[Q] nexus 5 colorful dots all over screen... PLEASE HELP!?!?!? - Nexus 5 Q&A, Help & Troubleshooting

Hello, I am a newbie on this forum.. I have been having issues with my Nexus 5 and was wondering if yall could help me figure out what is going on.
When I turn my Nexus 5 on sometimes the display comes on and sometimes it doesn't. When it does come on, all I get is a screen full of dots. Tiny little dots covering the entire screen. It also doesn't usually go into fastboot mode, but it has twice in what seems like 100 million times trying since this happened. I just replaced the display as it was shattered from a drop, I thought that could be the issue but that didn't help.. So maybe the gpu? I don't know... I'm much more familiar with desktops than phones.. So please help, I'll do anything at this point, even if it takes forever.

Pull it apart again and check all connections.

In order from most likely to least likely, as well as cheapest repair to most expensive:
- Flex cable
- Screen
- Motherboard
A lot of people have had such issue and it's mostly been the flex cable.

Thank you so much, I hadn't even thought about that. I will get back to you after I order a flex cable. hope you're right. thanks again.

Nothing has changed. I got a new flex cable and the exact same thing is happening. What do I do now?

Then its the screen or motherboard. I would just send it in to LG for repair rather than guessing between the two and possibly wasting money.

Screen Problem

Hi,
My phone has a problem, i hope someone can help me, it started about a month ago,
When i slide the keyboard the screen would freeze, the image would freeze or sometimes it would become like this:
http://www.esato.com/board/img.php?id=140762 ( this is not my phone its just a pic i found)
This problem would be solved it i gently slide the keyboard back in, the screen would be back to normal, sometimes i had to slide it out and it
alot of time to make it work.
Well, today i woke up, with the screen of my phone all messed up ( like in the picture), i slide it out and in alot of times but no luck.
I turned my phone off, when i turned it on, the screen doesnt lighted up or showed something, the phone just vibrates, i took off the battery and tried again but no luck.
I read somewhere that i could be the flex cable, so i ordered one, but its gonna take some time to arrive.
Anyone had this problem before that can help me?
I didn't encounter such problems on MT4GS yet. But being a slider phone enthusiast I could 100% say it's a flex cable thing since I encountered that problem more than a dozen times already on other phones(nokia).

I would strongly recommend that you get a cable with the speaker already soldered in place....
+1 to that, get as much pre assembled as possible, this is about the most pain in the butt phone I've ever had the pleasure to disassemble. Read the last few posts here!

thanks for this bit of advice.
Disassembling the front of the phone is a pain. I'm a fan of spending $40 on ebay on a broken phone (where the screen still works just fine) and swapping out the fronts. That will get you a new flex cable as well. Otherwise, you risk having to get a new flex cable *and* a new LCD.
Agreed. First time disassembling front I was scared not to OVERheat phone internals. I ripped in half trackpad ribbon, damaged lcd back cover and got a lot of problems from it.
Then I bought broken phone with good front, but dead LCD. Second time I just lost it, I heated phone so hard that I got burns on my fingers, but it was worth it, LCD glue came off soo nice.
So better to overheat, then underheat when disassembling front LCD.

[Q] Screen drop outs and now always black, why?

Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help
Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you
I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.
Sent from my MyTouch 4G Slide using Tapatalk 2
even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past
Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well
So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(
Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?
There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

Dead Nexus: Color Noise Screen

My nexus was working fine, I received a call, answer it, after the call my nexus screen was unresponsive. After that the screen only shows a colored noise.
I thought it was the screen, but I replaced with a broken glass (working) screen a it have the same symptom. The problem seems to be a hardware one, I hard reset it, disconnect everything, replaced the usb board, but it looks is the main board the problem or (2 bad screens?)
Does anyone have seen this?
I attached a pic of the problem.
I would definitely say its a problem are you on stock are you rooted?

Pretty sure it's the display ribbon port or cable. I've seen this a few times in the last couple of months.

No the ribbon cable from the motherboard to the LCD. Yes it can be replaced.
Either the screen or flex cable. In extremely rare cases it could even be the motherboard.

I suspect a bad ground or something related with the cable. When I touch the cable the screen start working. Ordered the flex cable, let see if it fix it, i let you know.

I've actually seen this happen when a device overheats (I'm looking at you Droid Razr >.>)
Custom Kernels sometimes have this issue as well.
However, if it's constant, a hardware issue is more likely, I'm just giving out a possible idea.

About 5 or so people have had such issue. None were because of custom kernels (and I don't think overheating either). Either a replacement screen or flex cable fixed it for them. Hardware issue, happens.
Thanks to all.
Todays update:
The flex cable arrived today, installed it, assembled the rest of the phone and bingo! Phone is working fine!!!
Happy again with my nexus, i was almost convinced to jump to the g3 but I really love my red nexus.

