Black Screen, phone still works? - LG Optimus G (International)

Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:

(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!

Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.

Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...

Phone got wet, now boots into black screen and no response

Title sums up my problem. I've got a T-Mobile Touch Pro 2 and I've got some water on it a few weeks ago. The wet seal on the battery and phone are both pink. I got a new battery and now the phone boots. It goes through the pink little T-Mobile screen, and then onto the black screen that says the phone wasn't shut off properly and this and that. It gives me the option to press the Volume-up key to do a hard reset, or press any other button to turn off or restart. The problem is that pressing volume-up, or any other key does not do anything. In fact, the only way to turn the phone off at this point, is by taking the battery out.
Can somebody please advise as to what I can do with this phone that is only 2 months old?
I believe the life/fate of your phone will depend on how quickly you acted right after the phone got wet. For instance did you immediately remove the battery and place the phone under a light or in a window where it could dry out? I even here sticking the phone in a bag of rice will help to draw out moisture. But if the phone has sat for weeks I would say it's safe to assume you phone has seen its last days. If you can take it apart and leave the individual components out to dry out and clean off any corrosion with alcohol and re-assemble. I wish I could offer better advice... Good luck it brings a tear to my eye to hear about a touch pro 2 broken down
Edit: Sorry I didnt realize you said that the screen does display. I would definitely try taking it apart and thoroughly cleaning things out and leaving it apart to dry for awhile. sending it in will get you no where (since pink water marks) and chances are HTC/T-mobile wont even send your broken phone back.

You could also try connecting the phone to your pc, and run mymobiler. When the screen goes blank, maybe you will be able to have access to your phone through the program. You could back up whatever you needed, and would tell you if the lcd went out. Just a thought. Sorry to hear about that though.
Mymobiler says that it needs activesync functional in order to work. Activesync doesn't work for me. I tried it anyway and it wouldn't detect. Is there a stock htc touch pro 2 rom out there that is in NBH format so that I could stick it on my SD card?
The very same thing happened to my Touch Pro 2 a few days ago too!
My story is different. I had never had any water damage to the phone. On the 23rd of March, I installed the Deepshining ROM. It worked fine. The next morning, I went into T-Mobile to get the new HTC HD2. I turned off the Touch Pro 2 to retreive the SIM card, and then have been using the HD2 since. I tried to turn on the Touch Pro 2 for a few nights now. It just stays at the T-Mobile Stick Together screen until the battery is dead. I tried a soft reset while it was stuck on that screen, and received the error message just like the OP.
Can someone help me too? I am really worried that the phone is bricked. I can't get a new Touch Pro 2 under warranty since I am running on a custom ROM/radio.
I'm not sure if I can blame Deepshining. None of my previous ROM installs ever failed on me, and people seem to be installing the roms just fine.
Are you trying to conquer my thread? It's nice and all that you've got the same problem, but thread hijacking is frowned upon.
Sorry, the phone is physically damaged. There's not much you can do at this point.
Just as an update. Somehow, after installing the deepshining mod and trying it after a few days, it works fine now. It became very responsive, and I was able to install the original tmo 6.1 stock rom. Everything works fine, the only problem is that some of the physical qwerty keys either don't work or draw more than the needed letter/number. The power button doesn't function to turn the screen off, which really is about the only bummer. Everything works fine. Yay.

Screen died?

Last night I was out and during the night I pulled my desire z out of my pocket to find that the screen was dead, the soft touch buttons were still lit up and working but no display. I pulled the battery and tried to reboot and no luck, you can hear it booting and even unlock/receive calls and txts etc once it has booted up just the screen stays blank the whole time so have to do everything on feel.
Essentially does this just mean my screen has a hardware fault? is it worth trying to fix? I assume the only option would be to purchase a replacement screen and dissemble and reassemble it?
(warranty is not worth it as I live in New Zealand and would have to send my phone back to the UK where I bought it from, also I have dropped it quite a few times so probably voided anyway...)
Thanks in advance for any input
Does it never display anything? So not even a flash during boot or something?
Because then it is probably a hardware problem.
Since the soft touch buttons do still work I think there might be a little crack or something in the flat cable that connects the bottom half with the top.
Maybe you could check whether you can see if the cable is broken or not?
The best thing to do then is to look for a replacement and try to fix it yourself or bring it to a shop where they can do it for you.
No it never displays anything, completely dead the whole time. The touch input is still working though as I answered a phone call this morning on it by making the usual gesture just without being able to see anything. Doesnt seem to be anything wrong with the cable itself as far as I can see. Yea might have to get someone to have a look at it.
My phone is acting the same. I dropped my phone in the pond before, but pulled battery out on time and had it in rice for a day. My phone was still working for about two weeks after that incident. I dropped it and had one little crack at the top of the screen and about a week after that it died when I had a water balloon fight with the phone in my pocket. D;
Do any of you know if the replacement lcd screen/digitizer for the Desire Z would work for the G2?
I had the same thing happening to my G2 screen, only it was intermittently working for a little while, then just completely died and wouldn't work. It was doing this crazy flickering thing then the back light wouldn't go on at all. If I held the phone at a certain angle in the sun, I could see that the pixels were indeed working on the display, but there was no backlight to make them normally visible.
So I purchased a replacement screen from ebay and carefully followed the directions on a youtube video for a G2 take apart. Its not a hard task to take apart and get down to the screen itself. It was rather easy. After putting it back together the screen still didn't work! Sounds work, i can also receive calls etc. But the screen still doesn't work!
Is there any way that this could be a software issue?
Oh and PS, I believe the LCD replacement would work for both the desire Z and the G2. They are identical phones after all right? I'd say its a safe bet. The screen I bought was only 35 bucks. Didn't think that was a bad deal.
Another dead screen or something else?
Few days ago my phone fell of the couch onto a rug - no big deal, so far it has survived much worse, but when I picked it up, the colors were all messed up - overly green and red. Tried restarting - no luck. Everything worked fine, except the colors, but then the screen turned of completely. I could hear notifications, phonecalls, but the screen was dead. After some tapping on the screen, it turned on again - with ****ed up colors. Then started flickering and was gone again. Few more times I could turn it on by tapping before it was dead for good.
Figured, after all these drops it survived, maybe the screen connector is a bit loose. I mean, I could sometime get a contact when tapping it, so I dissasambled it completely, secured all the connection, put it all back tougether and fired up - same thing: dead screen, phone working.
Has anyone had such problem before? Is it screen that is dead, or connector or... I have no clue... I would like try to fix it on my own, with some replacement parts I could get on ebay - but, what gave?

