Hello,
I recently had to replace my LCD/Digitizer and am having power issues. Specifically, that's discussed in another thread regarding a non-functioning power button. But besides that, I'm also noticing my new LCD/Digitizer sits loose. About halfway down the phone, I can see light omitting when holding it from an angle, (viewing from the side profiles).
My new LDC/Digitizer is very responsive and everything, but it didn't come with anything. Is there something I need to do in order to keep this flush? I've seen something about double-sided tape on other posts (concerning all phones in general), but where exactly would that double-sided tape go?
any help is greatly appreciated!
Thanks!

Hi,
I have just replaced LCD and digitizer of my HTC raph (first time) and there seems to be some kind of problem. It turns on, but the screen shows nothing just lights up a little bit and there are some stripes visible as if the lcd would be broken, but it's brand new. The stripes changes a bit as i press some buttons or touch the screen so the phone and touchscreen are working - the problem is with LCD.
I don't know if i put all the conducting tape to the places it originaly was. Could that be a problem? I double checked all the connections but still, might be a contacts problem?
Any thoughts on what might cause this?
Also the phone got kind of hot after having it charged for some time, is that normal?
Of course, this may be caused by a bad connection (but rather hard to go wrong slot), but at a distance hard to say something more concrete.
Best to check with the new flex.
Thank you for the answer, i will try changing the main flex.
The flex cables can touch eachother right? Since they're originally covered with conductive tape.
BTW, i also intend to change the lcd + digitizer... my question is:
how to apply the digitzier? lcd and digitizer came separated - do i have to solder/glue or whatever the flex (of lcd & digi.)?
The original was something like sticked together... reminds me on sellotape aka Scotch Tape.
Can you give me a some help?
thanks
The ribbons must be solded together, there's 4 contacts on them and they should not touch eachother.
Evening all.
So my beloved DHD needs the screen and digitizer replacing. Ive done the necessary reading/ searching and ive also located what appears to be a decent replacement.
Here is the thing.......
Has anyone successfully managed to do the replacement and keep the " Home, menu, back, search " buttons lighting up post screen replacement ? If so i would really appreciate some pointers on how you did this.
Thanks in advance
i replaced a digitizer / display on my dhd once and did the same on some Hd2 before.
On DHD its really difficult to replace the screen / digitizer. You most likely damage the plastic frame around the screen and indeed the arrangement of the Leds are no easy too, but not too hard to maintain. I wouldnt change the screen of anyone others DHD, just my own.
Yes, ive read that the replacement process is somewhat fiddly / tricky and no i would'nt do it for anyone else either. Im going for a pre assembeled screen / digitizer.
digitalizer is glued on lcd and lcd is glued on the middle metal plate, removing lcd from the plate requires heating it and it sure isn't fun, even after heating it it is still hard to remove without damaging the plastic frame, if i were you i would take it to a service shop with already bought part and paied them to change it, trust me it is not worth the nerves and the time
I'm a very handy guy and I accidentally tore a ribbon cable separating the pieces glued together. It's very hard, worth paying someone.

yes, but it was a pain, hold the pieces in place with double stick tape and be careful not to bend them!
Yup I successfully managed to replace a digitizer but I'm also a trained phone technician.
The most important thing is to be very careful. You should never have to use force in order to disassemble a phone.
How to get the cracked digitizer off? Simple, use your oven.
* Place the display-module (Chassis, digitizer,LCD) on a tray, make sure the plastic parts don't touch the bottom, so that it doesn't melt.
* Heat the oven to about 80-100 degrees celsius.
* The display should come off pretty easily.
* If you've done it properly, you can use the same adhesive that was one the chassis/frame if not you'll have to purchase some slow drying adhesive and carefully place it around the edges.
* Carefully move the light-guides on the bottom of the screen to the new digitizer. There's a small amount of adhesive on them so don't get any sweat on them. If they don't stick just use a very very, I'm talking pixel size amount of adhesive on it to get it to stick.
That's about it. Thread the flex-cable around the display and use a tweezer to connect it.
To make a long story short, my wife dropped her Samsung Galaxy S3 i535 phone a couple weeks ago and shattered the front glass. I ordered the replacement glass on eBay and proceeded to get it installed this past week.
One of the things I noticed was that none of the repair videos adequately documented how to route and attach the button for the home keys at the bottom of the screen. I was finally able to get the old home button ribbon cable detached from the phone and pulled free from its location. I noticed that there was still quite a bit of adhesive left on the resting location for the home key pc board (located a few mm in front of the ribbon cable that connects to the lcd assembly.)
I made the mistake of thinking that the adhesive consisted of some form of double sided tape, so using a small blade and a pair of forceps I began removing the adhesive. Turns out, the adhesive was attached to a felt-like material that was covering the back of the LCD. Once removed, I noticed that the section of the screen from which the felt had been removed was slightly discolored.
I proceeded to reassemble the phone with the new glass, and it is working correctly, with one exception:
The entire screen (not just the area where the felt was removed) appears to have a greenish tint to it. This is most notable when booting the phone. The SAMSUNG logo appears as almost a neon green (My wife assures me this should be white) and the booting animation is mostly green (She assures me it was multicolored)
A couple of questions here:
Did the piece of material I removed from the back of the LCD cause this problem, or should I be looking at something else for a solution?
Is there any chance this felt-like material contained the backlighting for the LCD Screen?
If not, could just a small section of missing felt allow enough light to escape to discolor the entire screen?
Also, since I obviously can't replace the felt, would coating the expose area with some form of paint or something work to restore the proper coloring to the phone?
I am currently looking at other replacement lcd assemblies which, from what I can tell, simply involve moving the motherboard from the old phone into the new assembly, connecting it, then putting the back cover onto the phone. If I can afford spending the $100-150 that these cost, I would like to avoid it. If this is my only suitable solution at this time, I would like a definitive answer so that I can make the purchase and get her phone back to working order.
Thank You all for taking the time to read my post, I can post pictures later to elaborate on what I am describing, but my wife and I are both at work at the moment and I don't currently have her phone to take a photo of.
Pictures would be nice. However your back light shouldn't discolor your screen. My guess is you loosed a cable or something else causing the screen to discolor.

