Hi,
My Zenfone 2 (ZE551ML)'s screen was more and more unresponsive, so I decided to replace it myself.
I bought a 5-stars rated one from aliexpress (not the cheapest, right model, trusted sellers, 100+ reviews on this product).
I carefully replaced the screen using the right tools.
My Zenfone boots OK, the new screen display is OK...however it is totally unresponsive!
I tried a factory reset: same problem...
I rechecked every connection 5 times (especially the 2 ribbons of the screen -one connected just above the battery, the other one to the motherboard): same problem...
Any idea of what could be wrong? Or is it just simple as connecting the 2 ribbons stated above? A ground issue?
Thanks a lot!
Regards,
Doen the phone work any better with the old screen? Maybe the replacement is defective?
I bought a cheap screen from eBay and had no problems after replacing my busted screen.

Hi,
thanks for your reply.
Unfortunately the old screen is useless since I cut its ribbons to ease its disassembly...

Hey guys!
I'm experiencing a very strange and annoying issue with my BA, and I was wondering if I could get some input from you.
So, here goes:
The touchscreen (not LCD) in my unit was broken, and thus I decided to fix it. I purchased a new one off eBay a few weeks ago, and just yesteday I proceeded to install it. To my surprise, something seems to have gone wrong.
I power up the unit, make my way into "Allign screen", and then the last "cross" that I have to touch rarely clicks in. On the other hand, when it does get detected, it simply restarts the alligning process.
What I've tried so far:
- allign right after installation -> no luck
- hard reset (on WM2k5_v4_R2.1) -> no luck again
- opened up the unit again, repositioned the screen -> nothing
- upgraded to Logout_WM2K5_5.4.03_HN -> still nothing
Right now I'm out of ideas, and I was hoping somebody here has some. Do you think the new touchscreen might be flawed ? I'm already discussing this issue with the seller.
Thanks for reading
New touchscreen or a refurb? Same type? (toppolly / sony) Sounds like it's been stripped from an old unit to me as it's not recognising the taps in the right places - can you see somehting like a liquid spill anywhere on the panel? This is what it looks like when the overlay touches the glass.

That was in fact my auction. Looked like brand spanking new to me, not one single stylus mark, and also had the protective sheet on. Of course, I might be wrong
Also, no liquid spill visible anywhere.

I bought from him also and am yet to fit - I got the completley wrong module :-(
Richard
What do you mean wrong module ? The "tip" of the flex cable ? Mine seems to match with what was already there ...
Hey NSD!
I purchased the exact same module for my Himalaya device, after the touchscreen being cracked.
My father, who is an electronic engineer, soldered the flat wire from the touchscreen onto the rear side of the LCD with normal copper wires. Unfortunately I have the exact same problem a you!
After attaching the entire LCD (+touchscreen) onto the mainboard, and supplying power from the battery, I'm not able to go past the Align Screen section!!!
The touchscreen is from the manufacture 'Asian Media' (I think so...).
It can't be a coincidence, that both of our touchscreens don't respond to tapping!!!
Anybody been able to get this problem fixed??
Any help would be appreciated!!!
Kind Regards,
Tony Schattat
I never replaced the touchscreen of my BA but I have replaced the screen of my ex ipaq 6315 once.
And one thing that I know is that sometimes the screen align process is different from the normal, I mean, it keeps repeating and repeating again many times....until the unit finally passes the align step and finishes the configuration. Actually I´ve "aligned" the screen more than 30 x (when I replaced the screen).
It happened just once and then I had a completely normal unit.
Hi Guys,
As others, droped my phone and broke the front digitiser glass so got one of ebay and tried replacing it. after replacing it i could not see anything on the screen, I could atleast see something before.
so I thought screen was broken so replaced the screen but same thig. Ii vibrates when i power up, even charges and my PC can see the phone when I connect it
Just wondering if it could be any cable although I have opened it few times and made sure cables are connected properly
any help will greatly be appreciated
regards
Looks like no one knows the solution!
would any one know any good repair shop in London or England?
regards
i have the same problem, do you already find a solution for that?

