How do I replace Digitiser/Digitizer/Touchscreen overlay?

I have had my phone open a few times...
1) To replace Vario III case with Kaiser case
2) To fix faulty keyboard, had to bend some of the aluminium on the bottom of the keyboard unit.
So I know my way around inside and haven't broken anything... yet!
Anyway, my screen is very scratched so I want a new digitizer, they're significantly cheaper than a whole LCD assembly. I got one for £5, the assembly is over £30.
I did read on some thread that the digitiser WILL perish as I separate it from the LCD screen. Is this true? If so how easy is the clean up job?
Also, the official kaiser service manual shows the LCD and Digitiser held together with tape on the outside and not double sided tape or glue like the actual assembly looks like.
Has anyone done this before? Is there a decent risk of damaging the LCD itself or to be on the save side should I just buy the whole assembly?
I have the digitiser here and ready to go as long as I can get some info from someone who has tried this.
Cheers

Sorry bump.

to be honest there will be soldering involved and u need special equipment for that ribbon

look at http://rapidshare.com/files/103168855/HTC_Kaiser_Service_Manual_jas_pik.pdf
there is detailed procedure and all the tools needed, i believe the tools are basics, and i dont think they will be expensive to have, as matter of fact, i think buying a tool box is an asset.
best luck ...

Hi!
The service manual linked to does not specifically contain information about replacing the digitizer, just how to assembly it.
Do I need a certain kind of black tape to attach it? Is that the only way it is connected to the LCD itself?
Mine is also very scratched, and I would like to replace it, preferably done by myself.
Any tips?
Cheers

a good insulation tape (anti-static prefered) will do the job

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.

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.
Edit: I bought this digitizer: ebay. co. uk/itm/T-Mobile-LG-P990-Optimus-2X-Replacement-Touch-Screen-Digitizer-Frame-ZVLT338-/160656180054?pt=UK_Replacement_Parts_Tools&hash=item2567dac356 and some cheap 2mm adhesive strips like ebay. co .uk/itm/3M-Sticker-tape-Adhesive-cellphone-touch-screen-LCD-2mm-HTC-Samsung-Sony-/200710386131?pt=UK_Mobiles_Accessories_RL&hash=item2ebb4571d3#ht_1099wt_1165

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
a friend

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.

[Q] Glass Replacement

Hi guys.
I've dropped my xt1068 on a floor and the glass got cracked although the screen works perfectly (no damaged parts at all). I've buyed the replacement glass from ebay (this one http://www.ebay.com/itm/Black-Front...244?pt=LH_DefaultDomain_0&hash=item566c04b4ec ).
My question is, have anyone passed through this situation? Is there any way to replace it without damaging the screen? I heard that glass is glued to the digitalizer screen and I'm worried.
Any thoughts?

I don't think it is glued, but if it is try putting some light heat on it, not real hot though. The glass is meant to be replaced. I'm guessing you have the disassemble instructions.

Thanks. But the video shows how to replace the whole screen, I just bought the glass (which I need to replace). I've little concerned about separating glass from screen.
And the only tutorial I found is for samsung galaxy s4.

I'd give it a shot. The worst you could do is have to put it back together with the broken glass. It's a pretty straightforward job taking it apart. Just be careful with the pins on the cables you unplug.

I've also bought a uv glue to glue it better. After the process, I'll share the results.

Cracked screen

Well I finally did it. I busted the screen on my g flex. Its not bad. Just half a dozen tiny cracks. Can't feel them and can't see them with the screen on.
My question is had anyone replaced their screen yet?
And....
All I see on the web is LCD n digitizer together. I didn't damage the LCD. I only cracked the Digitizer / top layer of glass. Can I buy and /or replace just the digitizer only and not the LCD?

Only times I've seen the digitizers alone are iPhones and Samsung phones, but how on earth did you manage a crack on the flex? The angle would have to be perfect at the exact moment the planets aligned.

Had mine for 2 days and dropped it from 2 feet cracked my flex. Pretty bad too.
I replaced it shortly after. And no, they only come together.
Sent from my LG-H950 using XDA Free mobile app

I know I can't believe it broke too. I show off its durability by tossing it out in front of me on the ground. And in almost 2 years I haven't broken one yet.
That the main reason I haven't used my upgrade is I can't see buying a phone that can break when I thought I had one that wouldn't break. But looks like I'm gonna scoop up one of these. https://youtu.be/rPgPC9C3xwY

If the touch panel or the touch screen is damaged, but the images on the phone displays as usual, the touch screen panel part is damaged.
Note: replacing only the touch screen is hard to achieve, because the touch screen is integrated into the LCD screen.

Correct. Digitizer can be purchased seperate for less than $20 but is EXTREMELY difficult to replace without also destroying the poled as they are indeed fused together. You could purchase just the screen and digitizer, you'll need a heat gun, guitar pick, a bonding agent and patience. I'd recommend getting the screen, digitizer and frame already assembled (it'll just be a few dollars more) and moving all of your internals on to it. All you'll need is a micro Phillips screwdriver. It's easier, quicker and a more long term solution, not to mention it'll put your Flex back in mint condition as it's an all new housing. Total invested will be less than $100 bucks including beer. Good luck should you decide to go through with it, it's surprisingly easy.
Source: I do micro electronic repair and have replaced screens on dozens of makes/ models including the LG Flex.

I'd just buy a replacement display-itizer assembly from eBay (~$70), pry it apart and gluge it to the frame with 3m ultra thin bonding tape.
Total cost of repair, including tools (screw drivers, tape, spludger) is under $90
I've been thinking of buying a replacement myself, just in case.
Plus, there's one I've found without the LG logo, looks much cleaner.

I've separated them before. And re assembled in the restroom with the shower on high heat to create steam. Keeps down the dust. But I believe @ $62 replacing the whole thing is the way to go.

hi there. where was the flex screen parts at for $62 ? thanks

Anyone feel like making a few bucks, I have one with some burn in and would pay someone to replace my screen on my LG G Flex. Not worth it maybe at todays prices, might just buy a new one? Thoughts?

I wouldnt replace it just due to burn as it will just return. I dropped and busted mine a couple months ago and not replaced it yet lol.

yes I bought the lcd/digitizer/frame all together, its under 90 bucks, real easy to put together , sure you could get the individual parts cheaper but its too much fuss to put together.
