Can a Crack Digitizer damage LCD - LG Optimus G Pro

hello everyone,
While unrepair crack screens, can have unexpected harm to a user's fingers, this thread focus on the unexpected possible dangers that can harm the hardware LCD display quality.
I was planning to buy an Optimus G Pro with a 3 hairline (1 inch) center and corner with a 100 % percent touch response.
My plan is leave it unrepaired for maybe 2 months.
So the question is, what are possible unexpected complications or dangers that it can harm to its LCD ?
Sent from my SAMSUNG-SGH-T959 using xda app-developers app

There are no dangers. The digitizers on a phones LCD are adhered with an adhesive. The only real "danger" is trying to do the digitizer repair yourself and scratching/breaking the LCD underneath with the tools. If it makes you feel more comfortable you can always put a cheap screen protector on it until you have it repaired. Hope that helps.

HTC One V Screen replacement

I had broken my One V's Display Glass screen a month ago, the HTC authorized service center informed that the LCD as well as the display glass screen has to be replaced even though just the screen is damaged, the LCD is fine. They said that the replacement part comes bundled with LCD and the glass screen. The cost of replacement will come to Rs.5000 (~100$)
I searched ebay and found replacement glass screens available for as low as 20$.
Should I buy the replacement screen available on ebay? I have no experience in cell phone repairs and this will be risky.

IF you have no experience i suggest you go to the service centre as you COULD damage your phone further more...
Isn't the One V's LCD fused to the glass and inseparable? Those Ebay sellers are probably misleading you.
If you want to try anyway, you should have a look at http://www.youtube.com/watch?v=w96ldQq5Q2k to see what's involved.
This is what I had read... "It’s also laminated to the glass front, making for superb viewing angles" from the Verge review (http://www.theverge.com/2012/4/18/2950522/htc-one-v-review#section_4)

I have replaced countless touch screens in my life, but even I won't really think about the V because of the unibody housing. Even with proper instructions and good quality tools and materials (silica glue, alcohol for cleaning and so on...) it will be hell of a job. I personaly don't think that $100 is a high price for OEM parts replaced by the authorised service.

they are not fused together, just glued with special silica glue and tempered. It is replaceable, but it is hard enough for a pro.
If you want to maintain the good quality of the display, you will need to clean troughoutly the LCD with absolute alcohol, or any spec. cleaning liquid in a "cleen room" for not to contaminate it after cleaning, then glue them together with proper silica glue evenly troughout the whole contour of the screen. It is hard work and damn expensive, thus oem will replace the whole screen-touch screen parts.
Thanks for the opinions. I will go with replacement from service center.
Same here!
Hey. I dropped my One V from the bed today morning! :crying: It got a huge crack on the top left!
The crack is not on "the screen" but it still looks pretty awful :-( I have attached the pics. See the last pic for the crack.
What should i do? Please suggest cost-effective methods. Any help is appreciated.

if the touch and everything else still works...then live with it...or you can pay to have it repaired by HTC
I thought one V had Corning gorilla glass.
It's not supposed to break that easily wtf?
You can smash a diamond with a hammer. Like Gorilla glass, it is very hard and almost impossible to scratch, but can be easily shattered by sufficient impact shock.

I have broken my touch screen,and buy a new touch screen by TAOBAO.COM(Like ebay).And I have to face the problem:how to replace it....
My touch screen is seriously damaged,and should I do it by myself?
My idea is break the touch screen carefully to avoid damage the LCD screen,does it possible?
My first phone is touch diamond and have the same problem....Then I damaged the touch screen and the lcd screen both....I do not want it happened again...
Anyone can give my some advice?
It is too expensive for me to replace it by service centre....And some pros says that will takes $30 to help me.....
Thx
Has anyone had success(or failure) with this yet?
Look at this: http://www.youtube.com/watch?v=w96ldQq5Q2k
If you know what is going on, than try. If not then no. A pro is needed, if you want good product at the and.
just a heads up guys, a CDMA Screen will NOT work on the GSM phone
No gorilla glass for OneV

One V does not come with Corning gorilla glass.. This was discussed even in some other threads. Even if it have, gorilla glass will only be scratch-resistant and not break-resistant.
I'm getting mine fixed tomorrow as ive cracked the screen also.
The shop thats fixing it confirmed the lcd is bundled with the glass.
It's costing me £50 for the screen and £20 to fit it.
these screens seem very easy to break as my wife has cracked hers now also so I suppose the golden rule is be extra careful with these phones.
I had a wildfire a wildfire s and a desire and never cracked one of them and i'd dropped them all a lot harder than my hov ( which only fell 2ft ). I conclude its down to the raised effect of the glass.
this is because HOV doesn't come with gorilla glass
YouTube maybe???
this post had no solutions so I just opened YOUTUBE and searched for it

There is a video on YouTube decomposing and reuniting the whole machine and we were said it is hard to nicely reunite the machine.
I have thus a request, are there chemical solutions melting silica glues with no damages to the whole machine?

