Hi all, I got an i9300, it has the digitizer broken and I need to replace it.
The problem is, here, in Venezuela, the UV glue and the UV lamps are too much expensive... due a pathetic government.
Anyways I need to fix the phone, and for that, I need to replace the digitizer but without the UV glue and UV lamps...
I know there is the double-sided tape but it leave a space between LCD and digitizer, so I don't like it, and... the tape is too expensive also.
I'm trying to find a cheap glue replacement, but I don't know if what I've found untill now would work or destroy my LCD...
So far, I've found a transparent glue, which has the following components:
1) Polyvinyl acetate.
2) Alcohols.
3) Special solvents.
It also says that it has no water.
The thing is that I don't know if this glue would be too abrasive with the LCD and may damage it in some way.
AFAIK, the LCDs has polyvinyl acetate on its components... but as I said, I don't know how this would react with the glue...
Somebody here can give me a hint? should I try it?...
When the glue I've found gets dry, just gets cristallized and over 60ºC it can be easyly removed.
I wouldnt mess with and unknown glue or adhesive that is not meant for this type o job. I would seriously recommend considering the double sided tape. Its a perfect fit and works perfectly.

I see, well finally, I've ruined the digitizer behind the pieces of glass... and the LCD with it, so, I must buy a new whole screen.
Warning: Do the replacement with extremely patience... do not pass the 200ºC and be extremely carefully.

I am about to replace my Digitizer and LCD on my Touch Pro.
I have purchased both parts seperately but there is no gasket no stick the 2 together.
I have read many threads on here and other places but cannot find an answer to my question.
Where can i get a replacement gasket or what has other people used, would double sided tape be ok or should it be something thicker? Maybe a foam double sided tape.
Any suggestions from somebody who has any experience in changing digitizer and lcd.
The rest of it looks no problem i have plenty of experience in soldering and am more than compentent enough to dismantle the phone its just i want to have all the things i will need ready before i start rather than take it all apart only to find i need to get something else.
Many thanks.
Has anyone seen a good take apart/repair guide for the Inspire4G. Just got digitizer replacement and cannot for the life of me figure out how to attach the ribbon cable without totally disassembling the phone. Hoping to avoid this.
If this is the wrong forum, please direct me to a better one rather than flaming me.
Thanks
Fairly certain that ifixit.com has a good teardown.
Sent from my SGH-T959 using XDA App
Thanks for the tip, but I find nothing for the DesireHD/Inspire4G there other than a total disassemble for the HD that I've already seen, but really did not help me. I just need to change to touch screen. I appreciate the try though.
Got it apart. And kinda back together. Apparently it is not a good idea to reuse the double sided tape that holds the LCD to the motherboard and the digitizer to the LCD. At least the phone works. Now, must order some proper adhesive tape and redo the whole thing.... Took me about 6 hours for whole breakdown and rebuild. Doesn't really seem to fit back together all that well though. Maybe I'll videotape my next breakdown.
Couple of questions as my phone is in need of a new digitizer too.
Did you have any other adhesive tapes in the process?
What did you use to cut the tape that held the LCD together after you baked it?
Does the phone mostly feel the same now that you have it back together, or does it feel flimsy now?
I'm disappointed that it's this difficult to replace the digitizer.

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

Thanks for the heads up... Where exactly do you recommend putting the tape? Does it just go on the black edges of the digitizer, or does it actually go on the surface of the LCD? Sorry if that's a noob question, but I haven't gotten the glass off and I want to make sure I have enough adhesive tape from the Ebay Vendor. Did you have any issues with reusing the mylar?
Sorry for the 1000 questions, I really don't want to shell out off contract prices for another phone...
Mylars were all reusable if removed carefully. I photographed every step so I would know what to put back where. Still waiting for my tape from Repairs Universe. The biggest two culprits are:
1] Tape holding back of LCD to the silver chassis frame and
2] Tape holding SIM FPC to the main board.
You might also tape the PCB cover to the upper board, mine was loose after rebuild.
That I believe that is it for the major tape requirements. Of course the digitizer needs to be taped to the LCD. I'm curious, though, the tape framing the LCD holding the digitizer seemed to have some thickness to it. Almost like foam rubber, quite thin, but thicker than regular cellophane tape.
Good luck. Let me know if you have any tips after your attempt.
Got the tape. Retried to rebuild with new OEM tape. Same result. The phone when completed expands like an accordion. The digitizer/LCD assembly does not stay stick to whatever is under it. I know when to admit defeat. Looks like I'm shelling out 500 for another phone. At least I have spare parts!
yeah i was going to do my screen myself till i seen the tear down & then called afew places around here that does screen replacements and said NO we won't touch the Inspire, i spent the money and let HTC fix it. was worth it they replaced the whole shell not just the screen ... IE lcd / digitizer / Outer case that was scratched and dented... basically a new phone with the guts out of my phone
I attempted to do this and let me just say that I too now have spare parts. I purchased a phone off of ebay. I didn't realize the no contract price went up to around 500.00 I should have gone directly to HTC. Live and learn...
I will be in possession of an HTC Inspire for testing purposes that also has a cracked screen. Not sure how bad it is but I was planning on just replacing the display for learning purposes. However it seems that it may not be worth the time spent.
If I do decide to give it a go I'll post my results here. First thing is to acquire new tape. Did you all purchase it locally or did you buy the adhesive online?
YouTube has lots of videos. Best to watch a few a see the best way. If you are scared to break it best you send it in for repair instead. Get a digitizer and screen combo.
So it's all about a Sensation with a defective digitizer. There are countless videos, DIYs, forums posts and blog articles on how to take the phone apart and to separate the digitizer form the screen. However, there is nothing on how to glue the new digitizer back in place. The options I've seen so far are:
1. Use 3M 2mm tape
2. Use what's left of the original glue (reheat and try to make it adhere to the new digitizer)
3. Use super glue
I live in Germany and it turns out that it's almost impossible to find 3M 2mm tape out here. So, could I just use any available type of double-sided tape and just cut it in 2mm stripes? What's the thickness of this 3M tape (need to know so that I can find a proper alternative).
However, the bigger question is, which of the three options mentioned above is the best? I guess that trying to make it work with the old adhesive leftovers is the worst thing to do, but is 3M (or equivalent) tape better than super glue? I mean, it's important that no dust comes through between the digitizer glass and the lcd screen... and that the newly fitted digitizer withstands the influence of high and low temperatures (hot sun in the summer, cold ice in the winter).
So, what would you say is best? I've never done this before, so I guess you have much more experience than I do...
Thanks
PS. Please excuse the typo in the thread title