Necropost! C'mon really? I'm closing this.
After dropping my desire the screen had an obvious crack (no crack in the glass/digitiser) and displayed crazy colours from the crack, spreading across the screen over the course of the day until finally going completely blank.
Bought a new screen on ebay, same part number, same samsung AMOLED. Replaced today and the phone exhibits exactly the same behaviour. Switches on, digitiser works to the extent I can unlock and lock the phone, but screen is constant black. After a few switch on/offs the screen showed two green lines at the top and about half way down upon unlocking, that went away after another lock and unlock.
Pretty confident that the disassemble/assemble went ok and I didnt stress any flex connectors or similar... so have no idea what could still be wrong....
As I say, phone boots and can unlock/lock (makes the right noises etc) and is recognised by computer when plugged in.
Could using the phone until the screen completely stopped working have broken the controller or something?
Any input greatly appreciated.....
EDIT:
Just switched it on again, green line at top from keyboard lighting point, then the whole screen went blue on unlock. :S
This sound like a dying something, or maybe just bad contacts? Find it strange that unlocking has an effect....
Might be a bad connection or little shortcut?
Here is an official video on how to assemble and disassemble the device, http://forum.xda-developers.com/showthread.php?t=768535. Don't know if that helps but you can check if you did something wrong in the progress.

Seeing as the part was shipped from my country and had the exact same markings and serial numbers as the part I removed, I dont think this is the issue.
Thanks for the video, will disassemble and clean all contacts later today.
Was mainly posting to see if people had heard of/experienced the same issue, trying to ascertain whether it could be a faulty replacement or if its possible to break the hardware that runs the screen.
A good fake can be hard to tell apart from an OEM part...
So the consensus is that its a fake replacement? Really? The screen seems identical in all markings and connectors, my only conclusion can be it came from the same factory. What market would there be in producing defective replicas of mobile phone components?
Anyway I have sent the screen back to the seller for a replacement.
Any response to my other questions? Is it possible to damage the hardware that drives the screen by using the phone with a dying screen to the point of blank display?
Reading through another thread: http://forum.xda-developers.com/showthread.php?t=933866
Post #6 suggests the rom on the phone could have an effect, is this the case?
Thanks for any input.
Rom couldn't be the issue if you've installed the exact same screen.
My guess would be a loose connector.

Replacement screen worked just fine....
Thanks for everyones responses!
Can you post the link to the seller on ebay, from whom you bought the display?
hello guyz!
my samsung galaxy 3 i5801 display got damged recently!so i took my cell to local samsung cervice center! he said that the display screen is not available! so he replaced my damaged screen by a duplicate screen! the problem with this screen is it shows different colours when seen from different angles(basically its a TFT screen i guess)! this really hurts my eyes ! so i am planning buy a new screen where can i get one?
i search them on ebay and i found some!but i could not decide which one to get! all are for i5800 and mine is i5801 ! i guess it dosent really makes any difference! As i am not allowed to post urls please search "Display Screen For Samsung Galaxy 3 i5800" on ebay.com and tell me which one to buy!
Thank you!
How much did you spent on replacement LCD ?
Did samsung guys sold you a duplicate/non-company authorized screen, this would be the strangest thing I heard about any company service center.
I don't think you should be buying it off Ebay without knowing about details of screen and a couple of reviews about it.
I recently saved my Galaxy 3 as it suffered from non-functional touch screen and a broken volume button connector, had to fully dis-assemble and do the stuff to fix it.

Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
I`ve got the same problem. Have you found a solution?

Yes, it seems that the display units from HOX are not all the same. You have to check with display flex you have and compare it with the one you have new. I tried an other display unit and it worked for me.
Now i have the same problem for my friends HTC One X. Were looking now for the right display unit..

Ive swapped a few screens over on the one x and x+, I find the screens don't show anything until the phone is soft reset by holding down the power and volume up button for around 10 seconds (until the lights flash several times and then the phone vibrates before booting).
I have also found that the motherboards do accept displays manufactured by different companies (sharp, sony, AUO.. etc) the soft reset is a required step. If an identical lcd is used there is no need to reset.
Hope this helps!
