[Q] Video disassembly to repair cracked digitizer - LG Optimus Black

Hi there - I've looked all over youtube and can't see any advice on how to dis-assemble a P970 Black Optimus.
I've stripped it right down removing all the boards but can't get past the metal plate to the screen underneath. Plenty of digitizers on ebay but need to work out how to get the screen out. I know it might be taped down with 3M tape which could need some heat - but first hand experience is better than guess work.
Anyone have any suggestions or links for help please?
Thanks.

Hows it going.
I just picked up an HTC Pure (AT&T branded)
The top screen was horrible. But for the price it was a steal.
Does anyone have a step-by-step instructional on changing the digitizer for this device?
Ive found a used replacement Digitizer body for 20$ on ebay.
Any suggestions?

[Q] samsung galaxy s gt i9000 screen glass replacement

hii people i need some help here i have bought a samsung galaxy s with a broken screen glass thinking it would be cheap and easy to replace just the glass, and i have bought the glass from ebay and can tear down the phone but i dont know what to do when i get to the screen how do i seperate it and is their a touch layer under their or what and if anyone could suggest any good tutorials or pictures to help me understand then that would be great because it is not as easy as it seems lol :/ and please dont suggest that i buy a new screen all together because i do not have enough money and i might aswell buy a new phone for the price of an AMOLED lol thnx and plz feel free to PM me
You're wrong from the very beginning
The hardest part to separate in the Galaxy S is the AMOLED screen and the gorilla glass
because they are strongly attached together. It would be very hard if not impossible to separate them without damaging the AMOLED screen
i had this problem but there is help .. i for one done it the hard way and cracked the glass more on the screen very hard to do .. then picked it away with a very small metal pick . look at one of my posts its on here and trust me can be done and then it gets a bit harder putting new glass back on as one the touch dont work right but dw that can be sorted first buy a really thin screen protector then lay that on then lay the new glass over that and touch works fine .. hope this helps but there is a high level of one skill and to a real big risk of fakin up ur screen when picking away at it ..
thnx thats gave me allot more confidence and hope in doing this and succeeding thnx u have inspired me to actually attempt it and i myt aswell because if it works then iv done it the cheep option and if i dont try il never know if the cheap option is possible and achieveable and could uu post a link of your thread please so i can read it much thnx

how did you crack the gorilla glass more what tool did you use and how plz reply need help thnx
I'm in your same situation, and the solution that daleford2k10 proposes sounds great.
But I have some questions to ask you:
1) Where did u get the glass replacement?
2) What about the touch buttons (menu and back)? Because as I have seen in some disassembling videos they are strong glued. It is possible to get out (or break) the glass above them?
3) Did u tried with a hair-dryer first?
Thanks for your help

iv not tried anything yet as the hair dryer is concerned i got my glass from ebay
www (dot) ebay (dot) co (dot) uk/itm/Front-Glass-Lens-LCD-and-touch-screen-not-included-Samsung-Galaxy-S-i9000-/170739151176?pt=UK_Replacement_Parts_Tools&hash=item27c0d8b148#ht_2226wt_1270[/url]
but i dont know if you are a uk resident but you can get it from Hong Kong too and im taking it easy asin trying to get as much info as possible first to do this before i do it oh and i dont think the buttons will cause that much of a problem and anyway if they do break but the screen doesn't its still a win as the buttons would only cost abit and i have also seen some disassembly videos but none separating the glass if you have could you post a link thnx
Finally I got the glass from ebay (the same one as the guy of this post http://forum.xda-developers.com/showpost.php?p=21224865&postcount=238), but delivered from Hong Kong.
I haven't been able to find any videos of this neither... But as both jondale and devonblue4u say, I think it would be just a question of patience and being careful.
Good luck! As I think you will receive your glass first than me (it's going to take around 15 days according to the seller), please post some photos or videos once u do it.
success?
i am about to buy a SGS 1 smashed, but any of you two guys succeed in replacing the glass ONLY? i know i have just bought a dead thread back lol but sorry need to know. thanks
I remember reading somewhere a long time ago that it was done successfully once, but the person who did it had access to the glue used for sticking the screen to the glass, so he wasn't normal by any means. My suggestion? Suck it up and get both the screen and the display. The glass was not meant to be replaceable on its own.
I'm in the process of replacing mine. You can get the glass separated from the amoled using lots of patience,a heat gun, and very thin plastic of some sort. I used a variety of things including a business card, credit card and a very thin steel flat mrasuring tool. The key is heat and moving slowly. Lots of videos on youtube. when you are done there will be lots of glue on the screen, but it comes off by carefully rubbing it. Also, as crazy as it sounds wd40 gets rid of the rest. Saw this on youtube and was skeptical, but tried it and it worked. Cleaned the amoled with rubbing alcohol afterwards. I'm currently using my S with just the amoled while I wait for the new glass too arrive. Also, with the new glass, you won't put glue on the amoled, but around the outsides - again, youtube is yourfriend.
Hello guys, I have a Samsung Galaxy S GT-i9000 ...
I found some code for this machine, and place a code of the camera, and I was without a camera, now I can not go back to the camera, and some systems already installed some android to fix this error .... will someone help me?
very grateful ...: Confuso:

