Hello Everyone!
So i'm really stuck over here. I have an international Samsung Galaxy Note N-7000 that is working but with a black screen!
First of all i want to discuss exactly what i have done:
1.i had a problem with the charging port where it works sometimes and most of the times doesn't. So i decided to order a new charging port to replace the existing one.
2. When i received the new charging port i instantly started to dissemble the device (The device was working perfectly before starting replacement)
3. After i removed the old one and installed the new, i turned on the device and it showed only a black screen, then after some time i saw the touch buttons light, but still the screen is black:crying:
4. so i decided to return back the old charging port and this time when i turned on the device it sounded like it's booting and working but still with a black screen. The phone even received call and the touch screen is working but with black screen.
What do you guys think has just happened to my phone? could the new charging port cause any problems with the motherboard?
i'm really stuck and don't wanna go to a service center
I have recorded a video of the problem. Please see it below
since i'm new over here, i'm not allowed to post youtube link.
please head to youtube and type my username and watch the video : nadeaa0a
thank you very much
My younger brother always liked to disassemble things with a hammer wondering after why it wasn't possible to assemble it the other way around.
It took him a few years to understand that real knowledge of things is a clear advantage.
Go to a service center and get help from a professional instead of making it ...

maybe you disconnected the wire you were changing ports ! don't worry and don't freak out just take to any shop and they will check it i don't think the screen is burnt because if it was it would be more expensive ! go to any shop and ask them to change ports and check the screen
for what you described, my best guess would be either you unplugged the lcd and didnt plug it back in properly.... or you damaged the flex for the lcd... the charging flex wouldnt cause the problem... just inspect the lcd flex and plug for damage... if no visible damage plug it in again and try it again... lets hope its just not plugged in right...
I have the same problem
Hi,
I have the same problem. I had never disassembled my phone and the screen slowly turned purple and started blackening out. It was fully functional. This I knew because I connected it to my Windows 7 computer and used Android Commander. I ordered a new screen complete with bezel etc. I have two batteries, the first didn't even charge after I put it in the phone (it had drained totally during the wait for the new screen), the second was partially charged and allowed the screen to boot. It is however behaving like the first screen did before it went black, that is purple. I am sure I have not done anything wrong with the connections. Could it be the batteries? or the adapter flex? I just hope it is not the mainboard. It is not on warranty and we don't have that many honest phone specialists around where I live. I am almost sure others have experienced the same problem and someone on xda knows what the problem is. If you do I would be indebted.

it shows as color black, or nothing (like locked device)? I used to face this problem too with my infuse 4G, but it was because of installing custom rom. Had problem with few rom i installed but nothing happen on my stock one. If your device is just not lighting up(like locked device), then i guess because of ROM, but i'm not sure yet. But if it shows "color black", then i don't know.
THIS IS NOT A SOFTWARE BUG. Its the Screen flex or the ribbon. Disassemble the back part, and take a look at the flex or the ribbon connector of the screen, clean the conector with a tooth cleaner with alcohol and let it dry for a few minutes. Put it back on and mount the back part again. Test it, it should work.
Same thing here: changed the usb port, booted fine, had issues with the sim, turned off took it apart again to check, put it back on and black screen.
Yea having the same issue here, dismantling the usb module and put in new one, power up black screen!! The menu and back button did lights up, and the phone is working too, can hear the booting tone, anyone got any solution for that yet?

You damaged your LCD flex cable or didn't plug it in correctly ..

I have unplugged and replug back few times, same result. Guess most probably i have damaged the flex cable. Replacement part seems too pricy to change, rather buy a new phone.

