I recently got a touch pro of a friend with a damaged screen that didn't turn on but the touch screen was responsive. Apparently he sat on it and the screen broke.
I then acquired it and replaced the LCD screen and i turned it on but all it shows is a blank black screen with the backlight on. I was tapping while it booted up and it was making that beep noise so i know the touch screen works. What do i do now.

if the lcd is damaged and you only replaced the digitizer then that wont solve the problem, the digitizer just sits ontop of the lcd and recognizes your touches, hence why it mite know that your touching the screen but the screen is still blank

I replaced the LCD along with the digitalizer. Tats what i meant.
Sounds like either the new screen is inop on fit (fraid you need another to test, then send the first back as faulty), or the fault is not the LCD itself.
Possibily its the wrong screen, or its not installed correctly, or you damaged either the screen or the controller when installing.
I'm afraid you dont have many options - take it apart & rebuild to ensure correct parts & fitment, spend £££ on alternative parts to see whats broken (or serious £££ on test equipment!), send it off for repair or give up!
I'd go for option 1 first
If your friend sat on it hard enough to break the screen, i'd be looking for any damage / cracking to the boards / ribon cable mounts and be looking very carefully at the mountings of any IC chips. Incedently, when (s)he sat on it, did the screen work at all? and was it 100% working before they did?
Okay thanks for the replies. I just bought a flex cable where the slider thing is because the old one looked a bit old and flexed out and on inspection of the old screen i found a tiny rip on the screen's flex cable too. I wait for my cable and see if it works and if it doesn't then i'll sent the screen back as faulty and get a new one and if that doesn't work then I'll give up and sell it again
hi
sorry to wake up an old thread.
so what's your solution/conclusion?
is it the flex, or the LCD that broke?
i have the same problem right now.
thanks

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 ???
My phone freaked out today and the right side of the screen is non-responsive. It played havoc with the lock screen and once I got in, it was opening apps and switching from one thing to another as if someone was touching the right side of the screen. I was running the SteelEpicBlue V4 ROM, so I had to reflash back to Cincy Bell ROM before taking it to the store.
For those with the Otterbox, has anyone experienced touch screen sensitivity issues? I took the screen protector portion of the Otterbox off to see if that was an issue, but it didn't fix anything.
I have the insurance, so I hope the replacement XT720 doesn't have the same issues.

I assume the problem persisted after flashing back to the stock ROM? To me it sounds like a hardware issue. I think you'll be fine with the replacement.
The phone wasn't acting like it was experiencing random screen touches, but the keyboard still wouldn't recognize touches to the "p" or the "b" keys (in portrait mode, anyway).
I know this is bringing up an old thread, but relative to the problem stated above, I got a replacement XT720 several months ago, yet the replacement is now doing the same thing. Using the stock keyboard, I cannot use the p/0 key and expect it to freak out like before in the next few weeks. No one else has seen this issue?
Hi,
some time ago my digitizer stopped working - there was visible a small dark spot, which resulted in erroneous signals to my Raphael. I replaced the LCD and digitizer with a new one, but still there is something wrong - Raphael does not respond to touch - tapping the screen doesn't cause effects. But if the screen dims, touching it restores the normal brightness. And what is strange that Raphael sometimes restore brightness immediately after getting dim, and this cycle repeats over and over again.
I uploaded new ROM, then the stock, always the same. I have no idea what might be damaged, any idea? A relay, tape, cable...?
Thanks for any help.
Ok, I know everythink. It's broken flex tape connecting LCD and mainboard.
My desire s is a year old, rooted and running endymion. Recently I applied a matte finish screen protector. But suddenly starting from yesterday, the touch screen near the pull down notification bar became totally unresponsive
I can't pull down the notification bar, also the touch won't register in that region when playing games such as fruit ninja. So till now, I've tried rebooting, restarting, factory/data wipe and install a new rom (blind ice) inset and still the touch problem exists.
So I'm guessing this is a hardware related problem? ( secretly hope it's not). I'm sadly out of warranty too.
So does anybody out there have any fixes/solutions/ideas?
Thanks

did it work removing the protector? i get a similar problem with my wifes ds from time to time and wondering what it is about
I believe that this could be a hardware issue as one off the hundred units that my offices ordered had to be replaced as the same thing happened, soft and hard reset (full data wipe) didn't help, got warranty return
