Nexus 5 really weird screen problem - Nexus 5 Q&A, Help & Troubleshooting

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

[Q] Touch Screen working but backlight is really dark.

So, a few days ago i received my xperia arc s housing in the mail from ebay, So the next thing i do is replace the housing and put it back together, Its all working but i notice the back button not working, open the phone up again and mess around a bit while the battery was still in the phone, but then the screen stopped working, and i just put it back together cause i couldn't do anything about it. The touch screen works but it doesn't not display anything, i can start up the phone and unlock the screen and feel the vibrations but the display is really dim, like if i take a flashlight and put it over the screen, i can see everything but when i take the flashlight away i cant see anything, The LEDs near in the home buttons are not working either. What some one did suggest is that the chip that controls the LED's are at fault and damaged. Any other suggestions would be highly appreciated.
Thank You

Problem with the backlight

Hi! Two days ago, my phone dropped in water , i put them immediately in rice until today. When start it with the power button, i felt the vibration and i hear the open sound. But the screen remains black... but i discover that it was just the backlight because when i watch the screen under a lamp i can see the interface and slide between pages... but its very dark. Is it possible to change this backlight? or just wait few other days to allow time to dry fully. I welcome your suggestions! thanks

When there's water involved, IT's hard to know exactly what damaged. Could be just stain on the ribbon connectors, a burned fuse/diode/resistor (all of them micro sized) etc.. or just the LCD's backlight damaged entirely.
Keep it on rice for more time. I would make the battery to discharge to 0%, But it's also more recommended to keep the phone OFF. Only my friend LUCK knows.
To change the backlight, the whole screen needs to be changed.
Backlight died on me. Possible moisture.
First, it was on boot loop (on stock rom)
i went to restart it (holding power button and volume down)
then the screen turned bright white, restarted it and then the backlight died, dismantled the phone, now still in rice, also happened on 2nd April.
Any help is greatly appreciated.

Took it apart down to the Screen (not the screen layers), left it in rice, works like a brand new now. Cheers.
I just replace all the frame and lcd for a new on my nexus 5, but the problem was still there... no backlight, i can see a little bit the screen, but it's very dark... do you have any idea for try to repair this, because now i don't think that it's the screen but more a motherboard or power problem for the backlight :S
exactly same problem here
nexus 5 phone dropped in water.
Backlight went out permanently - rice didn´t help.
Can see the display working using a flashlight - so rest of the phone seems to be working ok.
Just pruchased a new screen, put it all in and still the same problem: display works, touch works, backlight is off.
So it seems the backlight part of the display receives no power - anybody has an idea how to fix that?
thanks
I have answer to this!
I have had this problem like 3 months now and i finally fixed it.
Basically what i did was that i bought a broken nexus 5 (only the screen glass was broken) and tried to swap every part one by one. The one that was not working was the main dock!
It is a cheap fix, like 10£ on Ebay.
I am writing this post because anyone else haven't.
I hope that someone sees this.
I now copy this message to all other threads so people can fix their nexus 5's
PS:as you can probably tell English isn't my first language.
Hello! I am having the same problem. The cell phone fell to the floor and the next day the problem began. The display is not broken.
What are you taking about when you say "main dock"? Motherboard aka mainboard?
Thanks!

Xperia Z3 screen flickering, help

I gave my Z3 a little bath in tap water in the sink. It was not submerged so this is more like a shower. I double checked and secure the ports. I don't even use the ports anyway because I have magnetic charging. I dried it and started using it. It was all fine until 5 mins later it just randomly turned off. Battery was good, tried using the power button and it wouldn't work. So I did the power button and volume + method and it fixed it. But the touch screen didn't work sometimes (randomly), there was a blinking red light before I booted it on, and there is rattling near the camera area when i shake it. I ran diagnostics and noticed that my screen was also flickering. Some of the tests used vibration as feedback and this made the flickering worse. Now the screen is struggling to stay lit. It turns on for 3 seconds and then it dies. You can only see parts of it too. I need help. This phone is unusable. I bought this phone (Sony Xperia Z3 D6603 black) from Worldwide Distributors on Amazon.com 3 months ago. I only took it into the water a few times. I don't think its water damage because I had the flaps secured unless Sony gave me a defective phone. I paid $700 for this and I'm not rich either. I was saving up. The phone has the standard 2 year warranty. Somebody please help. what should I do? Will Sony fix it or give me a new one?
UPDATE: Screen is dead. It still turns on and touch screen still works but cant see anything. It's like it lost signal . Kinda like how a tv loses signal. The tv still works but are no shows on.
IMPORTANT: I just found a little hole that shows part of the screen backlight. Its on the side but its more like a crack. I haven't drop this or anything. So this is possibly how the water got in. This is also Sony's fault. Will I get a new replacement or refund or repair or something?
Thanks for all your help.

Happened to me too! The screen is black but is showing the brightness and the touch works. It's totally weird!. i'm going to send the phone to SAT
Seems the lcd backlight is still working where the lcd screen is not;
not sure whether the warranty covers water damage or not...
Got around the same problem. happend in the water screen went black phone was still working. After a lot of reboots and resets it started to work for around 3 seconds then evantually the screen was staying, but is flashing now, looks like the flickering happens when the screen gets too much power. In light conditions it either flickers or is real dark.
What can I do to fix this? Or do I just contact Sony? I've also tried the pressure test and it is water resistant so it has to be something different.
If the screen is cracked they will charge you for the replacement for sure

Hi. I've noticed that my screen flickers when I put the brightness on maximum. Watching the behavior it makes me think that it happens all the time, but it's only noticeable the screen brightness is high. Tried to get it on film, but my camera does not seem to pick up the flickering.
I noticed this after a pool bath with my phone, but i don't know if it is related to that. I did not a chance to use maximum brightness before
I do not have any other issues though, just the flickering. Should i send it to repair? My phone is an 6633 Dual Sim Z3 (Brazilian, unbranded) with less then 3 months of usage.

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.

Backlight turns on, unable to display anything

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.
