Finally fixed by Touch HD!!

To make a long story short:
I must have somehow put too much pressure on the digitizer to create a "newton ring" which in turn would not allow me to use the touch feature of the digitizer. I sent it to HTC USA to repair it. They noticed the "newton ring" as well as the modified ROM
They would not warranty the "newton ring" and said they would not repair the Digitizer due to the fact that it had been "hacked". They would replace the Digitizer, LCD and internals for $389.00. I told them they were smoking crack.
After paying HTC $25.00 for doing nothing they sent the phone back and I went online to order a Digitizer. I paid $17.00 which included shipping and I got it within 7 days.
The HTC service manual does not have a guide on how to replace the digitizer or the LCD. They really don't want you messing with it.
It was scary and I thought I had ruined the phone when I pryed the front of the unit open. At first the sticker to the digitizer came off(black framing) and then you have to pry the digitizer(its pretty stiff) from the frame. I destroyed the thin cable that led to the backside of the LCD but the new one has one already attached so I wasn't worried about that part. The LCD with a metal base plate is attached to the back of it. You have to slowly pry off the LCD from the backside of the digitizer.
Anyways I have assembled it back and everything is working perfectly. It was doing Micro-Surgery at times.
Just wanted to share my story.

Congratulations!!

How did you attach the digitizer to the LCD? Aren't they glued together or something like that?
Because that's where my attempt went terribly wrong: Instead of getting the digitizer off my LCD, I broke my LCD... I bought a new complete screen unit because I didn't know how the LCD is attached to the digitizer!

The digitizer is semi-glued to the LCD panel which sits on the back along with the thin metal cover. The digitizer has a thin flat connector that connects to the back of the main board on the bottom. I slowly pryed off the LCD(grayish white in color) from the back of the Digitizer. It came off and I aligned it back up with the new digitizer and the glue residue left over from the LCD adhered to the rear of the new Digitizer. the tricky part is the thin connectors that attach to the mainboard. You have to get a pair of tweezers to pull it from the flat connector. When you get the digitizer you will see the new connector. Attaching that and the prying of the LCD was the hard part.
I read somewhere some guy said he broke the LCD but in truth it wasn't the LCD that he broke. He pryed apart the 3 layers of the Digitizer and thought he ruined the LCD. I thought the same thing orignally then I when the whole LCD/Digitizer was in my hand I was looking realized that the LCD was the grayish/white panel on the back. One can easily peel away the top 2 layers of the digitizer and would think that it could be the LCD they ruined.
I hope that makes sense. It was the first time I did this and I didn't see the video where someone removed the Screen. I only saw the Russian guy who didn't finish the job because he was stuck at the end. I just figured it out the hard way.
Also the T6 works but I think a t5 would be better. I only had a T6 and it did the job.
I am so glad I wore gloves or I would have had some major finger prints all over the unit

Thank you for your explanation! But I'm still not going to attempt this on my own any time soon... We'll see... Maybe I'll change my mind if my digitizer is broken or scratched...

Respect man! You mentioned that you bought digitizer for $17. Is it possible to buy mainboard for Touch HD from that place? Can you please advise where I can get it. And how much it will be?

Got to love a bit of micro-electronics DIY!

This just shows that HTC are taking people for a ride - there are a lot of people who would have just paid the price they stated. As you've only replaced the digitizer, shows they were taking the mick with the LCD and otherwise, what are these "internals" that HTC said it needed I wonder...??

Just replaced the digitizer on my HD and it took about 1.5hrs. As long as you're very careful, it's not that hard at all.
Make sure you have the Service Manual though as it was a great help.

Have you got the link for the service manual?
Ive just had to order a Digitizer as my phone has decided it doesnt want to work anymore (6 months to go on contract too ffs).
Managed to get one from a UK seller with tools for £17 so im happy.

Hi:
How did you get the digitizer separated from the LCD?
I was thinking of putting two suction cups (1 on the back of the LCD, and the other on the front of the digitizer), heating everything up for a couple of minutes with a heat gun, and then pulling them apart holding the suction cups.
Does that make sense?
Thanks.

