[Q] Jeeeeiiii black screen problem, any ideas what to try?

Hi,
I only got to use my sensation a guess for about 2 or 3 months, then I rooted it and everyone was really happy exspecially me . Had it like that for about 10 days, went out for a few drinks, wich turn out to be a lot of drinks. Some how I decided to take a sprint down the street on speed that peoble still talk about. But when I took my phone from my pocket the screen was all colourful and perky. I could answear but not see anything.
Took the phone apart and found out if I fumble around the flex screen cable it work, but it worked for a while and then it malfunction again. So I decided that it was the flex cable on the screen. Bought another screen from ebay, and when I was changing it, even though I was very very careful and doing everything in slow motion the flex cable on the digitazer ripped in two peices so I went again to ebay.
Got one and put it in. But I only get black screen, when I press on the screen lights up and off, and then it vibrates. The phone can connect to the pc but when I jus ddms to take a screen capture it captures a big black image.
So it might be a hardware failure but I´m a very stubburn man, so any ideas on what to do or what to try, before I will get bold?

If your phone can connect to PC , then try adb . Hope you the basics of adb.
Open an adb terminal. and type : "adb reboot recovery"
Your phone should boot into recovery. Then clear cache and dalvik cache.
Now reboot your phone.
If this does not help, then remove the sdcard and try to boot.
By the way, Are you S-OFF and rooted??

not working
It is like he has no firmware installed.
I can access him through ddms in the adb tools folder, and see all the process
that he is doing when he is in debug mode volume down plus power button pressed. But the screenshots are black.
But I can´t access him when he normal boots up?
I rooted him, with I think ICS, dont know if I did s-off or not or if it
worked.
Can I flash him with someting through adb ?

[Q] Need help with blank screen after replacement

Hi all. I'm having an issue with a 727R. I replaced a broken screen and now can't get the screen to stay on. Its a non rooted, factory 2.3.5 phone. When I turn it on, the sghi-727r screen pops up for several seconds and then dissappears, phone vibrates once, notification sounds appear shortly and all touch functions appear to work (by sound and haptic feedback). For all intents and purposes, this phone is on and working perfectly...if you're blind lol. I know the replacement screen works because it works perfectly if I go into download (odin) mode. I've been searching threads and haven't been able to come up with a solution, as most of the other blank screens are from bad flashes. Keep in mind that I am also testing this with the casing removed as it is a repair for a friend (if that makes any difference). Any help or ideas would be greatly appreciated and thanks in advance.

Is the brightness maybe turned ALL the way down? When it finishes booting shine a flashlite on the screen and tell me if u can see text, icons etc...

I'll do that as soon as I get home this afternoon. I could only hope that's all it is, but i'm a little skeptical that I could be so lucky. forgot to mention that I have also odin flashed the stock rom back on just in case of software corruption. I would also think that I would get full boot logo's during the boot sequence, but hey!....its definately worth a shot! I've seen stranger things . Thanks for the quick response.

No worries, keep us informed. I didn't even bother to ask because I just assumed someone at your level who can change a screen would intuitively know to Odin stock... I was right :good:

So you had display for start of boot and d/l mode? If so, then I'll go no farther until I get another replacement screen.:crying:. Come to think of it, when plugged in and off, the charge symbol shows up for a second and its discoloured (almost like its made of vertical lines that are pinks and grays). You may have just saved me a lot of time. I was leaning toward trying to adb error logs in hopes of finding something. Other than that it was going to be a reflow on the gpu since the phone did do a leap of faith from 6 ft up....and lost lol.

No dice icenight. Tried out of hope but its completely black. I was really hoping for maybe a fault that could be fixed with a flash.....whoa is me....looks like I may be sending screen back and getting another. I cant send it out for another day so if anyone has any other ideas, or wishes to guinea pig this unit until one comes in, feel free to chime in. And thanks for the responses so far!

And the winner is....Crashpsycho! After months of trying to find a replacement, i finally got my hands on two of them for a decent price. Popped one in, odin'd jb stock and voila! perfect phone again. Thanks Crash!

