Hi,
Definitely seems to be a hardware issue. A service center may be your best option.
Good luck!

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

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.

Recently, I took time to replace the screen on my s3. (Just the Screen not the digitizer). After I attached the newer screen, I turned the phone on, theres sound, vibration, etc. But the display is not shown at all. Is it the digitizer that broke? Is it something else that broke?
P.S While I was removing the cracked screen, i accidentally turned on the phone when i was using the s3 phone kit (which was pretty useless imo). Could this have played a role?
Any help is appreciated.
Since the digitizer and lcd are separate parts, a broken digitizer should not cause a blank screen. I have replaced the digitizer on a couple of Samsung phones and the lcd always displayed an image but would not respond to any touches.
Is it possible the lcd is defective?

Sorry for the late response, I was just able to check the forums recently. The lcd was brand new. How would I be able to tell if it would be defective or not? I'll post pictures if necessary.

If you can see an image on the screen, the LCD is not defective. If you can see an image but it doesn't respond to touches, the digitizer could be defective, the phone's motherboard is defective, there is a bad connection between the digitizer and motherboard, or all three.

Does that mean, that I need to buy another screen and test it out? I can't really test out the other parts you were talking about because, the screen does not display any image at all.
Since you can't see an image, it could be the LCD. Is there a repair shop where you could askl them to test your LCD?

I think there is one nearby. Would I need to pay for it to be tested? I don't know if it's still worth getting my S3 fixed because my relative is going to give his note 3 to me since the S5 is supposed to be revealed soon.
I would double and triple check that all ribbon cables and connectors are 100% properly attached / connected before replacing anything else....

I only replaced the screen and didn't touch anything else. I used the tutorials on youtube for guidance, but sadly it didn't work the way i hoped.
Hi There,
I bought a Spring LG G2 LS980 on ebay with an non-working backlight with cracked screen. At the moment, I thought that the screen was broken beyond the LCD and that replacing the Screen, LCD and Backlight it would work. So I bought a new screen and replaced it like any other G2, but now the phone turns on and sounds tell me the phone is working and responding to my touch, but I can't see anything! The status LED is my only indication if the phone is off, booting, on or charging. Is this a software issue or am I gonna have to replace more chips? Thanks,
Sincerely,
Sohaib
EDIT: So i did some testing around, and it seems like the flex assembly with the power buttons gets super hot when the phone is supposed to be on. When I press on the lower right contact between the screen and the assembly, the backlight flashes for a moment, so it looks like the connector is damaged. It is a hardware issue. Thanks,

All the connections are correct....and the phone comes on just the display backlight not coming on.
The funny thing is that when am in a well lighted room or i shine a light on it, i can see that the phone is on an i can access my apps.
make sure that all 4 ribbons in the lg motherboard is properly connected, check if some pins are dent or bended. if all seems to be good, the problem is the backlight of your replaced screen
Make sure there is nothing covering the proximity sensor!

where can i find the connection for the backlight?
Hello, did you find a solution.
I have the same issue, it's not the screen because when I change the motherboard, the brightness work.
Thank you.
The display of my G4 suddenly began to work with this brightness diffusion effect. Once it got stuck and I had to take out the battery, on reboot it did the flaw and now it is. It is not the well-known ghost effect that seems to depend on software, but it is a hardware defect that is already seen at the bootscreen. Will it be a problem that depends on the LCD or the motherboard?
Solved! Changed LCD bought in China. Perfect.