Mine had that pearl essence look to it for a good few months before it broke, not that im sure that has anything to do with it.
Just awaiting the delivery of the digitizer and hopefully I can repair it.

yeh mine had the pearl effect for a long time prior to it dyeing

ive followed the service manual and the video of the guy who gets stuck near the end, but how do you g et the screen out of the casing to get to the digitizer?
Its one hell of atight fit and i cant see anything o bvious.

Hi Guys
Sorry about the late replies - had phoneline probs!!
Assuming you followed the instructions in the Service Manual to take the rest of the phone apart, you've just gotta be VERY careful and push the screen out from the back (where the Circuit Boards where) of the plastic frame. At first, it feels like it's not budging but be patient and it WILL start to push away.
It seems to be held in with some sort of hot glue or maybe a contact sort of adhesive and I didn't try it but some heat from something like a hair dryer may make the job easier.
Many people have cracked their LCD screen during the repair but as long as you're careful not to bend the screen too much when taking it out, you'll be fine.
I peeled the 3 layers (outer glass ones and then the Digitizer itself) off the LCD whilst removing it.
Good luck - it's really not that hard. Any more questions - just ask ;-)

ive got the phone apart to the point of the service manual/video
which part of the back do you push out? doesnt look obvious as to whats attached and what isnt

Once you get to the last stage (I thinks it's the Speaker Removal) you simply push on the metal protector of the LCD from the back. You will see small holes in the plastic of the back of the frame where you can push something blunt through and push very lightly on the LCD to push it out.
If I remember correctly, at the bottom of the phone where the circuit board with the vibrator and microphone on it was sitting, there is quite a large opening with the metal backing of the LCD visible through it. I started pushing there and gently went all around the phone in the various small holes dotted around it.
As I said above, it won't feel like it's working at first but it will - just be patient and not too heavy handed!

My HD2 LCD screen broken -- Help!!

My LCD screeb broken yesterday. I have tmobile HTC HD2.But my touchscreen works fine.
Do I need to purchase this one
http://cgi.ebay.com/OEM-HTC-HD2-T858...#ht_2748wt_698
or
http://cgi.ebay.com/T-MOBILE-HTC-HD2...ht_1845wt_1014
Do I need to solder something or is just an easy fix?
Please let me know.
Thanks

Mine too
The links to the Ebay sale you posted are no longer valid.
My screen is broken also, just the touch sensitive glass (digitizer). The LCD is still in tact.
From what I understand the digitizer is harder to replace than the entire screen (digitizer+LCD) because the LCD is glued to the digitizer. There's a video on YouTube someone posted demoing the process.
http://www.globaldirectparts.com/HTC-T-Mobile-HD2-Digitizer-p/htc733745.htm
Has the digitizer for only $57 USD, but you have to order 3 at at time. If we can find someone else that's interested, then maybe we can go in and get one if that's all that you need also.
Cyph

I have done the digitizer repair, not exactly what I would call a fun time.
Easy to mess up your phone, need to make your own glue or double sided tape (to hold digitizer/lcd/frame together), about 4 little tiny wires that need to be placed correctly when putting the phone back together.
Thankfully the US HD2 does not require soldering the digitizer's connector to the lcd (the european one does), however again this is not a repair job for the feinthearted.
After all was said and done and the digitizer was repaired, the new one had the rainbow/oil effect when under a fluorescent light source, don't know if it is due to me using the wrong digitizer or what, but it did not look good. I had the same issue with a altell touch pro 1 that I purchased on ebay, it annoyed me then and it's back with a vengance.
Have fun, be very meticulous and watch the HD2 dissembler videos about 5 times before you unscrew one screw.

[Q] Which digitizer for my HD2 and where from?

I've successfully taken my HD2 apart now I'm not sure about the digitizer I need. My phone doesn't have a T-Mobile logo and it came with the leather pouch which I read means it's not the T-M version.
I'm looking for a new digitizer and the one that looks like the connector would fit says it's for the T-M version. Rather than go on about it here is a pic of my digitizer. I'm in the UK so if anybody has shopping suggestions I'd be grateful.