Apparently no, or none that can be brought off from a shelf. Cured silica based optical glue can only be dissolved with highly toxic and flammable solutions only. You can altough soften them with denaturetad alcohol or xylene, but there is a high chance you damage the display panel itself with them. Altoug I am talking about the dismantling of the touch panel and the display panel here.
The machine and the display unit (the two of them together) is just glued with standard heat activated glue, it can be softened with denaturated alcohol (which does not harms the other parts) or heat, and the the unit can be brought of from the phone (with phisical force of course). You can glue it together again with standard double sided glue tapes (2 or 1mm width) you can ebay them for. I haven't dismantled One V as of now, but I had a Desire X wich also had a unibody aluminium housing and a unified display panel, but there the whole unit was damaged, so damaging them wasn't a problem when dismantling it, and a prebuild unit was the replacement.

[Q]Screen damage

Unfortunately my beloved's screen sustained a sever damage
I would like to try and fix it by myself and need to know what do I have to replace
The device works fine
Screen glass is splintered but responds to touch quiet alright
A small yellow spot In the center
Does the yellow spot mean that the board under the glass is damaged as well ... or I can save it by replacing glass only ?
At eBay I find two options
Full LCD Display + Touch Screen Digitizer Assembly - 80 $
New Touch Screen Digitizer Glass Assembly - 30 $
Do you Know whether the parts over at Ebay are quality ... or should I not mess with it and pay full price by sending my beloved to a HTC lab ?
Grieving badly :crying: and waiting for some help
It doesn't seem to be possible to separate the glass from the LCD, without damaging LCD. No idea whether the screens you're looking at on eBay are the same as original or just compatible.
The only thing I can offer is that I replaced my screen on the desire HD and for the time effort and quality I wish I'd sent it off

Don't mess with it, my experience was with my hd2 and it was a nightmare and would of been cheaper letting htc do it, also I have read horror stories about cheap screens being sold for the one x

OK guys
I think I'll leave it for HTC even though the price will probably be a killer

Cracked Glass/Digitzer Replacement

So I, being the smooth and coordinated individual that I am, managed to drop my shiny new phone on it's face and break it in less than 24 hours after getting it. The screen underneath remains in perfect condition, so my question is this: Do I need to get an entire screen digitizer and glass assembly like this or this, or can I save $50 and just get this or this?
As long as I spend less than the $150 deductible I do not regret not getting a warranty. Thanks.
If touch recognition isn't an issue and your screens colors aren't bleeding you just need the glass
Thanks, that's good to hear. Now I just need to decide whether I'm brave enough to do it myself. I probably am not since there don't seem to be any repair guides, teardowns, or anything out there yet.
You can do it yourself, but the battery isn't removable. So you run the risk of it over heating when using a blow dryer or heat gun.
When my friend and I replaced a cracked digitizer and screen, we used a industrial heat solder gun. 1500°F was the max.
If you do it through a company, or a private party, $150 might look a lot more appealing for the warranty.

It's actually necessary to pull out the battery to get to the screen?
Sometimes. You can usually remove the digitizer without pulling anything out, but most the time the LCD screen is pretty far in the screen and can require you pull some stuff out.
I'm not a master on these things, so I'd recommend looking up videos on newer model phones having their screen replaced.
Should give you a generic idea.

I will be doing a complete disassembly guide probably around the 1st along with a guide on replacing the digitizer and the LCD display, waiting on my new phone repair kit to come in and go figure i had to order it around christmas lol so if you can wait it will be a comprehensive guide, just a warning though it is a more difficult phone to teardown seeing as the digitizer is a) fused to the LCD and b) fused to the body.

When i did a disassembly on the nexus 4 same "non removable" battery was held in by two screws, i'm suspecting that will be the case with this seeing as the nexus4 is one of the sister phones of the LGOG
I've already taken the back off my phone and you are correct the battery is held in by 2 screws, unscrew those and the battery falls right out

Awesome! Thank you so much,
Regarding screen replacement
If I'm not mistaken, which I might be, but I believe the digitizer and display are fused together....much like the iphone. So replacing the digitizer alone will be difficult enough if not impossible.
I've seen websites and eBay sellers selling just the glass and digitizer without the screen, but I seem to recall hearing something about a "gapless" display when it first got announced. Is that a marketing term or is it actually fused together? I guess I'll find out from my local repair place.
So is there a definitive answer to this yet? Mine slipped out of my pocket last night and has joined the cracked screen club.
They told me that the screen and glass are fused together the other day. :/
It's fused together, best option is to cough up the $150 and get it replaced. You will just waste your time trying to repair it and end up with something worse than a cracked screen.
The digitizer and LCD are fused together and are impossible to separate. This assembly is also then glued on to the frame, making it impossible to just pull off (unless you're good with a heat gun!). The frame is currently unavailable so your only option is to buy the $100-140 screen assembly and a heat gun to melt the glue enough to pry it off.
My suggestion is just getting a local repair shop to do it for you, it'll save you the trouble and most are charging approximately $150.00.

