LG G3 Faulty LCD - G3 Q&A, Help & Troubleshooting

Hey All, I dropped my G3 and cracked the screen, it had big black patches on the LCD as well and the digitizer only worked on parts of the LCD. I sent to a local company for a new full front assembly. On receiving my phone back I saw that they did not replace the full front but only the LCD/digi/glass. I told them this was not what we agreed on and they said they would order the correct part and refit it. 2 weeks later and they closed up shop and disappeared off the face of the earth.
I thought I'd just live with the damaged frame as the screen worked now and my phone was back in action...
A few weeks later this started happening: https://youtu.be/CUinue0obyA
I've stripped the phone down and checked the connections to the LCD but they seem fine, the only thing that looks damaged is the metal tape over the LCD connectors, could this cause the issue, or did I just get properly shafted?
Do you think its fixable?

It seems like a software issue but I might be wrong, try flash a new kdz onto see if that works.

Broken LCD Screen, replaced it, now touch doesn't work

OK, so I dropped my phone and the LCD went out, I hooked the phone up to the laptop and the phone still works fine, even the touch screen works. ( I used My MObiler to see phone screen on the pc).
I bought a new LCD screen off of Ebay and replace it, now, the LCD screen works, but for some reason, the touch screen stopped working.
When I took the LCD apart from the touch screen, there seem to be a layer of grease of some sort between the touch screen and the LCD. I wiped it off with a lens cloth, don't know if that caused any problem.
Also there is a dark film (tinted) glued to the touch screen when looking from the back, what is that for? I looked at replacement touch screen on Ebay but none of them have the tinted film layer. I've search all over the internet for instructions but can't find any.
So my question is, what are the correct procedures for replacing the LCD screen and the touch screen (digitizer) ? Also after I installed the new LCD screen, the screen is very reflective and the glare is really bad, how do I fix that problem?
Thank you experts!!
You should have replaced both the LCD screen and the Digitizer. There are complete kits on ebay as well as instructions/tools to complete the replacement. Did you purchase the digitizer also?

I went ahead and purchased the digitizer by itself after the original stopped working. Hopefully, it will get my phone back to normal. Thanks for your reply!
in the wiki theres disassebly instructions of the device that should help you (but you probably already know that since you've already switched out the LCD)
In my experience, i have never replaced either the digitizer, or the LCD by themselves, i've always bought LCD+Digitizer and replaced them as one. Seems like the Digitizer is usually glued onto the LCD and i never wanted to mess with that.

I should have ordered the kit instead of just the LCD. What lead me to order just the LCD is when I hooked the phone to my pc and confirmedthe digitizer still worked. And since this is the first time ever I disassemble a phone, I assumed the two things were separated.
But my digitizer should come in tomorrow so I'll just have to wait and see. Thanks for the info.
where did you find a guide to take apart the TP2? I just had the unfortuante luck of smashing mine in the car door as I got in....it fell out of my pocket the exact moment i was closing the door....
My screen is shot, but other than that the device appears to work. I can power on, and try to dial after I press the hard key for the phone pad. The touch portion seems to work, but from your luck, I guess I am looking at having to replace both...
anyhow...any advice on guides and how to find the stuff on the ebay would be apperciated.
I still have 18 months of a 2 yr contract....sucks....and it sucks doubly becuase i just took the insurance off last month....grr..

Here's a photo guide of the disassembly of a Rhodium (TP2), it might give you some insight. There's also been a number of threads in this section about hardware parts and the screen/digitizer in particular, listing places where people found/ordered replacement parts.

