Hi
I have Mate 7 MT7-L10.
I smashed the screen and bought replacement screen from ebay.
After replacement phone started OK for 2min. After that no display.
I took of lcd connection and reconnect but no luck.
Then tried battery connection and reconnect after few seconds.
It started for a while then turned off again.
So need to do the battery and LCD connection again to get the display.
If I don't flip the phone it stays on display.
As soon as I flip over to put all screw and put the back cover display goes off. Then I need to reconnect everything.
I got display more more than 30 min while just left stable.
Any idea how to fix this.
Thanks
I have the same problem, but in my case the screen displays a set of white footprints, the date and time. It won't let me get past that after. I know it's not the digitizer since I can boot into recovery twrp and make selections, but booting the system brings me back to the display of the footprint in the center screen. No idea why it's like that...only after I replaced my broken lcd it gives me this problem.

I recently got a touch pro of a friend with a damaged screen that didn't turn on but the touch screen was responsive. Apparently he sat on it and the screen broke.
I then acquired it and replaced the LCD screen and i turned it on but all it shows is a blank black screen with the backlight on. I was tapping while it booted up and it was making that beep noise so i know the touch screen works. What do i do now.

if the lcd is damaged and you only replaced the digitizer then that wont solve the problem, the digitizer just sits ontop of the lcd and recognizes your touches, hence why it mite know that your touching the screen but the screen is still blank

I replaced the LCD along with the digitalizer. Tats what i meant.
Sounds like either the new screen is inop on fit (fraid you need another to test, then send the first back as faulty), or the fault is not the LCD itself.
Possibily its the wrong screen, or its not installed correctly, or you damaged either the screen or the controller when installing.
I'm afraid you dont have many options - take it apart & rebuild to ensure correct parts & fitment, spend £££ on alternative parts to see whats broken (or serious £££ on test equipment!), send it off for repair or give up!
I'd go for option 1 first
If your friend sat on it hard enough to break the screen, i'd be looking for any damage / cracking to the boards / ribon cable mounts and be looking very carefully at the mountings of any IC chips. Incedently, when (s)he sat on it, did the screen work at all? and was it 100% working before they did?
Okay thanks for the replies. I just bought a flex cable where the slider thing is because the old one looked a bit old and flexed out and on inspection of the old screen i found a tiny rip on the screen's flex cable too. I wait for my cable and see if it works and if it doesn't then i'll sent the screen back as faulty and get a new one and if that doesn't work then I'll give up and sell it again
hi
sorry to wake up an old thread.
so what's your solution/conclusion?
is it the flex, or the LCD that broke?
i have the same problem right now.
thanks
was mainboard
I unfortunately smashed my screen and ended up having it replaced by buying an oem screen from eBay. But whenever pressure is put on certain parts of the back of the phone the screen just cuts off. It's got to the point where the phones just sitting there or its in my pocket and the screen will die (the phone is still on as I can see the notification light blinking but this isn't always the case) and I have to push the back of the phone and reset it and after a few attempts this will usually work. Any idea what it could be? Faulty screen? Dodgy installation? (I've checked numerous YouTube videos and as far as I can tell nothing is missing).
I'm tempted to just send it to Google and see what they say as I'm getting pretty fed up with it constantly dying but thought I'd try here first
Thanks
Ok so my Nexus 5 has a real problem with the screen. Started some time after Lollipop, haven't used it since
When I turn it on it only shows "static" screen. It can stay like that or after some seconds purple and white(the white from the Google logo?) but mostly purple going down the screen. When it reaches the bottom I starts at top again(I can see cause the white spot are changing locations).
I have no way to fix it so I just hold the power button till it turns off
Some times (if I'm lucky) the screen is normal (maybe some of this youtu.be/drZc4ZPcuvo) but it works for some time(minutes) until it either turns off the screen(timeout) by itself or it just "jumps" around till the screen becomes black.
I have tried replacing the USB flex cable without luck. I also shattered the glass 1 year ago(havent used the phone for 6 months).
After replacing the USB flex cable yesterday I got it working with just minor issuses. And update to 5.1 etc. (running stock)
But I have however not done a factory reset as I believe this won't fix the phone.
Any good Ideas on how to fix it? Replace the screen (by my self) cost 1/3 to 1/2 of what I paid for it originally. And if its the motherboard/GPU its "dead"?
Better off replacing the device entirely
Hi
I am trying to fix my Nexus 5. Couple months ago I dropped a mug on the phone. The result: cracked screen. I ordered a new screen with the whole front housing so only thing I had to do was remove cracked screen with frame and replace it with new one. When I did it I turn on the phone but I saw only a short blink of the screen. After lots of attempts of I came to conclusion that I probably damaged the new screen or it was already damaged. So the screen is black. When I plug the phone to PC everything works perfectly. I can browse the memory etc.
I would like to ask you whether my conclusion is correct and the only issue is the screen which has been damaged by me or the seller.
One more thing is that when I charge the phone or it is attached to the PC beside the black screen I can not also see any light from notification led.

If the old screen can still display an image, move the parts back to the old screen to check for issues.
HI. Thx for reply. I don't remember whether cracked screen was functional in terms of displaying image. I will try to attache the old screen and will let you know.

My screen shattered rendering the phone unusable (image was fine, but the touch was partially off). So I ordered a replacement and replaced it. At first when I booted the phone with new screen installed, the image was glitching and freezing after a few seconds until I turned the screen off and on. I disconnected the battery a few times during the tests and sometimes the image would not show at all. Anyway, I thought this is the best I can get, I just needed the phone to be usable, so I placed the screws back in and put on the case. The display become kind of more stable - there was still a tiny bit of noise, but it didn't freeze. I set the alarm and went to sleep. After maybe 3 hours the alarm went off, I postponed it for an hour. It was the last time the display worked. Now reconnecting the battery or any other component doesn't help anymore.
What could be the cause? Is the screen permanently dead now?
I doubt this could be a software issue, is that even possible?
Why would it work for a few hours and then just stop - maybe it was just faulty and I should demand a refund?

I think it is more likely to be a hardware issue. Contact service center or from where you got replacement.
Is there anything I could try doing myself? Any clues? If not, then I'll just demand a refund. I don't think I damaged the screen in any way, it was working for a couple of hours and then just stopped.
maybe the parts is broke. or flexible not installe well
