My HTC HD2 Disassembled to the LCD

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

its not ... I have dust under the displayglass.

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...

T MOBILE HD2 LCD replacement

GUYS I need to know if its possible to replace the TMOUS HD2's LCD only as its cracked .. the digitizer is perfect
mally

YES, it possible. I did it on my phone and firend bought one broken too on which i replaced lcd (not digitizer).
You have two ways. First is easy way.
Buy complected digitizer with lcd and you have done on hour.
Second way is buy only lcd and replace it. But there you must very very gently remove digitizer at lcd. This is littlebit tricky. You must use oven. Place oven to 50 °C and place your, attached digitizer and lcd, to oven. 10 minutes is enought. Now you can more easly detach old lcd at digitizer. Be very very careful and gently. You can scratch paint on digitizer on lcd side and also lcd itself. Attaching lcd to digitizer are used sticker adeshive tape. You need buy it too. I dont want advertize one ebay seller but you can use same dealer if you want. I had with that dealer many actions and all time all is correct. And he have most items OEM. Ebay seller name is kr-net.
I recommend first way if you do it first time or not opened any phone before.
Bestest way is give your phone to repair.

Thanks a lot for your inputs mate, the phone's DIGITIZER is perfect , the LCD is cracked, should i still be gentle , since LCD is already broke,,,,

As i writed before:

Your digitizer is painted on bottom side on edges. If you scratch this paint you get scratched look later.
If you go change it itself, i anyway reccomend buy mounted lcd with digitizer. This work not easy deal.
And more. I readed over forum that someone have later digitizer sensity problems with no compatibility different lcd and digitizer. I cant confirm it. This what i changed works perfectly.
One hint is that HD2 and HD2 T-mobile have different lcd and digitizers. HD2 have soldered version and T-mobile not. You can see it on this ebay seller page, if you get one or another item detail look on seller shop page.

You can always contact www.ppctechs.com to fix it also.

[Q] weird lines on screen

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.

[Q] Digitizer replacement questions

Hi All,
Broke my glass + digitizer, but lcd ok. Got a replacement and managed to separate the original lcd, what I'd like to know is do I really need to glue the lcd to the new digitizer? I've put it back together just loose for the time being and seems to look and work fine. Any risks to just glueing the digitizer/screen to the frame and leaving the lcd loose inside?
Also, I still have glue gunk on the lcd screen, I've ordered some "151 sticker remover" to get rid of it, but it occurred to me it might damage it. Anyone know if it would be ok? If not anything else recommended, maybe something I could make at home?
Thanks!

I am in search for digitizer. How much you got it for? Any sources?
I believe this video should help you. It mentions that you have to glue digitizer and lcd.

Thanks, on closer inspection I htink my colours are a little washed out without the glue, so am just going to go ahead and do it.
I got my digitizer off ebay, interestingly I see the ones on ebay in India are twice as expensive though, I would have thought they'd be cheaper. I'd recommend just getting a digitizer and lcd in one though. Like this one:
ebayDOTin/itm/For-LG-E960-Google-Nexus-4-E960-LCD-Display-Touch-Screen-Digitizer-Black-/121465367279?pt=IN_Mobile_Accessories&hash=item1c47e66aef
Costs twice as much, but it's much easier to install; you don't need to buy as many tools, UV glue and gunk remover. Plus there's a high chance of breaking the lcd when separating it from your broken screen, so you could well end up having to buy both anyway.
I read something about the replacement lcds being lower quality though, I don't know how noticeable that would be, but if you pay with paypal you'd probably be able to get your money back.

The link is dead. But i guess the product refers to complete front panel of phone. I did same thing. The panels are China made. The quality is no where close to original. I suggest you to not buy it online. You should go to mobile repair store and ask them to do it. The reason is the panels are faulty and if so then they will quickly replace it. I did couple of time after which got a better one.

[Q] HARDWARE Please look at my photo and tell me if my phone can be saved

OK I'm an idiot I destroyed my digitiser when trying to do a screen replacement on my S4. Can someone please have a look at this pic and tell me if (apart from the broken digitiser) I have damaged anything else that would make digitiser replacement no longer viable?
Thx very much for replies

It's not just the digitizer that's toast, but the AMOLED screen as well. Those cracks near the upper right are where the screen itself is broken. With damage to the screen you're going to need to purchase a new midframe with screen and digitizer already attached to it. I don't know how much you spent on your glass, but the midframe and screen are going to cost about US$150.

Thx for reply . Could you just tell me if this is what you meant about what I need to replace the damaged parts?

Thx ever so much for help

That is precisely what I meant. It's the entire screen plus the midframe. You'll need to pull all the sensors and other small bits off the bad screen/midframe and put them on the good one, as the replacement part doesn't include the sensors. iFixit should have a breakdown guide you can use that should be of help.
