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?

About a month ago I got my Kaiser screen replaced as it was broken, now all of a sudden the screen is all whitish and I can hardly ready whats on it!
Is the screen broken again??
I'm fixing to replace the screen in a Kaiser i bought used with a broken screen. From the reading i've done, it sounds like one of the cables to the screen is loose. Trying pressing on the middle of your keyboard and see if anything happens. The big ribbon cable has a connector there.
hmmmm coming to think of it when I pressed the middle of the screen it used to do some funny effect (like when you press your TFT monitor) but now nothing happens!
Is your screen something like this?

Click to expand...
Click to collapse
last night i was woken up by a text, i looked at my phone and all of a sudden the screen went crazy. Started scrolling up and down (like a bad signal/wrong format ntsc/pal on a tv). Everything got all messed up and lines and dashes all over, kinda like your screen, it started acting wierder when i began applying pressure on the top of the device by the earpiece and d-pad. So i soft-reset the device and it was still doing it while boot up, leading me to believe it wasn't a software issue.
So in my half awake state i just left it on my nightstand. I woke up and its perfectly fine now, even when i press all around the screen.. wierd huh?
I didn't notice anything like you descriped, touch screen and everything else worked like before. Only the colors were like on the picture. Tried hard reseting but didn't help. Phone is still under warranty so sent it to be repaired, i can post what they did when i get it back.
Thanks jrask. Thats exactly how it looks.
I think i have some bad news for you, the screen was damaged and needed to be replaced. I think it was cracked under the frame.
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.
I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.
So I recently cracked the screen on my HTC One m7. I bought a replacement screen and front housing. The screen was so far beyond repair that I couldn't shut off the phone prior to starting the replacement. I tried waiting for the phone to die but after two days I became impatient and did it anyway (essentially the phone lost power when I disconnected the battery). After transferring all parts into the new housing and being what I though as diligent putting all parts and connections back in their place, tried to power the phone back on. all that happens is that the back and home buttons flash and then I hear what sounds like the audio for when the phone powers on. The screen stays black and then phone doesn't technically turn on. I know this because I have missed messages and the green led light would be flashing if it was. Therefore, at this point I'm not certain that the new screen works or if I've connected it right. I've tried the numerous boot tricks with the volume buttons, nadda. I have had the phone on a charger for a full day and the same problems. (Disclaimer: I don't have the original charger, but I have been using this one for a long time). I do see the red charging led if I wiggle the charger in the input, but also just recently I saw a green led when doing this, which when the phone was working was a sign that it was fully charged. If anyone has a solution to my problem that would be great. I'm also interested on what's wrong, why this is happening, what might have caused this behavior? What do the flashing home and back buttons mean?
Howdy,
I've had the same problem, but my phone was shutdown allready. When I replaced the front screen, the phone won't boot. I would like to know if its anyway to get the files from sdcard down?
Thanks for the support!
