I know this is a hardware question, but I'm hoping someone might have an answer.
My son cracked the screen on his Galaxy S Blaze. I ordered a replacement screen assembly and found a video which I thought showed how to replace the screen, but it was for a different model. I have the cover off, the flex cables disconnected and the motherboard out, but I can't figure out how to remove the old screen from the front housing. Based on the other video, it should be a combination of heating the edge of the housing with a hair dryer until the adhesive softens, then prying it off. I've tried to do this with no luck, but it could be that I'm not prying hard enough - kinda scared to break it.
Does anyone know how to remove the screen - or better yet, know of a disassembly guide for the Galaxy S Blaze?
Thanks!
Heat, Heat and more heat...
Be careful with the heat as it can destroy amoled
a little off topic but...
One of the pins on my usb port got damaged. I was curious and took off the cover to have a look at what would be needed to replace it.... too much soldering that is above my skill level. Anyways, in the process of removing the cover, I lost functionality of my hardware buttons. I'm assuming I damaged the cables that attach them to the mobo. Didn't notice this until I put the cover back on and booted up. Does that seem right? Was I just being too harsh while taking it apart and ripped a ribbon or something of the like?

Has anyone seen a good take apart/repair guide for the Inspire4G. Just got digitizer replacement and cannot for the life of me figure out how to attach the ribbon cable without totally disassembling the phone. Hoping to avoid this.
If this is the wrong forum, please direct me to a better one rather than flaming me.
Thanks
Fairly certain that ifixit.com has a good teardown.

Thanks for the tip, but I find nothing for the DesireHD/Inspire4G there other than a total disassemble for the HD that I've already seen, but really did not help me. I just need to change to touch screen. I appreciate the try though.
Got it apart. And kinda back together. Apparently it is not a good idea to reuse the double sided tape that holds the LCD to the motherboard and the digitizer to the LCD. At least the phone works. Now, must order some proper adhesive tape and redo the whole thing.... Took me about 6 hours for whole breakdown and rebuild. Doesn't really seem to fit back together all that well though. Maybe I'll videotape my next breakdown.
Couple of questions as my phone is in need of a new digitizer too.
Did you have any other adhesive tapes in the process?
What did you use to cut the tape that held the LCD together after you baked it?
Does the phone mostly feel the same now that you have it back together, or does it feel flimsy now?
I'm disappointed that it's this difficult to replace the digitizer.

Just so you know, I was a TOTAL noob in phone deconstruction. That being said, the old adhesive seemed quite sticky after i took it apart so I just reused it. Mistake number one. Once it was back together, i notice it slowly opening up like an accordion. The tape wasn't holding and the LCD, digitizer assembly started to rise up. I have since ordered some adhesive tape from the place I got the digitizer from. Definitely get the tape.
I did not bake it as in the video (i assume you watched the same one I did). I used an old spark plug gauge tool thingie to just cut through the tape. It was still really sticky so after i struggled to insert the digitizer ribbon cable, I just reused it. Don't do this. Get new tape.
I did have some plain old scotch double sided tape. I used it in one spot. Lesson: Don't use this stuff. Get new tape.
Did I mention that I think you should get new tape? All in all, it was quite laborious. I went really slowly so as not to brick it. When it was done the phone worked, but like I said the LCD raised up after a couple of minutes. The adhesive was not working anymore. At least I have gained confidence for the next take-apart. I can't believe i GOTTA go alll the way back to total break down. Aaaarrrgh.
So something like this should do the trick?

