Disassembling the screen - LG Optimus Black

There is dust under the screen of my OB (I think between the digitizer and the touchscreen)
Is it complicated to disassemble it? should it be done by me or by technicians?
It's really frustrating to look at the OB and see everything through a lot of dust that can't be cleaned because it's inside

This as already been discussed.
You should take the phone to a certified service center to keep it in warranty.

Advice from someone who has disassembled their Kaiser?

This question is directed to those who have taken apart their Kaiser, and specifically screen the screen assembly. I've got water issues and the screen is broke now. Here's the story. I might get some outrageous warranty charges.
I installed the InvisiShield (www.shieldzone.com) on my phone. Essentially it's a screen protector that is indestructible. It practically is, but unfortunately it destroyed my phone. To install it you have to spray this liquid on the back of the 'shield' and apply it to your phone, using a squeegee to get the bubbles out. It went pretty well, and I was happy with the results, but 3 days later my screen stopped working.
Everything is washed out, and it looks like water got inside the LCD somehow. For instance, colors streak across the LCD in fonts, etc.
I called ATT and they are mailing a replacement, and I'll be expected to send this phone back. They said if the return phone has damage that would void warranty (water damage, etc) I'll be prorated $400 on my next bill.
Over the phone the customer representative had me remove the battery and check one of the water damage pads to make sure it was white. It is.
For those who have seen internal phone assembly, is there any of these directly by the screen that will pick up moisture?
As far as ATT knows, the phone LCD suddenly stopped working. I'll get a replacement and /hopefully/ theres not a moisture pad right next to the LCD assembly. Anyone know?
Damn, hate those broken screen story's. Scars the **** out of me.

I dont know but man I hope that there isn't. Have you tried contacting invisishield? Never mind, b/c they'll blame you. Most applicators like that use alcohol to evaporate the remaining moisture that's left. My friend applied it to his, and he used very little liquid(scared), so GOOD LUCK!! I MEAN IT
Tough break, sounds dangerous to pour liquid on the screen though !
On a related matter has anyone seen pics of a Kaiser pulled apart ? Still wondering where the GPS antenna is located !
Yeah, I hope I don't get shafted.
I love the invisibleshield, and I put one on my $1,500 DSLR camera screen, but since the Kaiser screen is recessed a bit, when you squeegee the solution out from under the screen, it cannot be wiped away. It just gets pushed out between the phone's body bezel, and the screen glass -- right in to the phone. With my DSLR camera, the screen is flush with the body, so when squeegee'd I could quickly wipe the water/alcohol away.
Contacting Invisibleshield got me:
Our liability does not extend beyond our product. The lifetime warranty only covers the replacement of the invisibleSHIELD and NOT a warranty for the device the shield is protecting.

If ATT charges me the $400 if they find out, I guess I'll pay it. It's my fault, but by extension of invisibleshield. Guess I'll learn not to use that product on anything that has a recessed screen. I was thinking of buying an invisible shield for my laptop as well, but it's screen is slightly recessed like the kaiser, so you can forget me doing that!

That was why I bought the 'best screen shield on the market' for scratches (invisibleshield). Coincidentally that was the demise of my phone. I also purchased a steel case that basically would let me sit on my phone (uncomfortably) if i wanted. The desire to protect my phone, did the opposite in my case.
Wow what a horror story. Thanks for sharing with us - may prevent another phone from dying.
Wondering if you remove the battery and not using for a few days until the water dries out before turning it on?

