Alright... so the other day i take my sx66 out of my pocket, only to see the touch screen cracked... the phone still works, most of the time, and you can still use like half of the screen. So i need to know, how hard is it to actually change out touch screens. Ive heard it is difficult, and would really like to know how to do it.
Thanks

We can repair the system for you. We do not have DIY kits for the TS repair though.

wow, wayyyy to expensive... you can almost buy another unit for that... i mean, i can buy the touch screen for ~$40, and do it myself. i heard it requires some soldering, and what else?

You can do it yourself. We've had people do it before. Some are successful, most end up causing more damage and have to ship it in anyway.
Here are some tips:
First, double-check the new TS. There are few different mfg of the TS. Some that we evaluated have fibers & dirt between the layers of the TS.
Be very careful with the flex cable coming off of the LCD. It runs through the slide mechanism and tears easily. You'll need to remove the LCM assembly from the top cover/slide assembly.
Use a soldering iron to desolder the TS cable from the back of the flex cable of the LCD. Use a xacto knife or something similiar to seperate the TS from the frame of the LCD. Usually the TS will shatter during this process. If you push the blade in too far, you'll scratch the top of the LCD which cannot be repaired. If you get the glue from the seal of the TS onto the LCD, you'll need to use 99.9% alcohol to clean the top of the LCD using a microfibre cloth. Having tweezers handy helps.
When you go to install the TS, start at the top and then slowly lower it onto the frame of the LCD. Do not push it all the way down. You'll probably have several bits of dust and debris that has been attracted to the TS. You'll need to have moisture free air to gently blow out the dust before pressing down and sealing the TS. We actually use grade 5 nitrogen to blow out the area.
When resoldering the cable do not apply too much heat since the mylar of the cable melts easily.
Hopefully with these tips and others on the board, you'll be successful.
thet doesnt sound hard at all. last night i already took it all apart, and didnt mess up anything. so hopefully i can get a new ts and get it back on without damaging anything. thanks so much for the info.
I got something really weird..
I have opened the unit and checked the configuration..
The old TS versus the new TS is totaly opposite?
Old 1 2 3 4
New 4 3 2 1
Pin configuration..
I manage to hook it up but it won't get pass the alignment screen.. is there a way to re-teach it?
Please help..

If it will not align, then the pins are hooked up out of order or the TS is defective.
The interesting thing, there are different touchscreens, have different pinouts. The most important thing (from my experience) is to connect pairs properly. So, you have on touchscreen top, bottom (vertical pair), left and right (horizontal pair). If you'll look at touchscreen, you'll see how your cable is wired to glass/film. At first, you definitely need to put pairs properly. vertical to vertical (on board) and horizontal to horizontal. If you'll mix up wires - you'll fail calibration procedure.
By the way: if you'll mix up top and bottom or left and right - touchscreen will work and pass calibration. Of course, calibration values in registry will be hmm... other, than usual, but touchscreen will work.
If you have multimeter, you can easily check your tuuchscreen. Horizontal pair should be 250..400 Ohm, vertical - 300..800 Ohm. If your touchscreen is not tapped, there should be infinity (not connected) resistance between pairs.
Where can you buy replacement touchscreens or housings?
ebay. search for all the different models and use worlds like broke, dead, fix repair, etc. And if you buy the right touch screen then you don't need to do any soldering. It's a really simple job. The hardest part is the disasembly, but just take your time and for god sakes tape all your screws to a white peice of paper and label them :roll: i can't tell you how many integral screws i've lost doing stuff like this.
alright, so im getting ready to buy a new TS... the SN of my phone is... HT509D615597. so what TS would i need?

