Just fixed my Digitizer

I have just got my replacement digitizer in the mail 2day from Hong Kong and installed it just now, all is working perfectly as new again. I did a hard reset when the touch screen was first playing up, so I have lost all my themes, settings etc but luckily my office docs etc are still intact.
Anyhow, I made a video on how to replace the touch screen, its only quick as I did not go from the disasembly part, as there is already videos and tutorials on this, so I just documented on the actual digitizer replacement, which is actually basic 2-5mins work, but I thought a vid would be good for any noobs needing it in the future.
Once I edit it all up I will post the video here.
If anyone needs help on replacing the digitizer just ask. DON'T be tricked into buying the LCD + Digitizer if you only need the touch screen, as it is very easy to do without the lcd, though some ppl disagree.
Thanks for reading, thread will be updatd with Vid asap.

Hi X86
I have a crack on the upper plastic case, thats prob. why I have dirt showing on screen. In your opinion where is it located and can I clean it ?

It seems as if (if the crack is on the actual original housing, not just a add-on case) that dirt/dust has fallen down inbetween the digitizer and the LCD, so you can see it through the touchscreen right?
This is fairly simple to fix, you will either need to patch up the crack with silicone or something (best from the inside so it does'nt look messy) OR buy yourself a whole nw housing which cost about US15-$20.
Then just pull your elf/in apart and use cotton tips and wipes to thoroughly clean the LCD and insides.
If you need any help, just let me know via PM or here.
?Good Luck!

Thanks
That was my feeling, now I just need courage to take apart the casing (either repair or replace )

Thanks for bringing up this issue in the forum and extending your hand to others.
I appreciate it alot.

Hi x86
I have read the sticky for disassembling the elf. Can you tell me if it's necessary to unscrew anything and remove the rear speaker in order to remove the front panel ?
Edit: I think I found the answer in the next pics, the 4 screws attach to the front panel, right ?

Hi, i've just entered the world of winmo. i've recently wrecked my Elfin. But i can't seem to figured it out whether it's the LCD or the digitizer is broken...
1) my Elfin's screen turns to white with a few red and black stripes on the lower left corner, it doesn't react to any touch gesture.
2) i can still activesync the device and seems that my SD card is still working, i could copy out my PIMcontacts...thank goodness
3) the alarm still rings the next morning, i assume my device is still operating, of course now i've taken out the battery.
4) i've ask the phone shop for repair enquiries and they said that the replacement parts are not for retail selling in my country, Malaysia... so it needs to send back my Elfin to OEM and takes about 3 weeks time and cost around USD $ 130 bucks....
5) my friends told me it wasn't worth it, thus i was thinking of looking for help online and finally i found this thread...
6) can anyone offer few pieces of info? i thank you 1st.

That sounds like both a Digitizer and LCD issue.
Red and white strips is caused by the screen, while the phone not sensing your fingers is caused by digitizer.
But you still managed to use something like mymobiler to rescue your stuff right?
Yeah, you're in Malaysia right? In Singapore, to get this items, we have to get it off ebay or dealextreme.com.
But be careful with this, it void warrenty.
If you send it to HTC service centre, it may cost $160> Singapore dollars.

Tips for buying a used universal

Hello! could people please share tips and things to remember when buying a used universal? I mean what are the things that you should do to check or find tell tale signs of defect, hardware, the firmware the os, I have already done a search in the forums and already know some, but there might be things that I have missed, so help would be very nice, I will be meeting the seller so I get to inspect the device up close so it would be nice to armed with the info how to inspect the device from how to check the bootload etc.
Thanks for the help and I hope that this helps others too