The disassembly instructions are here: http://translate.google.co.uk/trans...ka/htc_touch_pro2/&sl=ru&tl=en&hl=en&ie=UTF-8
I did not follow those instructions since I did not want to open the back of the phone.
What i did was I tilted up the phone and used a very small screwdriver and unscrewed the two screws from an angle (it worked).
Then I pried the back of the tilting part of the phone all around to reveal the inside. Be careful not to pull too hard on the flat cable since it's still attached to the back (body) of the phone.
The LCD and touch screen are glued together (I didn't know that before). At this point I would remove the tape that is attaching the flat cable to the back of the LCD, and also lift up the clear yellow tape and detach the three connections.
The widest ribbon is from the LCD, the medium one is for the 4 hard buttons in the front, and the little one is for the touch screen.
I would suggest wearing some sort of anti-static wrist strap (I think I fried my touch screen along with the flat ribbon that is attached to the phone while trying to replace the LCD without anti-static wrist strap).
Once the whole tilting part is freed from the phone, I would carefully push the whole screen (digitizer + lcd) out from the frame, again, they are glued to the frame but can be removed fairly easy.
That's it, the install is reversed of removal and hopefully yours will work again.
Like I said, I think I fried my flat ribbon so after replacing the Digitizer (it came in today), the touch screen still doesn't work, so now I'm looking for that part, I'd appreciate a link to it if anybody knows where to get one.
Oh, and for the parts, just do a search on ebay for "touch pro 2 lcd" or touch pro 2 lcd + digitizer"
Gook luck with your phone!
What tape to use to stick digitizer back to inner bezel/chassis?
Hi - i got as far as trying to replace my Digitizer only to find that the LCD was stuck to it too. So as clever as i am (not) - i tried to remove the LCD off the digitizer - but that just ended up cracking it.
So i'm in the process of ordering a LCD with the digitizer - pre-stuck together (i hope!) - but my question is:
When i removed the digitizer off the front bezel, there was this spongy sort of double sided tape... i assume it was used for a reason and not just any ordinary double sided tape (presumably to allow a bit of leway between the digitizer and the bezel when pressure is applied to the touch screen)...
Any thoughts on what sort of tape this is? - here's some photos of my digitizer and the bezel:
zedii.co.uk/DSC_0002.JPG
^some of that tape is left on the digitizer... it's the black spongy stuff...
zedii.co.uk/DSC_0003.JPG
^i cleaned (removed residue of sticky tape) in the inner part of the bezel where the digitizer would stick...
Any specific tape to use that anyone knows of?

I wish you had asked before you ordered the digitizer + LCD, since I ordered mine separately, and they seem to both working ok. The digitizer does not have to be glued to the LCD. But anyway, I just used plain old Gel superglue to glue the digitizer to the bezel. I used Gel superglue so it won't run into the electronics beneath. Things seems to work just fine now.
One thing to consider when you crack open the whole phone though. Be careful not to loose any part from within the phone, because apparently, I lost something, now my accelerometer doesn't work, and my screen doesn't rotate when you slide out the keyboard. Hope it works out for you!

Thanks for the advice adp9626! Well in summary I think I've just been messing about too much and being stupid really.
In the end, I managed to just remove the top part of the screen without actually having to break into the bottom section of the phone.
I was a bit concerned about the whole sticking of the LCD to the Digitizer part. I actually did purchase them separately, however I was not sure what kind of glue was used to stick them both together - as I recall it was a nightmare to try and remove the LCD off the old Digitizer.
So I returned both separate parts (got a full refund as I didn't use them) - and now I am looking to purchase both parts stuck together.
I'm waiting on the guy on eBay to confirm that they are both stuck together. I'm also thinking of using double sided sticky tape to stick the Digitizer back to the inner bezel...
So that's the final plan! I've been a bit silly in rushing with ordering parts etc. but I just want to be on the safe side now - well - at least with the LCD stuck to the Digitizer part.
I will take your advice on the gel superglue if the double sided sticky tape doesn't prove it's stickyness!
Thanks
Zayd.
Can anyone help me find the lcd screen and digitizer as a single unit for Sprint? Everyone I find states not for CDMA.
Thanks
Anyone ??? I spent an hour on google and still came up with no leads.

