Hey guys,

So i grab a new screen digitizer from there:

Well, i replaced the screen successfully.
I know the nexus 7 boots because i hear sound of new mail, and when i touch the place where navbar is I do hear sound, but the screen is black Oo.
I checked all the ribbon 3times and they look good, any idea what can cause that? maybe the ldc flex ribbon is broken?
Thanks for your help

I have the same problem, only I obtained an LCD + Digitizer assembly. Did you eventually find a solution?
Thanks,

Broken LCD

Hello all,
My Touch HD slipped from my hands and ended-up flat on the screen... the screen does not have a scratch, the digitizer still works perfect, but the LCD underneath is broken, so I get a black screen. I can still access the Touch HD via my PC thanks to MyMobilier, though (so why do I complain, huh?!!)!
I ordered a replacement LCD in Hong-Kong (thanks ebay!), got the HTC Service Guide, managed to remove the antenna cover (tough!) and dismantle the whole thing. But NOW I AM STUCK with the 'bezel', i.e. the cover, screen, digitizer, LCD, and metal plate with bolts all apparently glued together.
Anyone faced the same problem? Anyone knows how to separate the LCD from the screen and digitizer?
Cheers,

Anyone can help with this???

HTC HD2 dropped, Black Screen, but touch and whole phone works well

Hi
I've dropped my HD2. Everything is working, including touch screen, I can unlock the phone, I can answer the call, but screen is black, not broken.
What should I do? Does the lcd screen replacement will be sufficient? In that case, could the screen be ok, but some other display "processor" could be dead? I'm asking because I'll try to this on my own.
Could simply be the lcd cable has slipped slightly but probably more likely an LCD replacement needed.
You need remove rear housing & have a look & make a decision from your findings/testing.
hello
I've got a little update - lcd screen is working well - I mean it displays the image, the only malfunction is backlit. Right now when i use flashlign I can actually see whats on screen. Do you have experience or think that backlit connection can be repaired? Do You have any schematics for hd2' lcd ?
I suspect new LCD required by sounds of it. LCD can not be stripped for repair so after basic inspection of external connection replacement is only solution & not expensive due to falling cost of HD2 parts.

Touch don't work after Screen replacing

[Q] how to find out if digitizer works properly in broken nexus 7 (2012)

Hi, a few days ago i broke my nexus 7 screen . There is a huge crack on the screen and the touch works only in a small portion of the screen. The display is coming right though. Also, the broken screen seems to be touching the touch somewhere as the device sometimes responds without even touching the screen. How can i check whether i need to replace LCD glass only or i have to replace the glass along with the digitizer?

LCD screen is glued to front glass/digitizer. Its possible to change only digitizer, but don't think you will do that at home ... Easiest way for you - change all LCD-digitizer assembly ...