Hi,
Just purchased a TP2 with a cracked digitizer. I also have the replacement. I've done a bit of research, and it looks like a ton of steps. I'm pretty confident I can do it, so all I'm really looking for is some tips. Any surprises I might see that may not have been covered in this guide? This is what I have so far:
http://translate.google.co.uk/trans...ka/htc_touch_pro2/&sl=ru&tl=en&hl=en&ie=UTF-8
how did you conclude that your digitizer is cracked?
The LCD is fine. It's the top layer of plastic that is cracked. I haven't received the phone yet, but I inspected it, and that's what I concluded. The person who sold it to me is including a replacement part, but I know I'm looking at a lengthy process to dismantle the device.
Do you have to take apart the entire phone just to change the digitizer? I thought you could just hook something underneath the corner and pry it out.
It seems like such a drag if you have to take the whole phone apart to change an exterior item.
Man you're in for a world of hurt and frustration... Easier to just purchase and replace the LCD and digitizer together...
But hey, good luck.....
have you managed to replace the digitizer only? if its such a mission why are so many people selling them on ebay? a scam maby lol?
i too am interested in your results, just now bought a cracked LCD htc touch pro 2 for $100, touching the screen works, except that the phone is stuck in head-set mode and can't seem to get out of it. also, i want to replace the lcd and use the phone myself. can you pls post your success/educational steps which you followed. also, where did you buy the replacement LCD? how much ? pls help.

Totally agree here. From what I have read you dont want to mess around with trying to pry the current digitizer off and then reapply a new one on. It's a HUGE pain in the ass. Just purchase a replacement LCD screen/digitizer combo and i's apparently super easy to swap out.
I've taken apart tons of phones, I'm currently waiting on a digitizer to replace for my TP2. If you search this forum you will find instructions how to do it.
While waiting I've been reviewing the instructions.
As always the hardest part is putting it back together.
The only thing I can recommend to you is to don't worry about replacing it. Take pictures with a digital camera as you go so you can know how to put it back together.
Hopefully I will get mine by this weekend. It is for a T-Mobile TP2 and the only shop to have one available was in Hong Kong.
Good luck.

