Evening all.
So my beloved DHD needs the screen and digitizer replacing. Ive done the necessary reading/ searching and ive also located what appears to be a decent replacement.
Here is the thing.......
Has anyone successfully managed to do the replacement and keep the " Home, menu, back, search " buttons lighting up post screen replacement ? If so i would really appreciate some pointers on how you did this.
Thanks in advance
i replaced a digitizer / display on my dhd once and did the same on some Hd2 before.
On DHD its really difficult to replace the screen / digitizer. You most likely damage the plastic frame around the screen and indeed the arrangement of the Leds are no easy too, but not too hard to maintain. I wouldnt change the screen of anyone others DHD, just my own.
Yes, ive read that the replacement process is somewhat fiddly / tricky and no i would'nt do it for anyone else either. Im going for a pre assembeled screen / digitizer.
digitalizer is glued on lcd and lcd is glued on the middle metal plate, removing lcd from the plate requires heating it and it sure isn't fun, even after heating it it is still hard to remove without damaging the plastic frame, if i were you i would take it to a service shop with already bought part and paied them to change it, trust me it is not worth the nerves and the time
I'm a very handy guy and I accidentally tore a ribbon cable separating the pieces glued together. It's very hard, worth paying someone.

yes, but it was a pain, hold the pieces in place with double stick tape and be careful not to bend them!
Yup I successfully managed to replace a digitizer but I'm also a trained phone technician.
The most important thing is to be very careful. You should never have to use force in order to disassemble a phone.
How to get the cracked digitizer off? Simple, use your oven.
* Place the display-module (Chassis, digitizer,LCD) on a tray, make sure the plastic parts don't touch the bottom, so that it doesn't melt.
* Heat the oven to about 80-100 degrees celsius.
* The display should come off pretty easily.
* If you've done it properly, you can use the same adhesive that was one the chassis/frame if not you'll have to purchase some slow drying adhesive and carefully place it around the edges.
* Carefully move the light-guides on the bottom of the screen to the new digitizer. There's a small amount of adhesive on them so don't get any sweat on them. If they don't stick just use a very very, I'm talking pixel size amount of adhesive on it to get it to stick.
That's about it. Thread the flex-cable around the display and use a tweezer to connect it.

I am experiancing some problems!
basically I think the manufacturer installed protective screen has come loose from the hard sensor (due to use?) and so the stylus is pushing on an air bubble, and with the software keyboard (virtual keyboard) the wrong buttons are getting pressed.
I dont know whether to cut out that layer with a scalpel (carefully) and use normal screen protectors that stick properly ... has anyone done this before?
Maybe you could apply heat to it to tighten it or something I dont know so I need help!
My phone is an alpine (xda2i) but other pdas must be having the same issue?
is it ok to cut the initial plastic screen that comes integrated with the xda?
Just make sure it is actually a protective screen and not the digitizer (the membrane that makes it touch screen and sits on the LCD) that your cutting away.
with a protective skin there should be no need to cut anything... I honestly think your talking about the digitizer - in which case take to a mobile phone specialist and they could heat sync it for you.
To check whether it is the digitizer or the crappy screen protector, you should be able to see the edge of the layer at the side, especially manufacturer orginial screen protector, they are really crappy. You should be able to seperate the layer (from the edge) with something pointy (e.g. a needle), and then peel it off from there.
If you didn't see any distinguishable edge at the edge of the screen, chances are you should not do anything yourself.

Thanks for the responses!!!
I have a feeling that it is what you are referring to as a digitizer. Do most of the mobile phone shops do this heat option? as after googling it, not much comes up, or is it referred to under a different terminology,
thanks in advance!

