screen slowly fading (a bit different case) - G3 Q&A, Help & Troubleshooting

If you dont care to reply, dont read. except moderator ofcourse.
tl;dr- screen black. not overheat .. touch works. even after black fading to complete black..d855... no paper/eraser/microwave stupidity..
Before you say its a common thing and is a repeat topic, let me tell you right away, its not..
Description-- D855.
phone screen goes off, more like fades away like some screwed up crt(i can see it going black from the sides and then slowly the whole screen)
when it happens -- anytime. at any moment.
what all i tried-- none. i find the paper logic stupid. i believe that if its such a bad processor, i might as well throw it away and buy anew one. i dont think its cpu problem..
why i think its not a cpu problem-- bcoz my touchscreen works perfectly even when device is fading. in fact at times when i lock and unlock again, all gets back to normal. no temperature related behaviours. it can happen even in a freezer. when it doesnt light up(the screen), phone still remains usable. i infact unlock the device with swipe up and go on home screen and i know where music icon is, and i click and then play cyanogenmod music player ((so use its viper4android even if screen is screwed).
no one mentioned whether during black screen the touch and all were working or not. mine is... so i feel its either the screen unit or the wire that connects it.
woyld really appreciate a proper answer if anyone could help me with this. i mean the word 'proper'/.. if any extra details needed, let me know, i will update. i just wanna pinpoint the thing thats causing the issue so that i can get part replaced if not super expensive. thanks.
PS- my battery has red indicator. like real bad since 3 months or something after it got in contact with water/. no device damage though. last time when it turned red, phone simply used to reboot randomly bcoz of low power for device to consume, but never used to look like some CRT screen slowly fading to black from sides crap.. so yeah.. thanks again

i think its the battery

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?

Help! Screen problem

Hi all
I have a serious problem with my Defy and I'm hoping that someone will know how to fix it, although I think the answer will probably be "replace the screen" or "it's dead".
Basically, only small part at the top of the screen is working propperly. This area, a strip of about 1cm at the top, shows everything as it should. The rest starts black and then a load of mainly white vertical bars slowly fade in down the screen. These change when the screen does, but with a delay.
The touch screen still works fine, and ocasionally the bottom part of the screen will correct itself, but only for a few seconds.
I'm really hoping there's a simple fix to this. Please help me...
Is it drop or water causing this wierd symptom??
It is a must to replace the display if it drop or water damaged.
But if it happen after flashing then it most probably caused by rom issue.
I haven't dropped it/got it wet. The only thing I have done recently is upgrade to the latest MIUI last week, which incidentally was causing battery draining issues, so I was planning to revert to my nandroid.
The problem is, I can't even do that easily as I cannot see the recovery screen. Anyone know how to get round this?
OK, quick update
I have managed to restore my nandroid through a bit of memory and guesswork (remembering where things were in recovery). Initially the screen was the same, but after half an hour it has come back. I hope this means it works, but I haven't moved the phone since, so I am not 100% certain. I'm looking into the possibility of getting an Atrix now, as I have seen them for sub-£200 on eBay and I have wanted one since they came out. Hopefully the Defy will work, and I can sell it and put the moneys towards an Atrix.

Black Screen, phone still works?

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:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(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...

Got an interesting problem.

Hey there. I'm a bit new to this side of XDA. Honestly with how long I've been AWOL from this site nothing is familiar anymore. How time flies. Well my first post back in years couldnt be more unfortunate phone wise, I've had my Z2 for a couple of months now and as a mechanic it's been treated like all my others phones prior, rough. I've been locally recognized as the guy who has a new phone every couple of months because he can't not shatter a phone. An expensive hobby of breaking phones. Well luckily I didn't shatter my Z2. I just water logged it. Gotta change things up right? So here's where the interesting problem comes in, I let the phone sit in rice for 30 hours, switching the rice out half way through. It acted up like you would expect in the first couple of hours but then stopped. When I pulled the phone out I scraped the rice out of all the books and crannies and tried to power it on, to no avail. Dead battery I assume, so I plug it in. Charge icon pops up, a sign of life! How glorious. So I let it sit for a minute as I assume the battery probably dropped below minimum voltage when the LEDs were freaking out. Went back to the phone, held the power button and no screen, but "Hello, Moto!" So at this point I'm convinced the screen is dead, so I force it off with the volume down method and pry off the screen. To find what? More water. Good Lord. This phone is incredibly water resistant just in reverse. So I do the only thing that makes sense at this point, I remove the ribbion connector from the board for the display and put the phone back in new rice as 2 separate pieces. I then leave it in there for another 30 hours switching the rice halfway. Bringing us to now. I took the phone out, cleaned all the rice out of the 2 pieces and off the remaining adhesive and connected the ribbion back to the board. Plug the charger in, and again, charging logo. But then I hold the power button and the TMobile splash screen pops up! Then the screen goes dead and once again, "Hello, Moto!". But whats different is now when the boot sequence is finished I can interact with the phone and it works, shake for flashlight, enter my passcode (just by feel cause I'm good like that, ladies hmu), and the button responds with vibration. The phone is working but no screen. So at this point I'm sure, the display driver is done. I murdered it in cold daylight. So I shut it off and start looking around for new screens, in the midst of this I knock the phone and accidentally hit the power button, and it starts to boot up. T-Mobile spash screen, screen death, "Hello, Moto!", and nothing. Now that seems weird. Why would it work twice on the TMobile splash? So I decide I'll try putting it in fastboot for S&G's. Restart, put it in fastboot and the screen stays on. Beautiful and clear as day, all buttons work, everything reads fine, but, if I go to boot it or do anyother action than "retart bootloader", the cycle continues. T-Mobile, death, hello Moto, nothingness. Now at this point I'm okay with the phone being dead, it's fine, but I'm intrigued now. What would cause the screen to work just fine when in the bootloader and the TMobile splash screen, but die when it boots? The phone is very clearly working in the background. I logged in, used Google assistant, used the flashlight, pressed buttons on the dialer, all without the screen but with haptic feedback and audio. Could the graphical side of the main partition just be corrupt, or maybe the display driver is dead but the main board interacts with it differently during fastboot? I'm far from being knowledgeable on the hardware side of these things but I'm really genuinely interested in getting feedback here from anyone with an idea of what is going on. I'll post a video here in a half an hour or so when I finish up with dinner.

