Black screen after replacing the phone screen - LeEco Le Max 2 Questions & Answers

Hi guys, I have a really big problem. While changing my le max 2 screen I accidentally turned on the phone without the screen connected, now it keeps vibrating every tot seconds like it is cpntinuously restarting. I tried connecting the screen and only the backlight turn on and the screen is black, not even the touch buttons, and he keeps "restarting". I'm 99% sure that the screen is not damaged and that I have not damaged the phone. Someone have some ideas on how could I fix this? Pls help me find a way to solve this cause I have no money for a new phone :/ Thank you

I tried but it has not worked I tried a lot of combination between screen, battery, wall charger and pc but for the moment nothing worked. Tomorrow I'll try the unbrick procedure just to add it to the list :/

After the unbrick procedure my touch buttons turned on for a sec, then turned off again. They turn on randomly :/ Screen is still black and now when I connect the phone to the pc I see it as "Qualcomm HS-USB Diagnostics 9025". Dunno what to try more

im wondering if you were able to fix it, i have the same problem after replacing my screen

same problem. is there improvement?

Any new here?
Yesterday I replaced my fingerprint sensor, but after putting the screen got the exact problem that the OP guy says, the screen is black, just turn on the back side, sometimes the buttons and so on.
Some one could solve it?

Me too , Anyone can help us please. ,

times ago, i had the same issue on a nexus 5 (hammerhead) after screen replacing. i've solved buying another device and putting the n5 in trash.

For what I know the screen connector on motherboard is extremely delicate.
Maybe you guys have broken it.

[Q] Xperia X10 won't turn on.

Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks
Try to format phone with this method hope it should work as it seems the issue is with OS only ..

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:
http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiax10?cc=gb&lc=en
That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.
If all else fails you could try to flash back to your original fw with the tools here:

That won't do anything.
I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

Indeed. It could be a frozen chip, memory fault, power-regulator and so on.

Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.

Strange problem with my i535 (vibrate pulsing)

so to begin with as much info as possible, this began yesterday when I noticed my power button was unresponsive. I tried issuing it to turn the screen off and turn back on, but nothing. So I held it down and eventually was able to force restart it believing the device was just being unresponsive. The next thing I knew, it wasn't turning on and it was simply "beating." By beating I mean the phone is off, whenever the battery is in, it just stays on a blank screen, it might load the samsung logo, but ultimately it is a blank screen. Something extremely strange is that though the phone is off and unresponsive the damn thing is pulsating. As if it had a heart beat lol, but it just vibrates every 3 seconds. Has anyone seen or heard of this? My research and found that the typical problem is a faulty power switch which is what I'm being led to. I found suggestions, none work. There is one I have yet to try. It is this one, /watch?v=3Glllc7bEJs this is quite an extreme solution that I dont mind going to since I am due for an upgrade any how. I just want to remove a lot of important information that is on this phone before I upgrade. Any input would be greatly appreciated.
TL;DR
Phone wont turn on, blank black screen with phone vibating every 3 seconds. Potentially power switch, Need help recovering data.
Thanks!
EDIT: The problem is called a "boot-loop"

[Q] galaxy S3 dark scrren

My galaxy S3 is showing a very weird problem. I was using the phone and before reaching home the battery when completely flat. When I arrived home and plugged the phone to the wall charger the screen remains dark, black. Now the battery is full charged (green light) but the screen remains to the same estate. When someone calls me the phone rings. When I plug it to the computer I can see the files inside the different drives. I reinstalled the OS that is 4.3 but still same problem. I didn't drop the phone and It didn't have any shock.
That is weird. I am thinking of a dead screen but before going for a chirgucal operation on my beloved phone I wanted to ask if that couldn't be a software problem.
Happy to hear from your experiences.
Boot into download mode, volume down + home then power button. If the screen is dead in download then it is hardware.

never heard this type of problem
try to go into recovery and check if it displays anything
If successful do factory reset
In download mode i can see nothing. That is really weird. I am letting the battery drain completely and i will check. Thank you for your replies
I wanted to upgrade so far what i am getting. The screen while dark, black is reacting to touch actions: for exemple when i lock the phone with the power button i can hear the lock sound;when i unlock with the lide action on the screen, I can hear the unlocking sound. I think that must be a weird system problem. If the screen was broken will it react to such touch actions?
Lide=slide. I can actually take a call with the slide action on the screen. When someone calls me i just have to slide my finder at the proper place on the screen to take the call. I need help please.
Most probably its the hardware. Your LED seems to be ditching you. And yes a bad led can still response to touch despite of being black all the way. Actually it's the digitizer that responds to the touch NOT the LED itself.
In your cas3 so far from your feedback I can say that you are having a bad LED everything else including the digitizer is working well.

Thank you i w
ill try it check it tomorrow. I will try to install another firmware, may be 4.0.4. The one i was using i just installed it 2 days ago.

Can only get to a Sony logo flicker when plugged in, dead when not

Hey guys,
Went to use my phone yesterday, never flashed or anything like that, and it just wouldn't respond. When I plug it in the sony logo flickers every 7 seconds and it won't respond to any button combination for rebooting. When it's not plugged in I can't get any sort of response.
Please tell me someone has encountered this before.
Same problem
Hi I have the same problem. Only is that the screen flickers every 0.5 seconds with SE logo.
I downloaded the repair tool but not abLe to process the repair on my phone. Nothing works. Opened the phone, removed the battery plug, tried to power on the phone without the battery plugged-in, nothing. Please help.
Sony repair wont help me. Apparently there is calcium on the magnetic ports or liquid damage in the phone; no liquid damage at all, phone was never put in water and nor any of the white stickers turned red.

Maybe due to corrupt software. Try flashing a new firmware using flashtool.
Hey guys, got some update from a repair center I usually deal with. It seems that the motherboard is dead. According to them, it seems that the battery might have been overheating and might have affect the motherboard. I'm going to try to call the sony mobile tech support and see if a repair mailer could be sent to me and going to keep you posted.
Cheers,