The Universal can be bought cheap at german eBay. Look for MDA PRO. You should be able to purchase one for around or less than 100 Euro.
Preferably look for the following signs:
1) Unmodded. Many users got the Universal within a contract from the operator, but did not use it much, because it is too big for them. Such Universals are normally in good condition. When advertised that it ships with an OS different than WM5, you know that the owner has been flashing it. I personally don't like that, because that means it belonged to a power user and must be more worn out.
2) Warranty stickers. Make sure the hinges have the warranty stickers inside. If they are missing, the device has been opened. You don't want to purchase one that has been opened.
3) Screen. Screen should be without scratches and should have had always a screen protector.
4) Speaker. The external speaker which is used for calls can break, as it is fitted with some kind of pogo pins. Make sure it is working.
If you get to test the device first, do as this:
- do a call (bring your SIM card)
- check WLAN and Bluetooth (bring a headphone and try it somewhere with WLAN activity)
- bring a SD card and see if it is read
- check for bad pixels
- play a song
- take a picture
- try the keyboard and touch screen
- try all the buttons
If everything works, that is the best you can check it for.
Of course it could break the next day, but it shouldn't.

Great guide vma!
I´ll just add:
Take special care on the swivel piece (The one that gives Uni it´s great and unbeatable form factor: PDA - Micro Lap top)

take care of another thing when i bouted my universal after i used it for about 1 week the phone was hangs soo much the reason was in the memory crd .....so you must try a memory crd and play a small video on it about 10 minutes

The most important thing everyone forgot to mention is USB port. When looking for a device, see if the port moves in any way or wiggles in its opening. See if the device synchronises with AS, charges etc.
The fact the device had been flashed or opened wouldn't play a huge part for me if everything else works well and the body is in sound condition, e.g. the hinge is not loose, the screen rotates and closes properly, all keys are present and work, keyboard backlight works with and without sensor etc.
Speakers don't just break, as post No2 claims (POGO PINS??), but it is good to check that phone is capable of making/receiving calls, you can hear the other party and the other party can hear you, can play music and earphone plug is in working condition/attached properly
Not reading SD or SIM card is a biggie, dim screen, lost touch sensitivity, scratched or damaged digitizer, worn out buttons - all obvious signs. You can open the back, remove the battery and SIM card and check for a small white blotting paper sticker covering the small mainboard pins under the SIM card, any change in color towards pink - do not buy.

@enigma1nz:
Shame on me, I did indeed forget the USB port!!! You should of course check both: charging and Active Sync connection. A broken USB connector is a mayor issue and hard to solder without proper equipment.
Regarding the speaker: I am speaking out of experience, as one faild on me. The speaker is like a small button and it has two contact plates. They are not pogo pins, but act like them. The speaker will be pressed by the case against two contact points on the PCB. What happens is that apparently some car-holders do too much pressure on the sides of the Universal casing, causing the speaker contacts to bend back and forth everytime the phone is placed or removed from the holder. After a few months the contact gets worse and worse until one of both plates brake off. Because they are so tiny, it is impossible to repair the speaker - believe me, I have tried. I ended up buying a new speaker cell at eBay.

And believe me, I repair devices for a living. Thanks for the run-through, although I could give you the same. It happened to you, doesn't mean it happens often or it is a fault in design. I could give you a list of design faults in quite a few models of expensive cellphones on the market today, the mentioned speakers are not one of them.

I appreciate, the help people! any more inputs? I am happy that all the previous posts were, about how to inspect the device upfront and some other useful tips what to check other inputs will be highly appreciated

Battery can be also considered. Some are sold with good batery some with dead battery. It is not so expensive, but costs something. In general if battery shows less than 50% and devidce still works (even under load) that is a good sign.
Also as for the touch screen - the best test is to open note taker and try to paint something. The painted line must exactly follow the stylus movement if it jumps somewhere, then the touch sensitive layer is bad. I bouht such UNI on eBay (was described as perfect working order), had to replace the digitizer myself.
I do prefer buying not working UNI's on Ebay with good display. Once I bought not booting one - mtty job fixed that. Other time I bouht one where the display was still off - the flex cable popped out from connector. Etc....

