I ended up messing my n7100's digitizer, it fell and cracked. I replaced the digitizer but now the phone turns on but the screen stays dark. I can hear it, i had a hdmi adapter for the phone to connect to tv and if i do that, i can see the phone is fine but the screen is not working.
I had bought the phone LCD/digitizer assembly online and returned it as the first one didnt work then i got another from the same vendor as a replacement and it is the same. I dont think i got two bad digitizer assemblies. At this point i am thinking of sending it to samsung but can anyone point out some steps that i can do to maybe bring it back. already spent 200$ for the digitizer and i know what i am doing so i dont think i am broke anything.
any guidance will be great.

Hi, I just bought a replacement digitizer from ebay, I first have to say that this will be my first replacement, so maybe I missed a step. So after I replaced screen, I connected the 3 connectors like they should, I screwed the one screw on the top right, and screwed the 6 t-4 screw. I turned on the phone, and it seems like it wont register touch. It also seems that its more responsive to touch when plugged to the wall. I was able to get to the calibrate touch screen, I was finished with that and still no response. So now my question is...
A) Did i miss a step?
B) Is this something common and can be fixed with settings?
C) Does this sound like a bad digitizer?
I emailed the company that sold me this digitizer, and they will exchange my digitizer. But before I ship it back I would like to know if it was me who is doing something wrong, or if its the digitizer.
ps. Not sure if I can post the link to the ebay item...
A customer brought her G2 on simple mobile to me with this problem: The letter "A" wont work on portrait mode nor will the home key. I figured it was the digitizer so I replaced that with an OEM Replacement part and as soon as we booted back up the problem was still there. Could it be her OS is corrupt or possibly a warp in the case thats keeping the plate from contacting the faceplate. I'm rather stumped as I ran a logcat and I saw nothing out of the ordinary during normal input. Any help is appreciated.
Touch plate? I am confused to what you mean by this. I am not too familiar with the electronic construction of a digitizer so any info would be helpful.
The digitizer isn't coming in contact with the face plate I believe. (Sorry I used like three different words to describe the same thing in my previous post) Any tips on how to fix that would be great. I saw a video on youtube that stated a part where a heat gun would be used but I never came across a front panel (The part with "T-mobile" on it so I installed the digitizer and went along). I think I may have messed up.
i have the same problem, i dropped the phone, and the touch screen was broken, i replaced it but now the left side and home button arent worksing
ps the broken screen worked still also on the left side , did you find a solution ?
I have the same problem.
I believe it's the ribbon cable, not the Digitizer. The ribbon cables on this phone hangs between both screens and is fairly exposed at times.
I still have a couple weeks in my warranty to return it to HTC, but I can't get it to S-on. Unless I get S-on before warranty is up, I'm going to have to replace it myself.
Ribbon cables for this phone cost ~$30 on ebay. tell me if you fix it.
Any luck with this, anyone?
I have broken screen on my htc desire hd, i have replaced the LCD+digitizer before. i know my way around this phone.
Is it easy to replace just glass screen ?
I cant see how i can seprate them. they are glued in this black glue thingy.
Better buy whole LCD + digitizer?

I need to do the same. Also since dropping the phone my Bluetooth turns on and off but doesn't always connect. (highlights or ticks option , but I'm not getting anything on the top bar). I disconnect and re-connect a few times to get it working
While I have the phone apart is there anything I can do to fix it?

I just replaced the glass only on mine. Unfortunately, the touch screen isn't responding. Anyone know where I might have gone wrong??? Everything else seems to work fine!
Probably a Ribbon Cable.

Try taking it back apart and re-place the ribbon cables back in there seat, they may not be making proper contact. If you replaced the glass without taking it apart you probably un-seated one of the cables. When working on iPhones there is a cable that is only held in place once you close it and put the phone back together.... It's a PITA.
Buy new part and dont replace . Your self its difficult. And its not easy
You can buy a "used" DHD device to replace yours. It'll be cheaper and easier... With a backup on sdcard, your device will be the same !
Hey there,
So i need it to replace the screen because of a failure in the digitizer, I play brave and just got the digitizer and try to fix it by myself, and as everybody else here have mentioned the task of separating the digitizer from the LCD is impossible, so i endup destroying my lcd.
In the middle of the video(5:36): watch?v=OIeO0DueMcg (Sorry i can post links so that is the rest of the url in youtube) they show how to test if the LCD is well connected, so I did that test, and plug my old lcd(before trying to separate the digitizer) and plug the new digitizer and it was working well, and thats when i took the courage of separate them, and obviously I failed, half way in that process, i want it to check if I was doing well so far so i plug the LCD and I saw it dying, it kind of went on, change colors, and show the crack that i have done so far in the separation process. DAMN!
Anyways, I knew that was the risk that i was taking, so I ordered now the part with the lcd and digitizer together from Repairs Universe and I got it today, I installed, and didnt work, try the same test than above and it didnt work. I completely ensamble the phone, and i can hear all the rebooting process, but the LCD still doesnt work. I plug it in the computer and use adb, it recognizes the device and even the touch screen events by executing
Code:
./adb-mac shell getevent
So definitely the phone is up and running, but no LCD, is there any chance that the part that i received is incompatible? I reside in South Africa and got the phone here I assume my version was the international one. Is there anyway I can test that LCD? Any suggestions??
Thanks,
Gustavo.
PS: i post this exact message in the long forum about it, but i though that this might be more visible. sorry if you see it as span.
hi, have searched and searched on the forum but no real answer to my problem.
i dropped my htc one x and the glass cracked, so i sent it away to a supposed reputable firm (i didnt realise htc repaired phones aswell otherwise i would have sent it there)
anyway the lcd display and brightness worked perfectly, the company have replaced the screen and now the backlight no longer works and flickers when touched or cpu is being used.
they have said it is the display IC, and coil etc,
they say that this was caused by the phone being dropped, and not by them and they have charged me (they take payment before sending phone back), they initially took the phone back, and 3 weeks later they have decided to wash there hands of it, have put the phone back together shodily tell me i have to put up with the phone as it is, and refuse me a refund.
they acknowledge that the ic was fine before they took it apart, but blame it on the nature of the phone design as to why it now doesn't work.
i would post link to another forum explainingg the possible issue (has no explanation of cause though) and pics of the phone has been returned to me, but i can't because im a noob
Basicly the question is,
Who is at fault?
And how could the ic get shorted out,
The backlight flickering is likely to be poor installation of the new screen.
Again this is an old example I'm referring to here. I used to replace the screens on the Nokia n95 quite regularly.
You get the screen assembly and the ribbon cable which attached to the motherboard.
If the ribbon cable was not seated 100% perfectly I would get the exact same symptoms you are describing.
No backlight. Pressing down on the screen would either get it to flicker or come on for a while.
It shows a poor connection. I took the screen back out and repositioned the cable back in. Reassembled and then it was fine after

Hi mate did you managed to get this sorted I am having the exact trouble same issue with a company call Elite Phones and Computers.
They are saying that the IC shorted out and the only repair would have to be a replacement board.
