions I might make a tutorial for dis assembly.

Fixed problem!
OH NO!! what HAVE U done!!!
I know...The horror...I haven't re-assembled to see if still working...HA!
I disassembled because of a cracked digitizer.
looks like a fur or "plastic" carpet, hope you don't end up with ESD related problems
ESD as in ElectroStatic Discharge ^^
Phone still works just fine.
If anybody knows how to un-solder the digitizer away from the lcd, help would be appreciated!
New images added.
Next up:
digitizer/lcd separation
any updates?
Have you managed to fix it yet?
We all want you to succeed so we can operate on our own cracked ones! Maybe you need the "unglue" chemical - you know, like superglue has an antiglue for reversing it's stickiness. If you could find out what glue bonded it, then a specialist adhesive supplier probably knows how to reverse it.
I'm sure you'll like this (if it isn't posted here before...)

Well if they're cemented (hopefully with some hyper-glue), thats a GOOD thing. Then this will be (hopefully) my first device with NO dust under the glass.
Don't you people have insurances on your devices? Talk to the ensurance company and you will get a new device for a small excess - that is, if it's beyond repair

Floatheavy, and everyone else.
I'm currently on my second HD2, first suffered a hairline crack on the digitizer and it went COMPLETELY unresponsive. After getting the second, I had nothing to loose and disassembled the first. I got everthing apart up to the LCM, this module has everything (the glass digitizer, the LCD and the backlight) all cemented together. As I took the phone apart, priodically I would test that it still worked - everything except the digitizer. When I tried to separate the digitizer from the LCD and baclight I ended up tearing the layers of the LCD apart, now one layer is still glued to the digitizer and one is still glued to the backlight. I have yet to see how this can safely come apart and untill I can buy the LCD the phone is totaly screwed. I think one has to purchase an entire LCM and not just the digitizer.
For those that want to try separating the digitizer - BEWARE, noone seems to have found the secret yet! If I manage to discover something new I'll post.
Yeah. I tried the heat method to separate the digi from the LCD...
No luck
It seems it is more than the simple adhesive broken down by heat.
To get the bezel away from the LCM you can use heat to make easier, but to get the digitizer away from the LCD itself remains a mystery to me.
Anybody get any other results?
OKAY..
Pics updated again...
I was able to get the digitizer apart from the LCD, using a razor.
for separate lcd and digitizer
For separate lcd and digitizer, I used nylo fisher string... and it work good... just right my problem is how to past new one ? neopren glue ?
Honestly, I plan on just adding a dot of super glue to each corner.
I believe most phone adhesives are a sylicon based glue.
It`s almost impossible to un-solder the digitizer away from the lcd, i have succeeded a few times whit hot air and very sharp cutter, but still broke 2 screens from 5...it has to be a solution for this...anyway 3 phones from 5 its not the best rate...
Dear all,
anybody already experienced a broken touch screen?
My Leo fell from 50cm to the ground (tiles), just on the edge. The sound it hit the ground already let me knew - bad suprise...
If you have already some experiences with broken screens: Is there a way to repair it? Is it be affordable?
The device itself seems to work as usual. Even in the upper right corner, the sensitivity seems fair. But I fear a breaking screen as already some glassy bits drissel out...
Thx for tipps
TC
i belive its called digitizer on most touch screens.
not sure if HD2 has different technology.
but the LCD screen is separate from the touchscreen part(thats what you broke)
search ebay for HTC HD2 digitizer
heres the ebay link i bought a camera LCD display from them few times

Hey dude,
Check out this thread
forum.xda-developers.com/showthread.php?t=613954&page=20
I broke my glass on my screen and ordered a new digitizer, stripped it apart, broke the LCD in the process (a common occurrence as the glass/LCD glue is STRONG), ordered a new LCD, repaired and it works.. didn't quite go back together as it started (slight gap in case, buttons don't come through as much as they used to). Now have the problem of the 'bubble wrap' showing on the screen in a few places.
In short, yes it can be done but if you want it doing right get a professional to do it..
Any one else with there own experiences?
heat it up so the glue is soft and comes off easier, between the screen and digitizer.
if you have sun leave it in the sun to get it up to good temperature.
safest way since it will not get too hot where it melts.
A few weeks after using the Blade and I get this biggie speck of dirt, and that having a screen saver. : (
the good that has to be removed easily.