Could be, zcink. The replacement phone is on it's way. I can remove the battery during this time it takes for the replacement to come and see what happens. Unfortunately, I think one of the following has happened:
1) Water seeped between the LCD protetcive glass, and the LCD itself, and somehow soaked in to the LCD causing mini shorts -- thus resulting in kludged text.
2) Water seeped to the phone's connecting cable where the screen input is, dried on the wires, thus creating a short -- destroying the signal.
Either way, when the liquid dry's, the mineral deposits causing the short will still exist, still causing a short. For both, repair requires disassembly, voiding my warranty. I could buy a new replacement screen from the China place for about $100, but if ATT /might/ replace it without screwing me, I'll take the chance. Just wanted to know what my chances /were/ them finding out it's got water in it.
I guess the moral is.
Don't buy from InvisibleShield, unless you use a SPARING amount of spray they they include. They include a huge bottle, and I used 2 sprays worth applied to my shield. This created enough excess to be squeegeed right into my phones body. The phone worked great for a few days, until one day at work, while I was using it -- BAM -- the screen was dead.
There isn't the water dectector there, but I'm pretty sure the technicians would notice the damaged screen.
I know those screen protectors, used them for alot of things. Using one right now actully. Its the one you wash with soap and warm water, and just let it dry, it have a static adhesive to the the scree.
I see. yeah hopefully the ATT tech will be lazy and just grant you the warranty without investigating. just play dumb. If they charge you the $400 call them up and threaten to switch to T-Mobile.
My phone died and T-Mobile was going to do nothing until I threatened to switch to ATT, then they replaced it.
I seriously doubt that they will be able to tell unless you really soaked it, next time use a dry screen protector, they work just fine, no bubbles. The only moisture sensor is on the battery, and if it was a tiny amount of moisture, there's likely no signs in the screen assembly. AT&T isn't likely going to dissect the screen to check.

Hadn't heard of that screen protector before, guess it would work well on an HTC Touch, not sure how the "full body" version works though!

Amazing find. Thanks!
It appears to me that the screen itself is it's own modular unit. Meaning, after phone disassembly, you'd have to disassemble the actual screen itself. Further, there is no moisture indicators directly by the assembly it seems.
Knock on wood, but I'd hope a tech wouldn't go that far to determine the fault of the phone. I assume they would if theres telltale signs of water damage to the display (streaking might be a common sign.) But, maybe, just maybe, they won't.

The service manual shows 4 of them, one under the battery that can be seen from the outside, one at the top and one at the bottom of the mainboard's other side, and.. one on the board that holds the bottom front panel switches, so very close to the LCD.
Personally I wouldn't have asked for a replacement phone, I'd have disassembled the phone and tried to clean it if made dirty by the liquid, bought a spare screen off ebay if it was definitely dead, and if ultimately it didn't work bought another phone off ebay for less than $400. But maybe I like risk

Keyboard membrane removal.
So, I've had trouble with my keyboard lately and wanted to just clean off the contacts on the membrane...but I can't seem to get the damned thing out of the plastic keyboard Middle Housing.
I have gotten everything apart so the housing is separated. Verified that I did it the way the service manual says...but i saw NOTHING about how to disassemble the keyboard from the housing.

Water Damaged Diamond... what next?

Hello all, while drunk at the beach this weekend I accidentally went into the water with my Touch Diamond in my pocket... stupid... I know, did I mention I was drunk? Anyways, the current issue at hand is what to do with my screwed up cell phone.
I took the backing, battery and SIM card out of the phone and let it dry out as much as I could since the weekend. When I turned it on this morning, the "smart mobility" text appears for a few seconds, but the phone shuts off shortly after that. Do batteries usually break from water damage, as well?
If anyone has any advice for me I would greatly appreciate it. Does anyone know of a legit place that can repair this? Is there anything I can do to try and remedy this problem? Or would you recommend I just sell/ditch this one and get a new phone? Thanks a lot.
Have you tried charging the battery? that might explain it only booting for a second, the other explanation is that it's fried the ROM chips and only the bootloader works.
It's not looking good, is it under warranty?
Disassemble your Diamond completely (manual floating around somewhere in this forum), clean all pieces using one of these isopropanol-brush-thingies, reassemble, turn it on - and pray. Any year - a new battery might be a good idea. No promises on anything of that though. The diamond is a very integrated piece of technology and you might have short-circuited something on one of the PCBs really. No guarantee that everything will work as usual even if the device comes up as well.
Warranty seems to be out of the question - I guess virtually any repair center will notice residue of loads of salt water on the first look inside...
That's true, I meant to say insurance, heh.
Strip it down Salt water is very and I mean very corrosive ! You have nothing to lose and everything to gain by doing this . Waranty repair will be expensive.
Clean with an alchol based cleaner as advised but you must ensure you get all the salt out. To see it boot means that the screen has survived ( Amazed by this ) .
Best of luck , oh and if it does not work are you insured for accidental damage on personal items on your household insurance. This could be the next route
I have the same problem with my Tytn 2. It got wet during the "Oranje" Party in Basel, when the firemen were "cooling" down the fans...
It boots..but as soon as it has booted, you here a lot of "bling..bling..bling.." and it shuts down.. the batterie doesn't charge..
You recommend to open and clean it with alcool? Actually I'm not sure if it was washed by the firemen or by my own alcool .ehhehe..
I have a Diamond now, but if I get it back to work, I would sell it on ebay.
Regards

