My Screen Dont Work!!

Hi there, my phones screen will not work, my friend kept opening and closing they keypad quickly after which he gave me the phone back and the screen did not work!
The problem im having is that the touch screen dont work, nothin else is wrong, the screen is not cracked, jus that it dont touch sceen no more.
The bad thing is I put it on boot mode and erased the phone memory, and since the touch screen dont work i can allign the cross thing.
Does anyone know a way in which i could fix this?
Cheers.

Mmmm. Tricky perhaps. A hard reset will either cure or leave you stuck. If you hard reset and the screen is indeed dead (touch wise) then you'll never get past the alignment stage. If the touch issue is software related then you would be sorted with the hard reset.
A gamble I think!!
However you are stuck at the moment so in a sense you have nothing to lose. If it ends up being useless then you are faced with a warranty (hopefully) repair otherwise some DIY though it's not entirely obvious what has broken/come loose - possibly just a ribbon connector.

Maybe the ribbon cable came loose on the LCD side?

Yeah i think its that as well, i hard reseted it a few times with no effect, in the begining of the day, it could still reconise the screen taps around 2/3 times before it totally went dead.
Are there any tutorials on how to open it up to check the ribbon?
Thanks.

This maybe the hardware problem with the mainboard itself. I read about this on here a few times, most people had the get their phones exchange....

Yes, I am equally unsure that this is just a simple loose connector. It may be, but it appears to be fine for a short while and only then goes off.
Like you myztikal47, I suggest going for warranty replacement if at all possible. Only if you have no warranty shuld you attempt a repair yourself - this is a notoriously ellusive fix and indeed I would say there is no 100% works for all answer. Certainly do not assume it's the screen - most probably it isn't and you'll waste your money.
There are dismantling links in this forum - but you'll find them on my small Hermes site http://michael-channon.spaces.live.com- go to the loose keyboard section and you'll see the links.

my 8525 had the same exact problem, and i swapped the LCD and still doess the same thing...
I dont know what the problem could be, and i dont have a warranty.
What could be going on????
Any 1 know where 2 find the service manual????

[Q] Problems with Battery on i9505

Hi,
I recently got my phone repaired after a broken Charging connector which broke due to a short circuit with water in the charing cable.
Now it got repaired and it charges again, but it sais it keeps charging even if it is not attached.
the Menu and Back buttons aren't working aswell. USB isnt working either, but when i remove the battery it does work suddenly.
Did the battery could be damaged and how bout the menu and back button?
If you got questions, ask me!
I flashed my Phone back to stock so i could be sure it is no problem with the kernel/firmware.
Hope you can help me out!
Regards, D

No one knows an answer to this?
could the buttons be broken when the guy changed the connector slot?

They say that they haven't touched it and that the screen has to be replaced. They are not going to replace it they say...
Is this a hardware problem or a software problem?
Thanks in advance!

Whats wrong with the screen, did you drop the phone? If you reflash the stock rom you have with Odin 3.04 and do a data factory reset after the flash and the issue persists it is definately a hardware problem.

The bottom buttons / softkeys ( next to the home button) do not light up anymore and do not work at all. This problem showed up after they have repaired it. They told me that the screen might be broken(the buttons are part of the screen they told me) so if they need to be replaced, the screen has to be replaced.

I guess they think you dropped the phone, which is not covered by warranty.

[Q] Broken Screen on my Nexus 4

Hello,
I dropped my Nexus 4 (EG960) couple of months ago, ordered a new LCD + Digitizer and started to replace the screen myself.
Everything went just smoothly, I removed the broken screen, put the new one, put everything back together, slowly and safely connected all components, turned on the phone and.................
Guess what? The phone is turning on, but I can only see stripes of different colors all over the screen. I can see that the Google animation is working in the background and that the phone successfully booted. I can actually still see a line where the previous crack was.
I tried reassembling and reassembling everything slowly but still see the issue.
I can attach a picture if needed.
Am I missing anything?????
Thanks,
Liran.

Anyone?

Well it's great and all that you took apart and put back together but I'm not a big fan of repairing screens, digi,etc I think no matter who fixes it will never be the same as before if you could I would try to sell it and just get another one.. Or take it to a professional and try to get a warranty with repair.. Just a thought..
Sent from my Nexus 4 using XDA Free mobile app

And still I did, and wonder what to do next. If to try and replace other components or just give up.
Option 1 is more suited to me.
Thanks a lot

Same thing
Does anyone know a solution to this problem? I replace the screen, the same problem.

We can just guess.. Maybe you damaged a flex cable or a connector/plug. If the problem persists with a second screen then I think its something on the mainboard as suggested..

maybe this helps?

[Q] Screen flickering, what should I change? Screen or Motherboard?

