This is all that you need.
Click on the link for the HTC Magician.
These steps I already knew, what I need is how to mount the digitalizer because I think that is solder to the LCD, and this manual does not explain how, someone knows how to do?
The digitizer is 'glued' to the LCD screen. Don't wast time trying to separate the two. I've tried it. Just replace the entire screen assembly. They are cheap on ebay.
So why sell the digitalizer if there is no way to replace it with a new?
I didn't say it's impossible, but it doesn't make sense to go through that hassle. Buy a new screen assembly and be done with it.
Need to be solder, but with tool can I use to solder? Anybody could give me the steps how to off the old LCD and then solder the new?
It can be done with a regular soldering iron with a very fine 'tip'. Since you are using a fine-tip, you'd have to ensure that there is no circulation of air in the room (which will quickly cool the tip of your soldering iron). Obviously, you aren't going to do this in a 'cool' room either.
Personally, it makes better sense to simply replace the entire screen.
I'm now under the impression that Antix already bought the digitizer, hence he is being so persistent in separating the two components.
I have not bought, I saw on eBay this digitalizer very cheap http://cgi.ebay.com/LCD-TOUCH-SCREE...photoQQcmdZViewItemQQ_trksidZp1713.m153.l1262, but it gives a lot of work I go buy a complete screen.
Thanks
done it
Hey, i just separated the digitizer from lcd and change it for new one. I used adhesive cleaner to soften the double sticky tape holding digitizer on the lcd. Moddeling thin knife to cut it arround (ull probably will crack the digitizer, i did ). Clean the contacts on the other side where the ribon cable goes, put a litle solder onto each one of the four of them. Do not forgot to use the soldering paste and good clean soldering tip. Put some double sticky tape around the lcd, cut it as required, attach new digitizer. Clean the end bit of the new ribon cable with lighter, so that only cooper lines are wissible. use fine sand paper to clean off the cooper . Put some solder on to the ribon cable, again use the paste. then solder it on to the lcd ribon. on the end put some (electric) tape over the joint to keep it strong and assemble your htc again. Works wonders, and does not cost £40 for whole new screen but only £6-7 for the digitizer.
cheers
I now have a great deal of respect for you since you were able to pull-off such a delicate procedure.
I just bought a replacement power button/ flex cable for Nexus of ebay. Took me around 30 minutes to replace it but its fully working right now. Its around 30 £ .
Item name it "Flex Cable Repair Parts for HTC Google Nexus one G5 1"
Just thought i let you know .
Any pictures?
Is it a tricky fix? I replaced my digitizer just fine so hopefully this wouldn't be a major repair job in comparison. Would love to have my power button working again!
I don't understand why you fixed it yourself, I sent mine back to HTC.

How much did it cost for the repair out of interest? Did it take them long to get it back to you?
Just curious if to you it looked like a bad button connection or a bad cable? I know sometimes the buttons get crud in them so they dont make a proper connection...
Great info. Too bad we don't have step by step pics. How did you take the phone apart and how deep did you have to go?
Does anyone know why the power button breaks? I have my N1 a year now and (luckily) i never had a HW issue. anyways i was just wondering why it breaks .
Step by step pics would have been nice.

The power button itself has a small cylindrical piece of plastic which pushes against and presses a small connection that sorta clicks (Which gives you the tactile feedback you feel). I think the problem occurs when either 1) The piece of plastic either bends/breaks/gets damaged in some way that makes that contact much harder to produce 2) The connection is connected to the phone via a cable/flex, however due to the Nexus one design it is bent around in order to be below the power button, while this is fine for the majority some devices, including mine, have seen the flex become damaged for whatever reason and either function intermittently or not at all.
It's also interesting to note that there is nothing holding the flex or the connection in place except for the design itself i.e. the battery bay plastic holds it all in place. My power button was never that responsive (But got progressively worse) so this may explain why.
Its always flex cable breaks and there is no way you can replace just the flex cable.You can find plenty of disassembly instruction over the net and yes you need to disassembly it to the pieces( still less to do than to replace digitizer.)I had a seal broken so i couldn't send it to HTC.