Thanks for all the advice people! now, please welcome me to the HTC universal family, (well actually, I have a Dopod 900 but what the heck all are the same right?) your inputs had been essential, for me to get my new baby without any hitches I hope that nothing manifests after the one week assurance the seller gave me
Special thanks to enigma1nz for all the patience and help provided to me I asked her a lot of questions in the pm's but she answered in full detail
Now I have my own device so I will be flashing away, I hope without any problems. Again my thanks to the community hopefully there are more inputs for others who are thinking of buying their 2nd hand universal via meet ups

Excellent news! Congratulations!!! And welcome to the Uni family, of course. As you can see, we are one friendly bunch, all help and support will always be available. Have fun

Damn, I was hoping to do a very good Marlon Brando Godfather impersonation with 'Welcome to the family'

Touch HD (Blackstone) Screen & touch repair, pics and tips inside!

Hi XDA peeps.
I would like to share my notes and pictures of my recent repair i performed on my touch HD. If you end up suffering from the Newton_Ring problem or cracked lcd, and decide to purchase a factory assembled LCD + Digitizer, you can use the Official Service manual and this thread, to perform the repair.
The Battery and the Battery cover have been removed.
Lower mainboard cover and inner housing have been removed
the Digitizer & LCD (preassembled) replacement Part, beside the damaged Blackstone.
Removal of the GPS Coaxial cabling.
I'll skip past the wifi coax removal, but will like to note that you will find a spare coax socket on the mainboard next to the wifi one, so dont get those mixed up when reassembling it!!
both Coax cables removed. (bad quality picture)
Removal of the Ribbons Mylar
this is the removal of the Ribbon plug.
Removal of the Volume buttons and its petite PCB. Take your time, dont break the ribbons or damage the pcb trying to remove this.
Removal of the mainboard phillips screw.
Power PCB slot removal, this ones tricky.
Unplugging of the 5 megapixel main camera, a nice and easy step.
Note: Please be aware that the whole Top PCB is very fragile and does actually bend, hence the term Flex PCB, be gentle with this component.
You wont see this part of the repair listed in the official manual, infact when I had a google around, there was little to no information on howto perform this anywhere.
Let me make one thing certain, if you've just spent like an hour on the above, while following the Official service manual, squinting at the poor quality photos (or my poor quality photos ) and you're feeling a little impatient, take a decent break before attempting the above!
Because, for the above procedure, you need to tear off the 3 layers of Digitizer and LCD from the front of the phone, if you don't take your time with how you do it, you'll dent your frame (a lot).
you won't find this in the service manual, if you worked out its significantly easier do a factory pre-assembled Digi+LCD replacement, and if you don't purchase the housing along with LCD and Digitizer, then you'll need to take the front Speaker piece grill, and transplant it to the new part.
Note: that you don't need to add any extra glue to perform any of this.
Next you simply gently fold a ribbon so you can place the new part into the old frame, and you'll end up with something like this:
I also did a lot of very minor aesthetic damage to the inner area of the frame, between the frame and the touch screen.
Take your time to prevent this, also if you don't care for the old part at all and aren't replacing a LCD or Digitizer standalone, you can pretty much gain access to the layers from one corner then tear the layers away from the glue with your hands.
Next proceed to rebuild the phone following the above in reverse or keep following the service manual (or both, is probably the best way IMO)
Note: Don't forget to place the camera back into the reassembly as you're re adding the coax wires. The service manual won't instruct you to do this.
Install back your flexible and mainboard pcb. as above.
The above is with all the boards, cables and camera installed back into place.
Verify the replacement part is good before fastening in the shell casings.
Lastly the two shells are fastened back on and the battery is put back into place.
Note: When installing the main shell, be very considerate of the camera, while at the same time, ensuring that none of the coaxial or the vibrator cable falls out of their desired places.
OK, if you have the HTC Service manual PDF, and need to repair your Blackstone (and want to DIY), it can be done albeit some instructions are clearly omitted from the official service manual.
One final note, When researching on what part to use to perform the repair of my Blackstone mobile, I read a great many people have attempted to repair their Blackstones and failed miserably, so even if you're savvy with repairing small electronics, the general suggestion is to get a pre-made digitizer & LCD, it is without a doubt well worth the price difference of a Digitizer or LCD standalone.
Thank you for taking the time to check this out, I hope someone may find it useful and save them from a bit of misery.

you are fantastic! i will try to replace the screen in next days...your guide is the best!
very thanks

excume friends, but i'm from venezuela...... i buy a HTC TOUCH HD in miami, the february 2009, ,i phone present this problem, the LCD work fine, but the touch no responding, anybody know where can buy it...... i don´t know how call the replace..... digitalizer, LCD.... how???
Thanks and excuse me by me bad english........ i know, soooo bad.....