Hi i have had an x1 since august but within a month its been dropped and then it was unable to show the screen, i opened my device to try and fix my problem but messed with nothing whatsoever, when i put everything back together it wouldnt even turn on anymore! all it did was charge and when it was fully charged there was a red light. can anyone help me? please im desperate to fix my phone. My first paycheck was spent on this and i loved it despite the numerous flaws! also i havent charged it in over 2 - 3 months. Also when i opened it the tape that connect the rear and the front is kind of messed up, would that effect anything?
The tape that connects the front and the rear is the cable for the screen, so if it's messed up, you might need to get a replacement.
here is a pic, the red part where its circled is where i think the problem is, it looks ripped off, i did have a hard time opening and putting it back together the first time also.
Sounds like (Or rather, looks like) you're screwed, as far as I can tell, if it's really ripped. Otherwise attempt to clean the contact points with some cleaning alcohol and Q-Tips - something might have made it's way in when you disassembled the unit and blocked the electrical signals.
ill try it, but if that doesnt work, would i be able to replace the flex ribbon? would acteone work?
got this checked out by my friend, he told me its the flex ribbon cable, thanks for the help btw. Does anyone know the cheapest place to get a flex ribbon cable from?
Still would like confirmation if its my flex ribbon cable before i spend 40 bucks on a new one. thanks!
Hi, I am new to this forum. Sorry for posting here but I think I have similar or same problem with my xperia. Few days ago I drooped my xperia and then I could not turn it ON. I opened unit, the flex cable was detached.
After attaching the flex cable. I could turn the unit and it booted normal but no response on touching screen I even tried to align it but it did not respond. I turned off the unit. After trying turning it back ON only back light of the screen turned on (no sony logo, no xperia logo no winmo).
I tried to turn it on few times but same result. Even tried to soft reset and hard reset it but no difference only back light. Is it because of flex cable or because some thing else? I can`t even go in to 3 color screen. Please help. Sorry for my bad eng. Thanks.
Hey dear friends
2 days ago my phone failed to the ground from top my bed and got wrecked
My phone's LCD show nothing except that a black screen with a little light
I think and I hope it's from that cable that connect contacts of LCD to main board I think it called Flat or something else.....
I disassemble it my self and I wanna to show it to a mobile service center tomorrow....
anybody have any idea about this issue?what's the problem?
Before you start considering taking it apart, try plugging into your computer first.
I know it sounds daft, but after I dropped my phone last summer, when I tried to turn it on you could see a slight change in the shade of black, yet nothing would show. (Implying that the screen was still powered in some way, but just didn't display anything)
I'd just tried to plug it in to get the data off it before sending it away after a few days of hoping it would come back on, and the screen came back on!
It might not work for you, but it's worth a shot!
Last Xperia X1 I had for repairs had black LCD after a fall. It buzzed and started up, but LCD remained black - flex needs to be replaced.

did this problem ever come back?
My Xperia fell today and when I picked up I saw the screen was broken (im talking about the inner part which is the LCD I believe)
Its kinda like this [Seach on youtube "My LCD Xperia X8 Cracked" since I can't post links ] (That is not my device but the problem seems to be the same, even tho on mine its only a small part (just the top edges))
Everytime I turn on the phone now it just shows the lanes then turns itself off.
Is there any way to fix it? If so, would I have to buy a nex LCD? And if so, would it be hard to change it myself? I live on a small town and trusting your device to some technician is like giving away your money.
Thank you ^^

Thank you for the fast reply. Yeah I think I'll try checking my warranty even tho I believe is off warranty already as I have this device for over a year now.. I'll prolly end up changing the LCD however, is it sure that changing the LCD will fix the problem or it might have another broken thing inside there? Today I just tried to turn it on and it won't even turn on now it just pops the red LED when I press the button (I think it ran out of battery, but then I try to charge it and it won't).
Thank you again

