Hi,
I've replaced the digitizer and battery on my LG G2 D802. This was done after the original digitizer was cracked from a fall. Before the repair the screen and phone worked perfectly and half the digitizer was functional.
The battery was breached while attempting to disassemble the phone, so this was replaced as well.
When booting back up after the repair, the LCD is now having issues (no issues prior to digitizer replacement). The screen goes all white on boot up, and seems to be grey in it's turned off state, as opposed to the normal black colour. The phone seems to function besides the screen, and the digitizer seems work.
What do you think is wrong and how can I fix it? See pictures below.
Possible malfunctions according to myself are:
- I've read that white screens can happen when new hardware is not recognized. Maybe a factory reset will fix it?
- The connectors for the LCD screen not being tight (they seem fine to me);
- The screen got messed up from the heat or melting glue when heating the screen to peel off cracked digitizer.
I would very much appreciate your help on this issue, so thanks!
Pic 1: Screen is turned on and an all white screen is shown. Pic2: Screen is grey in its off state (looks like a 90s Nokia or a calculator). The bubble in the middle is caused by residue glue. Pic 3: G2 grey screen compared to normal black LCD off state of an iPad.
look like lcd was damage during removal of digitizer
When phone is powered off is that LCD still grey? If yes then probably its been damaged. Is there any colour problem it is definitely damaged. Also you stated that you replaced the digitizer and battery. AFAIK G2's LCD and digitizer are fused together so when you replace it will come as a unit. Maybe it was cheap clone?

He tried to do just digitizer which is a no no unless you have the correct tools. He said "- The screen got messed up from the heat or melting glue when heating the screen to peel off cracked digitizer."

Yeah now i see. That explain greyed screen. Lol. Bad choice. A set of it would be cheap and less hassle to operate. Not to mention he will got both LCD and digitizer as a new unit.

Yep, bummer!
I would recommend getting one with the LCD and Digitizer in the housing. Super easy to replace.

I didn't say that. I said it is a possible reason as to why the screen is now grey. Except for the colour it doesn't seem heat damaged. There are a bunch of videos on Youtube doing this same repair, so it's definitely not impossible. For all I know the screen might be greyed out if it's not connected to the battery. That's why I'm asking here.
Could anyone point me to a reliable supplier where I can get the LCD and digitizer as a unit without paying a fortune? I live in Europe btw.
same problem, how did you get it fixed ?

To make a long story short:
I must have somehow put too much pressure on the digitizer to create a "newton ring" which in turn would not allow me to use the touch feature of the digitizer. I sent it to HTC USA to repair it. They noticed the "newton ring" as well as the modified ROM
They would not warranty the "newton ring" and said they would not repair the Digitizer due to the fact that it had been "hacked". They would replace the Digitizer, LCD and internals for $389.00. I told them they were smoking crack.
After paying HTC $25.00 for doing nothing they sent the phone back and I went online to order a Digitizer. I paid $17.00 which included shipping and I got it within 7 days.
The HTC service manual does not have a guide on how to replace the digitizer or the LCD. They really don't want you messing with it.
It was scary and I thought I had ruined the phone when I pryed the front of the unit open. At first the sticker to the digitizer came off(black framing) and then you have to pry the digitizer(its pretty stiff) from the frame. I destroyed the thin cable that led to the backside of the LCD but the new one has one already attached so I wasn't worried about that part. The LCD with a metal base plate is attached to the back of it. You have to slowly pry off the LCD from the backside of the digitizer.
Anyways I have assembled it back and everything is working perfectly. It was doing Micro-Surgery at times.
Just wanted to share my story.
Congratulations!!