Search for "ZTE blade teardown" on YouTube. He shows how to.clean the digitizer

Help! There was a spot on the bottom right which had a lot of dust, and lost sensitivity. I decided to take the screen out. DISASTER! I managed to clean it, but now the phone lost screen touch sensitivity COMPLETELY! Anyone ever encounters this? The youtube has no audio instruction, I must have missed a step. I notice there is one part where wire is cushioned so that it touched the glass screen that lost its metal cushion. I am guessing because of this, it is unable to complete a circulation as one part is not touching the glass screen. (It's very very tiny metal cushion that I am talking about). I am just guessing. I am seeking help from anyone who encounters this and know what to do. PLEASE HELP!

I am not sure, the only thing I remember breaking is when I use a screwdriver to open up, must be too sharp and broke the little wire holder and the metal cushion.. Is there anything else that could have caused it?
I had alot of dust, after the repair ( i also got warranty) I did watch teardown movie and did it my self, pretty easy.
Hello.
The other day i dropped my phone and it just shattered the glass on the screen.
I'm still using it (but getting little shards in my thumbs regularly) but i'm just wondering what i actually need to get to fix it; is it the digitizer or is it the LCD as well (or are they the same thing). I found this:
http://www.ebay.co.uk/itm/NEW-HTC-D...K_Replacement_Parts_Tools&hash=item564688b2a0
Is this all i need? And do you think i would be able to do it myself? I don't have much experience with this sort of thing but i took apart my Macbook pro and the disk drive once. (Not the same scale i know...)
Thanks

Yes, the digitizer is the gorilla glass layer over the screen. It is responsible for the touch functionality in your device. If pictures on your screen are shown correctly and there isn't any dead pixel then your screen is intact and need not be replaced.
In all disassembly videos i see skipped the step where touchscreen is separated from lcd...
this step it's not so simple to do.
you need to melt the glue under under the touchscreen....
in some video is said to put in oven....10 minutes at 60 degree...but i didn't have success with disassembly these two parts
yeah, that step is difficult. I used a swiss knife blade (the small one) and could seperate the digitizer. I didnt put it in the oven or sun. But i guess its easier if u do. Just hold the knife steady parallel to the device.
I used double sided gluestrips to reatatch the digitizer but still the screen shows up a notch at the bottom of the device....seen this on many repaired DHD...so i think its very difficult to get a DHD where you dont see that its screen was replaced....
some part of the screen not function
some part of my touch screen not working. is this due to a dead pixels? if not what wil the cause of it?
Appreciate if you can assit to explain n perhaps some solution & advise.

This is a chinese s4 phone, after dropping it glass broke and screen displayed these lines as shown in pictures. What i want to ask is should i change the glass only or does it need a new digitizer? touch screen responds well, no problem there. just these lines. anyone have any clue if this can be fixed without changing the digitizer?
Change both digitizer and display

It's clearly that both are broken - and the digitizer is glued to the display, so you must change them both.

Thanks for your fast reply So do you know maybe if i can find a cheap chinese digitizer? not worth buying the original one which probably is not compatible, correct?
Look on aliexpress.com they have cheap digitisers and glass

Since this is fake Chinese S4 it's a real miracle to find part which is for your phone and one that works. LCD and Digitizer (glass) are not laminated in your case, so replacing them should be easy.

Don't think there would be a screen from a chinese knock off, and furthermore most of those parts aren't even genuine Samsung parts.
so not worth repairing a fake phone assuming you even can. buy something half decent at a 2nd hand store. hope you looked for malware on that phone before you started using it...
The glass might be glued to the digitizer, but it can also be unglued.
Take a blow dryer, set it on hot air and blow dry the phone. The glue will heat up and become liquid again. Use a guitar pick and try to pry the glass from the screen and slowly pull it off.
I've seen this being done once (on an original S4), so yeah, I'm sure it is possible.
After the glass is off you should see if it still has those lines or not.