Raplacing the digitizer

Ok so i have a cracked digitizer...
I am going to replace it myself, however this phone is obviously not a straight forward repair.
Anyone have any personal experience replacing the digitizer on this phone? I have seen the youtube videos and read the xda.cn chinese breakdown, just looking for some personal input on the process if someone has one.
Also what will i need to rebuilt it? Do i need double sided tape etc. Thanks
80 views and no ones ever had experience with this?
i replaced it on 2 hd7 phones.
its a real pain to get it off because the glue tape they use goes all the way around, and its strong stuff.
you need to take apart the entire phone to get to the ribbon cable where the digitizer plugs in, so just look for some youtube videos of a tear down and watch carefully.
honestly the hardest part for me was getting the screen and digitizer clean of fingerprints and tiny broken glass pieces without messing up the screen, while keeping the double sided tape i put on in place and intact.
just take your time and everything will go smoothly.
-edit- yes you will need some double sided tape because when you take the digitizer off the sticky layer of the tape goes with it, the rest of the tape stays on the screen and is impossible to get off without damaging your screen so you have to apply new tape over it.
i used some thin scotch brand double sided tape and i cut it into long narrow strips with a razor using my old digitizer as a cutting board, the same width as the original tape.
Hi mate appreciate the advice in my thread on the HD7 replacement.
I managed to get the digitizer out, however on replacing the new one i have a problem..
You know the old digitizer has three plastic prongs, on the buttons at the bottom, search etc.
Am i rigth in saying they need to be transferred to the new digitizer? As i can't see how they fit on the LCD when stuck to the digitizer? It raises the digitizer a little, unless they hand off the edge of the lcd?
Thanks

Those are nothing more than spacers. I have replaced two digitizers without them. As long as you get some good 3M double sided in that area there is no problems.

um no they arent spacers...they are what directs the light to the 3 bottom keys. they are there for a reason so i recommend using them... ... now you are spot on with the 3m tape as it is the tape needed to do this whole job properly... the scotch crap is not made for this and WILL NOT HOLD UP NOR SEAL PROPERLY>>>
and for the person who said to put the tape over the old.... not a good idea... it can be removed and new should be used to replace the old..
sorry but i do this daily for a living so i do have a clue about this... just trying to help make it a successful repair and not one that ends up in my shop after the home repair failed and it damaged more than just the screen.....

[Q] Replacing digitizer

I've cracked the outer layer of glass on my optimus x2 which I assume is just the digitizer (I'm new to all this smartphone jazz but i've had alot of experience with building computers and such and i can follow instructions) and i'm guessing the cheapest way to repair this thing is to do it myself. I emailed LG asking about what they can do with it and they were asking for £20 just to look at the damn thing so i can't imagine actually doing any work on it would be cheap.
(can't post links but it was just some cheap generic one from amazon for £30)
I'm guessing something like this would do the job but I also need some special adhesive to get the LCD to stick to the digitizer am i right? I'm worried that it will not be as responsive or i'll do it wrong and i only recently dished out £250 for this so i'd like to try and do this right. I've watched a couple of videos on youtube which have helped a bit but none went right through the process so if anyone with any experience doing this could tell me about it i'd be very grateful.
its not that hard. everything just peels off when heated with a hair drier.
the digitzer should come with sticky strips which go around the outside of the lcd and stick to the out side of the digitizer.
Also try to get a digitizer with a frame already on it. otherwise youll have a little bit of a hard time trying to remove the glass from the frame, then gluing in the new one with adhesive.

