As I was playing with my Zenfone 2 the touch just stopped working.
The phone glitched out with thr flip cover mode and then back to normal.
And it wouldn't respond
Now after two months I've opened the phone and the touch won't work at all .
If I replace the touch screen that would be my second LCD replacement so:
Is it worth replacing the LCD again ?
Is there any possibility that it could be a motherboard issue instead of the touch screen.

that will be completely useless. neither it is a touch or screen issue not the motherboard. issue is either loose screws or bad sim flex. just open all the screws and open cover. close cover and tighten every screw firmly. if still the issue better turn of cover view. or change sim flex

Yeah I've cleaned the cable contacts and also the display cable was slightly folded.
Now touch works but as happen before sim speaker and fast charge won't work because of the faulty sim and data ribbon cable that's just 2$ replacing.
As I've changed two phones ( a Le 2 and now a Redmi Note 5 China AI) the Zenfone will finally replace my mom's crappy MTK6580 phone

noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks

i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board
Got a headache? It's all in your head!!!
Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

I have broken screen on my htc desire hd, i have replaced the LCD+digitizer before. i know my way around this phone.
Is it easy to replace just glass screen ?
I cant see how i can seprate them. they are glued in this black glue thingy.
Better buy whole LCD + digitizer?

I need to do the same. Also since dropping the phone my Bluetooth turns on and off but doesn't always connect. (highlights or ticks option , but I'm not getting anything on the top bar). I disconnect and re-connect a few times to get it working
While I have the phone apart is there anything I can do to fix it?
Sent from my Samsung Galaxy S III using Android Revolution HD
I just replaced the glass only on mine. Unfortunately, the touch screen isn't responding. Anyone know where I might have gone wrong??? Everything else seems to work fine!
Probably a Ribbon Cable.

Try taking it back apart and re-place the ribbon cables back in there seat, they may not be making proper contact. If you replaced the glass without taking it apart you probably un-seated one of the cables. When working on iPhones there is a cable that is only held in place once you close it and put the phone back together.... It's a PITA.
Buy new part and dont replace . Your self its difficult. And its not easy
You can buy a "used" DHD device to replace yours. It'll be cheaper and easier... With a backup on sdcard, your device will be the same !
Just replaced the display panel for my ZenFone 2 because the previous on had a horizontal "dead zone" on the screen. It seems to be working fine except that it won't power on at all if the the speaker assembly is in place. Powers on wonderfully if I leave it out, however.
Any ideas?
EDIT: It won't start with the back panel on either. Also, touch screen is unresponsive with SIM card installed.
I may have damaged ribbon housing on the charging port motherboard while trying to detach the ribbon. Could this be causing my problems?
A friend of mine has a problem with his screen, see pics, it very strange and its somehow related to the SoM not the screen - I ve swapped the SoM for the one in my unit and the problem is cured on his unit but mine has it, I swapped them back and mine is fine but his has this problem.
It was on 5.1.1. and I ve tried several versions of 5.1.1. and several versions of 4.4.4. but I always get the same problem.
Any suggestions ?
Have I found the cause I wonder ? In the attached pic you can see a splodge of solder on what I m going to guess is the video output controller or something.

Who would carelessly drip solder into the unit? if it were to drip somewhere vital it would have fried or fry your car wires, even worse catch on fire.

Theres no solder anywhere else and I dont think it dripped past the lid and the DVD player leaving no trace, I think someone was working on it for some reason or maybe bad quality control at the factory.
Did removing the solder splash resolve the issue?

Not done it yet, gonna try later . . .
I am interested too I've got the exact same problem. Pumpkin send me a new screen even though I've got no warranty anymore and the problem disappeared. Sadly this new screen is without a flex cable for the touchscreen so commands were not possible.

Yes, but the problem on my friend's unit is not screen related.
Why cant you use the cable from your old screen ?

Okay but screen issues are exactly the same.
The new screen has only one flex cable it's working but touch commands are not recognised. And the old screen has two flex cables.
Edit: I don't know if the new screen suffers the same problem because I had it running for only one minute and the screen issues are randomly.

Yes, it did !!
Half an hour of holding a soldering iron to a piece of copper braid and rubbing them over the solder/components covered in solder sorted it !
I used an iron that isnt quite hot enough to melt the solder used on these devices and it melted the solder splash easily, suggesting it was household solder or solder left by someone after the unit left the factory.
Still it was an excruciating half an hour - I thought all that heat my damage the SoM and maybe possibly remove components.

Your old screen assembly is the screen + touchpanel. That is why there are two flexcables. One for the screen, one for the touchpanel. Your new screen assembly is the screen only.
You would have to move the touchpanel from the old to the new screen. However, that could be very difficult when the touchpanel surface is fully glued to the screen surface. If you're lucky the touchpanel is only attached along the edges. Then you might be able to remove it and stick it to the new screen.
Easiest way is to contact Pumpkin and ask them to send you the full assembly, so screen + attached touchpanel.

Pumpkin are just sellers, it may be better to contact the factory direct, mighty be cheaper too.
Yes thanks for your answers
Hello,
Today I disassembled my LG G4 to change the camera. I followed tutorials online and this is the second time I'm repairing this phone.
Previously I've repaired two other phones.
I disconnected all connectors (back and front cameras, display) removed the motherboard from the frame and put the new camera in.
After that I put the motherboard back and connected the things back. The device booted up fine but sadly the touch on the screen wasn't working.
Display worked fine, using a mouse and keyboard I even tested the new camera.
I disassembled and reassembled the device a few more times. The screen connector has no visible damage however the touch is not working no matter what.
I tried starting it without cameras connected, no change.
Any ideas? Am I missing something?

You can try cleaning all the internal connectors with 90% Isopropyl Alcohol but if that doesn't work and you're sure that all connectors are clean & solidly connected, you may have to replace the Touch Screen Digitizer (with frame) in order to solve.
Replacements aren't that expensive - google it for local supply or check out: https://www.aliexpress.com/item/For...lgo_pvid=2fd011e4-25cc-4cd1-a57f-b7878b272ca7
Thing is I don't know if the problem is motherboard connector or screen ribbon.
