Pixel3 touch no response - Google Pixel 3 Questions & Answers

My old Pixel3 board becomes brick twice. I decided to find a good motherboard to replace it and I got one.
After replacing the motherboard, the touch doesn't work, besides that, everything works well. I use a type-c mouse to control it.
Before my old P3 board dead, the display and touch work well.
Is this more likely a software issue or a hardware defect? I wonder is there any way that I can redo the touch panel calibration? I've got root permission with magisk.

i9023 - Replacement screen touch input not working

Hi,
I recently dropped my i9023 and smashed the glass.
Bought a new screen with digitizer from global direct parts (www globaldirectparts com/Samsung-GT-I9023-LCD-and-Digitizer-Assembly-p/smsng6102150.htm)
Having put the new screen in it boots up fine and displays perfectly but the touch screen is not working at all and I can't do anything. If I put my smashed screen back in touch input works fine.
I've flashed back to stock I9023XXKB3 and I9023XXKB1 firmware, but nothing seems to help.
The ribbon to the screen doesn't appear to be damaged and because global direct parts had a minimum purchase of 2 I have 2 new ones and they are both unresponsive.
Anyone have any ideas?
My first idea would be to have the manufacturer fix it.
Sorry you are having trouble getting the touch screen to respond. I too have cracked my screen and would be very interested in your strip down and replacement steps as I am going to be doing the same. If you get time, could you write down your steps. There is a pretty good teardown at
http://www.ifixit.com/Teardown/Nexus-S-Teardown/4365/1
but I am not confident of the last bit of using a heat gun to separate the screen from the frame. Did yours come off easy ?
Yes I could have sent it to an authorized repairer but I would of been without the phone for a a while and it would cost twice as much. Plus I like pulling things apart.
markread544 - I pretty much followed the ifixit guide. however when pulling out the motherboard make sure the front and rear cameras and speaker are loose as well otherwise it wont come out.
I didn't use a heat gun, I just applied pressure until it started to lift, it would of definitely been easier if it had been warmed up but I didn't want to use a heat gun either. You would want to use an adjustable heat one on low if you did, I think a hair dryer would work as well.
I pulled mine a bit further apart then they did, the grey part in the attached pic comes off as well which makes it easier to get the screen out of the front bezel which it is also glued to.
Phone is back together at the moment with the cracked screen but I'll take some photos if I pull it apart again.
same problem here.
i bought an lcd on ebay for i9023 (slcd)
display OK , but no tactil response.
i had MP the OP but still no answer.
if you have any suggestion
thanks
how much for the screen? seems that 9023 is cheaper than 9020
80 euros for the less expensive , about 120-150 for the others
I ended up returning the screens from global direct parts and after about a month they gave me a refund.
After being quoted AU $250to get the screen replaced by an authorized repairer I decided to try again and bought a replacement screen on eBay from a seller called stream_beautiful for $86.
Got it today, installed and it works perfectly. No idea why the original screens from global direct didn't work.
I'm sorry to bump such an old thread, but I was wondering if there was any more information on this issue... I ordered an i9023 screen to repair a friend's phone about 2 months ago and had the same issue as the OP with it; touch input didn't work. I then contacted the seller (forceviewer on aliexpress) and he told me he'd replace it. After sending it back I then had to contact him again and send him pictures of the back of the old screen (with which touch input still works) because according to him there are 2 versions. Now I received the second screen a week ago and lo and behold, it exhibited the same problems. I noticed a number on the back of the screen is different, and the atmel IC (which I assume handles the digitizer input) has a different number on it too, however the seller has now adopted the position that it is definitely the correct display (quote: "If the pictures is right
The item will be right
I just send you the one same with your picturs
There are only two version.
Thanks")
Can anyone shed some light on what causes this? I know the guy's company tests their displays before sending them out, so that's probably not the problem, and receiving 2 faulty units in a row would be a bit weird, so I guess there's actually multiple versions (with a different digitizer controller IC?) which aren't compatible with each other... How do I make sure I'm getting the right one for my friend's phone? And, optionally, how would I go about convincing the seller to take this one back too and send me one that really works?
I'm having exactly the same issue...two replacement screens and touch input non responsive, re-install original and hey presto no problem...what I have noticed is that the part number on what I assume is the digitizer is different...
original -> KJ00423-101228-P00-7F-1
replacement -> KJ00423-101228-P00-5F-1
Yeah, my replacement says 6F-1 at the end, I can't check the original right now because my friend has his phone, but I'm willing to bet it doesn't say the same. Maybe I can make my case with this with the vendor, I'd really hate to have to buy another one of these displays for nothing
Guys,
It's the third SLCD screen that one of my fried is replacing to my I9023 Nexus S, and none of them is working. Yesterday he told me that when he bough the third one, the seller told him to "reprogram" the phone, because the drivers for new SLCD will be installed only then.
To be honest I didn't quite understood him, so, I though that the seller means to flash with a ROM. I did that, I installed CyanogenMod 9, everything went fine, but the touch still not working .
Does anyone knows how the phone could be completely wiped. Meaning everything what is in it to be reinstalled from the beginning....
I don't know what else to do, besides to buy a new phone
Hi All,
Just want to ask if anyone came to the solution yet ...?
Cheers,
no touch
Hello
i have the same problem:
1. The display works
2. But no touch reaction
i had bought a new screen for my I 9023 .
thanks for solutions
Yep, I have the same problem.
Original: KJ00423-101216-P00-1F-1
Replacement: (Not responding to touch): KJ00423-110207-P00-1F1
eBay Seller: mike410512
Bump - anyone sort this issue out?
I know this is an old thread, but since I have a shattered SLCD screen and i'm willing to replace it, i'd like to know what to do in case there's no touch response...
To get touch input again
Hi all,
I have smashed my phone screen twice on my S3 i9300. The first time I had the issue with the touch screen not detecting input but displaying correctly, I had taken it to an authorised repair centre and initially they did not know what was wrong.
There is only one way to "fix" this situation. You must remove the custom recovery and then reflash your phone with the stock samsung rom. Flashing the stock rom with stock recovery should pose no problem as it will be "official" and thus not blocked by stock recovery.
After reflashing, you must do a factory wipe + data reset. This is where you change your screen, making sure not to boot the phone for "the first time". If it does not work, repeat the reflash + factory wipe and try again.
The samsung rom will register the new hardware profile, and touch input will work. Why it works this way is beyond me, but taking these steps when changing the screen on a custom rom will ensure that the touch input works. Perhaps custom roms "borrow" drivers left over from stock rom? I don't know.
You can back up your current rom and restore after messing around with the samsung stock rom and you have gotten your touch screen working properly.
I have tried a whole heap of different "solutions" with this problem and this is the only one that works, and if you are taking it to a repair centre, make them aware that you have a custom rom installed.