I did some googling and found a few images of that component, I remember taking it out and it was pretty simple so it should be just fine! Thanks for the info!
Is it the Power button part that you changed ?
Hi,
I have found a photo of the power button part, can you tell us if you changed the full part shown on the photo ?
androidguys.com/2010/09/08/manage-nexus-broken-power-button
And i think you paid it way too much expensive ?
Thanks.
I just replaced my flex cable as well as the loud speaker as well.
iFixit has a few pictures and there is a video on youtube, of the taking apart process. Unfortunately I can't post links
There are two little rubber parts that will likely fall out during the mainboard removal. One goes underneath the connector beside the sim card and one is a part of the microphon.
I wish I could have taken pictures of where those parts go, but alas, my only camera right now is my nexus, so....
BTW, I bought my parts at Mobile Brando. Quite well priced as compared to many other stores of the kind.
was it the whole board that you've replaced? or just the flex cable for the power button. can you further elaborate the steps that you've done?
So this is the item that you purchased? http://mobile.brando.com/google-nexus-one-mother-board-flex-cable-ribbon_p6193c1023d88.html
Can you confirm that the 3.5mm jack is on that board? Additionally, is that motherboard and flex cable for the AMOLED version or the SLCD version?
Do you need to remove the screen and risk getting dust inside there to swap this part?
Hi,
That's exactly the item, at that very same store. I also bought a loudspeaker as well as both back covers there. The audiojack is on board and I believe the flex cable has nothing to do with the screen type. The screen does not have to be removed.
I used those pics: http://www.ifixit.com/Teardown/Nexus-One-Teardown/1654/1
and this video: http://www.youtube.com/watch?v=cznogushN34&feature=player_embedded to figure out how to do it.
Basically, it's quite straight forward, given that you aren't a clumsy oaf ;-)
Remember the two rubber parts that might fall out when you pull off the mainboard assembly. (one at the bottom, for the microphon (http://guide-images.ifixit.net/igi/fpRmPyN6h12mtNvt.huge ,a bit to the left of the plastic tool) and one at the connector beside the sim card (http://guide-images.ifixit.net/igi/EOfeocuwhCRASB6M.huge , on the left part, somewhat down from the serial number sticker).
I have this probleme, but this part costs too much :S....
10. pin ON OFF way in board socket... u make jumper to on off buton
I have replace Power button for my N1. But you can reset your N1 by do'n need it. Except when you want flash rom!
Today I aquired a HTC Trophy with a cracked screen.
It was not cost effective to have it replaced by the workshop, so I'm attempting to replace it myself.
Following the MicroSD replacement guide by DominikZ, it's been a fairly simple and straight forward process, but I have now come to a point which I'm not sure how to proceed.
I've gotten to the point where I have the two ribbon cables disconnected, and have now separated the systemboard from the front. The front frame now contains the LCD, digitizer and speaker.
Does anyone have some tips on how to proceed from here?
What about the other 3 (black) screws? Torx 6?

Thanks for the tip Lance The pictures were easy to understand, especially when I don't read chinese.
However they did not cover removing the LCD and digitizer.

