[Q] Screen artifacts - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hope t his is the right place to post this. Just replaced the glass on my TM217A and now have "blobs" on the display. What did I do wrong? Any way to fix it? They are on the LCD panel itself, noticed them when I turned the tablet on after remove the old glass and before installing the new.

it looks like you bent/deformed the part,
you mean the digitizer right ?
as to fixing it, you may have to get another replacement.
those bubbles are probably sealed in now. you could try remove the part gently
and clearing away the adhesive to let the air [which is what it looks like] escape,
and try again.

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.

[Q] Touch Pro 2 Screen calibration failed ?

Hi everybody,
I have problem with my HTC Touch Pro 2.
It was fully working until I damaged my LCD screen and digitizer.
So I ordered a new one LCD and digitizer from ebay. I changed old lcd and digitizer, booted up my HTC and everything looked allright. But problem came soon. Touch screen can't recognize my touch exactly. For example, if I click on something, digitizer solve it allways about 2-3mm higher. So I can't click on start, battery and every other click is moved about 2-3mm higher.
I made a calibration, but without any effect. I made a hard reset and than a calibration, problem still same.
And if try to make a new calibration (after first calibration after HR), I click on first cross (in the middle of screen), then up-left corner, down-left corner, down-right corner, up-right corner and nothing happens, I have to click on first cross again... and whole procedure again... So I have to make a HR and try to make a new calibration... still same problem.
Could anybody help me please? I'm going crazy, because I like my HTC and I can't use it anymore.
Is there any other way to make a calibration or how can I repair it?
ROM:
Energy.RHODIUM.29022.Sense2.5.Cookie.2.0.Jul.04.7z
(I have this ROM before I damaged LCD screen, any it worked fine)
It almost sounds like the screen/digitizer aren't lined up correctly... Just my .02.

Ok, then It seems to be a HW problem between screen and digitizer?
So what can I do now? Try to repair it again?
How can I check, if digitizer is OK? or could be digitizer bad at all?

I'm just guessing from your description. I've never actually replaced the screen... If the two have to line up perfectly, I would ensure they are lined up correctly. Perhaps try slightly moving the digitizer down...

Ok, thanks. But I can't move with a digitizer, because it is in fixed position. Maybe I can move with a screen under a digitizer, but then I will not be able to see whole screen (digitizer has a black edge/margin/border).
Any other suggestion?

Nope, all I got. Calibration always works perfectly for me - if calibration doesn't work, there certainly must be some hardware problem. You replaced the screen, unfortunately you must establish where the hardware issue lies.
I don't have any help for you, sorry, just jumping on the wagon. My touch screen worked fine for a year but is now way off (1.5-2 inches sometimes) without having damaged the screen to my knowledge. I've switched roms (from MR.X to Mighty) and hard reset. If I try to calibrate it just keeps running through the process. Should I try to replace the digitizer? I plan on getting an iPhone if possible on Sprint in the coming month but would like to sell this for at least a little bit.
To both of you guys - have you ensured there's nothing between the screen or digitizer? Nothing that is wedged on the edge of the screen...?
I know some had reported complete screen failures just from some gunk that got wedged on the side of the screen.

Thought about that, but dismissed the tiny little amounts of gunk on the edge..currently searching for a toothpick or something small to clean out the edge. Thanks for the idea! Will report back.
Thanks so much arrrghhh! Found a small pin and got out most of the dust/gunk that was between one side of my phone. Apparently that bezel side is just a little bit looser. You saved me lots of time and money! Thanks. Always helpful on here and PPCGeeks.
Edit #2: Must still be more junk because the 100% functionality just went away. Time to clean it again

Front Disassembly?

I'm wondering, if anyone knows how to remove the Front assembly without cracking it. I got a cracked galaxy s 2, and i needed to do was fix it. So i replace the front assembly, but i didnt notice these white pads under the touch keys, so there are no back lighting behind the touch keys atm
Anyone know how to remove it safely? I got rid of the old cracked screen simply by prying it off, and i dont think it was something i'd like to do again since it can quite well just damage my new screen.

There is a sticky on how to replace the screen. Its the 1st thread in this forum.
Unless you are speaking about removing the actual glass from the housing. This thread would help you.
Btw I mispressed "thanks" soo free rep for you.
This is the screen from the front assembly itself. My lcd came with the LCD only, i had to attach it to the housing, as in i had to pry off the old screen and put on the new screen, so i had to take off everything including the touch keys.

Broken LCD?

Hello Guys.
I dropped my phone today and when I lifted it up my screen was blue/black. I pulled the battery out and turned it on. Most of the screen is black and can't see anything. There are strips of blue pixels here and there.
What exactly is broken and what do i need to replace. I obviously need to replace the Glass frame/screen, LCD ... do I need to replace the digitizer as well?
If anyone knows about this please help me out.

As long as I know any T999 i535 I747 will be compatible except I9300. I dont know why but some T999 users havd problems.
Is a good deal indeed. But If you can find some with frame includes will ve a very sweet deal.

I know sound expensive but you only will have to change the mainboard and components very easy without any need of stick or glue to install it on the frame.

Yes, the only concern I have is the glue used to join the frame with the screen, if isn't professional installed this will be falling soon or getting dust an sand under the screen. Thats why I recommend the entire frame and screen set...

[Q] Display problem - local greenish pixels

Hi,
please have a look at the attached image, cause its hard to explain.
It was kind of strange... it started with some cloudy pixels in the middle of the screen, they went down to where they are now and got more intense.
Its now there since about 4 weeks without change.
Anyone experienced it? I guess I need to replace the screen, or is there any other chance? In case I have to replace it, what would I need to get? The touch screen digitzer or the full lcd display?
Thanks
Susi

Although i'm not an expert on this, But i should suggest you to replace Digitizer only because it seems like Display is okay just chemical imbalance between digitizer and display panel.
If you've proper tool to disable the device and with some flat hard plastic or something try to take this to the edge where it easily go out. To me Display seems okie. Because such things happen when we put phone in tight jeans and due to over compression such happens but it has nothing to with display panel, its just chemical in between display and digitizer.
I had an iPod 4th Gen,. Same kinda Dark black spot i've noticed after single drop on top right corner and later it disappear automatically. So just saying try that first rather buying whole new panel or digitizer. Flat blunt plastic to take that bubble to the side