If your UK based you can find out more about them from apex laptops, google them...
I'm in Edinburgh, and it took me a while before I found someone willing to replace the digitizer.
This is not a common thing - but I think with the introduction of the iphone the markets for heat syncing will go up, I suggest freeing up an afternoon and go to some of those dodgy shops that offer the unlocking service, also some computer repair shop technicians might be confident in doing something of this nature.
Happy hunting!...

thanks for your help
whatever you do dont approach o2. they are ridiculous, they want to charge 350 dollars to peel off the old one and put a new on one. search ebay and you will find digitizres with screwdriver and peeling, firming tool for 15 dollars plus postage.
o2's repair guys say it "original" spares which make it so expensive....
right...........
rang up
rang up a couple of shops one doesn't do heat sync and the other does but the machines bust, he started talking about soldering etc...(does that sound like it?) but when i re-described the problem he started talking about 50 60 quid for a new screen! which I am not prepared to pay for the relatively minor problem
How is a digitiser different from a normal screen protector anyway?
(placing a normal protector on top of it sort of helped reduce the problems because it applied a little firmness over the offending area....)
O.k the digitizer is not a screen protector. The Digitizer is a membrane that sits atop the LCD.
Note: that the LCD is not a touch screen and the only thing making your device a touch sensitive is this digitizer
digitizers can be pricey, but the reason your guy is costing it at 50 - 60 quid is because he is the middle man and needs to make a profit. You can find digitizers from apex laptops or GPS midlands (links below) and buy them at trade prices
http://www.gpsmidlands.co.uk/index.php?menu=Home
http://www.apexlaptops.co.uk/touchscreens.htm
Dependant on your device will depend on the price.
My guy asked for 10 pounds to replace my screen, which I thought was more than reasonable because if he broke the LCD whilst replacing the digitizer (which he did) he was liable to replace it. Make sure that your guy will do this.
hope this helps.
after googling...
After googling for a bit, I came across someone who had these sort of problems with their own pda
http://jamescrisp.blogspot.com/2007/05/fixing-palm-treos-digitizer-touch.html
it seems that dirt stuck under the sides can cause the same kinds of problems,
after running a bit of paper under the corners of the screen I have found some interesting results, the problems I have have changed slightly and seem to rectify temporarily when I press down (rub down) on the screen...
so I might look at taking it apart with some tools off ebay or something and giving it a good clean... any recommendations on how to strip down and clean an Alpine....? actually I'll repost that in the aline forum if there isn't already a post there....
hope your confident in doing so - I'd take it to a shop if it pisses you off that much - taking it a part and cleaning might end up with you just having a big screen phone with no touch pad...
Up to you, hope your successful
Has anyone seen a good take apart/repair guide for the Inspire4G. Just got digitizer replacement and cannot for the life of me figure out how to attach the ribbon cable without totally disassembling the phone. Hoping to avoid this.
If this is the wrong forum, please direct me to a better one rather than flaming me.
Thanks
Fairly certain that ifixit.com has a good teardown.

Thanks for the tip, but I find nothing for the DesireHD/Inspire4G there other than a total disassemble for the HD that I've already seen, but really did not help me. I just need to change to touch screen. I appreciate the try though.
Got it apart. And kinda back together. Apparently it is not a good idea to reuse the double sided tape that holds the LCD to the motherboard and the digitizer to the LCD. At least the phone works. Now, must order some proper adhesive tape and redo the whole thing.... Took me about 6 hours for whole breakdown and rebuild. Doesn't really seem to fit back together all that well though. Maybe I'll videotape my next breakdown.
Couple of questions as my phone is in need of a new digitizer too.
Did you have any other adhesive tapes in the process?
What did you use to cut the tape that held the LCD together after you baked it?
Does the phone mostly feel the same now that you have it back together, or does it feel flimsy now?
I'm disappointed that it's this difficult to replace the digitizer.

