Backlight turns on, unable to display anything - Sony Xperia XZs Questions & Answers

I bought an Xperia XZs from a website called DWI Digital Cameras about a year ago (they've closed down recently due to the new GST regulations). I've had this issue since the day I received it and I thought it wasn't that big of a deal at the time, but it's gotten to a really bad point now.
The issue is that very often when I try to wake up the phone (like almost half the time) the screen does not display anything while the backlight turns on. The backlight might also flash multiple times as if it's trying to get the rest of the screen to wake up. This issue would usually go away for a bit if I either tried to open a camera app from the lockscreen (via double-pressing the power button) or rebooted the phone - the backlight would turn on and off a few times and the rest of the screen would temporarily work again. But now, it seems to be not working no matter what I try.
I'm pretty sure that there's nothing wrong with the screen itself, I even got it replaced once after I accidentally dropped and shattered it and the issue still did not go away. The issue also persists no matter what ROM I have installed as well.
Any experts on this? Cheers.

[Q] Nexus 5 screen showing colorful static

Has anyone come across this before? I was watching a video on MX Player not too long ago, and it seems to have resulted in a permanent colourful static for the phone.
I can't really tell if it's doing anything, but when I go through the motions of resetting it or booting into bootloader, the screen does not change at all.
Interestingly the volume buttons are still working, and if I press the area of the screen where I think the buttons are (e.g., the back/home/programs buttons) I get the right vibrations. Which leads me to believe my screen is broken, and that it's a hardware fault. I'm hoping pretty hard this isn't the case, as my phone is only two months old and it was a replacement for a 6 month old Nexus 4 which had stopped charging.
Anyone come across this before? I'm hoping there's a kind of solution somewhere out there... To make matters worse I bought this phone via a parallel importer AND I'm currently overseas and won't be back till the end of January.
Sigh. Photo of screen is as attached - please forgive the terrible quality as I had to use my laptop webcam.
Thanks in advance, everyone!

Only time I've seen something like this was when my integrated graphics card on my desktop overheated, everything still worked, but colorful static everywhere. I'd let it cool down for a while, chances are it was pretty hot when it did that, and see if high temps might make it happen again.
I just had the same thing happen. Phone had been in my pocket and I had just taken it out to check the time maybe 10 minutes before it happened. The only difference with mine was I bumped into a table and hit the phone in my pocket. It does have a case on it and there is no sign of damage at all such as a cracked screen or anything. The static only lasts for a few seconds and thats right after I force it to reboot. After that it just goes to an all black screen. My LED indicator light is still flashing at me telling me I have an email though so I'm not sure what the deal is.
Were you able to resolve this issue? I too just experienced this issue as well and my phone is currently unusable. Thanks!
Do a full wipe as in wiping the entire phone and making it as if you just got it out of the box. if it persist RMA

Hi, I broke my screen (really bad smash) and had have this static on my new screen. The new screen was apparently fully tested. When using the slim port i can display on my TV and the digitizer works fine, its just this same colour static on the handset. I am now waiting for a replacement USB flex (it was a bit bent in the break) and i expect the new USB flex will fix it. If not then its a bad screen.
Will post the results when i get the parts
Fixed!
Hi,
My new USB flex arrived today. I installed it and found my screen is working perfectly.
The first pic is the same colour static that the op had.. Second one is the USB flex board / ribbon. Ebay for 20 Euro. Please remember that USA users are LG D820 and Europe/rest of works LG D821. I think its important for this part as the aerials connect here ans they are different in USA.
Good luck everyone

