I purchased a Tornado a little while ago and didn't vet it properly first. It was descibed as having a cracked screen which was actually a cracked LCD. I have replaced but I get only a white screen on boot. The unit works fine other than this as I can connect via BT and USB. I have been able to verify that the file system is fine. I am assuming water damage and am going to try the DISTILLED WATER / COOK solution, but before I do...
Now, being aware of my status here, I can only make an offer to anyone with expertise on this. If anyone thinks this a problem they can resolve I am either happy to sell them the phone, take their advise and split the profit when I resell it or send it for paid repair.
Any takers?
Thanks for taking a peek at this thread.
P.S. Please, no remiders of my remiss behaviour when purchasing it. I have already kicked myself half to death, thanks.
A white screen normally means the ribbon cable to the lcd is not inserted properly, make sure the white lines on the cable and the main board are lined up. I've had the same problem.
have had the same problem with htc tytn, p4350.
after reboot its okey again
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.

i'm going to buy a screen + digitizer and i would have some advice about this, what code should i look ??? there are only two kind of screen or more ? what should i ask to the seller ???
Hello, posting here to report that I attempted to repair my HTC sensation, though I didn't really break anything and taking it apart when kinda smoothly I ended up putting the phone back together somewhat was more difficult than I thought it would be. Question here is that the phone turns on but the LCD isn't working still. I had to replace both LCD and digitizer...it vibrates to turn on but nothing could it be that I may have not secured a cable tight enough?
Hello guys,
i hope you can help me with my problem. (also my english is pretty broken :/)
Little Background:
I crushed my screen but the lcd did still work. Another time my phone fell a 2nd time to the ground
resulting the cable for the touch sensor beeing ruptured. To repair my phone i ordered a new lcd,
but when i tried to connect the new lcd to the motherboard i dont know how but i broke the other plug responsible
for the things i see on the display.
In the end i can't navigate the phone anymore without seeing anything what i would do, so i don't care for the phone anymore but does anyone know how i can safe my storage?
I guess i can still boot the phone normally aswell as access recovery.
My phone is rooted, s-off and with the carbon rom 4.3.
Would be glad about any help, since i cant get htc support cause i lost the sticker with my imei number aswell threw the package away.
Sincerely,
Masern
Hello,
I've had recently broke my XT925 and have question if it’s possible to bring it back to life...
Well from the beginning... I've had glass smashed and during tearing screen from the glass I damaged it, so I've ordered new screen with glass and digitizer. When it arrived, after putting it all together it appears that screen doesn't respond on any touch. My friend read somewhere that it could be solved by flashing the phone again(now I don't know is it truth, and right now it feels like one of the smallest problem I have).
I flashed my Milestone 2 and Droid 4 before so I didn't suspect it be so troubling now.
Because my Motorola had been updated to 4.4.2 and I couldn't find firmware in that version I've decided to downgrade the version to 4.1.2. I found some video with how to modify XML file to be flashable. Unfortunately the video is in foreign to me language (Spanish I guess) and at the time I don't realize, that phone has to be unlocked to do that.
It, start to flash, but when it gets to "boot" it stop saying that it can't be downgraded. So right now My XT925 starts to AP Flash mod with text Flash Failure. I'm able to get to recovery mode and from there try to update phone but like in AP Flash it just don't want to flash Android 4.1.2.
Is there any way to bring it back to life?
I'm guessing that it should run if I could flash files for 4.4.2 but I don't know from where I can get them...
Please tell me do I have nice looking brick or there is a hope for my phone?
Phone is locked, has no other then stock tools installed, and it had system version 180.46.117.XT925.CCE-Retail.en.EU before I started to mess with it.
I tried flash it with 9.8.2Q-8-XT925_VQU-22_USERSIGNED_S7_UCAVANQU02NA02F.0R_LSAVNQJBRTFR_P007_A004_CFC.xml. When it begin starting in AP Flash mode I have removed every line that cause stopping the process (technically everything except "partition", "tz", "boot" and "system" is loaded from 4.1.2) so now its very messy. Right now I don't know what I was hoping for. What's done is done, so now I can only hope that it can be fixed.
If its even fixable, there is no way to fix it without the stock kk fxz, unless you can get it unlocked using Moto's site.
Sent from my G3 Rockin Cyanogen
Thank you for your reply.
I'll try unlocking by web when I get home. I'm only hoping that it can be done without working properly touch screen, or buy connect keyboard via OTG. Otherwise I'm doomed...
Why the F would reflashing after changing the screen and/or digitizer magically bring back the touchscreen functionality to life ?
No touchscreen only means the digitizer was not installed properly, that's all. Open the phone again and check all flex cables and connection, they are really tricky to put back in connectors properly. (pro tip, use some very small pliers to manipulate flex cables and put them back in their connectors)
Unlocking does not require any touchscreen functionality though, it's just a matter of keyboard input from your computer. Just unlock, downgrade properly to say 4.1.2, and when you're done see if the touchscreen work. And when you find out it doesn't, tear the phone apart again and double-check all flex cables connectors on the motherboard
It works!! Thank you very much!!
At first I have problems to find the fastboot.exe in the downloaded SDK directory (for those who also have problems with finding that file it is in 'sdk\platform-tools' folder). The process of unlocking is very easy so I have no problem with that . After unlocking phone flash correctly.

Apparently when you have KitKat update it's necessary to flash phone again after replacing the screen and/or digitizer. After flashing digitizer is working properly. I didn't need to open the phone and correct any flex cables (there is only one common to the screen and digitizer so if that was wrongly connected probably I won't be seeing anything). To be honest I don't think that will work without opening the phone. I instinctively unlocked the phone and started to choose the language. Then I realized that I can do it. I'm really glad that the phone is working correctly.
Once again thank you very much for your help.

Well, I'll be damned, it's the first time I hear of such behaviour, and i've ripped apart a long list of devices before my razr... Sometimes to replace the screen, sometimes to replace the battery, sometimes just for fun... and I've never seen that before.
(Although IIRC there are two flex cables going from the front assembly to the motherboard in the xt925 and not just one, but I don't remember which one is for what)
edit: OK just found out lcd and digitizer are glued together in most recent phones, including xt925, so there's probably only one flex cable for the whole assembly. They other one was probably for the led I guess...)

The second one is for front camera, speaker and light sensor. I don't count that one because is actually separate part from the screen witch is screwed to the front frame of the phone. To be clear I had problems with that cable and I had to put it few times before camera and sensor start work correctly. That is why I paid special attention to the good fitting of these cables to the motherboard. That was before I smashed software by trying downgrade locked phone so I was pretty sure that it was fitted correctly.
Now my Motorola still works fine. After replacing the screen it actually lived longer in one piece then when I bought it. I scratched the screen next day from purchase... then it fell of my hands few times(usually with the help of other people)... That is why I decided to change glass and front frame... and then during the peel-off old glass from screen I broke the screen... It all happened in period shorter than two months... I'm guessing this particular XT925 is very unlucky... or... it's just unlucky to have me as the owner...
I'm very careful with carrying it with me now, so I don't have to replace the screen again... it cost alto... :|
Well, at least now I know how to bring it safely back to life. And I must admit that my friends are quite impressed that I managed get it work again.