The three screws on the back of the lcd casing is not screws. Those are threaded cylinders, for attaching the front with the back.
Hey there
how far have you got with repairing the screen as I also acquired a HTC Trophy with a cracked screen. The phone still works so there is no rush but I need to know what I need to repair this unit?
Hey.
No progress so far. I'm not sure how the glass is attached to the front housing, but I have an idea that it might be glued on from the front.
You may be able to extract the glass from the front by using a hairdryer and something thin, like a razorblade. However I have not tried this yet, so I can't say for sure.
Good luck ;-)
There are digitizer replace videos for the htc desire:
youtube.com/watch?v=sXZqIjtFoAU
If the Trophy is build in a similar way you can see how you to remove the glass at 4:00
You can use a hair dryer instead of an oven.
Hi folks, been a long time lurker, came here after looking for a solution to this very problem, so, nlamer here's how to do it, be warned though it's not an easy repair.
(och, I cant post image links until I have made 8 posts :-S )
see attached photos, i'll prob need to do a few replies to post them all.
1:- Strip your phone down and remove the logic board from the chassis, carefully remove the lock tabs to release the ribbon for the LCD & digitizer
2:- Use a heavy duty knife ( I used a stanley blade ) to slice the adhesive holding the LCD to the digitizer, it's only held round the edges so you dont need to go too far in
3:- Peel back the cracked digi and just slice the ribbon, it's attached to the back of the LCD and your not going to be using it again anyway
4:- The LCD is held in place with the light grey adhesive strips, use a spudger to remove it, just be careful not to put too much pressure on it or you will damage the LCD, in my experience it's always better to have a replacement on standby just incase
5:- A quick check to make sure the LCD is still ok, you never know!!!
6:- On the old digi you will need to remove the three clear plastic tabs at the bottom and transfer them to the new one, these feed the LED's to the capacitive button's on the bottom, they are held in place with some adhesive & are not difficult to remove
7:- Remove all the old adhesive and apply some knew strips, I used 3M stuff here and trimmed it to fit but I dare say there are adhesive kits available on eBay
8:- Do the same to the LCD
9:- Line up the LCD with the marks on the digitizer and press it into place, the digitizer ribbon has a small piece of adhesive to attach it to the back of the LCD
10:- Place the display into the chassis, make sure the ribbons go through the gaps in the chassis and everything lines up before committing to pressing down
11:- If all goes well after re-assembly it should be looking sweet again.
Hope that helps yourself & other's out ;-)
Regards
Thanks for the instructions irepairtechstuff. It is greatly appreciated. I almost have my device wrapped up, and ready to go, but I'm having some trouble with the digitzer.
It seems behave as it pleases, and does not register pushes and swipes as it should be. Any tips on this?
Nevermind the last post.
I cleaned the connector with some alcohol, and now it works perfectly
I just got a trophy, I don't understand the adhesive verry well. I though you had to put adhesive on the underside of the touchscreen digitizer (along the edges of the screen) and on the metal frame, under the lcd or the underside of the LCD, but in this turtorial you see adhesive along the edges of the upside of the LCD?????
HELP!
Is there nobody who can help me?
Try private messaging the users who manged to get this to work. They should receive and email and might be able to come back and look at this thread.
So this just started off as a DIY digitizer replacement for me...but my MT4g is pretty beatup so I ordered some new housing from ebay to bring it back to life. The housing didn't come with buttons (mainly camera, power, volume buttons). I knew this and wasn't bothered because I planned to recycle the buttons from the old housing. Here comes my problem. The front buttons (home key/track button) are easy enough to replace. But upon closer inspection of the side buttons, I was at a loss about how to safely remove them. Originally I thought I'd be able to pop them out of the plastic pins with a small flathead or safe pry, but concluded that these were not coming out this way without damaging any hope of using these buttons in the new housing.
The plastic pins without the buttons in place look like this:
l__no.button__l
But with the button, the tops of the pins have been melted down holding them in place looking like this:
T___button___T
So I come to you guys asking for help about this. Is there any method of removing these and still be able to re-use them? Also include what tools I may need. Thanks in advance
First thing you need to get the right Housing For T-Mobile Mytouch 4g. The housing products in ebay are incomplete and can't satisfy your needs.
So go to alibaba.com you will get all the parts needed. Just follow this link.
Now you need to know all about how to fix it properly. The Repair Universe will guide you in this.

After reading several posts to find a cure for my HTC HD2 unresponsive touch screen,( Slider wont slide to open applications), I decided to verify a theory. Software... Digitalizer screen, or power button.
Ok, first I Instelled about six different android versions, and the screen slide still failed. I reverted the cell back to original t-mobile windows software, and still locked screen.
Conclussion: The sofware is not the problem.
After several attempts pressing the red power button, I got the slider to open. Briefly, it locked again. Pressed the red button hard and tried to work the slide on the touch screen. Again briefly worked. After several more attempts I got it to slide and while the phone was awake, everything worked perfect. I played games, oppened applications, texted, made phone calls, and the touch screen worked flawless.
Conclussion: The digitalizer (Thin top glass screen on top of the display that responds to touch) is not the problem.
This led me to belibe that the power button was at fault. I called T-mobile and after explaining the problem, they decided to send me a different type of windows cell. I want my htc. So I declined the offer and decided to void the warranty and take matters in my own hands. Yes, I opened my HTC HD2. This is what I found: After about an hour I had carefully taken my htc apart without braking or scratching the phone or screen. When I finaly got to the buttons on the bottom, I noticed how cheap they where made. A thin copper circle on top of two contacts held in place by tape. Yes you heard right, tape. After a while, beating on the red end key for maybe a year or two, the tape brakes and the metal piece slides to the side, and makes the button to malfunction, that's why the hard pressing to make it work. I tried A bottle of comppressed power air to clean them before disassembling the phone but the way they are installed It's not possible to clean them like that.
Conclussion: The red end key is faulty.
I decided to keep the cell alive so I went on e-bay and ordered the buttons, and just in case I also got a new digitalizer for testing purpose.
The buttons panel was about 4 dollars and some change, and the digitalizer (touch screen) was about 14 dollars for a total of less than 20 bucks. (Worth it)
So here are some pics of my cell buttons, and what it should look like. After I get the parts and assemble it I will conclude and let you know the final and official veredict. As of now, it all leads to the button.
Please do let us know how you got on. I have a HD2 which I'd like to get up and running again so I can play with custom roms and leave my other mobile alone...lol. Any chance you could link to the places you got parts/tape from, and what tools we would need?
Cheers! :good:
Did it worked ??? i am also in the same situation...please share the details,