There is a watersensor inside the diamond. They'll notice that the device has been in the water.

Luckily I was at lake Michigan in Chicago (fresh water), for whatever that's worth, so I'm not really worried about salt corroding anything away. I bought it off eBay unlocked, I did buy insurance but, naturally, I'm pretty sure that this water damage won't be covered.
Sounds like taking it apart and cleaning it might be my best bet. Do you guys think that any cell phone repair place would be able to help me out? Anyone know of a good cell phone repair shop (in the U.S.)? Thanks for the help thus far guys, I really appreciate it
Firstly remove the battery and SIM, please do not try to power up or charge again as you might have already damaged it beyond repair.
Isopropanol or IPA is what you need (100% Alcohol), you can get this from your local chemist for about £5 a bottle.
You need to strip your phone down completely and use an anti static PCB brush to clean the whole lot (Buy it from Maplin), submerge it in a plate of IPA (excluding the screen) while cleaning. As for the warranty sticker remove this by first heating with a hair drier, then uing a Stanley knife point to remove it.
Once it’s all been cleaned and dried in air, re-assemble and power up. If it fails to work take it back for a warranty replacement. As the warranty sticker is intact, and all the evidence of water damage will have been removed, they should replace it for you without a problem.

Pretty sure? I would check if I was you before doing anything else with it. If insurance doesnt cover water damage, what does it cover? Phone insurance is so expensive i thought they covered everything like theft and accidental damage, I thought the idea was a warranty wont cover you if you break the phone but insurance will.
I'm thinking it may be an idea to check before you do anything else so they dont say "Well we cover water damage, but now youve taken apart the phone we cant cover you"

or doese he mean "Swimming Diamond" ... Is that a new feature we overlocked? I think it's time for another entry in the tweaklist... *rofl*
My warranty does not cover accidental water damage, that is for sure.
I charged the battery up over the weekend and tried turning it back on, and, to my utter amazement, the phone completely powered on. I got to all of my menus and was able to use all of the programs that I opened, even the WiFi worked.
However, the functionality of the touch screen is quite screwed up. I don't know if its shorting out or what but there are basically "ghost taps" and other unintentional actions happening all the time. For example, if I were to just leave it at the home screen it would eventually scroll to another menu, open the start pull-down menu, automatically open the calendar and start doing random ****, etc.
Does anyone know how to fix the touch screen or have any ideas on how to replace one? I have a faint hope that this thing might not be beyond saving.. thanks a lot people

Maybe try to re-calibrate the touch screen?
Don't give up hope, sometimes these things can take days, even weeks to fully dry and become functional. My mom had a sony ericsson somethingorother that she loved, dropped in the tub, didn't work for like a month or more... She'd check it every week or so to see, and slowly the features started coming back... Little by little, more and more buttons would respond (without activating 2 or 3 at a time). Well, long story short (too late?) works 100% now. I don't think water damage is a reparable occurrence, but DON'T sell your Diamond for parts or anything like that, keep it around and check back periodically. Best of luck.
there is a little white sticker onto the battery.
If it goes RED it shows HTC that the Phone/Battery went into the water.
This allows HTC to avoid repair "sunk" phones

Should also be one on the phone... If not, there's your solution. New battery + deny any water damage = Free replacement.