I ordered one from this guy and it works great. it comes with the entire top half of the phone and the keyboard. There is only one left so you may want to hurry. Link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=270583335455&Category=20336&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2
Edit: I wanted to add that they're are slightly used so there will be scratches. The one i received is a little more scratched than my original then again the scratches aren't noticeable when the back light is on and you're getting a working screen.
Just my experience, I had a faulty LCD, digitizer was OK. Bought a replacement LCD off ebay, delivered from China but only cost me £20 inc delivery. Arrived with tools as well (T5, T6, philiips, and pry tool). Followed a couple of disassembly instructions online, took me a while to get all apart but managed it. None of the instructions online go through actually taking the screen out, I thought I'd messed it up as I took the back half of the LCD off and left the front bit on, and I couldnt get it off at first. I ended up using a very sharp scalpel to slide between the LCD and digitizer and got them apart eventually, as I didnt realise that they were glued.
Anyway, I just placed the screen on, no glue as there is a ring of sticky tape around the back of the digitizer which holds the screen in. Connected everything back in the end and its working fine. Only prob is I think I damaged the power/standby button, so be careful when around this area.
Touch Screen not responding after replacement
Recently, I replaced a glass screen on a SGH-M919 Galaxy S4. Previously, during the process of cleaning the glue residues off the LCD screen; I rubbed it with rubbing alcohol and it removed a small streak of the adhesive glue off left side of LCD screen and bottom right corner. After installed the new glass screen, I noticed a few spots of the glass screen wasn't sticking onto the sticky layer. So it looked like it has big air bubble between the glass screen and LCD. And I could see the rubbed off streak on the LCD screen. Everything worked fine with the new glass screen, with the exception of seeing the streak and bottom right corner rubbed off.
A few days ago, I had a table clock fell on top of the phone and broke a piece of glass. Nothing happened to the LCD screen and still functional 100%. So I got a replacement glass screen - the same as the first time replacement. With noticing of the rubbed off streak and corner of the adhesive layer on the LCD screen - I decided to rub off all of the adhesive layer from the LCD. I sprayed some Goof Off liquid on the adhesive layer and left it over night. Next morning I continued scraping off the glue with a small plastic card. Cleaned off all glue residues and examined the LCD screen for any scratches or damage. There was none. Re-installed new glass screen - but now the touch screen does not respond to the touching on the icons. Only the Home, Menu & Back touch button work. I was baffled after this.
Could it be that because I left some the Goof Off liquid on top of the LCD screen over night and it might have leaked to the other side and shorted out something? I saw a few forums that suggested a Factory Reset. I did that - but still didn't work. Please advise on what I need to do to fix this problem.
Thank you in advance for the advise or suggestion.
So you know that these are the TP2 forums, and no one has used this thread in the last 3 years....right?
LCD digitizer replacement.. now black screen
I saw the for replacing the LCD-digitizer of my nexus 4 phone, and followed the steps carefully. After I placed the battery, I checked to see if the phone turns ON and the display is working before I complete the last step of putting the back coverplate. I successfully switched it ON, saw a perfectly working screen, and browsed through my apps. To complete the assembly, I put the back cover by gently pressing the frame along the edges, but suddenly I saw some yellow green lines in the middle of the screen. I switched it off and again switched in ON, but now the entire screen had light with no display.
To fix this, I tried again checking all connections but no luck. What could be the reason for the sudden loss of display when it worked perfectly fine moments ago? Is there a possibility that I damaged the LCD while putting the back cover on the phone?
I am also not sure about one of the ribbon connectors of the digitizer. There are 2 big ones which are prominent and has ports to connect. However, there is a little third one which also has to come through the gap but doesn’t connect anywhere. Has anyone also experienced this while replacing the screen? Any help will be appreciated.