I will get pictures posted this afternoon. After taking a little more time to look at it earlier today, it appears that Green and Blue colors are working, I just haven't got any red.
Do you know where to find a diagram of what ribbon connectors control what aspect of the phone?
Pictures
A little late, but here are the pictures of my wife's Galaxy S III (i535)

that will give you an idea of the connector for the screen. you say all you did was replace the glass? not the whole screen? I cant imagine how this would happen unless you damaged the ribbon cable when removing the glass.
unless you want to remove the glass again you'll have to take it apart from the rear, which isn't too hard really. take the back cover off, then remove all the little screws you see. that piece of plastic will come off and this is what you'll get: http://imgur.com/WwoOgMP
the red box is the connector, make sure it's seated. i'm not sure you can get all the way to the digitizer panel from the rear, but this is simple enough it's worth trying before removing the glass again.
also there are plenty of youtube videos on how to teardown the sgs3.
on a side note, task killers are bad for your phone.... use Greenify instead, or nothing at all.

If this ribbon cable that connects to the LCD was damaged, it might be your problem.
In that case, you will need another LCD.
It's best to buy the LCD and Glass as one piece.
About $120 or more.
So I ended up cracking my screen and installed a replacement last night. Everything seemed fine but I noticed, after putting it back together, that any slight bit of pressure or shock to the top causes my N5 to shut off.
I took it apart again to make sure all of the ribbons were properly connected and to take a second look and everything appears fine. I didn't have this problem prior to the replacement and I was very gentle during the tear down and reassembly so I don't the the CPU or anything on it is damaged. Other than the top being hyper sensitive the phone works perfectly.
Any ideas on what the problem is or could be?
SOLVED(sorry, I don't know how to change the title)
I just wanted to fill in anyone curious or running into this problem in the future on how I resolved the issue.
So after some time I narrowed the problem down to the second back cover (the one with the camera lens and beneath the Nexus branded cover) making contact with the motherboard. More specifically, compressing the power management IC with its aluminum cover. You want to make sure that chip is laid flush which was a PITA, for me at least, because the headphone jack and earpiece speaker wants to push it up and out. What I did was put the jack in, lay the board on top, then gradually adjusted the jack with tweezers while gently pushing the motherboard down until the board was flush, then placing the earpiece speaker in.
I then placed the second back cover on and tightened the screws until I could feel them just slightly putting pressure on the cover. I can't stress how light this pressure is as it is the key in resolving this issue. To compare it to changing your oil filter on your car; when you can feel the filter make solid contact with the block and you then turn it about another half turn to seal it; it's like that but without that half turn.
Anyway, I hope this helps anyone else unfortunate enough to both break their screen and then have their phone randomly shut down when any pressure is applied after fixing it.

I bought mine off of eBay and it cost me $150. I could be wrong but it looked like the screen can't be separated from the frame. You might want to keep that in mind when purchasing because there are sellers that sell the screen without a frame. Tearing down the N5 was pretty simple. The hardest part for me was getting the back cover off as there are 4 (two on each side) large clips. If you end up bending the clips any, you can push them back to shape to keep the back from creaking like every Samsung I've ever owned. There's a nice guide on iFixit if you want to look at the process prior to ordering a new part.
I've read from others that you can send your phone into LG and they'll repair the screen for you. When you send it in they'll email a quote to you within a day. The price I keep seeing is $146 and I have no idea what the turn around on that is.
When replacing my S4's lcd I also decided to replace the frame/chassis. I used double sidded 3mm tape around the edges so the glass would stick to the frame/chassis, though some of the tape has lost it's stickyness. The glass has somewhat lifted up (I can get my nail underneath and lift the glass, i'm unsure if the lcd lifts up too), the areas of which have lost their stick is around the top corners (mainly around where the LED is but i've noticed it along the whole top of the phone). I've tried lifting the glass slightly and putting some more tape underneath it which has not work, also, i've tried heating it up with a heat gun which also did not. I am contemplating using hot glue but a the time being I am still undecided if it will be effective.
Has anyone else face a problem similar to mine? If so how do you correct it? Does anyone have a solution or any tips? (please note that this device is not under warranty of any sort)
Hi, thank you for using XDA assist. The best place to ask is in your device specific forum. I'm not sure what version of the S4 you have so try one of these, http://forum.xda-developers.com/galaxy-s4-att or, http://forum.xda-developers.com/galaxy-s4
