[PROBLEM] Died?

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?

[Q] My screen stays off when starting the phone. Help needed.

Hi, I've been having this rare and random problem with my Captivate. It seems like once or twice a month, when my phone is in stand by and I hit the power button to wake it up, the screen stays off. I can mimic swiping the screen and the soft keys will light up and the phone will vibrate. Taking the battery out does not help. The phone will boot up and I can hear the att and samsung video but the screen is still black.
When this happens, it will sometimes randomly come back on after about an hour or two, sometimes more. I've searched but haven't found that magic trick yet. Anyone else have this problem and a possible solution? Any help would be awesome, thanks!

Sounds like a hardware problem. Still under warranty?

Yeah, it's very annoying. I can hear texts going off with seemingly no way to read them. I've had it more than a year so I think the warranty is out. I do have insurance on it though.
EDIT: Ok, my problem is solved for now. I took the sim card out and with it out turned the phone on (same problem), but after turning the phone off and putting the sim card back in, I now have the screen back. I'm gonna see if I can get this phone replaced.

[Q] Phone works, screen does not yet sometimes it does

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. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

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.

[Q] screen going black when making or receiving call / camera no longer working

using HTC Google Nexus One, Android 2.3.4
This is very strange, but I noticed today that my camera is no longer working. I have no idea why, but it just goes black when I select camera. I have restarted my phone, took out the battery, etc. and nothing. Also, I even tried downloading other camera apps, and they won't work either.
Even more frustrating, though, is that my phone goes black when I make or receive a call. The calls do not get dropped, but when the call is over, I can't even hang up, as my screen is black. It's weird because my phone is still "ON," but I obviously can't do anything. The only thing I can do is take out the battery, put it back in, and turn the phone back on. Then, it works perfectly normal...until I make or receive another call. I have no idea what to do.
Can anyone help? I'd really appreciate it, as I use my phone for everything!

Hi,
I had very similar issues after accidentally dropping the phone (landed exactly on its face) . The sensors no longer worked, nor the camera and the flash light.
The problem during the phone calls is most probably related to the defect of the proximity sensor. However, I managed to use the phone with a bluetooth headset. The screen could be turned on any time, and, of course, I could terminate the call using the headset's hardware button. I used my N1 this way for over a year...
Few weeks ago I dismounted the phone, and realized that upper motherboard's connetor was detached from the main motherboard. After fixing it, everything is fine again.
I followed instructions from here: http://www.ifixit.com/Guide/Installing+Nexus+One+upper+motherboard/8025/1
I hope it helps.
Cheers,
Zoltan

Thank you for this thread
I created an xda account just to post about how this helped me.
My Nexus One camera had stopped working, auto-rotate no longer worked, and my screen was remaining dark after completing phone calls. So annoying. Was about to pony up some money for a new phone.
BUT... I followed the ifixit instructions that Zoltan posted above to take my phone apart, and low and behold, I had a loose connector. Plugged it back in, reassembled my phone without breaking anything, and it works! I have camera and auto-rotate again, and my screen acts normally when making phone calls.
Thank you!

Black Screen

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