I can't say too much based from picture posted above ...
It could have already replaced unbranded digitizer or it's Telstra, European, Taiwanese version... Are the call and end buttons colored on your phone (green and red respectively)?
If You have enough money, about 89-120$, better choice will be to buy a LCD+digitizer assembly also named LCM, they will work at all versions of HD2, not only T-mobile or European, I tested the LCM from European HD2 with in a T-mobile version of HD2 ant it works perfect. So go on eBay.com and buy one

Call buttons are all grey. I've though about getting the whole combo but it's more than twice the price and I'm not exactly rich so it would have been nice to just get a digitizer. I was hoping there would a way to identify properly which digitizer I need. I've sent a message to one of the suppliers on ebay. I'll see what comes out of it.
According to this article the different versions of the HD2 aren't physically the same size in terms of casing. Do the LCM units fit all the same?

Let me help you:
#1.your picture is defining an uncommon/unbranded TMO(bile)US touchscreen(No doubt about, at least for me!), but grey hardware keys are for international HD2 model, probably you have a (let say) hybrid (home made)version between american(TMOUS) and international model;
#2.nevertheless, in your financial position, I'll look on ebay for an appropriate touchscreen model(there are plenty, most of them with very clear pictures like your's) for about US$30-40;
#3. if you want a combo, as far as I know(and pvii already said it) the 2 LCMs are geometrically identical, but the frame/chasis on which lay on the LCM is different(the american model is longer on 2,0-2,5mm);
#4. international model is cheaper & easier to find.
For more informations/help feel free to contact me!
Cheers!

May be it will be better if You post a photo of rear side of your display or at least say it's product number (from sticker on square copper pad, rear side), i.e. P/N:60H00300-00P is for T-Mobile and P/N:60H00295-00P is for international version.
If You don't have enough money for a european LCM combo, you can buy a LCD apart and digitizer apart, even from different sellers but you have to buy matching parts, both for European or both for T-Mobile version.

Thanks for the info guys. The serial number is the kind of solid identification that I was looking for. The serial on my screen ending in 300-00P indicates that it's the TMobile version.
My theory is that since this phone was bought when it wasn't exactly new on the market HTC had switched to the solderless screens which seem more modern?!?
I'm assuming that in terms of connection the digitisers that look like they will fit in terms of connection should work. I'm only worried about the dimensions of it since the casing of mine is smaller than the real TMobile version from what I can tell.
Since I can't find anything else on ebay I guess I'll order one of the TMobile ones and see if it fits. I'll look for a shop with return policy just in case.
Thanks for the help. If anybody has further suggestions I'd love to hear them.

Read carefully my previous post:
you don't have to be worry, the touchscreen, lcd and lcm are geometrically (length x width) identical!

Yupp, any LCM will fit on any model of HD2.

I wasn't sure which part was identical but if the digitizers are then what I ordered should do the trick. Digitizer should arrive this week so hopefully I'll have something to report about
edit: Digitizer arrived and fits perfectly. I guess my phone was some weird mutation. Solution is to just buy a digitizer with the correct connection, job done.
Oh and getting the right tape is a total *****. I had to take everything apart again because my tape wasn't strong enough!

I thought I'd post my findings and produce some cliffnotes on how I fixed my HD2.
Firstly, if you search youtube for "leo as" and "leo dis" you will find the official HTC videos on how to assemble and dis-assemble the HD2. They make it look easier than it is. Also, they don't separate the digitizer from the screen.
I ordered the tools to "dis" off ebay. Especially the T5 screwdriver was worth getting since it allowed me to find out which digitizer I need. I have a non TMobile version but needed the TM digitizer.
I found that using an old credit card type of card works very well for taking the phone apart. It can reach further into the phone and bends rather than breaking like some of the cheap tools from ebay.
Especially for separating the digitizer and screen it's great. I heated up the digitizer & lcd combo in the oven for a couple of minutes like the video advertised for taking the middle part of the phone apart (you'll see in the vid). Here comes the interesting part: Instead of sliding the card / tool all the way across the screen (between screen and digi), it's enough to just separate it around the edges. There is no glue or adhesive in the middle. It seems obvious now but I got lots of glue all over the LCD which was a bit** to clean.
Another tip that is worth repeating is getting the cheap double sided tape from ebay which is meant for Iphone digitizers (3M branded). I got three of them for £1 incl delivery. I used it to put the "middle" of the phone together. Screen and digi I did with cheap double sided tape which is working but I regret somewhat.
Another tip would be the whit cable (flash?) which goes on the bottom of the mainboard. I put it on top to start with. It's easy to mix up. Also it makes sense to put one end on before you put down the mainboard because that way you still have proper access.
Make sure you have good tape and be patient. I had crap tape and just slammed things together because I was so keen to see if the phone still works. I had to take it all apart again which almost broke the phone because it was coming apart in all sorts of places.
Overall it's like a big, fragile puzzle. I got the phone from a family member who had dropped it so all I had to get was the digitizer and tape. Now I have the best phone that ever lived
If anybody has questions, I feel like I know the hardware of the HD2 inside out.

