HD2 Wont Power On Suggestions?

When i disassemble my hd2 and then reassemble it does the whole housing have to be on it before it will power up? Because i recently purchased a LCD + Digitizer combo and watch the video on how to fix it and did. Now when i go to power on my HD2 without the back housing on it just vibrates and no screen turns on?! Can anyone tell me what maybe the problem =)

Check the wiring again.

Changed screen and digitizer. Touchscreen working but screen. Help!

I followed Android Centrals guide to change my broken screen on my Nexus 7. Sadly, the screen won't come on. I can hear that it powers on. I power it on, touch where the back button should be and I can hear that it recognizes my touch but the screen doesn't come on. Can anyone help or direct me to any solutions or ideas? Thank you

There are two cables from the screen assembly to the mainboard. The flat copper looking cable is the digitizer and the other cable, with a plug on the end, is the screen. Make sure that second cable is plugged in tight.

Black Screen

Hi
I'm a long time note line user and am thinking of getting a used note 10.1 2014. I'm concerned about the black screen issue I've read on Amazon reviews. I checked out a review unit a local t-mobile and it had the same problem. Is this really that common? Is there a way to safely get a used one? Thanks for the help.

@swid441 Black screen issue? You backlight bleeding?

Not back light bleeding. It's the issue where screen goes and stays completely black. Tablets is on and capacitive buttons work but no display- all black.

I've had that happen to me after I dropped mine once...with 2 cases on. Anyway, to fix it, I just open up the back and reconnected the screen, very easy to do, I think it jarred the tiny connection. The tablet is so awesome otherwise and it might never happen if I hadn't dropped it

Edit: I popped the back cover off, unhooked the LCD ribbon cable and plugged it back in. Put the cover back on and tried to power on. Nothing happened. Not even the soft keys lit up. Plugged the power cable in and tablet came on like it never had an issue. Glad I found this thread before I spent $150 on the LCD and digitizer.
What did you use to open up your Note? I rebooted my note the other day and the screen was black. The buttons light up but the screen is off. I want t to try and reconnect the cable before I but a new lcd and digitizer.
Did you open it from the front or the back and what did you use?

If its still showing black screen, keep reconecting, smoothing the cable oit and pressing the un sleep key to see if the screen is on. The cable is so sensitive it takes me about 6 tries to get it perfect. I use whatever I have around to open it, like my thin nail file, very carefully, around the silver edges from the front. I remember I saw a youtube video of this somewhere. Good luck

Screen replaced cant disable backlight

I broke my phone screen digitizer/LCD/frame and replaced it with ebay one.
My phone booted up and working good but i cannot to disable the button backlights next to home button. it worked like a stock phone, my phone rom and 3rd party software has no control over backlight. any idea what i've missed ?

did the light turn on even on boot screen? if so, check the connector of your button. maybe there is some dirt or something on it so the electricity don't work properly.

Probably a bad connection of the sub key connector or a bad sub key flex.
Somtimes the soldering quality is very low

I have this happen to me daily lately, usually for me my phone reboots and screen is back up, but I'm worried it won't come back one of these days unfortunately. My bottom keys light up too, but screen just goes black. Occasionally my screen comes back on its own but usually needs a reboot