Nexus 5 Screen issues - Erratic

Hello!
I have a Nexus 5 with no warranty (according to LG, I need a receipt which I don't have) and the display is acting up. I noticed if I slightly bend the phone, the display flickers, sometimes fixes the problem, or it turns off. Over the last 6 months, the touch screen has been erratic and sometimes I have to hard reboot the phone to get it working again. Also on startup, sometimes I get the rainbow coloured "static noise" on the screen and then I push on the screen a bit and it is working again. Does anyone have any ideas what might be the cause and how to fix it? I feel like it's a ribbon cable problem but I have no clue. I went into Bootloader and factory reset it multiple times, pushed the factory image, pushed TWRP and Cataclysm.
Thanks for any and all help!

Replace the flex cable. It's fairly cheap.
If that doesn't solve your problem, then it's a screen or motherboard issue (i'd recommend paying LG for a repair rather than guessing between the two and possibly wasting money).

Thanks for the info. I have been looking for a while but I'm not sure which flex cable to replace? From the iFixIt teardown, it doesn't look like getting to the display cable is easy/possible. Do you have any links for what I should purchase? I'm comfortable with taking it apart and doing the work, just want to make sure I buy the right piece .
Thanks!

Nexus 5 Audio and Black Screen Issues

Hi everyone, I'm have an issue with my Nexus 5 and hoping someone here can tell me whats going on.
It started off with the sound always cutting out, and I have to press the back part near the "S" logo for it to return.
Eventually the screen would go black but I can clearly see a back light is on. Now not only does the sound cut out, and screen goes blank.
It has become very sluggish to reboot it. I hold the power button until the phone reboots "Google" logo appears and the android animation. Now during this time the phone will be so slow to the point of being crippled out and i have to reboot it again and again until it is normal speed returns. Often it will black out during this time.
I'm just trying to understand what is failing. I tried safe-mode and it still has the issue. I cleared cache, reset the phone everything, nothing appears to fix the issue at all.
edit: I forgot to add, when I'm on YT or listening to music or browsing the web, even though the screen is blank with just the back light on, the sound is still going (when it works). I get text/call notifications still during this time.
My Phone Details.
Nexus 5
Android version, 6.0.1 (MOB30Y)
no ROOT
No replies at all, I guess I may have to garbage the phone. Idk what else to do with this device to fix it.
Please don't throw it away.
You said that pushing at a specific spot fixes the problem (or improves the audio situation). This means that it's a hardware problem. I have disassembled it many times and I know the layout. Behind the 'S' of NEXUS is actually the motherboard cover, and under it are 2 connectors; one for the battery and one for an extra 'board' that is located right underneath the LG logo on your back cover. On that 'board' is your screen connector, and also the speaker rests on there, as well as the primary microphone, 3G and 4G antennas and of course the USB port. The connector for this extra board is actually located a bit to the left on the 'S' (when you look at your phone from the back, it's more below the camera).
Now I have to note this: While using my phone, I have experienced some UI hiccups. At random times (very rarely) everything would just freeze for a few minutes, though music would still play. The power button was useless apart from the hard reset, it was so badly stuck. This was a software problem, although it appeared MOST at one point when my motherboard was faulty. Since I got a new device, it happened again but only once. I'm not sure that this is what you are experiencing. If this is the case, then it's a software fault. Never happened on CM so you can give it a try.
But since it's probably a hardware problem, you can always check it out yourself. Obviously if you have warranty you are covered. Otherwise, you can try disassembling it, at least take the back cover and the motherboard cover off, it's ridiculously easy, there is a disassembly guide from ifixit (I think) online, just be careful not to break the clips of the back cover (xp talking). If you open it, keep away metal things and the first thing you do after you remove the motherboard cover is remove the battery (xp talking again). Obviously turn off the phone properly before you attempt anything. Everything is sensitive in there so be careful. What you should look for is the long connector that connects the extra board that is located at the bottom of the phone with the motherboard. That's what you are pushing so if it's not sitting correctly, then that's your problem.
Plus, everything in there, apart from the motherboard, is cheap and can be found on eBay so don't worry if something is broken (unless it's the motherboard, then no hope ).
I hope I helped.
Firstly thanks for the reply. I did manage to remove the back and get to the connector you were saying. I reseated this and noticed the phone was working much better. I noticed the following still.
When it starts acting slow/crippled pressing this connector fixes the issue. However once the screen goes black with just a backlight this method is rendered useless. Also sometimes when I plug in the wire to charge it will cripple and or go black. So I wondering if the board is shot as you suggested to order a new one, or is it the connector strip ?
Again thank you for the response.
It seems like this board is causing everything. First, check the connector on the motherboard. Make sure that nothing is wrong on the motherboard. Then you can remove the bottom black plastic thing that has the speaker on it and 2 antennas. Then, inspect this board. Check the connector of the display. There is only one big connector on it. This board is glued on the frame of the phone. You can remove it but do it carefully. Do it slowly so that you don't break it. First, remove the antennas extension cables from either this board or the motherboard, and then pull it out.
This board is definately responsible for the black screens and audio issues (unless your display is faulty, check its connector), but I'm not sure about the phone being sluggish. Since this board offers input to the motherboard, I suppose that it could be its fault.
Remove it and inspect everything. Then, if you want, you can order a new one. If you come across D820 and D821 models, I don't think that this part of the phone has anything to do with it so don't worry.
I will take a further look into this for sure, and report back. If you can provide which motherboard is required for my device, so I can also read into this and so that I may order it right-away. Is there any model number or something that indicates which board to order once it is open?
Thanks again!