Hi, can u post how you go with this e.g. is it easy enough to seperate the lcd and touchscreen. Maby a few pics as well if you can.
Cheers
It can be done but it requires ALOT of patience. Take it slowly and try not to leaver against the LCD in anyway. If you do break the screen when replacing it a replacement isn't expensive.
I replaced the digitizer twice. Taking the phone apart and assembling it back is difficult only when you do it for the first time. Once you know what's going on it just takes some time and precision. The REALLY tough part when replacing JUST the digitizer is putting the lcd and digitizer together without any dust or fingerprints in between. I ended up with dusting and vacuuming the room, putting some super-clean brand new plastic bags around the workplace and putting the cold shower on. Then using super-clean glass polishing microfibre cloth and anti-static glass cleaning liquid under really good lamp I managed to get both parts 100% clean and put them back together. Don't forget latex gloves (the ones that leave no marks) - fingerprints are hundred times worse than dust to get rid of. I have no idea how long did it really take but when I finished my back hurt like hell and water was dripping from the ceiling
Separating lcd and digitizer is not too hard. It was easiest when it was still attached to the bezel. I just pried it out applying easy, firm pressure and taking my time. Try not to damage the sticky layer on the edges or get it excessively dirty - it'll make your life easier later.
I hope it goes easier for you. Gud luck!
EDIT: Make sure that lcd is positioned 100% correctly (there is 1 or 2mm space to move it around). It is a very unpleasant surprise to put the phone back together just to find out that some top or bottom pixel lines are permanently invisible (The Voice of True Experience speaks here:/). And generally - keep the place around you tidy - maybe some containers for screws, parts, tools and that sort of stuff. I am not naturally anal enough to start from this point but found out in the process that this sort of job gets extremely frustrating and exhausting when you get confused, start losing parts etc.
It is major hurt! The TP2 is really not user serviceable! Anyway after reading all instructions I still screwed it up. I should have sent it in to HTC. I would not recommend changing the digitizer on your own.
Everything went well until it came to removing the LCD & replacing the digitizer. I cut the speaker cable, and the LCD just came apart. Luckily I have another LCD, looking for a speaker cable now.
has anyone found any places that sell the lcd and digitizer together for the T-Mobile TP2?
Thanks to these instructions I was able to replace the broken digitizer (glass) on my TP2. Unfortunately the Russian instructions stop short of replacing the glass.
Tools required: T5 torx mini screwdriver, letter opener, mini philips, a mini straight screwdriver and I found a very mini (1mm ) straight screwdriver handy for getthing the keyboard and screen back loose. The letter openner and two straight screwdrivers are only for prying
Here is what I did from the last spot on the Russian instructions: (yes you have to do every step)
Note: Be very careful removing the ribbon taped to the back of the LCD. You have to pry the speaker out ot the case up at the top; don't attempt to remove it by pulling on the ribbon. Once the speaker is loose (it's attached to the riboon, you are ok to remove it.
1. Take a small straight screwdriver and pry all around the LCD (metal back with handwriting on it in the last photo.) There are plastic tabs all around it centering it. You can pry gently against them. The LCD is only adhered with a small gasket around the edge of the glass. It is not glued to the screen as was posted by someone else. It comes out fairly easily.
2. Remove the black tape holding down the ribbon connected to the digitizer. I wasn't able to save the tape but not a big deal. Below the tape is one of three screws holding the buttons on. Remove those three screws.
3. Now you should be able to remove the digitizer. Go slow starting at the bottom. It is glued all around at heavily glued at the top. I had the pry the top away with small flat screwdriver and a letter opener. Go slowly and eventually it will release. At the top of the glass is the speaker for your ear. It will likely come off with the glass. Remove it and return it to the now empty case centering it in top.
4. Using gloves to prevent prints remove the protective film form your new digitizer. There is a lot of static generated when you do this so keep it away from everything for a minute while it neutralizes. Then place the digitizer in from the top, feed the ribbon through the slot and press the plastic all the way around.
5. Replace the buttons and the screws that retain them.
6. Replace the LCD; you can't screw it up the plastic tabs center the LCD. Just make sure the ribbon is at the bottom.
7. Reverse the instructions in the Russian link at the beginning of the post.
All told it took one hour the first time. I got it all together and then screen didn't light it. I had trouble reconnecting the screen ribbon during assembly so I figured the problem was there. I took the phone apart (to the end of the Russian instructions) and reinserted the screen ribbon into the connecter and then reassembled the phone. It took 10 min to disassemble and reassemble the phone the second time although I didn't have to take apart the screen.
So that's it. It cost me $22.00 for a new digitizer and $10.00 shipping, which is a lot better than a new phone if you don't have insurance and the phone looks like new. If you look very hard you can make out one tiny speck of dust under the glass but it's barely visible; much better than looking at the large V shaped crack I had before.
Hello!
I ordered (and received) a screen AND a digitizer. But there's a thin scotch tape that make the screen+digitizer (in one piece) get stick to the phone. OK, I teared it off.
But, how can I replace this scotch tape??? Much less of 1 mm thick, it seems to be made of foam...
Anyone can help me???????????
Please....
Coucou !
Is there anybody out there?

I was sent a Digitizer from Ebay (without LCD). Just for everyone elses benefit, there is no way you can remove the digitizer from the LCD Screen. It's glued down. Maybe it wasn't the case with the older ones, but mine can not be separated, no way!
Taking the phone apart is not too hard, the video instructions are pretty good, but seriously, forget trying to replace the digitizer only.
Here is the video:
http://www.youtube.com/watch?v=MrTRPTmoxpw&feature=player_embedded
Cheers, Mal.
If it has the same construction as the HD2, you can put the LCD + digitizer in the oven for 5 minutes at 50 degrees celcius. This was shown in instructions by HTC. Then you can seperate them.
Maybe, but my LCD was glued across the whole screen not just the edges. I'd suggest only buying the Digitizer/LCD combo if you want to do this yourself. If you buy both (as a single piece) the job would be pretty easy.
Last night, I went a little to crazy with drinking and woke up this morning to find that there is something (probably alcohol) between the glass and the brush metal of my phone. I looked around for a disassembling video but couldn't find one that shows how to remove the glass. Is this possible? Does anyone have any suggestions on how to remedy this?

