I tried to replace the front glass, (not very successful). I got the front glass off, but the LCD was still stuck to the screen, even after heating it up with a hair dryer. at first, none of the buttons except for power and VolUp and VolDn were working, so I took apart the phone completely, (MB, and screen/bezel assembly as one unit) and noticed that a connecter came loose on the touch screen link to the lower buttons. I got the home, menu, and back buttons to work again, but I still can't use the touch screen at all. It simply doesn't recognize input. Is there a way to fix the touch screen? It displays everything fine, but input via touch is now impossible. Is there a connecter that I may have missed? I would like to not spend $71 if I don't have to buy a new front screen/bezel assembly
You have a hardware fault caused by overheating the digitizer, replace the hardware.
It's quite common after screen replacement, which is why the screen assembly is the sold in one piece.

Well, now that I tore it apart again, and put it back together, the phone won't turn on at all. ****. Now it looks like I'm going to have to buy one. I'm now back to my backup phone, which is a i997 flashed with CM11 (unofficial) 4.4.4. Do you think I EMPed it by accident? Even plugging it in, it won't signify charging at all.

So, being clumsy, I left my Streak in my hoodie pocket. Well, we can all see where this would end badly once I bent down to pick something up. I did, dropped my phone and cracked the screen.
I quickly went and bought a replacement glass + lcd display, and replaced the unit. But, upon turning the phone on, I noticed if I hit it a little too hard on one corner, It would restart, and the vibrator motor had ceased to work.
So I figured, hey, I'll just rebuild it again. So I took it apart. Looked through everything, took my time in putting it back together, because maybe everything wasn't fitting snug.
Now, When I turn it on, every thing is on, buttons light up, and the screen is lit up, but it is black. I never even get to the Dell logo. After about a minute the buttons dim, as if in idle. So i believe the phone still works, but maybe the connections on the MoBo is faulty? Any help would be nice, thanks.
check to see if the ribbons are snugged in place.

I agree take it apart and chech your work. I had problens with my camera and flash. It was tge connector not being fully seated
Sent from my Dell Streak using XDA App
Well, I just took off the rear cover and reseated all 3 connections, pushed em in as smoothly and far as they would go. But, same thing. Black screen. But the LED is still working...
I'm having the very same problem. This is my second replacement screen and neither displays anything except black screen with backlight on, and the home + settings + back buttons remain lit. I can hear my phone starting up and receiving messages, but I cannot see anything. I've taken the phone apart and put back together five times between two replacement screens.
Does anyone know what ribbon cable might be at fault for this particular issue? The largest ribbon cable was shipped bent across the circuit board on both screens; there is a permanent creese in both ribbon cables, but I'm not certain this is causing the issue.
Any insight or assistance with this issue would be greatly appreciated!
So dropped phone and screen went out. Replaced amoled and digitizer, device powered on and lit up home keys, but no display still. Replaced main board, in case video was out on board, but no joy. Any thoughts? No custom software or anything....
Maybe you didn't clip on the ribbon cables all the way. Or, just try pulling the battery and booting it again.
When I replace my screen, screen didn't work for first few boots.

I checked and checked, digitizer works, I can reboot and swipe unlock, adjust volume, but no screen. At this point I'm thinking bad LCD. Thoughts?
Thx for response and ideas though....
I bought a replacement but ut was a cheap fake, not an OEM screen. It went purple then black within 10 minutes. I got my money back (thank you PayPal) and made sure the next one was an OEM screen.
I hope you didn't spend too much on the repair parts. You can pick up a new Note for about $290 now.
Hi,
Trying to fix a Z2 for a friend. She dropped it, smashed the screen. You could still see the LCD, but the digitizer was fubar. Ordered a new screen assembly, but after the replacement only the LED backlights work - no LCD at all. To test, I reinstalled what was left of the old screen, and no LCD, just backlight, so I don't think it's the new screen. So then I ordered a new main ribbon cable and replaced it. Same result: no LCD, just backlight. You can hear the phone on when it's on, the phone "responds" when you touch the screen, you just can't see anything. I upgraded to the latest software update tonight using PC Companion, but no change.
So, the only thing left is the motherboard, right? I know there is a fuse on the motherboard that, when it fails, it kills the backlight and leaves you with only the LCD. I have the opposite problem. I'm hoping maybe there is something like that for the LCD??
Thanks in advance,
Heath
I have same issues with you and also try ten new lcd all show backlight only..what your solution??
Have you tried to connect it via a MHL cable to TV ?
While using my gs4 i545 the other evening I noticed my screen was half working and half black. The phone was never dropped. After powering the phone off I can see t
cracks across the screen from my power button to the volume button. The phone still powers on but the screen is completely black now. My question is, do I need to fully replace the lcd along with the digitizer or just the glass? No liquid appears to be leaking. I have broken a screen before but it continued to work, this one does not. I do not wish to send the phone back for repairs as I have files in the internal memory I need to recover. Thank you for any advice.

Ive replaced a couple of them and found the best/easiest way is to get the screen/digitizer frame assembly and change it out yourself.
Where I get parts from the screen is currently $110
Hey guys, recently I had my Z2 sent to a service shop because it wasn't turning on or charging. The guy at the shop said that it was the battery fault and he changed it, but he also told me that the screen was not working( flickering, ghost touches, unable to work on it). So he put my old battery on and when I went home the phone actually turned on and booted up, but still I had the screen problem. So whenever I touch the screen it doesn't respond and it touches by itself. Tried putting it on rice for 20 hours, dried with a hairdryer and assembled dissamssebled the screen jacks, still the problems wasn't fix. Do I really need to change the whole LCD or is this a problem that can be fixed?

Yes, you have to change the screen, or more precisely, the digitializer.
But since the LCD and the digitialier come in one-piece, you have to change it as a whole, but at a much lower price, as your screen can be sold again and recycle the good LCD panel.

So replacing the LCD would fix the problem right? That's great then because I found an LCD with a very low price (20$), completely new on ebay and I sucessfuly dissassembled the old LCD out of the phone. I'm gonna buy it as soon as possible. Thanks man.