Just so you know, I was a TOTAL noob in phone deconstruction. That being said, the old adhesive seemed quite sticky after i took it apart so I just reused it. Mistake number one. Once it was back together, i notice it slowly opening up like an accordion. The tape wasn't holding and the LCD, digitizer assembly started to rise up. I have since ordered some adhesive tape from the place I got the digitizer from. Definitely get the tape.
I did not bake it as in the video (i assume you watched the same one I did). I used an old spark plug gauge tool thingie to just cut through the tape. It was still really sticky so after i struggled to insert the digitizer ribbon cable, I just reused it. Don't do this. Get new tape.
I did have some plain old scotch double sided tape. I used it in one spot. Lesson: Don't use this stuff. Get new tape.
Did I mention that I think you should get new tape? All in all, it was quite laborious. I went really slowly so as not to brick it. When it was done the phone worked, but like I said the LCD raised up after a couple of minutes. The adhesive was not working anymore. At least I have gained confidence for the next take-apart. I can't believe i GOTTA go alll the way back to total break down. Aaaarrrgh.
So something like this should do the trick?

Thanks for the heads up... Where exactly do you recommend putting the tape? Does it just go on the black edges of the digitizer, or does it actually go on the surface of the LCD? Sorry if that's a noob question, but I haven't gotten the glass off and I want to make sure I have enough adhesive tape from the Ebay Vendor. Did you have any issues with reusing the mylar?
Sorry for the 1000 questions, I really don't want to shell out off contract prices for another phone...
Mylars were all reusable if removed carefully. I photographed every step so I would know what to put back where. Still waiting for my tape from Repairs Universe. The biggest two culprits are:
1] Tape holding back of LCD to the silver chassis frame and
2] Tape holding SIM FPC to the main board.
You might also tape the PCB cover to the upper board, mine was loose after rebuild.
That I believe that is it for the major tape requirements. Of course the digitizer needs to be taped to the LCD. I'm curious, though, the tape framing the LCD holding the digitizer seemed to have some thickness to it. Almost like foam rubber, quite thin, but thicker than regular cellophane tape.
Good luck. Let me know if you have any tips after your attempt.
Got the tape. Retried to rebuild with new OEM tape. Same result. The phone when completed expands like an accordion. The digitizer/LCD assembly does not stay stick to whatever is under it. I know when to admit defeat. Looks like I'm shelling out 500 for another phone. At least I have spare parts!
yeah i was going to do my screen myself till i seen the tear down & then called afew places around here that does screen replacements and said NO we won't touch the Inspire, i spent the money and let HTC fix it. was worth it they replaced the whole shell not just the screen ... IE lcd / digitizer / Outer case that was scratched and dented... basically a new phone with the guts out of my phone
I attempted to do this and let me just say that I too now have spare parts. I purchased a phone off of ebay. I didn't realize the no contract price went up to around 500.00 I should have gone directly to HTC. Live and learn...
I will be in possession of an HTC Inspire for testing purposes that also has a cracked screen. Not sure how bad it is but I was planning on just replacing the display for learning purposes. However it seems that it may not be worth the time spent.
If I do decide to give it a go I'll post my results here. First thing is to acquire new tape. Did you all purchase it locally or did you buy the adhesive online?
YouTube has lots of videos. Best to watch a few a see the best way. If you are scared to break it best you send it in for repair instead. Get a digitizer and screen combo.
I was trying to change digitizer to my tf300 by following this video http://www.youtube.com/watch?v=3_JRLd7lPv8 .The video is really bad, considering that this guy will show you a tf300 that has been opened before or something, because its very easy for him to do certain things, that i found very hard,and had to use other techniques.For example, i had really hard time separating the old digitizer and the plastic frame. In order to separate these two parts, i used some heat blowing gun (professional one) which turned to be very effective separating the digitizer from the plastic frame, but the plastic got wraped (as you can see in pic). Also, i don't have an adhesive tape or glue in order to stick the new digitizer to the frame so i m unable to stick the new digitizer to the frame.

You used too much heat. I don't think the warped frame will fit anymore. You might need to buy a new one. You really don't need heat initially though. Since you were gonna discard the broken digitizer anyway, you should've just scraped the glass off. Use this type of adhesive to glue back.
Thanks for you info!I was thinking of puting the frame on a table, put the new digitizer to fit as much as possible, put some towel on, and then heat it again by gently pressing it with the iron.Else, where can i find a replacement part?I don't even know the name of this specific part so i can search for it.

