Hello everyone,
I am new in your community and I hope you can help me.
I am searching for manual that explane LCD touch screen (digitizer) replacing for Qtek s100 for like 5 hour in Google.com and your forum.
I try diferent key-words in search options but i couldnt fined it.
The only thing that i understand from posts, that i find, is that there is a menual describing this process, but no one know where it is.
Please, if there is such manual, give me direct link.
Or you can discribe me what do do.
I can easy take apart my phone, but i cant separate Touch Screen from LCD screen. They seems to be glue to each other or somthing.
I will value any help.
Best Regards.

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.
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

... 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.
Hi guys, i followed all the indictaions on the official videos but i think i broke something! I had an HTC hd2 with a broken digitilizer but the screen worked fine. I bought a screen+digitilzer combo and replaced it but it didnt work.
The screen does not show anything (black screen) but the backlight of it is on!
I tought maybe was a problem of that lcd so i tested the original screen (that was working) and it does the same.
What could be the problem??
Please i need help
come onn, anyone ?
please guys, anyone ??
Sounds like a defective lcd to me. I'd try an RMA asap on getting another unit before your DOA warranty (if the lcd has one) runs out.
it's not the LCD. I had a working LCD but a defective digitizer, i bought the lcd+digitizer replacement and now both screens do the same , just the backlight is on. And before i change the screens the original lcd was working fine.
Could it be because the LCD is not correctly pasted into the chassis ? i really don't know what could it be the problem. The lcd is correctly connected to the mainboard. What could i broke in the process?
Thanks connexion2005 for the help anyways, is nice to see someone finally answered hehe!

If you were not really gental with the internal parts of the phone, more presisly the ribbons that connect each part to the main board you could have cause micro cracks in the copper strips of the ribbons. Look at the closely with a magnifying. glass if possible.
today i was able to sync it literally with no idea of what i was touching. I also figured that the digitizer works , i was able it dial some numbers. The phone appears to work.
So, Backlight is on, Touch (digitizer) also works, but not showing anything on the LCD.
Could it be a mainboard problem ?? I'm trying to use logic because i don't know anything about cellphones and how do they work in terms of components.
Could it be the ribbon ? I dont think so, i have two screens and both of them do the same (backlight on but not showing anything).
I'm clueless!
Don`t panic. Calm down, watch a demolution tuturial. You probably miss smt. Good luck
But it could be a ribbon...
Hey guys,
I have a problem. A week ago I dropped my hd2 and the screen was smashed. I took it to the service and they replaced the digitizer. Now, as it turned out the lcd displays badly and the say it has to also be replaced. I know that after the drop the lcd worked fine. Now it looks like this: http://img857.imageshack.us/i/imag0001u.jpg
My question is - is this broken lcd? it has to be removed? or can I do something with it? is it the fault and they've done something wrong?
Thanks for answers.
Read this post by XDA member Facdemol, this post will help you answer your question.

Unless they just haven't connected the LCD properly (very unlikely), there's definitely a problem with it... I'm afraid I think it'll have to be replaced.
in turkey if there is a digitizer problem they change the whole screen.
Under the TMOUS warranty they will replace your phone if an issue comes up like that because it's usually just an unlucky roll of the dice if your LCD does that.
because your problem seems to occur after a mechanical shock, i would suspect 2 scenarios.
1. You have a bad connection between the display flex connector and phone's motherboad. This can either be caused by motherboard display connector failure, some small pins on that connector got busted when the phone was either dropped or once the digitizer was changed. I give pretty small chances for this to have happened.
2. If you see a phone lcd stripped down of it's housing, you will notice that on the bottom part of it (or lateral one on some displays) you can see a flex cable coming from the display's glass-like surface to the back of it. It sits pretty tight around one edge of the screen. It connects the TFT matrix to the processing part (column&row controllers) on the back of the display (or on the flex cable/phone motherboard .. ). If a phone is hit from one side, the case and display housing can press hard on this flex cable and break it, or puncture it. In this case, some of the signals needed to drive some specific areas of the tft matrix aren't getting to the matrix itself so you see some lines on the screen (plus color rendering errors). Sometimes, improper manipulation of the screen when assembling back the phone can also cause the problem.
I give more chances to this scenario.
If number 1 could be fixed by a simple phone disassemble and connector checking, number 2 will indeed require a new display as there isn't any way to service that broken flex cable.
My previous posts about display problems tried to focus on "naturally occurring" problems, not ones induced by electric/mechanical shocks. So in this case, my above scenarios will be more suited as likely suspects for your problem.