Believe me it's almost imposible to replace just digitizer.
I have similar problem few weeks ago, and I buy pre-made LCD+Digitizer and replace it without any problem. I bought my from ebay. UK reseler. 65 euro. I heard that you can find it for lower price but I was searching on ebay.de so maybe on US ebay you can find for less money.
Don't bother to replace just digitizer, just to go 40$ less. Sometimes is batter to give 40$ more but to do job without any problems. (PS It's very, very hard to detach factory attached LCD from frame without braking it!)
Good luck!

Thank you so much, look for us on ebay or on amazon.com to see them .... any questions do not hesitate to do that around here ...... thanks again

Greetings, I got this on ebay usa,

... What do you think? Does this serve me?

my baclstone started acting funny with screen alignment getting messed up and than it completely stopped responding...
even the touch sensitive hardware buttons donot work no more...i have hard reset many times did task 29. i have changed different roms and went back to stock rom but screen doesnt respond at all... not even the backlight turn on to full brightness when screen is tapped?
anyone have any idea whats broken lcd or digitizer or both... or maybe something else.... and there is no official htc repair shop so i probably gotta fix it on my own

Got Touch HD from someone I know.
He has scratches on the fone screen, so he decided to DIY by replacing the screen, he did not manage to screw everything together so he gave it to me...
I have tried to follow instructions both here and another thread which points me to videos that I can watch...
The problem is that I have black screen, I can hear the sound when turned on. Just no life on screen.
The screen was super glued on so there was no reponsibility of removing and check if eveything OK.
Could it be that the screen defect?
Have google but found no info on how to attach screen to the fone !!!
There was just one ribbon cable, I believe from the screen to the main borad and it is attached to the main board....

OK
Have had some free time over the weekend, disassembled the phone and found that 1 of the fles connectors was loose. Reconnected and all was perfect...
Now I have a fully working phone
Thanks for the guide....

Don't try to replace only the digitizer...i suggest to disassembly the phone first to buy the digitizer.. to see how much is hard to detach to lcd without broke lcd! if you can detach you can buy only digitizer!
i bought the digitizer but i broked my lcd to try to change...with Lcd+touchscreen's block I ve changed in 10 minutes and it is perfect!

Glad to see this has helped others.
My main intention was to cover the steps missed by the not so comprehensive service manual, if it was more comprehensive i probably wouldn't have started this thread to show how I repaired mine. was quite a few too many important steps missing really. (re-adding the camera, etcetera)

Hi all,
I just replaced the lcd screen of my blackstone and got a new touch screen, I put all together but the touch screen seems to be dead. Is there anything I should check? you always talk of touch panel and digitizer like two different layer, does this mean that I should have 3 different pieces (LCD - digitizer?!? - plastic touch panel)? Because I only have two, the LCD and the "glass" with an outgoing flat cable. In the case I am not missing anything, should the touch panel work even if not in contact with the screen ?

If you got one pre-assembled (which we call LCD + digitizer), it would actually just be one whole piece.
If you have two pieces, then you have a LCD screen (the glass one AFAIK) and a plastic layer (the digitizer)
My replacement part came in as one, and in the OP I disassemble, and remove it and place the new on in the old ones spot.
Sounds to me like youve gotten the parts not pre-assembled by the manufacturer, unfortunately its common for non- pre assembled ones to not make contact to eachother properly when you assemble it, some people reported being able to do it, and others from what i've read found either partial or no touch capability, but it would likely be the digitizer contacts are not touching the LCD contacts (kind of a ribbon on the plastic piece)
It maybe worth just getting a pre-assembled replacement. if youve already used the current one and cannot fix it.