Static screen and freezing
Hi All,
Need help here with my 6 month old Nexus 5. It has been pretty good with no issues but since last evening, it started behaving weird. The chronological events are as follows
1. While browsing on Chrome some websites were not scrolling intermittently. This was only in the browser.
2. After about 10 mins of the above behavior the entire phone froze and didn't release itself. I had to force reboot by holding the power button down for about 10 secs. When the screen came on, it was the static screen
3. I again pressed the power button a couple of times but no use. Held it again for 10 secs, then phone rebooted and everything was fine.
4. Continued to use the phone and everything was normal until this afternoon, when the phone again froze while browsing a website
5. Since then the phone screen shows the static and if I press the power button once, the screen switches off and press again the screen comes on with the display showing properly. I can now only perform one touch which is registered and the screen freezes. If I switch off and on again the next screen / action is shown which is the action I did in the previous touch. Every time it registers one touch and I have to switch off and on again to see the next screen. Sometimes the phone just shows static and I have to wait a few seconds (30 sec) before using it again.
6. If I make a call to my phone, I hear one ring and then it is busy tone like I've cancelled the call. However the phone does not show the incoming call.
My phone has been intact and is well protected with screen guards and case. There is no physical misuse / abuse of the phone. I managed to shut down the phone and enter recovery. Here as well it only registered one touch, though the phone was processing and moving the next step. I somehow managed to initiate a factory reset through the settings, but no use.
Now in about 2-3 hrs the phone has become completely useless. I'm uncertain what the problem is, all my touch inputs are registered and processed. The screen just doesn't refresh to the next and requires a power off/on. I picked up this phone in the US and now in India. So I can't RMA the phone and I don't have warranty for this in India.
Any suggestion will be greatly appreciated.

I'm getting the same issue. Tried soft and hard reset. Opened her up and seated all cables. The issue is still persisting. Is replacing the USB flex the way to go?
Hey I have a nexus 5 32GB and the screen started to do weird things and now it isn't working at all. Its the same in recovery mode also do I think that it's not a software problem.
I think there is an issue with the motherboard. Please help me out.
Thanks in advance.

Same thing, Screen now black. Won't turn on...
Hey everyone, I know that this is kind of late to the thread, but I have what I believe is the same problem as everybody else here. I had my Nexus 5 in my pocket for maybe five minutes, and in between the times that I put it in my pocket and took it out again to reply to a text, the screen went all colorful and static on me (Red tint, almost as if I had twilight on, but I didn't). I tapped the back, and the colors went back to normal, but the digitizer wasn't responding to touch. Then, It went black. No color, the speakers weren't working, neither was the backlight on the display. I took it apart, and figured its either the USB flex cable (which looked frayed), or the mainboard. If its the USB flex cable, then I know I can repair it. If it's the mainboard... well, as a sixteen year-old who has no current source of income, I'm out of a $400 phone.
Pictures attatched. Thanks!

I took the phone the LG service center and the technician seemed to know this issue and immediately said that the USB flex cable needs to be changed. The entire fix took about 5 mins and the phone is working fine since then.
Sorry for the delayed response.
I hate to necro up this thread but I'm having similar problems to the op with my nexus 5. About two weeks ago I saw my screen get grainy just like the op and many others mentioned and then the screen went completely black. The screen still "turns on" but it's just black with the backlight on. I can hear notifications and other things and I'm hoping that all I need to replace is just the flex cable. If it's a problem with the logic board then I'm screwed basically.
Anyway that's my story. Bought the flex cable and it'll be here by tuesday so I'll find out then if I'm lucky or not. Fingers crossed.

Hey man, did you ever try this out and get it to work? I have the same problem and was thinking of trying this out but wanted confirmation first.
Thanks!
Just wanted to post here to say that this thread just saved me a lot of money!
Had the same issue (static showing on the screen). Local phone repair shop told me it needed a new screen, without even looking at it(!), and it would be £120 + labour. Told them I would think about it, and came home and did some more research, found this thread. Ordered a replacement USB flex cable from eBay, and fit it by following a YouTube tutorial, and now the phone is back working fine. brilliant!
Thanks xda!
I had a problem where my screen looked like an old CRT TV with particles flashing all over on anything with a static dark background. Any ideas