Its not quite the same but I had this problem when replacing a LCD screen on a nintendo ds lite (bottom touch screen). I just went with the double sided sticky tape as I felt I could be far more accurate with it compared to super glue. I just cut it into the sizes I needed with a sharp knife and fitted it to the digitizer And then to the LCD. I have had no issues with it so far, its not slid or anything but then again it is housed in casing... if I was you I would try the tape first and if it seems unreliable try for the glue, just make sure you don't miss as it will muck up the digitizer if its no placed right I believe.
Good luck
Tapped out from my sexy nexus 7
I'd also say that the double sided sticky tape is probably the best thing to try out.. However, I'd like to know how thick the tape is. It should be thick enough to make the glas digitizer stick and also as thin as possible so that the new screen isn't appear to be higher than the old one...
I was trying to change digitizer to my tf300 by following this video http://www.youtube.com/watch?v=3_JRLd7lPv8 .The video is really bad, considering that this guy will show you a tf300 that has been opened before or something, because its very easy for him to do certain things, that i found very hard,and had to use other techniques.For example, i had really hard time separating the old digitizer and the plastic frame. In order to separate these two parts, i used some heat blowing gun (professional one) which turned to be very effective separating the digitizer from the plastic frame, but the plastic got wraped (as you can see in pic). Also, i don't have an adhesive tape or glue in order to stick the new digitizer to the frame so i m unable to stick the new digitizer to the frame.

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

It's the front plastic bezel. Sometimes it's available used on Ebay. Best place to inquire would be Asus Parts located somewhere in Europe. I wouldn't try what you're thinking of doing unless you can straighten it again using the broken digitizer, as the screen is extremely brittle and the slightest pressure might crack it.
hi
i want to know if only the exterior glass of nexus 5 can be replaced. My phone has a cracked screen but the touch response, colors etc everything works fine so only the outer glass (gorilla glass?) is damaged. I want to know if only that can be replaced as LG ask around 150$ to replace the whole component.
can i order this? is this possible?

Thanks
Bump??
im pretty sure they are fused together and if you replace 1, you replace both.
Unfortunately you will have to replace the whole thing. When my screen broke It was functional completely aside from the proximity sensor (due to shattered glass). I tried taking it apart afterwards to no avail.
Well, you'll maybe be able to replace only the touch screen (without the LCD) but it wwill not be easy has you'll probably need to heat it to be able to remove the glue, etc.
Probably better to buy a lcd + touch screen :/
ohh
so the ebay item i linked is completely useless?
Thanks for your help guys
It's not impossible to try and replace only the glass. A friend of mine has done this with his galaxy note, which also has a glued screen+digitizer+glass assembly. However, the replacement glass is pretty bad and reflective and dust has started gathering beneath it. The touchscreen was also affected: some areas don't respond so well anymore.
I've replaced just the glass on a different phone. It's the biggest pain ever. You'd have to separate the glass via a heat gun, while trying not to break the digitizer. Then remove the glue. Then adhere the new glass to the digitizer with loca adhesive. Loca is hard to deal with, bubbles, and can get into other components ruining them. It must be cured with a uv light. And even if you can pull it off, no way will it be 100%. Strange glares and whatnot. Some try to do it with double sided tape, but that leaves a gap between the glass and digitizer, which causes strange touch responses or it'll be totally unresponsive. And be prone to break the glass easily without loca. Trust me pay the $150 and let lg replace the whole assembly.

It's too bad it's like this. Probably the most likely thing to break on a phone and they make it so difficult to fix and compared to the price of the phone, expensive to fix. Certain things should just be easily fixable. Oh well, such is life.