[URGENTLY] How to replace digitizer on lcd

hi, i have my phone opened, and i dont know how to replace digitizer on my LCD screen which i take from phone
Please Urgently.. Thx. Mike
P.S. Must i open LCD scr.?
I'd advise replacing the whole screen as digitizer is glued to screen, there is guides to how to replace the screen which can be found via search one of them is very easy as just remove the four screws from behind the screen.
Good luck
If your only replacing the digitizer, which isn't easy I have done a few.
You will need to carefully remove old digitizer, I heat up the digitizer where it's glued and remove it, it will come off in pieces (glass).
then clean residue glue off lcd frame.
then glue the new digitzer.
last part is soldering the connector on the digitzer to the connector on the lcd it's not easy, it can be done with solder iron but I use a rework station makes it 100 times easier.
good luck
now it isnt urgently.. on night i closed phone.. but it is strange.. my slide effect is strange.. whn i put phone on table, so UP part (LCD,action buttons) is little moved right than DOWN part.. for ex. i think this slide after closing has opposite direction !BUT ONLY LITTLE (1mm)!
thanks for advice..
and i think this thread can could be good tread for everyone who dont know what to do with LCD. As me
I would also advise to replace the entire screen. They are easily sourced from a well known auction site and most will supply the opening tools and a screen protector.
A simple web search will find the service manual to open your pda. There are tuts for replacing the screen by removing the 4 screws behind the screen and pulling the housing apart to slide the screen out. Bewarned that if you are too forceful you will damage the mic and other parts that are still screwed to the board.
I bought two Xda stellars some time back. Both needed a lil TLC. One a scratched screen the other the housing was badly scuffed. Having repaired a few PDAs, I thought I would ask an independant store to see what they would charge (labour only as i would supply parts). He quoted £20 for each phone, have a look at the service manual see the steps to take it apart and reassemble ask yourself for the sake of £20 is it worth the aggro.
Good luck with your replacement, I hope this helps and any others who encounter similar issues.

Simple answer, No !
ok, on kaiser i can use only kaiser LCD? (no vogue,no tytn 1.....)
Correct, the Kaiser motherboard is ONLY compatible with the type of screen it originally came with.
I heard the t-mobile wing digitizer would work on the tilt.
I have not try it, maybe on next one needs new digitizer.
My son has just broke the screen on his tytn2, reading through there seems to be the screen itself and the digitiser behind, if I order both of these, are they a simple fit, someone referred to soldering, I do not want to go down that route................
Just found how to video on you tube, looks fiddly, but I will give it a go.

[Q] Dust in front camera...