Just follow this guide exactly, you should be fine man

Thanks for the reply, that's a lot of help Could you recommend any retailer that sells these? I can't work out if any of the ones i'm looking at come with the sticky strips. Would I also not need any adhesive if it comes with the frame? I'm not sure I trust myself too much with doing that either.....
I recently replaced my digitizer. I ordered a digitizer already in housing off ebay, shipped from Hong Kong. I would strongly recommend buying it with housing, as it's often difficult to completely make sure that dust does not get between the digitizer and the screen when you're using adhesive tape.
When disassemblying the o2x, I found the adhesive sticking the LCD to the digitizer frame was too strong for the LCD to come off just like that (be careful, it's quite fragile). I heated the LCD a bit using a hair dryer, to make it come of easier. This has the added effect that enough adhesive may stick to the LCD, so you don't need to replace it when placing it in the new frame.
I only added a couple of adhesive strips to the top and bottom of the new frame before mouting the LCD. That was pretty stupid, cause the extra 0.1mm between the digitizer and the LCD means that when tilting the phone ~60 degrees to the sides, I can see the backlights at the sides of the screen. Surprisingly this doesn't seem to add any noticeable backlight bleeding though, so it's not a problem at all. However, I'd suggest to try and see if the LCD sticks to the frame with the old adhesive, before using adhesive strips. And if using adhesive strips, make sure you remove all the old adhesive from the LCD, and use adhesive strips all around the frame.
The only minor things to look out for are:
- Be very careful with the LCD! It takes very little flexing before getting dead stripes/areas.
- Careful with the plastic at the USB port - it's a bit difficult to get to fit, and it's quite thin, so I figure it will break easily.
- At the top of the phone, where the digitizer (or LCD, I don't remember) cable is mounted, there's a little grey rubber-thingy - it suddenly fell off my phone, and it took embarrassingly long to figure out where and how it fits
- The small backup battery (?) in the upper left corner of the phone is glued to the frame. I used a small flat-headed screw driver to release it from the frame. Don't try and remove it by yanking the flex cable.
But all in all, replacing the digitizer with a new one (already in a frame) was a quick and easy operation.

Why didn't I think of this before.. been cracks in my display for almost a half year now.
Local repair company said it takes two weeks to fix.. I had no plans to go two weeks without my phone
Just ordered one
p990 mother board
dear friend
sorry for my eanglish i write from italy.
i need your help but before i have to explane my problems:
i've a lg optimus x2 (p990) with water demage.....
i cleaned the mother board with success..now the phone turn on and fix the phone net and it can recognize the battery charge.
but unfortunately WI-FI,BLUETOOTH AND MIC(the people who call me can't hear me) DON'T WORK, THE GPS I DON'T KNOW BECAUSE I HOPE TO RESTORE THE WII-FI AND INSTAL GOOGLE MAPS.
i'm sure that wi-fi problems come from the mother board because i have an other same device so i made a test using the good one but the mic problems persisted
my question is ,do you know wich parts i have to check and clean again?
do you know where the wii-fi component are located in the mother board?
thanks for your attention