digitizer recalibration

hi - I have a htc desire s thats on original firmware. I recently replaced the lcd/digitizer as a complete unit with a genuine replacement part. The phone was working perfectly in every way up until a few days agoo when i noticed that the side volume buttons wernt working, so i replaced the volume buttons as well with a genuine htc part. Now the phone starts up pefectly but the digitizer is not responding to my touches anywhere. Ive checked that ribbons are seated properly several time but still no response from the digitizer. Ive been told that the digitizer needs recalibration, been told to make a "goldcard"...which i did...also use the file "PG76DIAG.nbh" onto the sd card,,,reboot phone...get into the bootloader menu and it should give me the option to recalibrate the digitizer...but i get no such option in there...any help and ideas please..thanks

Touchscreen Is Not working Ater Replacing LCD Flex Cable Connector

My touchscreen is not working anymore after replacing the connector of the lcd cable -> http://www.casestores.com/images/v/20120920/696/CC11CD63.jpg . I recently changed also the mainbord flex cable -> http://www.consoleplug.com/Products...r HTC Sensation Motherboard Flex Cable-A2.gif
It is impossible for me to flash it because my recovery requires the touchscreen.
What can I do ?
You Can Flash Clockworkmod recovery via Fastboot .
It requires no Touch But isnt the best in my opinion But should work.

