Hello all, so recently I dropped my phone from a decent height, but it worked fine that night, and even the morning after, didn't even crack.
It started acting weird and going black when I would swipe down my notification menu, and I'd have to restart the phone each time, but if I got rid of those notifications it would work alright for a couple of minutes and go black. After restarting it a few times the Samsung logo didn't even show up anymore and the display hasn't come on since then, even in recovery mode. I can hear it booted up, and have even plugged it into a DeX dock to use it, and that works fine, even the touchscreen, just no display. I've flashed the latest software onto it using Odin, and still nothing.
So, my question here is: Could this possibly be a software issue? Or does it seem more like the display was damaged in some way or another, (or even possibly came disconnected from the motherboard?)
I appreciate you reading my post, and wish you all the best,
Briggs

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!
Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys
Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though
Looks like a faulty connector?
Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance
Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]
Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you
actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.
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?
Hi,
Have not posted in here in a while but i'm having a huge problem with my HTC one M7.
Had the phone for a year now and suffered a problem with it once before. The problem before was something to do with the phone locking itself and required me sending it off to HTC to repair. It kept bootlooping and wouldn't allow me to do anything at all.
This problem hasn't occurred since repair however last week the phone was working fine until the next morning when i woke up. My girlfriend used my phone to send herself some photo's and then put the phone on charge as the battery was running low. When i woke up the screen stays black and wont allow me to do anything. If i hold the power button the bottom two lights flash and i can hear the phone booting itself back up. I have a feeling the phone works since everyday at 6:15pm my alarm goes off and i am able to deactivate the alarm by swiping up (i remember the location of the dismiss function) it would appear i'm also able to receive calls and texts since i can hear my message and ring tone going off however cannot see the screen.
I have tried a few things such as holding buttons to reboot, shining a light onto the sensor during a reboot and fully charging etc however nothing.
I should also add i have a slight hairline crack in the screen which occurred about 9 months ago but didn't appear to affect the LCD at all or the digitiser either. Any help would be highly appreciated or any tips on stuff to try.
more information available if needed.
Many Thanks
Kris

It looks like you tried all of the usual methods, sorry but it might just be the screen is shorted.

I thought as much, i have ordered a new screen and once its delivered i am gonna attempt to fit it and see what happens, thanks for the reply.
I have a strange problem, well a few. If I lock my phone (C6903) using the physical button I can't unlock it again. I try for about 5-10 minutes sometimes and it just wont work. If I hold it down I can feel it vibrate as if it's bringing up the power menu but the screen just stays black. Eventually it will randomly wake up then I can play around as normal. If I leave it to lock itself I can unlock every time, fist time no worries. This is what pointed me to it being a SW problem rather than a hardware problem.
I also noticed that when I do have the screen turning off in the dark, I can see that the screen is still lit up! Just it is black, not completely asleep. It's really quite bright when I have it next to the bed. Also when I am outside I can't see the screen at all really, even with the brightness turned right up.
It's really strange all these happened about the same time. I figured maybe it was a ROM problem and a fresh install of stock ROM would help. Tried it and at first most of these problems went, just the fact I still couldn't really see the screen in the sun. I tried another ROM and at first was just the same but then these problems started again.
Has anyone had any or all of these problems or got any ideas what it could be? I am left thinking now that the problem is more likely hardware related as the problems are so sporadic and happen whatever I have installed.
Any help / suggestions would be appreciated but I have the feeling I will have to just admit the phone is dogged
You say that most of the problems desapararecen to install a new ROM, it is likely that installing something extra to be the cause, I was introduced me something similar with Expoxed Notifications Module.
Try a clean installation without installing test applications to determine if the problem recurs.
Thanks, yes I guess I will try that, bit of a pain having to reinstall apps after every install and restoring messages etc so I might just put up for now.
I also have realised that the screen not turning on and the screen staying on but black happen at different times. i.e. I can now randomly turn the screen on and off no problem (don't think I have installed or deleted any apps or changed anything), but the screen stays awake when off. When I was last not able to turn the screen back on after turning off the screen actually went to sleep. Very strange