Sorry for bringing up this old thread, but I have to ask, are all Optimus 2X digitizers the same? Don't some have different connectors or anything? Can I order any Optimus 2X digitizer for my P990? I was thinking of this digitizer, will it work?: http://www.amazon.co.uk/Digitizer-F...7BUA/ref=sr_1_1?ie=UTF8&qid=1364833172&sr=8-1
I had to replace mine recently, I read there are cheap ones where they only recognize 2 fingers instead of 5 like the genuine LG part. I ordered my digitizer from Ebay for around 18 british pound, I followed a few videos on Youtube with the disassembly, it's actually not that hard.
Keep in mind though that not all digitizers might come with glue attached or come with plastic tools, so keep a small bottle of glue and some plastic tools (credit card style plastic, knife) ready. One video recommends buying foam pads to glue around the digitizer, I didn't find that necessary, I just glued my new digitizer back onto the frame without problems. I accidentally made some glue residue onto the inside of mine, so make sure that you work very carefully
I have done this twice. It is not too hard and a lot cheaper. I follow this guide: http://www.youtube.com/watch?v=Po8hBaZt__o.
Do yourself a favour and buy a digitizer with bezel (which is a frame). The first I bought was ****ty Hong Kong digitizer, the second one good Polish(?): http://www.ebay.co.uk/sch/m.html?_nkw=p990&_sacat=0&_odkw=&_osacat=0&_armrs=1&_ssn=digitaloutlet.pl
The hardest part is not to get dust between digitizer and lcd screen - you could consider wearing gloves...
The second hardest part is not to bend bezel around usb inlet.
Good luck!
So there's no connector difference?

The connector should fit any p990. If you are in doubt email the seller.

Sorry for coming back to this rather old thread, but I have recently replaced the digitizer on my LG P990, bought on ebay shipped from Hongkong, following the video guide cited above. However the digitizer now works erratically with upper 1/4 not responding to touch, and sometimes the whole thing does not work, so I am unable to unlock the phone at all. The only thing that worried me during replacement was the thin layer of plastic film on the inner side, which teared off when removing protective layer (the film was extremely thin and fragile)-would this be the problem? Or the digitizer itself is of low quality?
Any suggestions appreciated.

Smashed screen help

Screen is very very delicate on these.
Does anyone know a place to get the screen,the waterproof stickers, and anything else I would need for this thing?
Thanks

I see couple on eBay, not sure if they'll ship to your location. Send a message to the seller first to double check the compatibility by mentioning your model number. Also make sure it's OEM (don't see Sony logo but they're probably showing a generic picture) & it comes with the adhesive. I'd also get a shatterproof screen protector this time!
http://www.ebay.com/itm/New-Black-L...-plus-E6553-/311424740690?hash=item48825c6d52
http://www.ebay.com/itm/New-LCD-Dis...53-Black-TN-/351496024978?hash=item51d6cbb392
Here's a video of the screen replacement (Z3, not Z3+ but should be similar process).
https://www.ifixit.com/Guide/Sony+Xperia+Z3+Dual+LCD+screen+Replacement/32660
You probably should not reuse the back cover adhesive (keep it clean of dust in case you have to reuse by mildly heating it. If anyone else knows the adhesive type, please chime in!
Good luck!
no fun
Doubt a screen protector would have helped. It literally gently fell 6" and shattered, the touch did not work after this.
Basically all parts you can find are fake. Those ones you posted are likely fake. The cheap one definitely is.
I got the parts needed from etrade supply. You need the front and back stickers. No stickers can be reused. You need the aux port sticker which is not available.
All the videos that show how to take it apart are misleading. They have already taken it apart and removed all the glue and stickers then put it back together. It will be way more work than it shows in the video.
In the videos it shows to remove the ear speaker DO NOT do it. If you do like I did you will need the earpiece sticker that is not available.
It does not show in the videos that a small black piece falls out when you remove the usb port/cable/board. My guess is they don't know where it go's, so they don't show you. The people that make the videos are the ones tying to sell the replacement parts.
Etrade did not have the front sticker they have a housing with the sticker on it. I got this. It is FAKE, it will not work. It is plastic the screw holes are not in the right spots. The heatpipe is fake it is just a sticker. You can not remove the screen sticker so it was a waste.
This is the fake housing http://www.etradesupply.com/sony-xperia-z3-front-housing-black.html
So have spent 300 dollar CAD. the phone is all in parts and I still need more parts. Mainly the front screen sticker.
The battery maybe wrecked because you have to pry hard to get it out because it is glued in. It is bent now. The lightest effort bent it off the start.
I have replaced many screens on other peoples non sony phones before.
Don't underestimate a screen protector, it helps and it works. Had the original z and dropped n number of times from various heights to grounds, both glass didn't even scratch or crack a bit.