Replacing screen?

Just had someone bring me a Galaxy Note 2 to repair and they bought the replacement part off ebay. However all they have got is just a front piece of glass with no digitizer attached, is this correct? Normally im used to front screens having the digitizer attached or is it easy to detach from the broken old screen
Is there a guide anywhere for this?
There's a few threads on this around, but as far as I know, you need to use a heat gun to remove the glue on the digitizer.

no way mate. don't bother to anything with that cheapo. glass is always attached to the digitizer. they bought the cheapest thing they found.
i have found over the years that saving some money is not the best choice in comparison to user experience or other arising problems.
http://parts4mobiles.com/acatalog/S...-Lcd-Screen-with-Digitizer-GH97-14112A-1.html
this is cheaper than ebay which they ask for 166 pounds
Yeah, heat gun will melt the adhesive enough to separate the lcd. But its a very, very difficult process that will more likely than not end up with a damaged lcd or poor reseal.

mariosraptor is right. Glass is always sold with digitizer (it is one item). I haven't heard about clean glass without capacitive layer. You can buy either digitizer glass or complete digitizer glass with factory glued LCD module. This one's more expensive, but you have less work with replacing.
Anyway: buying only digitizer glass for this kind of phones (Note 2, S3, iPhone 4<, newer HTCs...) is waste of time and nerves. It is nearly impossible to separate LCD from digitizer. Buying complete set of digitizer & LCD is the best what you can do for your phone.
Yeah i didn't think the glass came seperate from the digitizer, i have repaired over 400 iphones and have done about 20 galaxy s2 and s3's and never have i seen just the piece of glass without a digitizer on it, i will tell the woman she needs a whole new screen, i think she did go for the cheapest option
This is actually what she ordered:
http://www.ebay.co.uk/itm/New-Gray-...s=63&clkid=5413496726471672632&_qi=RTM1319883
It obviously doesn't have flex, so it is only pure glass. I don't understand, why would any serious seller offer this kind of items.

Is Replacement of Only G3 Touch Digitizer is possible?

I have an issue with my Lg G3 LS990 touch screen digitizer glass. The glass popped up from left bottom and can see the light clearly. So, thought of replacing the glass. I saw in aliexpress that Touch screen digitizers are available. So is only glass replacement is possible in G3 ? Display is very fine. I happened to see in youtube videos that only LCD replacement is done but not Glass digitizer replacement. Could anyone clear my doubt? had anyone replaced their only glass and using it without any issues?
You can do it but it's quite difficult and there's a risk of damaging the LCD so if I were you I wouldn't even try as it requires a certain experience repairing cellphones. Your best option so far will be replacing LCD + digitizer which most likely comes as one piece
whole lcd digitizer with frame ain't that expensive at ebay, i had cracked digitizer and fastest and easiest way to fix it was just to replace whole assembly.

Actually i have already ordered the digitizer from aliexpress.com. As they are selling only digitizers, i thought it is possible to eplace only glass. So u mean to say that replacing only glass isnt possible? What are the chances of working if i only replace glass but not whole assembly?
Sent from my LGLS990 using XDA-Developers mobile app
replacing just glass is possible but it requires special tools and it's quite complicated task to do, replacing whole assembly can be done just under 10 minutes with screwdriver.
As far as i know lcd and digitizer are glued together, you need to warm that adhesive to separate those and lcd needs to be glued to new digitizer and in this phase i think you need OCA or LOCA glue and UV lamps or something like that... So at that point of the replacing glass process i tought it would be easier to just by that whole assembly

Is it not possible to replace without LOCA and UV u mentioned? Just normal procedure doesnt works? The seller is sending me all tools and sticker. Didnt they suffecient enough to replace?
Sent from my LGLS990 using XDA-Developers mobile app
I quess LOCA is liquid and OCA is sticker, same stuff different format. It is possible to do, but without good tools and enough experience i doubt it works or looks good. I have been repairing electronic equipment for years on work but i still wont try to change that digitizer at home because i don't have that kind of tools here...
if you need information about that process look samsung digitizer replace videos from youtube, phone is different but process it self ain't that much different.
