Originally my droid was showing some screen tearing when opening and closing the keyboard, and then this progressed to the screen being blank black when opening and closing the keyboard, with numerous presses of the lock key for the screen to display anything. Now, there is no way for me to view the screen. The backlight is there, the phone still works because it vibrates when i do the unlock gesture on the homescreen, but i just can't see anything. I've tried over nine thousand battery pulls. Is there a way to know what's wrong?
Looks like broken flex cable connecting display panel with keyboard part.
So I googled and found two parts

htt p://ww w.flexqueen.com/flex1.html
Would the damage be obvious to me if i open up my phone? otherwise how do i know which part to get?
It has to be the 2nd one as that is the one which connects to your screen.
On youtube there are some good vids showing how to dismantle the phone, you will need a plastic unclipping tool

Hello all.
So, long story as short as possible:
My Tilt got run over, LCD screen was busted but I could still make and receive calls by sliding it open, hitting the call button and using the keyboard to dial and 'enter' to connect.
I was also still able to connect to the phone via bluetooth from my mac, as well as syncing it on my PC partition.
Eventually, I think I hit too many random buttons and turned the phone off or something as I could no longer get it to dial out this way. I was always getting the flashing green and blue lights though.
After some research (and un-won auctions on eBay) I decided to see if popping in a new LCD screen would fix my situation.
I installed the new LCD last night, and the machine is almost back to living, however, I now have the current problems:
When the phone boots into 'normal' mode, the screen is display is very truncated. It doesn't display the full HTC updated today screen and won't respond to touch. It says 'no service' but wi-fi seems to connect. If I slide it open, the keyboard lights up but doesn't respond, neither do the front keys. Also, I get only a solid orange light in the upper left LED.
If I boot the phone into 'Safe Mode' it responds to touch, connects to the AT&T network, connects to Wi-Fi, etc. The front keys still do not do anything, and when I slide it open the keyboard does not light up or respond. Also, I get both the green light in the upper right and blue in the upper left.
Another thing, when I slide the phone open and closed there's a slight ripple in the middle of the phone like something is 'pressing' on it from the back.
Sorry for the novel. Any help is appreciated. I'm considering 'clearing storage' and returning it to factory settings or flashing the ROM. I've taken it apart and put it together like four times now, checking, double checking and triple checking connections.
Thanks!
Sounds like one of the headers isnt fully seated in the display region. IIRC there are two that I had to deal with with my 10min LCD swap routine
Yeah, I think you're basically describing symptoms of having put the phone back together wrong except that it's interesting it responds in this 'Safe Mode' and interesting that it would happen after four retries
It's probably going to need a hard reset then! You might want to check nothing has been bent, warped mountings/plastic could be the cause of the screen ripple issue.
Were there any active components on the touch film for the display? (Assuming you have replaced that too with the LCD, or that they're one whole unit) if that is the case, they may be different, newer revisions? Really grasping at straws there though; at the end of the day, the poor phone has been mauled by a wheel... best of luck!!
Thanks for the thoughts! I guess I could try and break it down again. As far as I could tell, everything looked like the phone in the disassembly directions; nothing appeared unduly bent or mangled.
"Sounds like one of the headers isnt fully seated in the display region."
I'll google it, but what 'headers' are we talking about? The small metal bits that seem to touch the upper outside edge of the LCD screen?
Would an improperly seated header cause the other symptoms? Unresponsive other buttons (keyboard, front keys) and connectivity issues with the network?
"Were there any active components on the touch film for the display?"
I got a new LCD and digitizer (is that what you mean by other active components?).
Thanks again!!

Any cable that attaches to the circuit boards, re-seat every one you can find. One faulty connection can cause a lot of problems. I have a similar problem with a button on my PSP but im to lazy to fix it.
most of the time but not always when i slide the phone open the screen goes blank. i need to open and close a few times to get it to properly rotate. is this a hardware issue? how can i fix this. i searched it and others have had this problem as well but i cant find a solution.

Hope your phone is still under warranty, if not you're going to have to pony up cash to SE to fix it or you can try to fix it yourself.
the thing is mine sometimes works fine when i slide it, it rotates normally without black screen. other times when i slide it open the screen goes black, i open and close it a few times and it goes to landscape normally.
I would also suspect the ribbon cable, might be your abrasive wear only just started affecting your phone
are you still on warranty?
Hello,
I have sent my gnexus off to be repaired this week and recently started to use my old milestone until my other phone is repaired. Phone was working fine, a little slow to my nexus but it was better than nothing. I was checking my emails and stuck my phone in my pocket to cross the street, when I pulled it out again, the screen would light up (glow) but the screen was black, I tried pulling the battery and rebooting but to no avail. I can feel the phone vibrate when I slide my finger across to unlock it and tap icons, but nothing is being displayed. I'm wondering if anybody else has had something like this happen and if it is possible to fix relatively easily?
If you don't get anything on the screen anymore I'm afraid it's a hardware failure.
Maybe the connector cable is broken (partially), I guess...
I guess Eiertschik is right.
In the boot process, does the M logo show up?
My screen goes black when I open the keyboard. After I close it, it stays black and I have to take the battery out.
The light behind the buttons on the screen still comes on, and it seems like the blacklight behind the screen comes on. I tested it and if I recieve a call while it's doing this, the phone rings and the backlight lights up, but I cant answer because the screen stays black.
This is driving me crazy...
It's doing this on fresh stock rom and a fresh install of minimoto 1.7
Any idea why this is happening and how to fix it?
This happened to mt xt862. It was a bad or loose flex cable. Had it replaced and the problem was solved.

I thought it was my ROM at first too, but it is the flex cable going out. It gets worse over time until you can't use the touchscreen at all or the backlight doesn't turn on. When I opened my D3 up, there was a clean cut halfway across the cable.
I recommend mobiledefenders[dot]com > Droid 3 > Flex Cable
Here's the disassembly video I used:

You will need a Torx 5 and Torx 3 (i used Torx 4 without issue)
Sorry for the lack of clickable links, I haven't met XDA's min post requirements yet
Anyone noticed something similar?
Sometimes when unlocking phone with the unlock button or by double tapping it wakes up but is unresponsive to touch, the brightness alters with random intervals, wallpaper flickers. The phone becomes usable again after a few locks and unlocks with the button , although very rarely but still sometimes it automatically locks itself after unlocking.
Factory reset didn't help and before that I was using all the latest updates.
Is this a problem on the hardware side?

Pretty sure mine is. It started with similar issues and has only gotten worse. Flexing the phone a bit makes the screen go all wonky and it's the only way I can get it to come on/become responsive. I will more than likely have to send it in to Sony. Ugh.

Idk wth all that means. Some of it I can guess at...but for a phone that was treated rather gingerly...to have behaved in such a manner after X amount of months (7, I think it was, before stuff started going wonky) w/out the screen being cracked or damaged in any way...the answer is lost on me! Hopefully it doesn't happen again.