CDMA galaxy nexus - unresponsive to touch

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?
Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.
Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?
Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird
Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random
Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.
mine got fixed by removing battery.

[Q] Red flashing light after screen replacement

Hello there guys! First than anything, thanks for your time in reading this.
This is not the kind of post that "help!! asap! need help NOW!" etc.
I already replaced my wife's phone, but I'm curious what happen to the previews z5 Premium
She dropped the like in a WWF ring. The screen exploded in million pieces. Not just the digitalizer, the image on the lcd was broken too. But responsive some how to the power button and volumen (some parts on the screen shows the image). I turned the phone off, and bought the replace screen online.
I took the phone apart. I did this on a z1 and 3 times on a z2. On those cases I did an neanderthal work. careless. and in all cases works perfectly. This time I read guides and saw like 5 videos, and I did it perfectly. No broken parts, no plastics cracks, nothing, all smooth. I almost proud on what an excellent work I did (btw, some videos shows taking the whole phone appart (I follow them) but I guess its not need to take the mainboard out, and the buttons either, anyway).
I replaced the screen, connected everything, I just not put the back cover, to first test if the phone turn on.
The phone turn on, I see the LCD back light, but no image. After a couple of seconds, the backlight goes off and 5 red lights flash. and then it restart again. (It goes on a loop).
I took the battery off. I did the power+vol+, I use the internal switch to power it off, etc and keep doing the same.
I started on flashmode (it works btw) which is holding vol - a connecting to pc. (screen in this mode is off). I used flashtool and flashed the last oficial rom, first without wiping, second try I wiped ALL.
Still the phone doesn't go on.
Anyone have any idea?
I had the old scren, all braked, I connected it outside to test if the new screen its the problem. But it do the same. just backlight and 5 red blinks
May be there is something that I can still do.
In any case! thank you and have a great day!
Some kind of short is the only thing I can think of.
Hey Code! thanks for your reply. That can be a possibility. When I have more time I will take it aparta and re ensamble it, double checking. But I'm guessing something in the mainboard is broken. May be when I took the mainboard out I bend it too much. I don't know. I will post if I have any progress.
Usually, when the red light flashes and then goes to bootloop, it's a bad kernel, even though I don't really see how it could have messed up here... But I already had my kernel broken for no apparent reason, like the phone reboots itself, and gets stuck in a bootloop with red lights.
I see you changed the Rom, but did you also flash the boot.img? Maybe try another one? Or maybe I'm just really off ^^
Hey @deftoner did you managed to fix it cuz i'm facing the exact same problem as you after screen replacement.
Not yet. When I got the time, I will take it apart and re built it. Just in case that I miss something. I was thinking that may be I bend the motherboard too much when I took it out the first time. Its the only thing that I can think off. If I have any news I will post it here. Please if you can do the same

White and green screen on S20 plus 5g

Hello, I wanted to ask, I was using my normal phone, I blocked it, after a while and from one moment to another the whole screen went blank (if the touch and fingerprint works) it didn't get wet or sticky, hard just like 3 days, on the third day I was using it wanting to cry, the screen flickered and it went on as if nothing had happened (it should be noted that I restarted, I put it in safe mode), but now 2 times a day it goes like this, last night it did it and I don't know It's fixed, I still think it's the software but I don't know, I'm from Venezuela and the screen is too expensive, can you help me?