Hi guys, if someone here suffered from this kind of flickering >>VIDEO LINK.
How do you managed to fix it? What part did you change, the screen or the motherboard? Thanks. Really need some help. My phone now is unusable.
]]]]]] UPDATE 1[[[[[[[
Hi guys, just got my G2 back from the dead.
I send my G2 to a phone care in the city and they said my lcd is the problem, they changed the lcd+digitizer (the whole half of my G2 )and now the problem is gone. But When I got home I noticed vertical lines on my G2 when it is turned off, not really noticeable but if you look closely you can see the vertical lines and thinking that they change it with a low quality LCD. Even in white backgrounds you can see the lines but only if you have a clear eyes . I compared it to the original LCD and I don't see any vertical lines at all, it's all black. But the frame of the new lcd is solid like the original. So, in the future, will this new LCD survive or should I go the phone care again? Thanks!
***********UPDATE 2************
[UPDATE]
I think my G2 is working now after playing games for hours in 5 days, no flickering/stuttering/jittering noticed.
But, my IMEI was change and it was rooted jellybean when they give it to me. I don't know if they change the motherboard or the whole phone except for the body case and the new screen i purchased. I asked them about the changes of the phone because it's my second time returning the phone and the women on the counter said their tech just adjust something. I don't believe that, and then I saw the IMEI changed. I didn't ask why my IMEI was change, i'll wait til something goes wrong on my G2 and sue them. LOL.
I have some questions regarding this.
1) I'm not really sure if how an IMEI was change, is it for changing the motherboard?
2) Is it legal that they don't tell me what they change on my phone?
For now my G2 is still alive and no problem after upgrading to lollipop + root + twrp. Hope it goes all well now.

i went to lg service and they changed some filters on motherboard in 2 hours filter,EMI/Power 2 quantity i read on the paper. i was on warranty..

That looks crazy, it definitely would be a motherboard issue, or, I had a simliar issue while repairing them (I've re-sold about 20 of them) the flex ribbon sometimes gets dirty, or out of place(the one on the bottom under the speaker). You have to remove the back, then remove the speaker(6 screws I believe on the bottom, it;s an L shape). Once you do that, make sure the square flex cable is connected well, and there is nothing touching the circuit right under it(It has a plastic tape to keep it from touching).
The connector I'm referring to is right next to the USB one on the flex. For obvious reasons I got the image from ETrade supply. You can clean the connectors with 91% or higher alcohol, DO NOT use anything less.

When you replace your lcd they always tell you to make sure you have both connectors securely in place above the usb connector. One of them is the ground connection to your LCD!
Make sure both are fastened correctly and test before you seal your phone back together.
Keep us posted

After few days of youtube and playing games, my phone started stuttering/flickering again like on my first post -_-
I paid for the new LCD that they change, should I pay another bucks for the motherboard problem? or they'll give me a refund for the new LCD I bought that didn't fix my problem? Please someone reply me asap. Thanks

This error is on mainboard. Fix it is very simple. I has lot about 10$ for this solution.sorry bbecause my english's bad.

Hi guys, i have a similar problem. I bought a new lcd on aliexpress.....that is the video of the problem....
http://www.mediafire.com/watch/glzqihgdzz12jsj/Lgg2_lcd.mp4
The strange thing is , not in every operation make the same problem. after days i see that problem usually on facebook and a lot on clash of clans .
I make also a screenshot on the clash of clans and when i open the picture the screen flickering .....
its like when the phone show some combination of color make this problem

My Lg PRO 2 Phablet did the same from first turn on, flickering on and off, very dissapointed as i had mine direct from Hong Kong and couldnt send it back. What i did was to tak all of the screws out and take the plastic back off, then re fitted the back only, no screws and turned on, no more flickering. Then i put a couple of screws in and tried again, still no flicker, then after a couple of more screws by the sim socket it started to flicker again! Now i just run the phone minus a few screws, it must be a pressure thing!

Hi, i have exactly the same problem, specially in combination of colors (green red and blue most of the time). how did you manage to fix your phone ? did you change the mainboard ? thanks for your help.

Half Static Screen - Connector Not Loose

Hello, I have had my Axon 7 for just over a year and two days ago the screen went suddenly half static despite the touch still working perfectly. I looked up the issue and saw that this is pretty common and that my display connector was probably loose, so I opened up the phone to make sure the connector was fully connected. Well, I booted the phone and the static was still there, so I unplugged and reattached the connector, but that didn't help either.
Given that ZTE is bankrupt and my phone is out of warranty, is there anything else I can try at home to fix this or is my phone screen just dead? I'm in California, is there anyone who could possibly fix it in the state?
Thanks for your time!

Try pushing the connector down while it's booting and see if that fixes it.

Alright, I'll try that. If it needs constant pressure I'm probably going to need to glue it or something?

Tape could also work. I added tape to my back up Axon so it doesn't happen again. You could also add something so the frame can push against the connector.

Hey, unfortunately, pressing on the connector doesn't change anything with the screen. I even tried disconnecting it and cleaning out the contacts with a can of compressed air. None of this helped.
What are my next steps? I'd really love to get this phone working again.
Thanks!

Probably playing with the wrong connector, the half static screen is common problem, ZTE repaired mine a month ago as they are still actually operating. They said it was a connector and that they put something in there to make sure it doesn't move again.

Hey, that's possible, though when I unplug this connector the screen goes completely dead. Here's an annotated image of the connector I've been messing with and the foam pad that was installed on the back of the phone, I believe to keep it in place (my phone was bought in March 2017).
https://imgur.com/0d7C2xc <- That's an Imgur link to the photo, I can't seem to get it to show up as a hyperlink or embed it into the post.
Is this the wrong connector?
Thanks!

Yep that's the connector. I'm sorry to say but it looks like the screen is toast. I seen some Samsung Galaxy S7's that have the same issue but couldn't be fixed without a new screen. And since the Axon uses a Samsung screen, that might be the issue.

Is there a place to get Axon 7 parts? I am not planning on using it as my main phone again, but if I could get a working screen I think I'd use the phone for something else. Are there any other screens that use this connector?

Aliexpress has screens for sale, they came down in price the last time I checked.