I also took mine apart to replace the digitizer. I haven't got the new one yet though. I also watched the take apart vid on youtube. Unlike you I didn't disconnect the white wire from under the board. As a matter of fact, I left the other wires attached to the mainboard and just disconnected them from the GPS, camera and Bluetooth boards. At the end of the little channel that the wires are in, there was a little metal tab that held the wires in place. I just bent the tab up to remove the wires. Like you I used a piece of credit card to loosen the glued pieces.

the definitive HD2 disassembly and screen replacement thread

My HD2 finally developed the dreaded unresponsive touchscreen problem this week after just over 2 years use and as I'm now out-of-warranty I've decided to replace the lcd/digitizer myself.
Searching XDA and youTube for inspiration threw up a lot of scattered information, some useful and a lot more that was wrong and misleading so i'd like to establish a thread here with all the right answers provided, in detail.
This should also be of interest to those with dropped phones and smashed screens.
So far I've discovered:
- my unresponsive touchscreen is a hardware (not software) issue; caused by damage to the digitizer cable accumulated over time by repeated presses of the power button, to which it is physically adjacent.
- if the cable is only slightly damaged, a temporary fix might be achieved by pressing on the power button until the touchscreen starts responding again and then avoiding pressing the power button thereafter. ie. letting the phone timeout to sleep automatically and waking the phone up by pressing one of the other buttons rather than the power button.
- a permanent fix involves replacing the digitizer which requires an almost complete teardown of the phone. I'm open to any other suggestions from posters for say, repairing the cable although I haven't seen any as yet.
- although only the digitizer needs replacing, it's easier (albeit slightly more expensive) to replace the LCD and digitizer as a unit, which is the same part whatever version of HD2 you have.
- The disassembly procedure is fiddly with a lot of easily-breakable cables and connectors.
I've already acquired the LCD/ digitizer (part no. 60H00300-00P) from ebay, for £22.99 shipped, which was a pretty good deal as the standard UK price seems to be ~£38. The cheapest I found for the digitizer only (without LCD) in the UK was 11.95 shipped. The difference in price wasn't worth the extra installation hassle for me.
other required items are: a T5 torx screwdriver, a small jeweller's screwdriver set, tweezers, a guitar pick, an old credit card or similar, superglue (or double-sided adhesive tape) and thin (2.5mm?) single-side adhesive tape. also reading glasses or a magnifier might be handy depending on the quality of your close vision (i'm 54 so mine lacks somewhat).
This is by far the best instructional video I have found to date:
http://mperlitsch.hintergrundbild.com/htc_hd2.htm#Zerlegeanleitung
.. unfortunately its in German, which mostly isn't a problem as you can see what he is doing, except at the end as he describes (at length, rather than showing) the final step of superglueing the new LCD/ digitizer into the phone chassis, where i thought I might have missed some important details. Perhaps any German-speaking posters could fill us in on that procedure?
The above website also accompanies the video with some text descriptions of the various stages of disassembly which I will get google- translated into English.
There is another useful-looking instructional site here (hi-res pics, no video):
http://www.ifixit.com/Guide/Installing+HTC+HD2+PB81120+Screen/5651/1
Finally there are also some leaked official HTC breakdown videos on youTube @720p here:
disassembly:
http://www.youtube.com/watch?v=cL-jnUKufC4&feature=player_embedded
reassembly:
http://www.youtube.com/watch?v=t8Q7mXdcJ54&feature=player_embedded
I'll keep the thread updated as I go and I would welcome any help or tips from anybody that has already been down this road.
My aim is to develop a foolproof instructional guide that almost anybody can follow to extend the life of this great phone.