Thanks for the heads up... Where exactly do you recommend putting the tape? Does it just go on the black edges of the digitizer, or does it actually go on the surface of the LCD? Sorry if that's a noob question, but I haven't gotten the glass off and I want to make sure I have enough adhesive tape from the Ebay Vendor. Did you have any issues with reusing the mylar?
Sorry for the 1000 questions, I really don't want to shell out off contract prices for another phone...
Mylars were all reusable if removed carefully. I photographed every step so I would know what to put back where. Still waiting for my tape from Repairs Universe. The biggest two culprits are:
1] Tape holding back of LCD to the silver chassis frame and
2] Tape holding SIM FPC to the main board.
You might also tape the PCB cover to the upper board, mine was loose after rebuild.
That I believe that is it for the major tape requirements. Of course the digitizer needs to be taped to the LCD. I'm curious, though, the tape framing the LCD holding the digitizer seemed to have some thickness to it. Almost like foam rubber, quite thin, but thicker than regular cellophane tape.
Good luck. Let me know if you have any tips after your attempt.
Got the tape. Retried to rebuild with new OEM tape. Same result. The phone when completed expands like an accordion. The digitizer/LCD assembly does not stay stick to whatever is under it. I know when to admit defeat. Looks like I'm shelling out 500 for another phone. At least I have spare parts!
yeah i was going to do my screen myself till i seen the tear down & then called afew places around here that does screen replacements and said NO we won't touch the Inspire, i spent the money and let HTC fix it. was worth it they replaced the whole shell not just the screen ... IE lcd / digitizer / Outer case that was scratched and dented... basically a new phone with the guts out of my phone
I attempted to do this and let me just say that I too now have spare parts. I purchased a phone off of ebay. I didn't realize the no contract price went up to around 500.00 I should have gone directly to HTC. Live and learn...
I will be in possession of an HTC Inspire for testing purposes that also has a cracked screen. Not sure how bad it is but I was planning on just replacing the display for learning purposes. However it seems that it may not be worth the time spent.
If I do decide to give it a go I'll post my results here. First thing is to acquire new tape. Did you all purchase it locally or did you buy the adhesive online?
YouTube has lots of videos. Best to watch a few a see the best way. If you are scared to break it best you send it in for repair instead. Get a digitizer and screen combo.
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.
My Tab 2 7 had a swirling crack on the digitizer (touchscreen). Looked for a tutorial on how to replace it in vain. Saw the teardown at Tech Republic, but that's it. No mention anywhere that I could find about how to do it. Decided to bite the bullet and ventured to fit a new one. Successful. Wrote down a quick guide thinking it might help someone since I saw a bunch of tabs with smashed digitizers on Ebay. Some claim it's gorilla glass, which makes me kind of wonder why they shatter so readily. I know, gorilla glass only scratch-resistant, but still...
Samsung sticks the digitizer to the bezel-frame with a tough double-sided tape, similar to the kind Asus uses on its tabs. A tutorial for the Tab 2 10 shows the use of a putty knife to scrape the digitizer off its frame, which wouldn't work with the 7, as its bezel-frame almost totally covers the edge of the glass back side. On the other hand, inserting anything metal in between from the front would scuff it badly.
The LCD display was taped to the magnesium frame, but is separate from the touchscreen, which need not be removed when replacing the digitizer.
What you need to do is to follow the steps in the teardown referred to above. As Tech Republic correctly pointed out, the internal layout is quite neat, unlike some of the tabs I've had the chance to disassemble. There are many thin cables, however, and you need to proceed with patience.
You must remove all components, so that only the frame with the digitizer and LCD is left. Eventually, you'd have to employ some source of heat, be it a heat gun, a hair dryer or a heat lamp to soften or to some extent melt the adhesive of the digitizer. Leaving any electronic component in place and the heat might destroy it. You can use brute force to separate the digitizer from the frame, but you'd more likely than not damage the LCD in the process.
What I did was use a heat gun at ~500 F, held at about 1 to 2 inches from the edge of the digitizer, and went back and forth over it, one side at a time, for no more than 30 to 35 seconds. I used a blunt object to push the glass out at spots plainly visible as illustrated in the attached thumbs below, then slid a plastic tool with a flared end to pry it from the bezel along its edge. Be careful how you handle the frame, since it would get burning hot at this point. As I moved from one side to another, I wedged a guitar pick between the glass and the frame to prevent them from sticking back together. You might pulverize parts of the glass as you go along, but in general it flexes quite a bit and wouldn't shatter.
Once you get it out, you need to remove the residual tape on the frame. The digitizer I bought was lined with new tape so I didn't have use any extra adhesive. It doesn't bind as strongly as the original tape, but enough to hold everything in place.
Putting it back is just the reverse. I took the extra step of reassembling the whole thing first with just the digitizer hanging loose, plugged it in, turned the tab on to make sure it functioned correctly before bonding it to the frame.
Basically, the process is nothing new. However, just the fact that someone has done it might give confidence to other DIYers in the future. Feel free to ask if any questions.

Thanks im going to give it a go. Any walkthrough tips by anyone else appreciated
Replacing the digitizer on this device is among the easiest ive seen. With no heat or taking anything off except the back I fixed one with only an isesamo
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)
http://goo.gl/TnXkFC
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.
I cracked my phone screen yesterday after getting it repaired. ($60) bucks gone. I figured I'd fix it myself. I actually did it. I noticed it wasn't getting any signal at ALL, I always get 4 bars inside my room and I remembered that I had moved the RF cable with the screwdriver that was magnetized. I don't know if that might have been the problem. Well after I put it all back together I fudged the screen and I opened it back up and I discovered this after I took out the battery. Screenshots follow
http://i.imgur.com/OMAE9Yw.jpg
http://i.imgur.com/V5sGFpI.jpg
What isnt noticeable is that the metal clip furthest to the bottom that helps hold the RF cable is gone, I couldn't get it back into it. Does that matter? If so I need to get a complete assembly then.
Also note that the LCD screen is not cracked. But it looks like it is bleeding.
What I want to know is 4 things.
1. Is it fixable?
If not, I'll sell on Ebay for parts.
If it is. then do I
2. I want to know what could cause the LCD damage the way it is, is it from pressing to hard underneath it?
3. Do I need a new RF cable?
4. Is there a name for the flex piece that is in the pictures? I know it is tied to the power, volume and camera buttons. If their is a part, I'll take it to a professional this time.
I found the name of the piece, Its called a motherboard Flex cable.
But Im really wanting to know If I need a new RF cable because of touching the end piece with a magnetized screwdriver fizzed it out.
Thank you ahead of time.
I guess you'll need to replace your whole lcd screen along with the digitizer. You could easily get it on EBay.
About your antenna cable. I think it's damaged and that's the reason your not receiving any reception.
Few months back i replaced my lcd screen cause of some touch issue i think i accidentally damaged the antenna cable and now i dont receive reception in my room or college classroom. I have to move out to get reception.