You don't need to change the motherboard, not to mention it's very expensive and hard to find. What you need to replace is probably the flex cable that goes below the battery. For example this.
This is not model specific, you can use it with all available Nexus 5 models (D820/D821, 16/32GB) so it doesn't matter what device you have.
FYI, if you think that you should replace your motherboard (you probably shouldn't), you need to take into account the storage (16/32GB) and the network differences (D820 or D821, the only difference is about the 4G networking, the american version has some bands enabled and some others disabled, and vice versa)
Okay, I just ordered the replacement flex cable. It is going to take about a month before it arrives from HK , I hope it fixes the issues. I will respond to this post once it is here and installed. Thanks again.

in the meantime, pray it isnĀ“t a motherboard issue, the conector can go bad and lose a few solder joints
I have exactly the same problem... I unmounted motherboard and clean everything but didn't help to much... did you find any solution ??
Siamer no solution just waiting for my delivery of the part. However it is getting worse with the blackscreens and crippled lag.

my is the same. sometimes is working for few hours without any problems and than starting again, on the biggining it was power button problem but not I don't even touch that button (I use vol button to turn on) and sometimes screen getting black (with backlight on) and can't do anything so have to reboot... it's so anoying! Hope that parts will fix it, please let me know if you will find some solution. Today I will open phone and clean all connections etc...
Thanks,

I believe the part may fix it. I noticed if i run my finger along the strip the phone may uncripple itself or just turn black all together. I'm hoping it fixes it. I will report asap but this HK shipping is so slow it will be a month. Also there is no tracking
ATM i'am just trying to becareful with it trying not to trigger the issue. I just did an OTA update using FlashFire (6.0.1 (MOB31E) i wish v.7 will be available for my Nexus 5 ha ha!
Also if the Nexus 7p arrives I may just buy it to replace this Nexus5.

Hi Omega59.
Today I bought air compressed can(name: air dust) and open my nexus 5 as much as I could. I clean everything, every connector, every cable etc. and last few hours is working fine... even power button is working ok. I will let you know in next few hours how it will be, hope will be still ok
Good luck!

[edit]
there is still same problem, working better than before, black screen not showing so often but still showing... I think tomorrow I will order oneplus3... Would be nice wait to see new nexus but how... :/
Yeah I'm not sure when the Nexus 7p will arrive, they not even advertised much. I will assume next year?
OnePlus 3 looks nice, but compared to Galaxy 7 it's a bit better slightly. You should check out comparison charts
Maybe they are making a OnePlus 4 soon.
oneplus 3 already ordered. I don't like samsung. I would say nexus "7p" or "pixel xl" will be launch october as always prabaly 4th of october - leaks saing that... next oneplus will be launch around july next year as I know. the only phone that I was thinking about was oneplus, htc10 or new nexus but can't wait to see nexus...
today by excident I broke screen in my nexus 5, got a little bit angry

You probably don't want to hear this, but if it's getting worse, it's probably because of the pressure you apply to it, you make it worse. Be careful when you apply pressure around the motherboard since it's very sensitive. You REALLY don't want to break the motherboard. So if you find yourself pushing on the motherboard too often, you might want to leave it and wait for the replacement part so you won't ruin it.
Waiting for your news...
My part arrived yesterday. I put it in was pretty easy, however the first attempt i had to redo the top connector bc it was still black screen and no audio. After I disconnected the top connector ran some alcohol over it, re-put the top part things are working okay.
Just a note, the little USB connector (charger slot) seems to be very tight compared to the old one. Maybe bc it's new and not as worn down. But even just to put the wire in, requires more of a push, same with removing it.
I will see how it goes before I can really say that was the issue. I will report after a few days about it.

I don't think N7P will be out this year, they have not advertised anything and we are almost in Oct. Right now they are all rumors.

When I changed my screen and housing it was difficult to slide the USB connector in too. Just make sure that everything is in place, there is a rubber think for the microphone, maybe that's what's in the way. Don't stress the connector too much.
