Hello!
I have a LG Optimus Black , and the touch function of the screen is not working anymore but the display shows a normally image at startup and I don't know what can I do except flashing it's firmware.
Can you give me some options to repair the device? The screen isn't broken, when I taked up from the computer's table, doesn't react anymore ( and I found the battery discharged )
Thank you!
Even after a reboot(battery pull) it doesn't respond?
You should take it to a service center.

Maybe there is a problem with the ribbon cable connecting the digitizer to the mainboard. I once saw this on my former Galaxy Ace. Since this is very tiny I would also advise you to take it to repair center - I broke my Ace when I tried to fix it myself...
I had had this problem too and I took my phone to service center,
they replaced the screen.
It appeared on my phone without reason , it's really a strange problem.

Hi, i'v got a problem. I tried change my digitizer and, when im done, now lcd doesn't work, because it is still white...:/ What can i do now? any solutions?
Thanks a lot
Check your connections. Pull apart and re-seat everything to ensure everything is hooked up good.
everything is fine :/ still white screen
Perhaps you zapped or damaged the LCD when you were working on it...
You could try replacing the LCD too -- but at this point I think I would send it to the professionals
HTC repair or someone like PPCTechs
Don't know if the screen set up is still the same. But when I replaced the screen on my Universal the wiring for the touchscreen was stuck down onto the lcd wiring, as they both shared common earths. Maybe worth a check before spending more cash?
i have the same problem, the screen was working fine before i replaced the new digitilizer and now its just white but i can hear the tablet playing so it must be the screen.i checked all the wiring 4 times now! any idear???
:crying:
Slide the phone open and apply some pressure near where the angle of the opening is (back of the LCD below the SIM, where there is a bar). I had the same issue and this fixed it.
I have had my Milestone for a while and it is out of warranty. Recently a narrow strip on the right side (when held vertically) of the phone has stopped responding to touch. It has decommissioned the search softkey, the backspace, L and the P key of the keyboard.
However, I have noticed that the touch response on the left has increased. For instance Q, A, and Z keys respond even if i touch the black edge of the screen, this goes for the back/return softkey as well.
This leads me to conclude that somehow my phone's inner working's alignment to the screen has been disturbed.
I have tried several roms...CM7, Froyomod and stock froyo but the problem remains.
I did use a third-party car charger once that gave me the ghost screen issue. Draining the batter to 0 with the app Battery Refresh and charging it to the full with Milestone charger solved the issue.
I'm in Bangladesh and there is no moto here...there is no support and sending the phone abroad for a fix is not an option. I'll have to fix it myself or save up for a few months to buy something else...not a bootloader locked moto again.
So, any suggestions? or directions I should be going or looking at?
1. The ghost touch appeared for me, too, after flashing FroyoMOD. I left the phone for ~a night slided-out, without battery, micro SD, SIM etc ) and it worked fine for ~5 days. Then, the same right side stopped working. We don't actually know what is the problem (moisture, bad charging, wear of the flex cable, defective digitizer) and we also can't be sure if we replace the digitizer the problem won't appear again. So, I suggest that you should sell the phone.
2. You could get an i9000, an LG 2x or a Desire HD.
L.E. I'm 95% sure that this isn't a software issue, so flashing different ROMs wont help.
same issue...
solution: dumped stone, got galaxy (Y)
My milestone eventually died. No M logo even. Thinking about getting a Huawei U8500 as an interim phone before I get something good.
Try Iphone insted
Once I got the same problem, it was not on the edge, but the middle of the screen & U, J & N keys stopped working. It was under warranty so I got the things replaced.

I apologize if I this is in wrong section...I'm new here.
I have a N7000 that had a broken screen.I bought a new screen (whole assembly:screen,frame,pen sensor)....When phone is turned on menu and back buttons light up,and judging by the sounds phone boots up.Battery can be charged normally (phone heats up normally),PC see's it as mass storage device (can't connect to Kies,but I see it's a common issue),I can browse through phones folders on PC etc....problem is that I still don't have any picture on screen,nothing happens (black screen)....buttons work,screen reacts to touch (buttons light up when screen is touched)....but no image.
Also,when I disassembled the phone,I saw that some bright guy (previous owner?) had pulled (broken) flat cable from the main camera....so camera is disconnected.
What could be causing this screen issue?Could it be that I got a faulty screen (considering my luck lately,I wouldn't be surprised)?If it is a motherboard issue,would the phone work at all?
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