I have the same issue every time the phone dies from lack of battery. after poking it a bit on USB (connect it for 20-30 times) I saw that the device sometimes switches on in Flash Mode and after a while, FlashTool wil recognize it and do s strange thing. It allows you to start flashing what you want but after starting to gather device info, it freezes. after doing this a few times (10-15 times) Windows recognizez new device and the FlashTool asks to choose my device. Then the phone reboots and starts up in Android.
Usually this works and phone starts to charge but today after it started it was not charging and the batt level was saying Batt 0% and that it won't last if unplugged. I've left it like taht for an hour but still nothing. Then I decided to reboot the phone from the power button menu and after restart it started charging. It took a while but then it returned to normal and now it works again.
I have this issue only on custom kelners both NAA and ALFS but it's ok on stock kelner...
It would be great to find a fix for this as it is very annoying and time taking just to make the phone start charging...
Actually I charge mine via USB connected to my PC everyday (as its more comfortable) but I tried to charge it with the regular charger plugged in to the wall's socket and it charged.
I guess I'll buy a new LCD and try to change it myself.
HI guys,
I want to post on behalf of a friend who has a problem with his Xperia Z1. He originally bought it used with a broken display, he then changed it with success, the phone was working fine until it fell. At this point the display was still working but not the touchscreen, so he ordered a new assembly from the net (not genuine, like the first one which worked tho).
Upon receiving his new assembly, he immediately started the repair. However, when he turned on the phone, he only felt the vibration and nothing appeared on screen. No any light, he got a totally black display with no sign of life, while the phone was fully charged, and was recognized by Windows (he could even access his files on the memory).
He obviously thought that the seller tricked him and that the assembly was defective but when he tried with the old one (which had the display working but not the touchscreen), the same result showed up, no light, like the assembly wasn't plugged to the motherboard at all.
So far that's what I told him, check the connections to the motherboard, and make sure the flex ribbon is not damaged. He even bought a new ribbon and installed it, with no success.
He read that the problem can come from the display ribbon touching the chassis, thus making a short-circuit, but I doubt it. How if the display connector on the motherboard is broken? Is it fixable? Like buying a brand new connector and soldering it.
Thanks in advance for helping us
Try a hard reboot by Golding vol + and power until phone vibrates. Is the backlight working?

Thanks for reading this long problem
Sure, he tried the hard reboot thing, he even successfully flashed a stock ROM but nothing changed. I can only think of this as a hardware problem, but what part is defective?
The motherboard connector?
The ribbons on the chassis? But he changed to new ones already!
The LCD assembly? Same, the one he tried is a new one...
Still no one to solve the mystery?
I'd like to add that the phone turns off itself after approximately 30 minutes in idle state. That is, the explorer doesn't show the phone anymore and it has to be powered on again.
I know the best solution would be to buy a new motherboard or just forget about this broken phone, but it's a challenge to fix something that is apparently hopeless
Hi
A month ago my screen suddenly went completely dead, the phone it self was functioning normally except the screen, \
so i posted this thread : http://forum.xda-developers.com/xperia-z/help/how-to-make-screen-dead-t3175115
then i decided to tear down the phone, i did and i played abit with the lcd flex cable, i got the screen to work but with very low brightness and a lot of blinking, i played a bit more with the same cable
and tried powering up the phone, the screen gone completely black again so i thought i broke the cable
i ended up buying this
www.aliexpress.com/item/LCD-touch-s...ria-Z-L36h-C6603-LT36-display/1449119790.html
it arrived and i played a youtube video of the device dis-assembly and copied every step exactly, tried powering the phone up and the new screen is black!
anyone have an idea what's going on?

Maybe something not connected, or because it's aftermarket screen. There are lots of screens for sale but I don't believe they all work as good as the OEM screen.

Did you ask the seller to exchange the item? There is always a 10% chance of a black screen when buying a replacement screen.
If you tested the screen by just connecting it to the motherboard,and it didnt work,you should be able to get a replacement for free(but you will probably have to pay for the shipping when sending the broken one back)
By the way. I need to get a new screen replacement(the current one started flickering and glitching after 5 days of usage-I literally held the phone on the desk,answering calls and putting it back on the desk,so I couldn´t have damaged it),but I cant waste money. Was the package in a good state?
If anyone can recommend a cheap,but working screen(I dont care much about the 10% weaker colors,I just dont want the screen to flicker and glitch out),I would be extremely grateful.