Glitchy Digitizer simple fix

Having used my atrix for over a year now and the more scratches i get on my screen the more unresponsive the screen becomes.. couple that with oily/dirty hands and the screen response just go crazy all the time.
Everytime that happens I notice i get better response after wiping the screen clean and toggling the sleep switch.
Then i tried installing one of those matte screen protector around $2.- on wher i am, problem solved, no more glitchy touch screen response
Sent from my MB860
Wish it was that simple. The plain fact of the matter is.. Motorola screwed up and put in a low grade digitizer (2 point multi touch) with bad manufacturing process meaning that most Atrix out there will have problems with connections between the mainboard and digitizer causing glitches, problems with sensing and the capacitance buttons not working.
The atrix digitizer is great coupled with the fact custom roms here make the phone support 5 touch.
Atrix digitizer can go up to 8 but gets buggy.
I had touch issues only after having a broken digitizer (dropped it) for 3months.
And yea I noticed for awhile now turning off screen resets touch.
Your screen protectors adhesive probably sealed the scratches temporarily which has been linked to the issue that and stops your greasy fingers tampering with it.
Sent from Moto Atrix 4g on Neutrino 2.91
Actually, a tech, told me that the Atrix has a factory problem, and its not a bad production of the digitizer, its a fault with the Motherboard, causing it to damage the digitizer. Thats why it gets fixed when you put your phone to sleep, because its the board's fault, not digitizer's. Sooner or later, the board will cause a dead stripe on the digitizer, with no fix available except for replace the digitizer, and then if you do, after a couple of months, it will damage the new digitizer. At my local repair shop, they won't carry that digitizer anymore because when they used to, customers that fixed their Atrix would come back with a dead stripe and say that they sold a bad/low quality product, but the truth is that its not the digitizer fault.
So you are telling us that when the first digitizer issue appear we should seriously think about replacing the whole phone instead repairing it? (Obviously if warranty is void)
Yes, make sure to carry the insurance on atrix first gen models. They are all faulty. I had the problem with the digitizer/mobo that developed into the lines where nothing would be touch sensitive on the line. Our was like a break in the middle of the screen and a multi touch test app showed the phone thought two fingers were being used if you tried to Swype on the line or if you Swyped across the line it would drop you touch like you lifted your finger at the line. This made the phone touch screen useless and the insurance sent me atrix 2 as a replacement.

Both are correct.
Non reinforced mini flex ribbon on a flimsy connection mounted on another connection. Many points of failure. However a fresh oem digitizer, good repair, dab of silicone, and not dropping your phone can fix most of the issues before they happen.

I've replaced my digitizer since I bought it broken. I don't seem to have the same issues so I agree with the last comment.
I have two motorola atrix and both have fantastic touch.. One I used with broken digitizer for over a year without any issues whatsoever. Recently replaced the digitizer on the broken one, and still going strong.

[Q] Screen Repair - Motherboard doesn't fit right

It looks like I should have done a little more research!
I have a Sprint Galaxy S3 and I dropped it on pavement and cracked a little bit of the corner of my screen. This is where I should have said "okay, the touch screen works, just don't mess with it any more because you know how this ends."
But I didn't... I got replacement glass first and totally screwed up that repair and left the phone in worse shape than it started. Now with the LCD and digitizer it became a slightly more expensive repair but still something I thought I could handle.
So I bought a whole LCD assembly off ebay and installed it with few problems. I bought a Samsung Galaxy S3 R530 Metro LCD Screen Touch Digitizer Frame. I stripped my phone down, moved all of the parts to the new frame and started to install the motherboard. Then's when my problems begin...
The new frame has a slightly different placement of the motherboard screw and doesn't seem to fit quite right in line with the power button. Everything else is fine and fits just right, it's just that something isn't fitting quite right. Any suggestions?
Also, my home button doesn't work any more (that's the only thing, though, so it's still a vaguely successful repair).
It sounds like I should have done some more research and I would have found that a black frame can't possibly work fully for a Sprint phone because Sprint S3s are unique for whatever reason. I'm just hoping maybe someone has a solution? A part of the frame to file down or other suggestion?
At this point I would suggest taking it somewhere to be repaired properly. Especially if you are not comfortable with the process.