lol... it may be more trouble than it's worth... i'm sure i can find you a disassembly guide but is the glass going to need to be seperated from the lcd? or do you need to just need to take the phone down some to get to where it is? the lcd is affixed to the glass with adhesive and separating the two and getting them back together without any problems will be pretty difficult without breaking the lcd... if its close to pure spirits it should evaporate fine... unless its beer or liqeuor...
anyways...
it will be he same as I9300:
http://www.youtube.com/watch?v=p9Nhi3vVAEg
to sum it up, it's all into one part, and when purchasing one, it's always kitted up, but i recommend against trying to get the two pieces apart...
The video doesn't show the removal of the screen. However, looking at how to remove the glass from the LCD, it doesn't seem to be worth the trouble. I'll throw it in a bowl of rice and see if its able to soak up whatever's under there.

yea that part is always sold together... for someone who breaks it, they have to buy the whole front of the phone... and from experience with similar models, the lcd is stuck to the glass with adhesive, and the backside of the lcd is stuck to the housing with even more adhesive... its very difficult to seperate the 3 without breaking something...

Well, let me try... If you changed the battery, you already know how to replace the backplate, so it shouldn't be a problem. If you want to replace the midframe/housing, that's quite a bit more work, but still doable, if you are comfortable working with heat gun or hair dryer. I would strongly recommend watching some YouTube videos on the subject (phone model doesn't matter; you just need to understand how to work with a heat gun and a suction cup). Also, finding a good disassembly guide for ZL would be useful, to make sure you follow the teardown steps properly.
Note that I personally haven't done a full ZL disassembly, but I know how it's put together, and I have done similar repairs on multiple other phones, including Xperia Z, Z1, LG G2, Galaxy S2 and others. Basically, you need to remove the backplate, then disconnect everything and remove all components accessible from the back, making sure not to damage ribbon cables in the process (some of them are very delicate). This is where a good disassembly guide comes in very handy. After that, you are left with the most difficult task: removing the display/digitizer assembly without damaging it. You need to carefully (that's the keyword here!) heat it up around the perimeter to loosen up the adhesive, and carefully pull it from the housing with a suction cup, working your way around the edge with a plastic spudger, or a guitar pick, or a similar tool. At this stage, you can quite easily break the glass, or split the LCD/digitizer "sandwich", so, again, be careful!
If you have no experience whatsoever doing this, your screen's chances of survival are quite slim. I am pretty handy with electronics and with stuff in general, and literally spent years with soldering iron in my hands. Still, my first two attempts were fudged up (the screen was already damaged in both cases, so no harm done, but lessons learned). First time, I fried the display with a heat gun. Second time, cracked the glass trying to separate it from the housing. That was enough for me to learn the tricks. So, be prepared to replace the screen, if you break it. But hey, you may very well get lucky, and do it right the first time around...
Assuming you are through the disassembly process, you will then need to put the phone back together in your new housing, using two adhesive gaskets: one for the display, and another for the backplate. I would recommend buying the proper pre-cut adhesive for your phone (check out Amazon or eBay), but you can also use a narrow high-quality double-sided tape (3M or similar), manually cut in place.
Good luck!
Tried googling up but it seemed that there are no guide for changing the housing for xperia zl.
But oh well, maybe I need to buy the lcd screen just in case I failed. But thanks! That'll boost my spirit up to do it
Hi everyone!
I bought a new display and a new fingerprint scanner. Now, on the old one the scanner was solidly glued to the screen. Does anyone have any ideas on how I should attach the new scanner to the new screen?
Like, is there thin double sides tape I could use? Just an example. On MIUI someone told me to use epoxy, would that block the ultrasonic fingerprint you think?
I attached some photo's, two are of the old scanner, still with some white display on it. it needs to be on the small glass windows in the other photo. The glass of the home-button on the old scanner is glues directly with some very thin-spread glue.
This is the new one I have:
https://www.aliexpress.com/item/New...-ID-Fingerprint-Sensor-Parts/32803906214.html
What would you think is the best way to attach a ultrasonic fingerprint scanner to a display?
Please think with me! Thank you so much
Just use some epoxy resin! You know, the one that comes in two parts, and you mix together.
Take one that hardens in 3-5 minutes, prepare only a little glue, you wont need more than an equivalent of a small coin.
Make a test first, take same quantity of each resin component and mix it gently for about 10 seconds,then apply it to something you don't care about (ex. the old broken screen, and glue the old sensor into it). Wait the required time and then check that it's nicely glued.
If you made the mix wrong it won't work well and may keep in liquid state.
Have some alcohol to clean (Alcohol for wounds works well), the epoxy cleans easily with it when it's liquid. But once it has hardened it will be a nightmare!
When you are about to glue the sensor on the new screen, apply some epoxy onto the sensor, making a uniform coating of about 0.3mm or so, no too much, but it must be a little in excess to fully fill the gap between the sensor and the screen.
I often use it to repair phones in special cases as this one, never had a problem!
I should go for UV glue, I think this is what they do on manufacturer.

