When you start taking these devices apart, you have to be very cautions. I've learned this the hard way . It's not something for the faint of heart. It sounds like something didn't get put together quite right. As for the screen being dark in the first lace it's most likely the LCD that's gone bad. Another thing I've picked up is that unless you just dropped it, and the digitizer cracked ( Glass ) . You should just replace both as an assembly. The digitizer, and the LCD together. It just makes things easier in the long run .
i dont understand why the first time it worked just fine but the second time it didnt
Well the thing is there's so many chances to mess something up. If you didn't connect the pins just right. If the glass is not sitting in the track. One of the ribbon pins bends. You really have to be Uber carefull.

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.
Hi. My HTC Inspire had a cracked screen so I bought a digitizer replacement, and the disassemble/install/reassemble seemed to go ok. But after doing so I turn on the phone, it makes the little vibrate as it starts and then the screen comes on but as a low glow and doesn't go past that. Don't know if the phone is booting all the way or not, just see the glowing screen.
Did I screw something up or is there something I can do to get past that?
I've done a soft boot, the battery was removed for an hour while I was replacing the screen, the SIM card is firmly set, etc.
Thanks for any help!
Well, the phone was sitting here "on" (still only with light glow) and I heard text messages coming over and the little green light is now flashing so the phone is up and running apparently, the screen just isn't showing. But it's has the light glow, is it possible the new screen isn't all the way set in place even though it has the "glow"?
Thanks!

Sounds like the screen is getting power but one of the wires is not put back completely. Made be you reversed the wires when you reattached them
Thanks a bunch for the reply. When attaching the glass to the LDC there's the little thin ribbon that inserts into the little white plastic clip, and then the wider ribbon part that slides up the side slot and snaps into place on the other side. Besides those two, would there be other wires I should look at? Those two look nice and secure.
Thanks again!

I have not taken mine apart yet but I walked a buddy threw it over the phone. Are you sure the cables are plugged into the right connectors? I think he also mention 2 plug in plugs that needed to be attached as well. What I would personally do. Is take it back apart and make sure everything is cool. Making sure the ribbons are not pinched or messed up and making sure all connectors are connected firmly.
Yes everything is plugged into the correct place, actually only fit in specific areas. I've just finished taken the phone apart for the 5th time and the ribbons are all flat, not kinks, seated fully, etc. I'm starting to wonder if the screen I got is faulty. I'll keep piddling with it.
Thanks.
I cracked my screen a few months back, and right after it happened I bought a new digitizer to replace the cracked one. The install didnt go very well, since the tape used to adhere the digitizer to the LCD got mangled during removal of the original digitizer. Dust ended up getting between the LCD and Digitizer etc. One other problem I ran into was that the LED's that are supposed to illuminate the home/menu/back/find buttons were now shinning up into the screen and washing it out.
Anyways I got fed up with the dust and bought a new fully assembled screen/digitizer off ebay. I installed it last night and everything is great except that the lights are still shinning up through the glass and washing out the lower inch of the screen. I dont see why this would happen as there is really only one way to put it all back together.
Any insight as to how to get the lights to stop doing this?
Thanks!
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?

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.
(located a few mm in front of the ribbon cable that connects to the lcd assembly.)

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.
Hi!
A few days ago I dropped my phone and until it hit the ground, I accidently kicked him with my leg and it got knocked by the wall and finally touched the floor. When I lifted it up from the ground I noticed what you see in the picture. It look's like an air bubble between the screen and the screen protector. But this bubble is underneath the first layer of the screen. Until today the "bubble" hasn't expanded, and I hope it wouldn't go further. My phone has still got the warranty paper available, idk if I'm going to send my device to their service and they will repair it...or I can go to a random service to check it out and maybe they will be able to repair it, or do worse...
What is this "bubble" afterall?
Screen is made of multiple layers, the digitizer (for touch) is the top layer iirc, the screen LCD is underneath, usually glued together, looks like the two have separated

Any chance to repair it without great costs?

Without replacing the screen, not sure, I know you have to use a heat gun to melt the glue between the screens to replace just the top glass layer, so it's possible if it has just come unstuck that could melt it back down, but might make it worse