Weird blob under screen, also some dust

I received my G Pro back in May sometime off of eBay, and I believe it was refurbished, but I don't quite remember exactly. A little while after first getting it, I noticed a little blob under the digitizer of the device, not on top. I have no screen protector on this device, so that wouldn't of caused it. At the same time, I noticed that dust somehow sneaked it's way under the screen as well. I'm wondering as to how this happened, but I think dust snuck through the earpiece. I'm not sure what the cause of this mysterious "blob" is, but that could be because the digitizer is separating from the LCD screen. Any help on this? I cannot provide pictures because I am new here, so no outside links, and the files are too large to post.
I do know that in a galaxy phone, the screen is adhered to the glass. If you replace just the glass, you can't replace the "glue" that was between the screen and glass. If the GPro is also designed like this, then you could experience the symptoms you're experiencing. To remedy this, you could attempt to lift the screen up (do not force). If it comes up easily, you could attempt to clean under it with some alcohol and soft lint free cloth. Then perhaps place some adhesive around the edges that are allowing in the dust. Good luck.
The digitizer is not removable on the G Pro, at least that's what a repair representative told me. He told me the only way to fix this is to have the device completely replaced, which is impossible for me.
the digitizer and screen are not glues together on the G Pro! I have changed my touchscreen/digitizer and they are two desperate pieces. I got dust under my screen a month after I changed my digitizer. ! the area along the sides of the screen for the adhesive stripes is very narrow! if I had o guess you adhesive slipped or was not sealed correctly from the factory or something and now u r getting dust under your screen.
Okay, I guess I will be returning the device after all. I don't really have any other option.

What "refurbished" means on eBay I understand to be kind of broad. It could mean LG refurbished a phone, or a seller bought a broken phone and fixed it thus "refurbished."
The screen issue might be a poor repair job.
I will be sending the phone out tomorrow. Does anyone know the typical turnaround for LG repairs?

Note 4 Repair Issues

I had my note 4 screen assembly replaced after I dropped it. However, the screen is no longer completely secured in the phone. The screen pushes into the frame if I place pressure on the screen and I can get my finger under the edge of the assembly on the top left corner. The home button is also loose, but gets tight like it should be if I hold the screen down. This is an annoying issue and I've recently noticed that dust is getting inside the phone, which I'm worried will cause hardware damage. The front camera is already blurry and cloudy from dust getting inside. If I take the screen off and apply new adhesive, will the screen sit in the frame like it should or is it impossible to restore the feel on a phone with a screen replacement to what it was like from the factory? I hope you hear from you guys, and thanks in advance.
I would take it to a local Sprint service and repair location (or where ever you got your screen replacement). They should be able to reseat your screen in the housing and clean your camera right up. In terms of applying new adhesive, you shouldn't really need to. The 15 some odd screws on the back should take care of it. Source: I'm a S&R Technician
Thanks for the help! My problem is that I'm hesitant to return to the shop where I got the screen replaced, because when they originally replaced it I was unsatisfied with how it fit so I went back and had them do some more work. It was alright at first, but it began to get steadily worse in a fairly short amount of time. So I'm a little cautious of going back there to ask them to do more work. If I asked them to reseat the screen assembly, do you think it would help? Also, is it possible to return to an almost-factory feel with a replaced screen or do I need to accept that the assembly will never be quite as tight as it originally was?
Similar issue
I had a similar issue and I took it back to sprint which they fixed regardless of my device being rooted.
Did you have the screen replaced before you took it to sprint, or was the screen loose from the factory?
you can find the replace guide at ifixit, I don't leave the link,you can google it.
If you want to buy original LCD screen ,you can go to the HCQS.