So you think its a software related problem. The LCD flex cable 23 pins connector which is soldered newly should have no impact on the touch screen, the only function of it is making the lcd work am İ right? İ tried 2 different touch screens without succes. The volume buttons which the connector is on the mainbord I replaced like I said above are working. I want to understand why it is a software related problemen then.

Xperia Z3-Black backlight only,no image.

Hello. I got this Z3 with a broken screen, when I got it it had only black backlight, no image, but the LCD cable on the bottom was cut, so I thought that was why it had no image.
So I replaced the screen with a new one, but the issue remains, no image, only black backlight.
Tried restoring the software with Sony PC companion, updated to latest version, but it didn't help.
The phone boots fine, touch works, I can select options and sometimes I even get audio readouts of what is on the screen, just no image.
Is this a dead motherboard or something else? Because I went through a couple of new screens, none worked, so I'm out of the ideas.
I haven't encountered a case like this before, the screen either works or doesn't, the fact that the touch works and I have backlight puzzles me. No backlight or no touch issues are a common case to me, but this is a new one.
Can someone help here?
Thnx
Same problem....

It's a faulty LCD connector on the motherboard, in my case. Not the connector itself but the small jumper just above it, it gives power to the LCD, it was broken off.
I had it resoldered. Works fine now.
Could ju point me a bit closer whitch one it was?Did you get no image at all or something like the one on my picture?https://drive.google.com/open?id=0Bym65RPW_fIpeXlkX2NTYUw5SVk This is how mine looks like around the lcd connector.https://drive.google.com/open?id=0Bym65RPW_fIpTXZpWTFKby1Ua3c

No image at all, only black backlight ant the touch was responding.
The three square fuses on the bootom of the picture, it's similar in Z3, in my phone one of those was broken off.
Hi guys. I have almost the same problem but inverted. My display and touch is working but i dont have backlight. I can see the screen only if i put light on it.
Maybe u guys have a faulty digitizer responsible for image faulty(no image), better for send repair, flashing new stock firmware will not help
I tried with new digitizer, no luck. Tried jumping the fuse with no luck. Don't know what to try anymore.

Put the motherboard in the oven and bake it for a few minutes, it resold everything, if that's the problem, it will fix it.
For more infos and temperature / time, google it

MTCD screen is displayed mirrored

I am facing a very strange bug since yesterday on my MTCD KGL.
The screen is mirrored, but the touch panel is not. So everything looks like seeing it through a mirror, but the touch panel is still in the correct orientation.
So e.g. a "Cancel" button is displayed as "lecnaC" and is on the right, but I still have to touch on the left to push it.
Even the boot logo and the recovery are mirrored.
WTF???
Do you have an idea what is going on with my unit?
Damn, this thing is not really usable anymore.
Just another "cheap" China product for the bin.
I should have better lit some cigars with the three 100€s...
So out of nothing it mirrord en before not?
Then it's software problem so fixable... flash MCU, flash image.
Everything comes form China nowadays, besides you know the risk if you want to buy cheap unit...

Yeah, did that already. Didn't help. That's why I'm like wtf...
Meanwhile I found out, that when I'm playing with the hardware power button, pressing it until reboot, that's flashing three times, then randomly pressing it short or long, I can change the mirroring from "flip over short side" to "flip over long side". But that's even worse. Did not manage to get it to correct orientation.
I know sometimes you win, but this time I seem to lose heavily.
Thanks pal.
This happened to mine and i couldn't understand what happened...tried every setting and a factory reset with no luck. And then one day it fixed itself. HOWEVER i did read on another forum a display cable comes loose inside and causes this. Just need to open it up and re secure the display cable...
This happened to my mtcb joying unit. I asked the manufacturer and they said it's like the graphics chip.

Normally these use a long ribbon cable to connect the internal boards together and then another to connect the display board to the LCD.
On my last unit the LCD cable was pinched by the metal case, causing random display issues.
Taking it apart and readjusting the cable so it was not pinched solved the problems.
Most manufacturers put the ribbon right at the bottom of the case, so any pressure on the bottom of the LCD can cause issues.