listening in as well
sheesh! my wife's HD2 also stop responding yesterday, seems like clockwork that a lot are having the same problem
first have to find "how to open your HD2" w/o breaking anything in the process :silly:
Damn. The second time I'm hearing about the red button giving problems.... Will be waiting results from you dude!!! +1
still wayting for the parts
Well, I am still wayting for the parts, they are on the way. The parts I found on E-bay. The buttons panel was about five or 6 dollars, I also got the digitalizer which was about 15 dollars. As soon as I get the parts, I will assemble my hd2 with the original digytalizer (the thin top screen) and test to make sure the buttons were the problem. If all goes well, I will post a complete test result with links to how to get the parts, a link on how to dissassemble the hd2 and all info I can to help on this issue. I did a step back in life, and pulled out my trusty 7 years old motorola razr v3 and stuck my sim card so i can talk and text 5 words in 7 minutes. No internet... I need my HD2... Well, I will report back as soon as I can. Thanks for the wait...
@dragonsuicida
will be waiting for your findings & ways to dis-assemble the HD2 :fingers-crossed:
You were lucky to find the buttons' panel for 4bucks. I just checked out Ebay india, and the panel is 40bucks!!! What a robbery!
Wow. Me too!
I have been running Win6.5 still on my HD2, and have found in the last few days, my screen locks and I can't unlock it.
I came here deciding it was a software issue and was going to look into putting Android on my HD2.
I was slowly coming to the conclusion that it was the power button.
If I make an effort to NOT touch it - my phone seems happy.
It's amazing that we're all having the same problem about 2 and a bit years down the track since the HD2 was released - almost a built in expiry!!
And yeah - lots of details on how to fix it would be great.
The HD2 is too good-a-piece of hardware to allow a ****ty hardware button to be the cause of it's death.
New Keypad Button Flex Cable Ribbon For HTC HD2
Copy this:
New Keypad Button Flex Cable Ribbon For HTC HD2 T8585 and paste it on ebay, it will bring the buttons for the htc hd2. I belive they all come from china, but after I test them I will let you all know if they work and if they are worth it.
Copy this: REPLACEMENT DIGITIZER TOUCH SCREEN LENS for HTC HD2 T8585 and paste it on e-bay and it will bring you the digitizer for the hd2.
copy this: http://www.youtube.com/watch?v=YdOC3Xxo_k0 and paste it on your web browser, and it will lead you to a video on How To Replace Repair Disassemble Screen Digitizer. When it gets to a part that say that you have to put the phone in a oven, is just to melt the tape or glue holding the screen to the phone. I just used a hair dryer to war the screen enough to carefully remove the screen and the digitizer from the phone without breaking them, It works. I will be back soon with more info. I believe my digitizer screen is on the mail box now. Will report back...
I have same problem. Today I bought a flex cable ribbon and waiting for the dispatch (estimated in 2 days). I will also report back..
Same problem here!
Hope to hear soon that this is the way to go to fix it
You have to stick back the tape in the housing. The tape is electrically conductive. It connects the ground of the keyboard flex cable with the ground of the housing.

Be careful! There are two types of digitizer:
- Solder version http://www.parts4repair.com/htc-touch-hd2-touch-screen-with-digitizer-solder-version/
- Socket version http://www.parts4repair.com/htc-touch-hd2-touch-screen-with-digitizer-socket-version/
Be very careful when ordering parts, specially the digitizer they have several kinds, solder and socket, and different socket sizes. Compare parts with the ones in your cell to make sure, don't just believe the advertisements.
Hi, any updates on this? I'm also having this issue, but in my case, even pressing end call really really hard doesn't solve the problem... snif..
+1 on that
i pressed all the keys even the lower part of the LCD & flashed new roms but no joy :crying:
will bring to shop instead I'm afraid to open it up, it might end up even worse
Just be extremely careful when you try this. That flex cable is so incredible fragile and easy to tear. My roommate tore the volume rocker section right off of his HD2.
Hi dragonsuicida
Were you able to get your touchscreen to work?