It's the front plastic bezel. Sometimes it's available used on Ebay. Best place to inquire would be Asus Parts located somewhere in Europe. I wouldn't try what you're thinking of doing unless you can straighten it again using the broken digitizer, as the screen is extremely brittle and the slightest pressure might crack it.
hello, i recently broke my z3's digitizer and a replacement is on its way, but i have some concerns, first of all, i noticed that there's a glue between my digitizer and my screen, i know how to remove it, i got some isopropynol , but i don't have the same glue used between the screen and the digitizer, will that be a problem ? i tried looking for it online but the only thing i was able to find is the adhesive stickers which i ordered.
has anyone did this before with their phone? i can barely find any useful videos that actually separated their digitizer from the screen .
There is only one type of glue that gives the best results and that is Loca Glue.
To change just the glass takes skill and patience, Lots of it.
Make sure u have the tools for the job. Demands a steady hand and the risk of cracking the lcd in the prosess is very high. I suggest a heatgun to make the process easier.
Good luck.
Hi guys
Sadly I have a cracked display...so there are no spare parts available and the shops in Germany would like to have something around 500€.
I changed in the past some Sony-Displays and thought about doing myself. I found on aliexpress some U12+Displays.
Sadly I didnt found a single "manual" or how to, to do this right - anyone can help?
Best regards
Maybe these vids from JerryRigEverything can help you out.
Good luck!

I just replaced mine yesterday and it was more difficult than any other one I've done in the past. Anyway I never found one single video on YouTube that showed the screen removal and pretty much had to play it by ear. There are a few videos that show the disassembly of the U12+ and each stops before removing the screen. My advice is to remove everything from the frame, I managed to piece together enough from the videos to know there are 15 screws to remove, one video said 14 but there's one more that's hidden until you've gotten under the motherboard holding the front facing cameras. Knowing I wanted to keep it simple I didn't remove all of the antenna wires, there's one at the bottom that's under the speaker cover that I left attached so I only disconnected it from the motherboard. Then the other I only disconnected near the vibrator, leaving it connected at the motherboard, so each piece had one wire that stayed connected. Meanwhile you'll have to undo every other plug on the device and with a little persuasion everything fell out. (Don't attempt to remove the button/pressure sensing strips along the sides!) Once you are down to the frame, and for me the ear piece speaker, I used a heat gun to soften the bond between the glass and the frame. It doesn't loosen up very easily, they are really bonded together. I got most of it and then began to chip away at the broken glass. You'll want a good heat gun for this part. I had to set mine to 300F to really get it to loosen up and then work mm by mm around the edge getting all of the glass and glue out of the track. This probably took me a half hour or more. I used E6000 glue but only because I would have had to order B7000 or any other recommended glue. E6000 is a good glue but just because many of the other videos I watched used B7000 I would have liked to use it too.
To install the new screen I used a syringe filled with my glue to follow the small glue track around the edge of the frame. Don't worry about squeeze out because this glue is very forgiving and wipes away easily with IPA Alcohol and a rag. I followed the old glue placement, adding a little extra near the bottom corners and a dab around the ear piece speaker holes. Then it's just reversing the process to assemble the electronics. Now here is another word of warning, the plugs are so small and some are not easy to align but be sure they snap into place and are flat when installed. I made the mistake of not getting the display plug flat and had to do a partial disassembly to correct the issue.
I didn't glue the back on but think I might today just to try and achieve the waterproof level the phone shipped with. You may have to glue yours but I had previously broken the back and already replaced it and the replacement came with a double sided adhesive strip that was still pretty sticky. If I remember correctly the original back was glued on and probably wouldn't have stuck if I had tried to just replace the back as I did.
One other note. After being disassembled and pulling the battery my finger print scanner didn't want to work. In fact it didn't even show up in the menu when I went looking for it but restarting the phone again caused it to show up. My advantage with the double sided adhesive was I was able to test everything and use the phone for a full day before committing to gluing the back on. Now that I know everything is working, the phone is charging and it all seems good I can glue the back on.
Best of luck