I've read that german thread as well and I'd agree that it does seem to be a very good guide, to read it in english open the page in chrome (or search for the thread in google) and let google translate it,
Step 32 for example translates to Step 32: Now as in step 31 and proceed to the bottom of using each 1 drop of superglue and moisten with clothespins along with the 30-minute fix waiting / drying time. In the bottom right where the flex board stops at the edge of the touchscreen and LCD connector watch film. There, only the metal bridge very carefully and very economical with wet glue. Important: Use sparingly only at the marked positions superglue! Never close the buttons at the bottom, even if the lure still should be as large. It is held there by our HTC special adhesive film wonderfully.​

Thanks, I'll have a look and see where his "marked positions" are. i already figured from the video that he was stressing about the buttons.
As this is the only part that I'm nervous about, I'd be interested in anybody else's experience of sticking the new lcd/ digitizer into the chassis. what did you use? and how did it go?
Presumably HTC didn't use superglue at the factory. Has anybody tried double-sided adhesive tape for this?
EDIT: I've just ordered some cheap generic double-sided tape on ebay, advertised as "New Clear Strong Permanent Double Sided Self Adhesive Craft Packaging Tape".
I'm still waiting for my LCD/ digitizer part to arrive and in the meantime bought another HD2, with a smashed screen, to practice disassembly on.
my own HD2 is currently behaving itself as long as I don't forget not to touch the power button.

i've now received my digitizer/ lcd part + (noname) double-sided tape in the post.
i've also found another XDA thread speaking in more detail about the step of fixing the lcd/ digitizer back into the middle chassis here:
http://forum.xda-developers.com/showthread.php?t=1341927
there is some debate in that thread over whether tape might be a better bet than superglue. the tape they recommend is 3M brand 2mm double-sided, for which I have sourced a supplier on eBay (item #281023942070 -- "3M 2mm x 50m Adhesive Tape Roll for iPod iPhone iPad - Transparent") for £5.99. I'm going to get a roll of that but may still opt for the superglue method ... undecided.

Mine was the same,
After seeing some videos I decided to buy a digitizer from ebay, it looked really easy on the videos. I bought one for 25€ , the ribbon cable looked strange but I decided to go on. After finishing everything the digitizer doesn't respond. I want to test the digitizer alone, any idea? I've access to a complete electronic lab, so there's no problem to use an oscilloscope or whatever.
Thanks in advance

sounds like you might have bought the wrong digitizer. You know there are 2 types, soldered and solderless (plug-in) which have different connectors?
Any pics? How did the disassembly go otherwise?
in the german video i posted, he shows how to reconnect the ribbon cables and test the lcd/ digitizer before glueing it in and reassembling the phone.

[Q] is that possible?a guy replaces full display (lcd+digitizer) in just 3.5 minutes!

just found a very easy way to replace the whole display in just 3 minutes by accessing it from the front side..
i am not yet allowed to post the link, but if you google this
IMPEXTROM CAMBIAR TROCAR DISPLAY HTC HD2
you will see the 3 minutes video
seems possible as there are 19 positive and just one negative vote on this video..
(my display was broken, but have worked for a year or so.
now it is frozen/ unresponsive and i have purchased a full display.)
but it seems too easy to be true ...
any hints?
thanx &cheers

That been set up for the video as you can see it been off before & the chassis the lcd is bonded to is clean of all bonding tape :-/
Also original has signal interference tape runing down sides across all 3 layers.
also if you heat the front first thing to seperate is the digi from LCD as the lcd to mid chassis is a strong bond.
Best way is popping them out of rear cover, fitting a pre built lcd/digitizer is not hard, just use quality adhesive to hold lcd to centre chassis & buy pre cut black foam tape for the top & bottom digi glass edges or rebuild is next to pointless without this done well.
I've done a good 30 odd HD2 screen & mainboards & no way I could do it to my standard via that video.

Hi Mister B - thanks a lot for your advice, i believe you are right!
but as i have never attempted to disassemble a mobile phone, is there a video tutorial how to do that properly for an absolute beginner?
as I need my phone functioning tomorrow, i'm considering to try it in the morning.