No it's not preassembled but you probably solved my problem. you basically say the touch panel and the LCD MUST be in touch in a specific point to close some contact (maybe the lower LCD ribbon must touch the lower part of the touch panel?)!! If you confirm that than probably that is my fault. I've seen some videos on youtube where the touch panel works even if it's away from the LCD but it was not a blackstone and probably not a resistive touch panel.
Please confirm I got it right, you probably saved my blackstone.

as far as i know, the digitizer will have some kind of ribbon, on the LCD theres contacts or a socket for that ribbon, you can see (poorly) in the pictures I took, where I show the LCD and digitizer and a layer (digitizer and face place layers) of torn apart.
I looked around my room for my old damaged screen but unfortunately I can't find it I think I may have disposed of it.
lucky, ebay type sites do have some pictures of the digitizer and its ribbon as you can see in this picture - link (I googled this and found it here
that ribbon would likely attach to the lcd panel, I'm quite sure if they aren't making proper contact the touch won't work.
But, having said that, before I made this thread, while reading about others who did a repair without a pre-assembled part, they mentioned that the digitizer part contained many tiny bubble like resistive cells in the digitizer layers, its imperative you don't damage the any of these touch cell things, because if they somehow get damaged, even if you get the digitizer ribbon to make proper contact with the LCD board/slot/contact (which ever its supposed to plug into), if those tiny cell break in the digitizer the touch wont work (could be partial, or could be overall interoperability) and if that happened, it would be a circumstance where you'd need to source another digitizer.
this is more or less an elaboration on my prior post I think.
What I can say for sure is before I fixed mine, after some searching around on these forums and on others, I found that most of those who did not get the digitizer, face plate and lcd factory pre-assembled did not fix their handset (only a minority did), they either ran into a problem with the digitizer making contact with the lcd panel, or they somehow damaged the digitizer resistive cells.
Also, since I did do mine with a pre-assembled part, I cannot say absolutely that the resistive cells will be between the faceplate layer and the second layer of the digitizer replacement part (like you see in my pictures, I ended up with 3 layers) it could be that the resistive cells are exposed on the back of the last layer and need to sit against the lcd, once again though, I'm not sure about it because I did opt for the more expensive easier choice to fix mine up.
Hope you get it all working smog

No way, tried to push lcd and digitizer together without any result. I don't believe there is something that can be broken on the back of digitizer (Resistive cells???) but I hope you are right, I am waiting for a housing I bought from HK it's complete with a new digitizer ... we'll see
Thanks a lot

Hello, great guide but I am still having a problem and I wonder if it's with what I bought; Off ebay I got the plastic and the glass attached to each other as I assumed thats all I needed because my lcd works fine. So I connected it all up and it only slightly works, where you touch the screen is actually showing up as quite a bit below (depends where - top left corner works fine but if you click the center of the screen the phone thinks you're clicking at the bottom).. I have tried calibration with no luck.. Any help/suggestions greatly appreciated.
Thanks

Afraid that theres not a lot you can do, if you havent fully reassembled it yet you could try reapplying the digitizer layer but I think that even trying that could make it worse then it is.
Like i said a few times, I wouldn't try replacing the digitizer on its own, I read up on it before repairing mine and concluded it was too much risk or trouble and just got an all in one lcd + digitizer which I used in the guide.
anyway these phones are quite old now, its hard to justify spending on an LCD and digitizer to fix one up.
you need to decide if thats worth it to you or not.
Infact, my blackstone has Newton rings again on the replacement screen, im not certain what squashed against it hard enough to cause them but it happened recently, the digitizer on mine is still working even with the newton ring damage so Im not planning on replacing the screen again.