If you where buying on Aliexpress why didn't you just buy one that was already glued? It costs a couple of dollars more.

Hey, did it work? I mean the epoxy surely does work, but does the sensor function properly? I would be willing to pay those 100$ for the original screen, but all of them are out of stock, and 150$ is a bit too much That means I have to go the oem screen assembly route :/
My screen died in milkwater btw.
did you solve the problem? i have to do same process but i dont know how
same here.
looking for soolution
Did you solve the problem? did you try to glue the fingerprint sensor to the new lcd? Could you please tell us about your experience, I am in the same situation
I'm gonna be trying this, but it will be a month or so till I get my new screen.

Where do all of you see screens for 100$??? Every OEM screen that I've seen on eBay runs from 50-70$ CAD so like 40-55$ USD
I looked in google and Aliexpress, I dont want an OEM screen- I want an original one, but noone sells it for a reasonable price. I found a original LCD with OEM digitizer though (40$), and thats what I went for. Just waiting for the package.
I bought the highest rated fingerprint sensor also, gonna report if it works.
@Piciu256 Tell us how is it going, how will you connect and if it works.
Could you please share the links and how long will it take for it to arrive to your house.
I can share some ideas with you.
I bought my screen assembly on Dragon Tt site, it's the "oem glass+original LCD" one, the fingerprint reader is this one: s. aliexpress. com/jemyIrQN
Should be 2 weeks tops till the LCD comes, then I'm going to use a standard 2 piece epoxy to assemble the thing, then the b7000 glue to attach the assembly to the frame.
Gonna report again after the fact if it went well.
Interested in this as well, following this topic . Just busted up my screen, the buttons and fingerprint scanner don't or barely work anymore.
Can someone recommend a good replacement screen, or is the dragon-tt the best option?
Thanks
I'm replace LCD and bought new fingerprint sensor. New sensor replce with b7000 blue, but fingerprint doesn't work.
Anybody know how to resolve this problem?
The sensor is bad or the b7000 glue is not appropriate for this operation (why you no use 2 part epoxy as sudgested?) either way you are fckd- you cannot remove the sensor without destroying it, and you probably cannot clean the surface well enough without damaging the screen to install a new sensor so no fingerprint for you.
My screen came in today, I'll report in 2 days if all works. @edit the epoxy is curing atm, its great because its so sticky- you just need to locate it in the beginning and not touch it for few hours, it makes its magic by itself- no need to anker anything down
The sensor didn't work for me either, tho that might be a case of my phone not working properly as the previous one wasn't working either.
The screen is great quality, the digitizer sticks up a little more than original though.
If you want to try yourself- use epoxy, it seems perfect for this use, the sensor is 5$ so it doesn't cost you anything
ps. Do any of you also experience this weird glitch in chrome that when I type something longish then the app takes up to 1,6GB (I believe the system doesn't grant more) RAM and freezes? (this post was enough to freeze twice and crash)
Hey guys, someone replace fingerprint and works fine? I'll paste mine What do you use for this? epoxy is safe?
thanks