Not sure if Mister B will reply in time, there is a good thread here http://forum.xda-developers.com/showthread.php?t=1566179 with a video in post 2 else google hd2 disassembly youtube perhaps

Hi Robbie P,
Thanks a lot for the link!
Now it seems I will have to postpone this operation for a day or so, until i learn:
1) What time I would need (seems about 2h for a beginner)
2) What money I would need - as I have to buy these tools- what would be a price... i guess 10-15 euros?
(BTW Finally I guess that people who published aforementioned 3.5-minutes tutorial did so not to help us, but to make us damage our smartphones, so their services would then earn more, repairing it?
As I see no other explanation...Now found another such a scam video -
just google " HTC HD2 repair, disassembly manual ")
Cheers

Have a good read of link put up by robbie p
I done a few posts in it that worth looking at as you don't need remove the flexboard & volume button & antenna cables which saves a lot of possible accidents & hassle.
Most important thing is extreme care, volume button is damaged easily if pry of back badly or with screwdriver. antenna tabs are snapped off mainboard with poor handling while separating the layers.
It easy to do but first one is never perfect unless you really pay attention.
You don't need much tools, a basic kit from ebay for about 4euros will cover you along with things you probably got already such as hairdryer & razorblades etc.
Just buy good padded tapes to fit top & bottom of digitizer & strong tape to bond lcd to centre chassis

Hi Mister B!
Thanks a lot for you precious advise.
Will try to do it myself, not in a hurry, as soon as I get 3 hours spare time - hoping it would be enough.
Then I will need to install some good Android instead of the original WM6.5- but that is for another topic
My Qs:
You don't need much tools, a basic kit from ebay for about 4euros will cover you
this is what I got with my display from Ebay: Is it enough?
1 pry tool ,1T5 screwdriver and 1 T6 screwdriver.
Just buy good padded tapes to fit top & bottom of digitizer
I also got this one from Ebay: is it good? if you paste the title below into ebay.co.uk it you will see more details:
2mm Double Sided Layer Adhesive Sticky Tape Sticker for Mobile Phone Glue LCD
& strong tape to bond lcd to centre chassis
Which width, and should it also be double-sided?
Cheers

For tape you want this >

I assume you have lcd & digitizer pre-built new !?
You would be better off with couple more decent pry tools, the green ones tend be better than the blue plastic stuff.
I use 2 pry tools on top of HD2 either side of speaker grill as makes back housing removal a few second job & leaves not one mark if done right.
Only other thing you may need is tweezers & cleaning buds for old glue.
top digitizer tape need be right or blocks sensor hole or looks shabby.
Don't force the old lcd off centre chassis as if gets bent then never fit back right, warming it up with hairdryer helps ease it off.
I always have a spare button board on hand too as makes it easy bench test the lcd/digitizer hook to mainboard side by side with battery held on mainboard pins & spare button board used to power on, also good as likely find old board breaks if gone brittle.

tools I've got
Hi Mister B!
Thanks so much for your suggestions!
Yes, I've got the full display, and only the tools as on the photo.
My few Qs:
Only other thing you may need is tweezers & cleaning buds for old glue.
Could not find plastic tweezers, only metal ones... But those cotton sticks for ears i have
I could order the LCD tape, though it seems a long wait (7-10 days) for express delivery up here, so is there an alternative?
Thanks for a link to the button board! As I guess mine is damaged, for during last few months I had to press hard on the power button to get the phone responsive again. Then even this trick stopped working.
But also due to the longer waiting to get in from China - is there a way to test and learn if i need to replace it , before starting digging into my HD2?
Cheers

I would get the lcd digi top/bottom tape kit as what you got in big roll will be no good.
all else is good.
button board is handy as ribbons go brittle so can break plus you can use it to power up the device in a pre build test with lcd/digi & mainboard laid flat side by side & new ribbon plugged in to mainboard to power on. Most stuff makes it to uk pretty quickly, quicker order - quicker get it

Well, i will then order both items today, in hope it won't take too long to deliver up here (Belgrade, Serbia).
A video tutorial with all the tricks you have suggested would be the easiest way to follow, but it seems there's no such a video - yet.
Certainly, I'am either not sure whether will be able to film my own attempt.
Mister B - thanks so much! Following your suggestions, and the topic mentioned by Robbie P - I will likely manage to do the job properly!
Cheers

If have any question during rebuild post them here & I will respond as soon as see it.
Good luck ...

Thanks!
