I turned on my phone earlier to notice that the screen was suddenly completely white at full brightness whenever it was on, still touch responsive as I can hear it. This is happening immediately upon boot, not even showing the Samsung nor AT&T logos, so I believe it is a hardware issue. Has anyone else had this happen? If so, is there a solution short of getting a replacement? Maybe tearing it down and reseating the connector or something? I don't know, just a bit upset and rambling, sorry
Tore it down and undid and reseated every ribbon cable I saw, didn't help. Ordered a replacement should get it in a few days, might sell the old one for parts to recuperate some of the costs or maybe pick up one of the media docks that does TV out and USB host as well as charging, see if I can convert it to a set top box, assuming the dock will work without any setup on the phone itself

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.
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 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
The camera on my s5 active broke. I bought a replacement on eBay and watched several YouTube videos on how to replace. Unfortunately while removing the screen and sliding a guitar pick underneath the LCD I cut through a small part of the ribbon cable. The video said to start at the top of the phone which I think is a mistake. Anyway, I'm not going to bother replacing the screen as it's not cost effective and I already bought a Nexus 6p to replace it. But I would like to get some things off the phone that I had. Obviously my Google data was backed up just fine but I'd like to get some non Google filess from the phone.
The phone still works and turns on but the display is black. Is there a way I can plug the phone in to a computer and see what's on the screen of my phone. Maybe mirror what is supposed to be on the screen onto the computer?
If it is just files you had saved, you should be able to get them just through file explorer if your phone isn't on the lock screen. If you have a phone repair place nearby, it might be worth asking if repairing the cable is an option. Worst they'll say is no.
I've got a replacement screen that my friend had in his house. Mine was broken (both the display and the digitizer, the latter was acting very weird). I did the replacement myself, and when I was finally done, I noticed something. The Touch Screen wasn't working (I could see the image but no input was recognized). I tried opening it and checking every single cable to see if there was anything wrong, but there was nothing looking broken or out of place. When I was going to test it, I noticed another very weird thing. It actually works if I keep the back of the phone off (not the back interchangable cover, I mean the back of the phone that is screwed in place). The problem is that this phone has a very annoying design that makes it so the Wi-Fi, Speakers, Camera and some other stuff don't function well with the back plate off, speacially the Wi-Fi.
I trully have no idea what is happening or what is causing the problem with the touch screen, and have no idea why the back plate makes the screen act funny. Can someone please help me figure this out?
Perhaps something in the digitizer's flex cable is shorting with the back panel. Try putting a layer of electrical tape between the flex cable and the back panel.