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

Nexus 5 really weird screen problem

Hi,
I have this really weird stuff going on with my Nexus 5 screen. I cracked it a couple months ago and bought a legit replacement screen for it and installed it myself (glass, lcd and frame). I fixed it with good instructions and it worked properly for two months. However though, now when I take it out of a pocket and try to turn screen on, sometimes it just doesn't light up. It's still on and every button works but the screen doesn't turn on. I have to give it a light tap or two on the back in order to make it light up again. Same thing happens sometimes when I'm using the phone normally, the screen just goes black and goes on after tapping it couple of times. Otherwise the phone works normally like it did when I bought it two years ago and after running couple of tests with screen, everything seems to work from touch interface to the graphics card.
Tried looking it up, no results.
I've noticed that the front camera doesn't work for some reason (probably just broken) and the battery lasts in use only 2-4 hours which isn't that much of an issue since I'm looking for a new phone. I just want this one to last long enough till I buy a new one.
It comes up when tapping the screen or power button? It could be a power button issue.
The screen comes back on when tapping the screen or the back of the phone. The power button isn't the issue. The screen just goes black but nothing else happens. It doesn't turn off or go to sleep mode.
Strange issue. I've never experienced it and any problems I had were related to the power button.
Could it be a loose connection inside the phone? Maybe an issue related to the proximity sensor?
Thats actually what I've thought. I have checked the phone's insides twice and didn't see loose connections, and the problem feels like it's related to proximity sensor since the screen going black happens exactly same way that when calling someone or doing something else where proximity sensor shuts the screen. It's really weird though...
Huh, I took backplate off and unscrewed the motherboard cover and took everything apart and rebuilt it and now the problem is gone. Seems like there was just some bad connection somewhere.
Glad you got it to work without having to pay someone to fix it

Nexus 5 Screen goes black after some time but some functions still work.

Hello all! Some time ago my nexus 5 started to have some issues with the microphone and a couple of days after it stopped working. I searched how people generally fix it because I have no warranty and I didn't want to spend much money giving someone to fix it or even get another phone. So what I did was I open the motherboard plastic protection and put a tape (a bit thick) right below the camera (above the battery) to make some pressure on the mic connection. I closed it, closed the phone, turned it on and the mic was working again. So far so good.
Then I noticed that out of nowhere the screen went black and if I pressed the power button it would give only black light. After some research again I noticed that it wasn't the LCD problem because if I rebooted the phone (power button + volume down) it would work perfectly, but after some time it'd go black again. Sometimes it even makes weird colors, grey orange and some lines (like broken screen) and then goes full black.
I already factory reseted the phone but the poblem still persists. I wonder if it has something to do with the battery (maybe should get a new one) or with some hardware connections. What makes me think that isn't a hardware problem is because it always works during some time when I reboot it. But ofc im not 100% sure because it looks like this happened a little while after the mic fix.
I saw someone talking about memory cache wipe could fix this. I did try this recently but I don't think this could be the problem and this is why: Some moments ago I tried to reboot it to make the screen work again but this time the reboot didn't work. It started to give those weird colors and lines. So I connected it to the charger, waited a bit, tried to reboot again and it worked. The screen is now temporarely on and working what makes me think even more that it could be battery's fault.
I hope I explained everything well if you have any doubt please do ask. I'm just trying to know exactly what the problem is so I don't waste time and money fixing actually non problematic parts.
Thank you.
PS: Before I got the phone like 2 months ago, it was used for almost a year by a family member.

Nexus 5 Black Screen Issue

Hey, I m facing problem of nexus 5 black screen issue it turns on but nothing shows on display...(display tested works,and flex cable also replaced)
Can anyone help in this??
There is no display in fastboot mode either?
If you are sure the display connecting cables work, sounds like a motherboard problem.
I'm not trying to hijack the thread, but I thought it would be easier to post in here since I seem to be having a similar issue. I can't figure out if it is software-related or hardware-related.
I recently updated my Nexus 5 to Lineage OS 14.1 (11/7/17) and my screen began glitching. After an indeterminate length of time, my screen starts bugging out - the touchscreen won't register any touches, pixels get glitched and then it usually goes black. Sometimes the display will reset itself, and other times it will stay just black. Now the odd thing is if I force a reset by holding the power button down, I can get it to reboot and usually it fixes the issue... briefly. I've noticed sometimes however that even the boot animations will glitch out too, but by the time it gets to my home screen it's just fine, again for an indeterminate amount of time
The phone was bought used from Swappa probably almost a year ago now. Worked great up until now, I'm sure it's been dropped before both by me and the previous owner, but the screen itself from the outside doesn't show any signs of damage (No cracks, scratches).
I've since gone back to an early October build of LOS14.1 that wasn't giving me any issues like this, but I'm still getting them. So I'm leaning towards it being a very odd hardware issue or maybe I need to Factory Reset and dirty flashing updates is catching up to me.
