[Q] Black screen even after complete wipe - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hey guys,
so I bought this Z1C on ebay the other day. In the description it said "phone turned itself off because of low battery, charged it, turned it on and screen suddenly stayed black yadda yadda yadda". So I googled it and found it to be just a simple matter of black screen of death. I was excited because this was a pretty neat deal.
I tried holding Volume Up + Power, it vibrated three times and turned itself off. I waited for around 20 seconds, turned it back on but the screen stayed black. I was surprised to say the least. So then I downloaded a Stock ROM (D5503_14.4.A.0.108_GenericDE_(1279-6978)) and flashed it. Flash was successful but the screen stayed black. When I connect it to my Laptop Windows recognises it without problems and PC Companion does so too. It even asked me if I want to update to .270. when connected. So I did that in hope of that maybe this will fix the problem. But it didn't. The update went well, everything worked fine except for the screen. I even tried to flash just the kernel. That didn't help either.
Could it be that this a hardware issue like the screen lost connection to the power source or something? Because I noticed a scratch on the upper right corner on the aluminum band. Can it be that the screen somehow got disconnected from power when it hit the ground? Or is it a software issue and tere are other methods to deal with a black screen?
Any help will be greatly appreciated!!!
I also noticed that the device disconnects on its own after some time when connected to laptop and PC Companion. After that I cannot reconnect without force shutting it down and turning it back on.

[Q] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!
Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!
Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?
Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it
The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!

LG3 wont boot + Blue screen

Hello, i faced a serious problem this evening, just after i finished a call phone, the screen of the phone went Blue and then it went off, i started to put it on again and then it showed the screen with LG and then it went black no boot at all. i removed the battery and i tried again and still the same, so i tried to remove the battery and put it again and plug it with the computer, it went on with charging battery and then suddenly went to blue screen again.
So i tried to put the recovery mode with power down and on/off and it worked i got the recovery mode screen with factory reset but it was only with factory reset, i tried it and then i put yes and it reboot and then after LG screen, it went black again....
so i tried to put download mode with usb cable but it wont, always i got the blue screen. what should i do, where is the problem exactly for people who had the same problem ? the batterye ? the motherboard ?
anyone to help ? i changed the battery and it wasnt coming from it, and the phone showed others anormalies like sometimes u can charge the battery and you see the % and sometimes it goes blue screen and shut down. anyone had the same issue before ?
My LG G3 randomly started giving this problem for 3-4 days till it went completely bad. It just wouldn't get past the Blue Screen. Since I had to take a backup before taking any further action, I have been able to get it up and running for very short durations by keeping the cell phone in the freezer for an hour or so. Yes. I am not kidding. After it freezes, I can get it up on about 5th or 6th attempt. Sometimes even more. Be mindful that the battery is now showing a red humidity marker due to the freezer.
I am thinking of asking LG to repair it. What a piece of crap. Its only 18 months old for me.

LG G3 unresponsive/extremely slow

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).

Did my SPH-D710 brick itself? Won't power on; steady blue LED

Not sure if there's anyone left who browses this forum, but I guess it never hurts to try. If there's a better place to post this nowadays, please let me know!
I have been using my Samsung Galaxy S II Epic 4G Touch for about 9 years now. I never messed around with rooting or installing any custom stuff.
I don't remember what version of Android it was using; I'd assume it was whatever the latest official version was.
Last night, I was reading an ebook on my phone; nothing out of the ordinary. Phone seemed fine. Battery was at about 75% or so.
And then, for no discernible reason, the phone froze and became unresponsive. I tried rebooting, and when I did, a screen came up asking for a "PIN or password to access the encrypted device memory" or something like that.
I had never seen anything like that screen before.
I tried restarting again, but this time, the phone just straight up would not power on. The device's status/power light was a steady blue, not blinking.
If I held down the power button for about 5 seconds, the light would briefly turn off and then go right back to the steady blue. The phone's screen remained blank.
I tried using a different battery, but it made no difference. The phone simply wouldn't boot at all and would not give any indication that it was accepting a charge. I tried holding down the volume buttons and home button in addition to the power button, but it made no difference. Couldn't even get the Samsung splash screen.
I tried connecting it to the USB port of my laptop and desktop PC. Neither device could detect the phone.
So, I'm left wondering, did my phone just suddenly "brick" itself or experience a sudden hardware failure? Is there anything I can do to salvage my phone?
Thanks.
