[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] 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 doesn't stay on anymore

When I bought the watch back in November, the screen would stay ON all the time. I know it to be a fact because I used to leave it on a desk without ever touching it (for hours) and it would always display the time (it was like having a desk clock, for when I would rather not wear it to have more comfortable wrists while writing or that sort of things).
Also in the train (I used to travel a lot in that period) I would leave the watch hung on the wall while sleeping (at night) and it would not turn itself off, so I could check the time in case I woke up in the middle of the night, without neededing to reach for the watch.
Recently (it was January) I noticed that it does not work like that anymore. After a very short time, the watch screen goes off. It is still in standby: it goes back on if I touch it or press the button.....but I want it to stay on 'without limits' (in dimmed mode). It was like that before.
Somehow this is the behaviour of the 'keep screen always ON' setting.....but in fact, that setting is already set to 'ON'.
So is there some kind of firmware update that changed this behaviour? I would like the clock to not go off when it is not on my wrist, sometimes I just need to keep track of time AND have my wrists free....and it is not possible anymore.

nothing?
It is actually a key feature....no point in having a watch that doesn't show the time unless you touch it (if you leave it on a desk or simply hung on a wall at night). Also I wonder why it changed (did not do this last year so I thought it must be some update but could not find anything in the changelogs about this).

You have the Setting enabled in Android Wear for keeping the screen Always On?
My screen only goes out when on the charger. When I had a Samsung Gear Live, it would stay on while on the charger, via the Developer Setting on the watch to keep the screen on while charging. But that has never worked for me on the "R", not even last year.

The screen of the watch goes off while charging (although I remember it being different back in October...).
The settting for 'screen always on' is activated. I activated from the watch, from the phone, restarted the watch, nothing worked. The screen goes off after a while IF I DO NOT wear the watch.
No problem if I wear it....that means there is some connection between the screen going off and the accelerometer :-/
But as I said, I need the watch to stay on even if I am not wearing it (working at a desk or similar when I can't wear the watch, I would look at the time at the watch lying on the table). I am sure 1000% it did not turn off before (started in January, or at least I noticed it in January). I read all the changelogs for all the updates and I did not find anything about this.
Can someone also try? My brother has the same watch and his also goes off if he does not wear it. I find this really unneeded. At least they should have put a setting available.

You best option is Wear Charging Widget. It will keep the screen on when charging. Although it does dim a bit, like a night clock in a mostly dark room. It is the only option I've found that works.
I wanted the "R" to work like my old Gear Live and keep the screen on when charging and even when not wearing it. But I've never found a means for that to happen short of Wear Charging Widget.

Yes it looks it is like that now. Maybe you bought the watch after the two last updates (501 / 502) ?
Would be nice if somebody else, besides me, could confirm that in fact the watch was staying on (dimmed mode) all the time even without wearing it in the previous months (release date to December).

I've had my "R" since last year, before v5 came out for the watches. And the "R" never kept the screen on while charging. I never noticed it involved simply not wearing it. Since when I'm not wearing, I'm charging.

Screen shuts off completely
The screen on my GWR has started shutting off, completely dark not dim. I checked the settings and it is set to "Always on screen": ON.
This is a fairly new problem, it did not used to behave this way, I could see the screen dim, and move my wrist and it would go bright and display "OK Google".
Any ideas on how to fix this bug? Or do I/we need to wait for a software update/fix? Current software version: 5.0.2
Watch is not very useful if I can't see the time without having to push the crown/button.
Anyone else having this issue?

Screen is working again.
Had some time to try some options, did a "Reset Device" and the screen came back.
Lost all the apps I had loaded on the watch, not a big deal, wasn't using many of them.
Guess I can just download them again from the play store, if I want them back. Something I loaded onto the watch may have caused the loss of the screen.
Last couple of apps I downloaded were CompassX and a charging app that shows charging progress while charging.
Glad to have the watch face back.

I'm having the same problem as you. The ambient mode won't come on. Instead of dimming to ambient mode it now just goes dark completely (like when it is charging). I would love another fix before I have to reset the watch. Any ideas?

Bumping this. I reset the watch. Went about two weeks and now back to the same problem. Ambient mode has disappeared. It's just black all the time until i turn it back on.

I confirm that I have this trouble also in normal use, previously it worked fine and would stay on all the time if that's what I wanted.
Am very tempted to reset the watch after backing up.

I have nearly the same problem. For months now, when my screen dims, it goes to a very dark/dim red. I've removed all programs from my phone and did a factory reset on the watch three times. I'm not sure what else to try. Is there a way to flash the memory? It seems like a setting is stuck in the non-volatile memory.

I was having the same problem and found that I had theater mode set on. Switched to off and now works great.

Check your theater mode setting.
Turning mine off worked.

I'm experiencing the same. On my watch it seems to be somehow related to accelometer. Almost everytime, when using LG G Watch R in golfing, it starts to shut down the screen. It doesn't wakeup even when tapping the screen.
I haven't found other solution than resetting the device

Same issue with 5.1.1
I had this issue with 5.0.2 and hoped that the next update would solve it but sadly it persists in 5.1.1 .
Theatre mode is off, Always on is on but still the screen blanks, showing the ambient mode screen briefly before blanking.
I've reset multiple times, occasionally Always On comes back but only for a short while.
Always on is a feature I really like

Fixed it on mine
I had to turn wrist gestures on. With it off screen on doesn't work.

I have the exact problem on my GWAR, software version 5.1.1. I bought my in December and it never happened until now. It started happening yesterday all of a sudden. I tried factory reseting it through bootloader, throught settings, uninstalling the Wear app, uninstalling the watchface i was using, and still nothing.
Here is what I did to fix it (and i know its overkill): Uninstall Wear app, clear google play services data and reset the device through settings. Now it's finaly working.

Weirdest black screen issue, tried everything ....

Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?

I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

Tried it......nothing.....warranty job it is.... Bummed to have some refurnished phone in exchange for a Brand new 900 dollar phone just a few months back?

Yeah that sucks, i can imagine..... i too hate the idea of refurbished units being swapped for warranty....bs, should be brand new unit!

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).

This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.

I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.

same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.

I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.

I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.

I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.

Help! Black screen on restart

Hey guys,
I had an unfortunate accident where my phone fell in the toilet...
It kept on going ok for the first hour or so, but after a while it went crazy, self switching between black screen and the homepage
Ultimately, it is stuck on a black screen mode - where you can see the clock, weather and date on the upper-middle right side of the phone, as well as the number of steps who is still being updated. When I connect it to the charger it shows the battery status.
I have tried to restart it a couple of times, but after less than a second where my homepage is visible, it switches back to the black screen.
I can receive calls (it looks little of the screen, I can use the touch screen to answer/decline the call) and I am still connected to the net as the whatsapp on my computer is still on.
How can I fix this problem?
I bought this phone in China in Oct 2016 and it was working ok until now.
Please try to help me...
Thanks guys!