Well... It sounds like there is a short between the screen and the main board. It could have happened when you plugged it into power while parts were still wet causing a short to ground and frying a chip that controls display but not touch on the screen.
Best way I can describe it for you is if an ECU on a car got wet and shorted out. Everything works but you get an engine code for TPS sensor failure due to said short. (The ECU can't read TPS due to a short). That is what seems like what happened.

Well see I would think that as well but the screen does work. Just only in fastboot, and the boot logo.
I got the video here.
Fastboot is a pretty low level and most likely uses basic hardware. I mean really what is there to see but a simple background with some text. Once you load the OS then all the hardware and it's drivers into play. Have you tried booting into safemode? Ultimately you'll probably have to repair or replace, but there could be a slim chance that there's still a little moisture in there and it still has a short somewhere.

Part of Note 10+ Screen Goes Black

This problem just started today, I've done nothing with settings, have not installed any apps recently, did not drop it, expose it to water, or anything that could possibly cause damage. What's happening is that basically about 1 inch-1 inch 1/8 of the bottom of the screen turns black, and at almost random, sometimes it could go a minute and half or so, sometimes 30 seconds, sometimes within 5 or less seconds. The strangest part? The part that goes black still operates fine to touch, so if an icon or letter of the keyboard, or whatever, is located in that area, it can still be selected/operates. Taking a screenshot to try to show it is worthless since it'll show the screen as just fine, so I attached a picture and a video of the problem from an old phone of mine. The blacked out are will go right back to normal if you turn the screen off, wait a second, and turn it back on. Also, if the blacked out area is there, it'll go away after about a half a second when the screen dims right before the screen inactivity turns the screen off. I've only had this phone for a couple months, I got it back on December 7th 2019.
I learned something else. If I manually lower the brightness to a particularly low level, the black goes away, so it seems to in some strange way be related to the phones brightness level (I use auto brightness), this also might explain why the black comes at differing intervals, as my brightness is adjusting constantly to my surroundings, the time before it comes is either shortened or lengthend based on the brightness.
It doesn't seem that strange that the touch still works in that area as the digitiser and the display are two different things. I would factory reset (because Samsung will make you do this anyway) and if still an issue, take it directly to Samsung, that does not look good.

I was just thinking I might have to do factory reset, if that doesn't work, and it needs repair/replacement, do I go to an authorized Samsung repair place (I know I have one within about a couple miles of my house), it's
obviously well within warranty, or take it to At&t store as I do have that AT&T Protect Advantage coverage for my phone?

Did the factory reset, turned out to be a waste of time. That black bar was showing immediately, right at the setup screen. So I guess it's safe to say that it's a hardware issue, defective whatever. Funny story is that when I bought this phone, my att store only had two of them left, one was immediately defective, it wouldnt get past the main logo screen, and now I got this one and it became defective within just a couple months, got to love it.

Just left AT&T store where I initially purchased the phone. They're shipping out a brand new note 10+ to me today and I'll get it tomorrow ?
Glad to hear! That definitely sounded like faulty hardware. Funny you saw two failures, I guess it will happen with such complex devices.
Note 10 plus screen goes black
Hi i thought i was crazy until i saw your thread. The same thing is happening to me but it does not go continuously so id see two red squares first theyre really small and they appear anywhere on the screen then if try to screenshot them they show upblack in the screenshots instead of red . I just need to know if anyone found a solution yet because my phone came with the warranty booklet but it wasnt filled out.

You just need the proof of purchase, or, if you got it on contract, the contract itself will suffice