[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

Froze and then won't boot. Is it dead? :(

Hey guys.
I was browsing the web using Chrome on my Galaxy S6, until it suddenly completely froze, a few seconds later white LED went on while the display was on on the frozen, halfway loaded Chrome page. I did soft reset (volume down + power button), the screen went black with only the white LED being on. Upon retrying sometimes it would display the Samsung logo (static, not animating and not progressing) and would be stuck there. I allowed the battery to die, plugged it in and I had a fully functional charging animation. After it reached 20% I tried to turn it on but now nothing is happening at all - just black screen, LED is off no matter what. I tried power + volume up + menu and nothing is happening, just black screen. Charging does nothing now, and when I plug it into my PC the PC does nothing (as if nothing was connected, not even unknown device).
Is there anything at all that I can do? What could this be?
Additional info:
It's the international version, running it's official software, I never tinkered with it in any way. I have no idea what is the bootloader status but it was not altered from factory (it came from Orange Europe).
I replaced the battery last year at an official Samsung service center and never had any prior problems.
I would really appreciate your help, guys, as I have no idea whether the phone's time has come and there's nothing I can do (and should go and purchase an S7 or something), or if there's anything that I can still try, or maybe it's some trivial problem?

Try disconnection and re connecting the battery. It may be a hard job but that's the only thing I can think off. If that doesn't you may have to replace the logic board

Thank you. Since I'm not savvy enough in regards to opening it up and re-sealing (and don't have any of the necessary tools), I guess I'd have to do that at a service centre, and considering it might not even fix a thing, do you think it's worth risking and spending money on? My alternative is getting a used S7 for $220, and any cash I pour into fixing this one could go into the other phone instead.

Nope, get the S7. Samsung quoted way too much to fix my S6 as it needed a new logic board. They said it you may as well buy a new phone

Even if you wanted to repair the s6 it would be too much work and you could risk breaking something else. I saw a guide on YouTube and you have to remove the screen assembly to get to the logic board. Older galaxy devices aren't like that and are much easier to repair

Mi Mix 3 Bootloop after screen replacement

Hi, I'm new to the forum and to mobile operating system troubleshooting in general. I'm hoping to gain some insight into an issue I'm having.
I broke the screen on my mi mix 3 and after waiting for 2 months it finally arrived from Shenzhen. Yesterday I disassembled the phone, connected the new screen, turned it on, and it just went into a bootloop. I've never changed any part of the operating system on the phone before so I just assumed something was making a poor connection. I unplugged all the leads and plugged them back in again, checked that everything was firmly in place, and ended with the same result.
Fastboot will run sometimes for 10+ minutes and then the phone will just shut off, normal booting it will switch from "Mi" to "MIX" and the animation at the bottom of the screen will freeze after a couple clicks and it will loop back to restarting (but twice it has just ended with an all white screen). Rebooting from Mi Recovery mode results in the same.
From what I've seen I'll just need to follow this and flash the phone : https ://c.mi .com/thread-2504118-1-1.html?t=1590725045909
But my question, is there any possible way to try to fix this issue without loosing all my data and without using a back door method that may just brick the phone?
Thanks for any help, btw I still have the back glass off (I've tried with the fingerprint scanner plugged in, nothing) just in case it could somehow be a hardware issue.

So I've given up on trying to save my data, I don't really care much about that to be honest. I just really like this phone and would like to use it. I tried to flash the phone using Miui's official instructions but I can't unlock the bootloader because I can't download the app Miui's flash tool is requiring me to download on the phone to authorize it.
I guess I'll keep looking for a work around.

I changed my display too and it's bootlooping. Did you solve this problem?

I changed my Display too...everything worked fine when I tested it. I unplugged it again to clean the phone and to bring on the glue..when I had the Screen on I restarted and had a black screen...so tried to remove the screen which then just broke...so I ordered a new one and a new display flex cable - I didn't glue the screen yet because I either experience black screens when the screen gets pushed against the backplate or the phone ends in a bootloop -> for the bootloop thingy I just waited for about 10 minutes and then it started normally so there must be something with replacement screens...I don't know whats going on -.-

Hi
Has anyone managed to get this fixed?
The screen works initially but after a while it goes blank, reboot I get the Mix logo not mix 5G. The replacement is a LCD.
Looks like it is stuck in bootloop as inserting sim does phone does not ring when I call it nor front face camera clunk when I slide it