How did you attach the digitizer to the LCD? Aren't they glued together or something like that?
Because that's where my attempt went terribly wrong: Instead of getting the digitizer off my LCD, I broke my LCD... I bought a new complete screen unit because I didn't know how the LCD is attached to the digitizer!
The digitizer is semi-glued to the LCD panel which sits on the back along with the thin metal cover. The digitizer has a thin flat connector that connects to the back of the main board on the bottom. I slowly pryed off the LCD(grayish white in color) from the back of the Digitizer. It came off and I aligned it back up with the new digitizer and the glue residue left over from the LCD adhered to the rear of the new Digitizer. the tricky part is the thin connectors that attach to the mainboard. You have to get a pair of tweezers to pull it from the flat connector. When you get the digitizer you will see the new connector. Attaching that and the prying of the LCD was the hard part.
I read somewhere some guy said he broke the LCD but in truth it wasn't the LCD that he broke. He pryed apart the 3 layers of the Digitizer and thought he ruined the LCD. I thought the same thing orignally then I when the whole LCD/Digitizer was in my hand I was looking realized that the LCD was the grayish/white panel on the back. One can easily peel away the top 2 layers of the digitizer and would think that it could be the LCD they ruined.
I hope that makes sense. It was the first time I did this and I didn't see the video where someone removed the Screen. I only saw the Russian guy who didn't finish the job because he was stuck at the end. I just figured it out the hard way.
Also the T6 works but I think a t5 would be better. I only had a T6 and it did the job.
I am so glad I wore gloves or I would have had some major finger prints all over the unit

Thank you for your explanation! But I'm still not going to attempt this on my own any time soon... We'll see... Maybe I'll change my mind if my digitizer is broken or scratched...
Respect man! You mentioned that you bought digitizer for $17. Is it possible to buy mainboard for Touch HD from that place? Can you please advise where I can get it. And how much it will be?
Got to love a bit of micro-electronics DIY!
This just shows that HTC are taking people for a ride - there are a lot of people who would have just paid the price they stated. As you've only replaced the digitizer, shows they were taking the mick with the LCD and otherwise, what are these "internals" that HTC said it needed I wonder...??
Just replaced the digitizer on my HD and it took about 1.5hrs. As long as you're very careful, it's not that hard at all.
Make sure you have the Service Manual though as it was a great help.
Have you got the link for the service manual?
Ive just had to order a Digitizer as my phone has decided it doesnt want to work anymore (6 months to go on contract too ffs).
Managed to get one from a UK seller with tools for £17 so im happy.

Hi:
How did you get the digitizer separated from the LCD?
I was thinking of putting two suction cups (1 on the back of the LCD, and the other on the front of the digitizer), heating everything up for a couple of minutes with a heat gun, and then pulling them apart holding the suction cups.
Does that make sense?
Thanks.

Mine had that pearl essence look to it for a good few months before it broke, not that im sure that has anything to do with it.
Just awaiting the delivery of the digitizer and hopefully I can repair it.
yeh mine had the pearl effect for a long time prior to it dyeing
ive followed the service manual and the video of the guy who gets stuck near the end, but how do you g et the screen out of the casing to get to the digitizer?
Its one hell of atight fit and i cant see anything o bvious.
Help
Hi Guys
Sorry about the late replies - had phoneline probs!!
Assuming you followed the instructions in the Service Manual to take the rest of the phone apart, you've just gotta be VERY careful and push the screen out from the back (where the Circuit Boards where) of the plastic frame. At first, it feels like it's not budging but be patient and it WILL start to push away.
It seems to be held in with some sort of hot glue or maybe a contact sort of adhesive and I didn't try it but some heat from something like a hair dryer may make the job easier.
Many people have cracked their LCD screen during the repair but as long as you're careful not to bend the screen too much when taking it out, you'll be fine.
I peeled the 3 layers (outer glass ones and then the Digitizer itself) off the LCD whilst removing it.
Good luck - it's really not that hard. Any more questions - just ask ;-)
ive got the phone apart to the point of the service manual/video
which part of the back do you push out? doesnt look obvious as to whats attached and what isnt
Once you get to the last stage (I thinks it's the Speaker Removal) you simply push on the metal protector of the LCD from the back. You will see small holes in the plastic of the back of the frame where you can push something blunt through and push very lightly on the LCD to push it out.
If I remember correctly, at the bottom of the phone where the circuit board with the vibrator and microphone on it was sitting, there is quite a large opening with the metal backing of the LCD visible through it. I started pushing there and gently went all around the phone in the various small holes dotted around it.
As I said above, it won't feel like it's working at first but it will - just be patient and not too heavy handed!
I posted in another thread about the issue of digitizer being glued to lcd. I had more pics to show, and decided disassembled pics are useful to all! So new thread for full set! If you want more I can get more! If I get enough questions I might make a tutorial for dis assembly.