Ok I've been everywhere and tried everything short of breaking out the torx. I'm not under warranty anymore, and of course it didn't start getting dusty until after it ran out.
if i take the back cover off and blow compressed air in the slot by the main camera it clears most of it out but it's all back within days. i'm only getting dust in the front camera area, none in the screen itself that I've found [I've taken it out in direct sun with no screen protector and scrutinized it].
I'm wondering if maybe the screws on the motherboard are loose or something creating a gap, I've dropped it a fair share of times. I can find teardowns for replacing the screen but nothing specific on the front camera, and being a nervous nelly i want all the info i can get my greedy hands on. I *think* i know where the parts are but cant find anything specifically saying "THIS IS THE CAMERA NEWB". I'm perfectly willing to take the case apart and the board out but i don't want to touch the glass, i'd probably get more dust in than out.
So to summarize my request =p
1. Anyone know of camera specific teardowns?
2. Anyone have this problem themselves and fix it?
3. If it does involve taking the glass off would it be worth it to pay someone to fix it, or is it more cost effective to just upgrade?
Hey, lucky you I just cleaned it myself. At the price of almost screwing up my incs forever. Look up YouTube on dismantling the incredible s, take it all apart, clean it from behind and fix it back. Had some loose connection when I was fixing it back so my screen couldnt light. Now its as good as new. Advice that if you try, be very very precise and careful. Good luck! :thumbup:
Screen is seperated from camera, don't worry about getting dust in there. Use the replacing screen video, sufficient information for you to tear it up. No video guides to fixing it back unfortunately, so just download the video, find a player with the reverse play function and do as according(nahh I'm just kidding)
You don't need to be a technician to do this. No brains required. I don't have any. Have fun!
Sent from my HTC Incredible S using xda app-developers app
I "had" dust over front camera too!!!
I didn't mind it; I'm talking in paste tense because my phone should be now in HTC's repair centre in Como with:
-dust under the screen ( top left area)
-but mostly because part of the digitizer is gone: a vertical row of about 1cm on the right...
So I think it's a common problem, pay attention on the screen...

[Q] Replacing a Xperia Z1 Cracked Digitizer

Hello everyone!
I bought a Xperia Z1 two weeks ago, and it was the best phone I have ever had.
However my idiot brother Managed to crack the Digitizer a few days back, the display is still working and the phone powers up but the touch panel is unresponsive.
(He was playing with one of those Heavy Snake Egg magnets, he threw the magnet into the air, and landed right on my phone. I'm surprised the Display is still working. )
Anyways, I was wondering if anyone here has replaced only the Touch Panel. I know on the Xperia Z1 its fused with the LCD, however with a machine like the Scotle PR-1000 its possible to separate the LCD from the touch panel.
Here is the link to a video showing the process: https://www.youtube.com/watch?v=h8bZi3FreMk
Now I have a few questions such as:
-With this method, wont the LCD display be scratched up as well?
-When I replace the touch screen with a new touch panel using this method, will it look normal? Or will it look like it has been opened and repaired?
-With a new digitizer, is the phone still waterproof capable? (I dont really care about the waterproof capabilities that much anyways.)
Thanks!
Can anyone help me?
You could just replace the entire display module, digitizer, LCD, and all. This would be the cleaner and easier way of replacing it with fewer potential problems. As far as waterproofing goes, I am not sure. Those are sort of uncharted waters (no pun intended) as far as repairs go. If I were you, I would assume not just to be on the safe side, until further knowledge presented itself. I hope this info helps!
FOr the past few days thats what I was thinking.
Especially since where I live most Cellphone "technicians" are just people with a very limited knowledge of electronics, and would most probably mess up the phone even further.
after placing a few calls to some shops I managed to find a replacement LCD+Digitizer+Frame, but I do not know how good the quality of the replacement unit would be.
Dear WEM97 and other users,
I have the same problem as Akash434. Could you please briefly elaborate on what the (potential) problem could be with just replacing the Digitizer. I can't really decide what to replace the LCD+Digitizer or only Digitizer. I understand replacing the whole LCD unit along is a far, far easier process. But cost wise it's also almost the double (atleast where i live).
Upon removing the Digitizer, should the old glue be removed (if any). What kind of glue should I use to stick the new Digitizer? Will u see that there was glue used? These are just a few questions I am struggling with.
Your help is greatly appreciated.
PS: I apologize for any grammar mistakes. English is not my native language.
you can't do this without a professional machine
https://www.youtube.com/watch?v=yMj-aWbttJk
This is my video and the description will send you to the links to fix it yourself
Otherwise get a shop to fix it... although most regular shops won't fix it... or get sony to fix it if you wanna continue your warranty
Place the phone on a heatable-3dprinter-bed and warme it up the temperature you want - digitizer was falling of the display last time i repaired my z1. I heated it up to disassemble. Now it is cracked again and i just don´t know how to glue the digitizer on... If i would change digitizer