Okay thank you very much for your help,
Are they still good phones though? I have a nokia 5800 from around the same time and i'm bored of it now but can't afford a new one so i bought this one really cheap as broken and was just going to fix it.. Or is it not really that much better?
Thanks again for your answer

they're considerably faster then nokias usually, i had the 6600, 6260, 9300i and they were all considerably slower ARM processors.
but It will all come down to what OS you run on it, if you do put a WinMo 6.5 rom on it it will be slow to the degree where its unusable. but if you use a 6.1 rom on it then it will never suffer from slow downs (unless the rom is hybrid 6.1 with 6.5 stuff like the one i use).
It also can do heaps of stuff the nokia can't, assuming your nokia is a series 60 or similar.
the Os can do tethering and heaps of other neat things, winmo also has got a fair range of apps, tho dated now, the variety is nice and gives you functionality, you could obtain a lot of this on a nokia symbian phone but winmo (based on wince) is just even better then symbian.
I think it all comes down to how much it will cost you to fix, I have a better phone so i cant justify spending over 50 dollars on fixing a slower older one, but to someone who doesnt have a better phone it may be quite viable to spend that to benefit the improvement over their current worse phone.
ideally, I would say just skip over it, its not truely that fast, you need at least a gigahertz phone to be fast. a HD2 or something, if you can get one like that quite cheap and in good condition, it would be worth more then spending a bit on the blackstone (touch HD).
just my opinion though
I would repair my blackstone again because i get use out of it each time its healthy even though I have something better its still handy to have, i love the audio output on it over my htc desire, but i wouldn't be spending the amount i spent on another repair screen like it did back when it was the best potential phone i could have had at the time.

Nexus One power button fix

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....

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!

Repair help?

I've searched far and wide to find a video or tutorial for my problem, but didn't find much.
My problem; my middle button (Windows key) has stopped working - it does work at times but you gotta hit her in the right spot. It does feel like there is some physical damage to the underlying components.
My question is, how would I go about solving this problem? My HTC is out of warranty as far as I know and I've found one person selling replacement keypads in the US (I live in the UK), but is the keypad the correct component to replace or should I be looking to replace whatever is underneath?
Thanks, Az.

I would rather pay money to HTC and make them repair it than buying it my self and doing myself anywayz,. it looks like its a physical problem, the button must be replaced.

If you want to, you can change the button, it's most likely it would be it the one's broken.
I deduce that you might not be too "experienced" with electronics as you were looking for a video on how to change this part or even how to open you PDA (even if I could totally wrong as there are many persons who like to have all the available info before proceeding).
Anyway, even if I haven't opened my HD2 (yet), I don't think it would be a problem, just be sure to be very careful when you open it, prepare yourself with all the necessary tools (little screwdrivers, I think you'll need a torxs T5 screwdriver, platic pliers, etc.), clean and illuminate your working area and proceed slowly without forcing anything.
To work with most of today electronics you'll need a very fine pointed soldering iron (or heavy skills in soldering, but it's better to have both) or two would be better, a magnifying lens lamp, pb free solder (even if you can use sn-pb solder with pb free solder); but all this stuff will be necessary only if you want to change the push button itself. I just saw how to take the HD2 appart and it seems like an "average" PDA disassembling, the only detail regards the final chassis disassembling, they ask to use a oven to soften three adhesive stripes, this could also be done with a good hot air rework station.
At the end, you'll have to decide if you want to change the push button or to change the whole front buttons board.
I hope this helps.
good luck

I have taken apart some many Tmous HD's, thank could do it with my eyes closed. But it is tricky. I think I'll make a video, and then post it.

You pretty much hit the nail on the head - well, I am experienced, just not any good, being into building and maintenance by trade, I'm more used to smashing and brute forcing rather than using careful precision lol.
I actually forgot about this post - what would you guys say about the volume +/- buttons? They're sticky, would I need to replace those too? And what sort of estimated parts price would I be looking at for both the buttons and a screen? I want to make sure I'm not overpaying. The screen itself isn't smashed, but the the top layer. I know it sounds like I've abused my HD2 in a bad way, but it did this to itself on a night out - I don't know how lol.
I've seen the screen part going for around £20. I have no clue on the bottom buttons or the volume keys. Would I be better off getting a dead HD2 for parts? And are there different part versions as such or are they universal?