I disassembled because of a cracked digitizer.
looks like a fur or "plastic" carpet, hope you don't end up with ESD related problems
ESD as in ElectroStatic Discharge ^^
Phone still works just fine.
If anybody knows how to un-solder the digitizer away from the lcd, help would be appreciated!
New images added.
Next up:
digitizer/lcd separation
any updates?
Have you managed to fix it yet?
We all want you to succeed so we can operate on our own cracked ones! Maybe you need the "unglue" chemical - you know, like superglue has an antiglue for reversing it's stickiness. If you could find out what glue bonded it, then a specialist adhesive supplier probably knows how to reverse it.
I'm sure you'll like this (if it isn't posted here before...)

Well if they're cemented (hopefully with some hyper-glue), thats a GOOD thing. Then this will be (hopefully) my first device with NO dust under the glass.
Don't you people have insurances on your devices? Talk to the ensurance company and you will get a new device for a small excess - that is, if it's beyond repair

I'm currently on my second HD2, first suffered a hairline crack on the digitizer and it went COMPLETELY unresponsive. After getting the second, I had nothing to loose and disassembled the first. I got everthing apart up to the LCM, this module has everything (the glass digitizer, the LCD and the backlight) all cemented together. As I took the phone apart, priodically I would test that it still worked - everything except the digitizer. When I tried to separate the digitizer from the LCD and baclight I ended up tearing the layers of the LCD apart, now one layer is still glued to the digitizer and one is still glued to the backlight. I have yet to see how this can safely come apart and untill I can buy the LCD the phone is totaly screwed. I think one has to purchase an entire LCM and not just the digitizer.
For those that want to try separating the digitizer - BEWARE, noone seems to have found the secret yet! If I manage to discover something new I'll post.
Yeah. I tried the heat method to separate the digi from the LCD...
No luck
It seems it is more than the simple adhesive broken down by heat.
To get the bezel away from the LCM you can use heat to make easier, but to get the digitizer away from the LCD itself remains a mystery to me.
Anybody get any other results?
OKAY..
Pics updated again...
I was able to get the digitizer apart from the LCD, using a razor.
for separate lcd and digitizer
For separate lcd and digitizer, I used nylo fisher string... and it work good... just right my problem is how to past new one ? neopren glue ?
Honestly, I plan on just adding a dot of super glue to each corner.
I believe most phone adhesives are a sylicon based glue.
It`s almost impossible to un-solder the digitizer away from the lcd, i have succeeded a few times whit hot air and very sharp cutter, but still broke 2 screens from 5...it has to be a solution for this...anyway 3 phones from 5 its not the best rate...
had to replace my glass and digitizer, so i did. after i put my phone all back together i get this weird kind of issue with my lcd. when i startup the phone it looks just fine, but then its like a shade is pulled down most of the screen. it will change depending on the background. just sucks when the main issue is fixed, something else goes wrong. anyone have this problem or know how to fix it shoot me a line.
thanks

i tried to post pics but i am a noob and it wont let me. sorry
nevermind about not getting pictures. here they are.
Try reseating the display cable.
i had taken it all apart and back together again, and its still the same.
Did you try the old display? If the old one works, and this one doesn't, then this one is faulty.
it is the old display. it worked perfectly up until i replaced the glass and digitizer. even while my screen was cracked, i could use and see the phone just fine.
How did you get the glued down digitizer off? Did you start prying?
Oh, and you should have gotten an LCD/Digitizer combo.
i got it off by heating the edges carefully with a blowdryer and used the plastic guitar pick tool to remove the glass/digitizer from the lcd. it came off way smooth and easy.
i was thinking to myself i should have got the combo as well, but didn't have the extra 100$ now i totally regret not getting it. FACE PALM!!!

