[Q] Sony X1 keeps rebooting - General Questions and Answers

Hello everyone.
Recently my Sony X1 has been restarting everytime right after it hits the windows green screen. Unfortunately I had figured this out a little too late, and my battery wasn't able to charge up again for a while. But searching these forums I found a solution to that, which was to charge the phone without the battery, then place it in afterwards.
My phone starts up again but the same problem still occurs. My phone keeps rebooting it self right after it hits the window screen. The only other thing I have observed is sometimes when I turn on my phone for a split second my screen emits small black and white squares that are distorted.
Any suggestions would be appreciated if there is a way to solve this.
Thanks.

CECT w800 wont boot

Hello, i've been searching around, and cant find anyone with the same problem, so i'll go ahead and make a new post.
Today i got my new phone, and i have a problem turning on the phone after just 40-50min use.
My problem is that every time i try to boot the phone, the screen just lights up really bright white, and then shuts down (this happens no matter what battery i use, it came with 2)
The same white screen appears when i connect the poweradapter. While its running from the poweradapter (not running, just making a fan-sound, tho i doubt its any fans in there) it doesnt react if i press the power button, so i am suspecting the batterie(s)' are the problem.
Thanks for any help

Need help identifing reason for strange and frequent freezes

Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks

[Q] Nexus 5 display corrupts after boot

My Nexus has a display problem and i'm trying to troubleshoot what the issue is and I'm wondering if anyone could help as it's not obvious where the issue lies.
What happened is I was using it as normal this morning and then the screen started flickering to different sizes/colours until it finally just went off. It was almost like it is trying to find the correct refresh rate and the colours appeared polarised at one point. After holding power down to reset it, the google logo appeared and then the spinning dots. Once the boot was complete the android logo appeared and then as soon as the main screen was displayed the display cuts off with a white pixelated mist and shuts off. The phone is still running as if I connect via HDMI I can see everything as normal however the phone responds extremely slowly. I can get into recovery however the screen quickly does some strange things, it flips like a mirror and cuts 1/3 of the screen off.
I'm not sure if this is a LCD problem as its a replacement from ebay that I've been using for a few weeks now. I would suspect that before anything else however it's odd the pre boot logos display fine. I've checked and cleaned all connections however it's still doing it. I'm running stock 5.1.1 rooted.

Unresponsive black screen after booting

[F8332/Locked BL/Official] Screen goes black and doesn't turn on when booting. Tried software repair with Xperia Companion but still the same problem. Phone is working even with black screen because it can still receive calls but no display so you can't answer calls. Tried restarting/power off. After the sony logo and xperia it goes black when android os starts. Tried searching this forum for same condition and I think there is none so I posted this concern of mine. Please help.
Hold UP, and Power button for 30 sec. It turn on on settings it will work on.
Hi there.
I know this is an old post but did you ever find the solution for this? I have a xperia xz1 with the same problem. Display goes black right after sony and xperia logo when android OS starts.
Thanks.
Hello guy, I also received a phone with this same issue, screen goes off/blank after successful boot up, but the phone is still working, just that you can interact with the screen.
After several attempts, (replaced screen, battery. Yet nothing).
So, I pressed the corners of the phone and it came on ( not immediately though).
Then I saw a notification about cover settings.
To cut the story short. This is the cause of the black screen and solution.
Go to settings > Display > Cover Settings> turn off.

Backlight on, no image

Hi guys,
I am experiencing the wierdest thing on my brother's Xperia Z3.
2 days ago, the phone randomly stopped showing images on the screen, but the backlight would still switch on and off as normal when pressing the power button. If the phone is restarted in this state by using key combos, the Sony logo won't even show up. This problem started intermittently, but now it does this for a much longer period. The issue would usually occur after the phone being locked, or if it were being used, the screen would show horrible distortion on the bottom half and become non-responsive until the screen switched off and any attempt to switch it on would be make the phone behave as described earlier.
I used to be able to make the image work by plugging in the USB cable, but this method seems to have stopped working, or at the very least has a really low success rate. I have tried all the soft reset methods: Power+VolUp, yellow button in the sim tray, none of those work for me.
I have just stopped short of reflashing the phone with Flash Tools.
Has anyone had this problem before? It is really confusing me as to whether this is a software or hardware issue.
Any suggestions?
I reflashed the phone using Flash Tools and the phone is still behaving the same way; just the backlight is turning on. Besides that, the phone seems to be making the correct noises and responding to the USB cable. Anyone have any ideas? Could it be the screen itself? I'm worried that it may be the motherboard.
Ok, I found something that works. If I hit the device with my hand on the back or the screen a few times, it seems to bring the phone back. My suspicion is either a loose screen connector or something on the motherboard. I'm not really comfortable with opening the phone up, so this is going to be my go-to solution. Hope this is able to help someone.