I looked again. You (somehow) broke the LCD. Look in the second photo at the top in the middle. See the dark spot?
If there is no physical damage, send it into HTC. You still might be under warranty.

I have a LG G2 VS-980. The top half of my screen was completely unresponsive to touch so I decided to open it up and take a look. The digitizer cable that sits on the glass has been peeled off. Is there any way I can replace this myself? It looks to be sitting on there with just glue.

Yes, It's hardware. My first thought was do a factory reset, but no luck. I know there are several places online to get and new digitizer or digitizer plus LCD combo, both are sold with new ribbons already connected to the digitizer. I'm just trying to find if I can reconnect the ribbons myself without having to buy a $70 and up digitizer and LCD combo. It came loose completely by itself. I've never dropped the phone or mistreated it in any way, so I'm also worried if I buy a new digitizer then the same thing will happen again. I've contacted a few places that repair smart phones but they have no idea only just doing some research myself. So now I'm here looking for some professional help.
I bought it about 9 months ago on Craigslist. I'll never do *that* again.
After I got it home, I noticed that the screen looks as if it has been replaced. A tiny bit of glue in the upper corner. Oh well. It was working fine. Or so I thought.
A few weeks ago, I started getting these strange vertical lines through the entire display. I couldn't figure out any pattern to it (time of day, temperature, etc.) It would usually go away within a few minutes.
Then today, I hit the power button to bring it out of "sleep" mode, and the screen flickered a few times... and died. I tried to power it back on; no dice. I pulled the battery and tried powering it on; no luck.
I plugged it into an AC charger and at least I saw the battery icon. I powered it on, and the screen flickered and died again.
Is this a known error or a simple fix? Do you need more information?
Sounds like a dead display, not a real common problem but it happens. You can replace the display which is not a huge deal but my concern is the glue you mention. That may make it a bit of a challenge to repair. Depending on what type, how much and where glue was put.
How much would a new display cost if I replaced it myself? How do I know it's just the display, not the digitizer or something else, etc.?
Check Ebay. Ebay is usually loaded with replacement screens/lcds. If you do buy from there make sure it is a Sprint variant of the SG4. There are suttle differences on the inside between GS4s. The lcd is the part you'll need to replace if necessary. I would advise, taking the display off first to inspect what the previous owner had done. It's entirely possible that the lcd cable ribbon is loose or not seated properly to the board.
The display will be the outer glass, digitizer and LCD all in one package. You can try to replace parts separately, but trust me it is not worth it. The outer glass is glued down to the digitizer, that is a real pita to get apart clean without damaging what is left. Then if you do manage to get it apart it may not function as well or be as durable as originally because the outer glass no longer makes contact with the whole digitizer. Think of it like a single piece of wood vs a laminate like plywood.
Granted it may not be the display (there is always a possibility it could be something else -like aliens) but most likely it will be the display. I would think of it this way- try to replace the display, if that does not work you can resell the display you just bought and you might be out $20- well worth it in my opinion.
Thanks for the info. Looks like the glass/digitizer/LCD will run me about $100, so I'm not sure it's worth it.
Does anyone have the link handy for the Galaxy S4 drivers so that I can get what I need off the phone?

I've followed instructions to take the motherboard out and put it back in. Is it difficult to ge the display off? Is the LCD cable ribbon easy to find?
